Depending on the job requirements and specifications, different finishes and techniques may need to be applied when texturing drywall. To help contractors in the industry better understand the requirements of architects and building owners in order to enhance the satisfaction of the client, the consensus document ‘Recommended Levels of Gypsum Board Finish’ was created by five major trade associations: The Association of Wall and Ceiling Industries International (AWCI),the Drywall Finishing Council (DWFC), the Ceilings and Interior Systems Construction Association (CISCA), the Painting and Decorating Contractors of America (PDCA), and Gypsum Association (GA). The purpose of the document was to accurately describe the desired finish of walls and ceilings prior to final decoration. This also helped promote competitive job bidding that allows the bidder to consider the correct labor and materials to finish the wall suitably for its final decoration.

To refresh your memory, in this blog, we are going to briefly summarize the different levels of drywall finishing.

Level 0

No taping, finishing, or accessories are required for the job. This level of finish may be useful in temporary construction or whenever the final decoration has been yet to be determined.

Level 1

This level of finishing only requires a single coat with taping set in joint compound on all joints and interior angles. This level is typically specified for jobs in smoke barrier applications, plenum areas above ceilings, in attics, in building service corridors and other areas where the assembly would generally be concealed or in, and other areas not normally open to public view. Although it is not much, there is some degree of sound and smoke control is provided.

Level 2

This level involves a double coating of joint compound over all joints, interior angles, fastener heads, and accessories. This finishing level is commonly used for non-finished areas and areas where gypsum panel products are used as a substrate for tile. Examples of application locations include warehouse storage, garages, and other similar areas where surface appearance is not a concern.

Level 3

This finish requires that all joints and interior angles have tape embedded in joint compound with one thin coat applied over them, plus two coats of joint compound on fastener heads and accessories. This results in a smooth, ridge- and mark-free surface that is ideal for residential interiors and similar areas which are to receive medium to heavy texture (spray or hand applied) finishes before the application of paint, or where heavy-grade wall coverings are to be applied as the final decoration. Keep in mind, this finish is not recommended where smooth painted surfaces or light to medium wall coverings are listed as job specifications.

Level 4

Drywall contractors applying this level will have tape embedded in joint compound with two separate coats of joint compound covering all flat joints and one separate coat of joint compound applied over the interior angles. Three coats of joint compound should be applied to fastener heads and other accessories. This level is most common in applications where flat paints, light textures, or wall coverings are to be applied. There are some paints that are not recommended for this finish, including gloss, semi-gloss, and enamel paints.

Level 5

This level requires that all joints and interior angles have tape embedded in joint compound, with and two separate coats of joint compound over all of the flat joints, and one separate coat of joint compound applied over the interior angles. Like level four, all fastener heads and accessories should be covered with three separate coats of joint compound. Also, a thin coat of joint compound needs to be applied to the entire surface. This level is typically recommended where gloss, semi-gloss, enamel, or non-textured flat paints are specified or where severe lighting conditions occur. Out of all the finishes, this is of the highest quality and is the most effective for applying a uniform surface and minimize the possibility of joint photographing and of fasteners showing through the final decoration.

There you have it, the different levels of drywall finishes. These are important to keep in mind, especially for jobs that have certain specifications. While these textures can be applied by hand, it is definitely easier and more efficient to use a texture sprayer.

Texturing walls and ceilings has increased in popularity in both residential and commercial settings due to the decorative applications and patterns the material creates. Before beginning your texturing jobs, there are many factors that must be considered in order to achieve the desired texture and finish. Some of these essential considerations include the texture spray equipment used, nozzle selection, airflow setting, material flow setting and the actual material that is being applied.


One of the most crucial steps in texture spraying is mixing the material properly and paying close attention to its consistency throughout the duration of the job. In today’s blog, we will review some of the different types of texture material, pattern sizes, and helpful guidelines to keep in mind for mixing and equipment. Before you know it, you’ll be spraying texture like a professional in no time.


Common Types of Drywall Spray Material

Typically, drywall texture material can be purchased in a pre-mixture or powder form. No matter which type of material you are using, you must mix the material and thin it until the proper consistency is attained. This is a vital step to achieve the best finish in your spraying applications. Let’s expand upon the characteristics of the two types of texture compound.


Pre-Mixed Drywall Material

This drywall mud starts with a thick, paste-like consistency. Commonly found in a bucket or box that has everything needed. Keep in mind, most pre-mixed drywall material needs to be thinned to meet pattern criteria. This drywall material offers convenience and will require less mixing and less water to reach the desired consistency, but on the flip side, normally incurs a higher cost per coverage as compared to powder.


Powder Drywall Material

Powder drywall material is most commonly used for wall and ceiling texture application. This material will need to be thinned according to the manufacturer’s instructions as well as the contractor's preference for the desired pattern being sprayed. Powder or bagged material is used most commonly because of its lower cost compared to pre-mixed. An American Spray Technologies spray rig can mix this material up rather quickly.


Remember, generally, the thinner the drywall mud that you use, the more output and finer finish you will get. On the other hand, thicker drywall mud creates less output and a coarser finish.


Tips For Successful Drywall Spraying

Follow the tips listed below to help guarantee your success with drywall texture spraying jobs!


Use The Proper Mixing Tools

This one is simple for big rig owners as AST rigs have integrated mixing systems. If you are spraying with a portable unit such as the Kodiak M2, you will have to choose the right mixing tools in order to achieve the proper consistency. Using standard drills to mix the heavy drywall muds can risk damage to your equipment. When mechanically mixing material, it is best to use a heavy duty drill or a mixer designed exclusively for texture and drywall material that provides enough power to get the job done right.


Test Material Consistency

Mixing texture material to the right consistency is essential for a successful overall finish. An easy way to test the consistency of your material is by using your finger. After mixing, simply run your index finger through the material to determine its consistency. When the material does not fold back on itself and a line where your finger was is visible, this is an indicator that the material is too thick. Ideally, the material should fold back on itself, indicating you have a light to medium mixture.


Mix Material Frequently

As drywall material sits, it will begin to thicken. When material thickens it can slow down production and impact the consistency of your finish. Mixing the material frequently will help you maintain the proper consistency and aerates to keep the material fresh as you finish the job.


When applying drywall material, in addition to properly mixing and achieving the right consistency, using the right texture spray equipment is essential to the success of the job. That’s why many drywall contractors prefer using drywall spray rigs from American Spray Technologies. Our texture spray machines are designed to last and provide years of profitable use. We make only hydraulic controlled texture spray rigs, which provide infinite control of mixing speed and pump speed at your fingertips. This makes mixing a snap and adjusting your spray pattern a breeze! If you are interested in learning more about AST drywall spray rigs, contact our experts today!

When building a home or remodeling, people often focus on what type of countertops and cabinets they want in their kitchen, the number and size of windows, or the square footage in the new space. With so much focus directed to the major aesthetics and space, people typically put little thought into one of the most integral parts of their space — the interior walls. However, these walls act as sound barriers and provide privacy and separation inside a home. Additionally, interior walls act as insulators and sometimes provide additional fire protection.


The Difference Between Drywall and Plaster

When it comes to the walls inside a home, two of the most common types of wall materials are drywall and plaster. The use of plaster dates back to the ancient Egyptian times, as it was often used for tombs. As technology advanced with time, drywall became more durable and available for use. Drywall has a evolved through its history. By the 1950s, drywall spiked in popularity as a material optimal for interior walls, and today the product covers a large majority of the walls inside most modern homes. Let’s take a deeper look at the two types of material.



The most common form of plaster for interior walls is known as gypsum plaster. One of the main benefits of this material is its durability — which is why many ancient Egyptian tombs made of plaster are still standing today. There isn’t much that can bring plaster down. Plus, it produces a high-end finish that is aesthetically pleasing and easy to paint. On the down side, plaster walls require a lot of time for installation. Plaster walls are generally created through a three coat process and often require a certain amount of skill and experience for proper application.



Drywall has become an easy commodity and an efficient way to build a home. Manufactured in factories, drywall sheets are very thin, strong boards made out of gypsum sheets. Installing drywall is a fairly quick process compared to that of plastering. The boards are cut to fit the shape of the walls. These boards are then nailed to the wood framing of a home. Then, the installer will use a joint compound to fill in cracks between separate boards of drywall and to essentially glue the board to the floor and ceiling. Drywall can last decades if it is not damaged through the years. While it’s a great product, if enough force is applied it can easily crack or get holes in the surface. However, it is quick and simple to repair most of the time.


As you can see, both drywall and plaster have their own unique set of advantages. We hope this clears up any misunderstandings or curiosities as to what differences there are between drywall and plaster for interior walls.

You might not think that drywall has a variety of available textures and styles, but it certainly does. Generally, drywall texture styles can be grouped into two categories. Their method of application for each type or style determines what group they are in — some textures are applied manually with basic hand tools, often referred to as hand applied drywall textures. The other category is referred to as sprayer applied drywall textures, which require a texture machine.

At American Spray Technologies, we specialize in drywall texture spraying equipment. In this post, we are going to take a closer look at each category and some of the most popular styles and textures in each.


Drywall Textures Applied By Hand

Drywall textures that are applied by hand can be as unique as the applicator is creative. A pan and knife are the most common tools used to apply hand textures. Some textures are applied with special brushes to swirl or stomp patterns in the material. Paint rollers or paint sprayers are even used sometimes. With this technique, knives, brushes, or rollers are then used to create unique patterns and styles


The textures applied by hand can vary depending on the technique used and skill level. Even when using similar techniques, different applicators will likely produce different texture styles.


Common Types of Hand Applied Drywall Textures

  • Smooth wall
  • Rosebud stomp
  • Swirl
  • Hawk and Trowel


Drywall Textures Applied By A Drywall Spray Rig

Drywall spray texturing on walls or ceilings certainly adds class to an ordinary room. While not all appreciate this textured effect, there is more to it than aesthetics. Soundproofing, as well as hiding painting and drywall installation mistakes, are among some of the benefits associated with this application method. There are a variety of drywall spray rigs available on the market. They typically have a tank or hopper for the drywall mud, a compressor for delivering air to atomize the material, a hose, and a gun to spray the material. Larger spray rigs are fitted with gas or diesel powered motors that run the material pump and the air compressor for powerful and efficient application. Smaller drywall texture pumps may be air driven diaphragm pumps or rotor/stator pumps driven by an electric motor. 

Drywall mud is pumped through the hose to the gun. The gun is fitted with switches and valves that turn the pump on and off and control air volume. Using drywall mud and compressed air, the gun sprays the material onto the drywall surface to create a texture. The type of texture depends on the type of material used, the size of the nozzle on the texture gun, and the amount of compressed air that is mixed with the drywall mud.


Common Types of Sprayer Applied Drywall Textures


  • Popcorn
  • Knockdown
  • Orange peel

As you can see, the application methods have their differences. When it comes to matching drywall textures, it is often difficult to do. Check out some tips for matching drywall texture.

When installing drywall, there are some issues that can crop up, regardless of your experience level. Today, we’re going to look at four common drywall problems, as well as how to solve them. At American Spray Technologies, we specialize in drywall spray rigs that can be customized to fit your exact needs. Give us a call to get started building your rig today!



Sometimes a drywaller can get overzealous, sanding the mud compound and joints too much. When this happens, you can sand into the drywall paper or fiberglass tape that covers the seams. This can even extend to the surface of the surrounding drywall, compromising the integrity of the whole installation.



An easy way to check your progress while sanding is to place a light at a low angle, pointing up to the wall. This will make it easier to see uneven surfaces like rises or bumps, acting as a guide for where to sand and where to stop.


Screw Pops


When screws or nails are driven into the drywall too deep, they break the surface of the drywall paper. This heavily decreases the holding power of the screw or nail.



To avoid this, drive the screw exactly to the surface of the paper cover. After that, give it a quarter or half-turn to push it just slightly below the surface of the paper. There are special drill attachments available to allow you to set the depth of the screw. With a screwgun, there is a clutch that lets you determine the depth of the drive. If you have already pierced the paper, don’t worry about removing it. Instead, put another screw near the one that popped to replace it. You can find more info about screw pops in a recent blog we posted.


Electrical Boxes


Though it comes easier to drywallers with more experience, it can still be difficult to cut a hole in the drywall to line up with an electrical box that has been nailed onto a stud.



One option, though not the best, is to cover the electrical box with lipstick or some other marker, then imprint it on the drywall to show where to cut. Another option is to mark the spot with painter’s tape, install the drywall, then cut the hole. A third option exists, but it requires a tool called a Blind Mark, which allows you to make an outline for the cut with magnetic pieces, often resulting in perfect holes.


Tight Drywall Joints


If the joints connecting two sheets of drywall are too close together, you risk breaking the drywall. It’s also important to leave room for the natural expansion and contraction of the frame. If the joints are too tight, seasonal expansion can cause drywall to crack.



Although it’s not something that can be fixed retroactively, you can avoid it with a little bit of pre-planning. Use a guide to ensure there is a ⅛” space between drywall sheets. You can use the blade of a drywall square as a guide, but thin strips of wood can also work.


Drywall can be tricky to install and even trickier to master. When you know how to overcome the common problems, you’ll be a drywall guru in no time. If you need a new drywall spray rig to get the job done, call American Spray Technologies today!

Construction sites can be an incredibly dangerous place to be. However, for contractors it’s not an option for them to steer clear of them — it’s basically their office! We recently took at look at drywall safety, but today we’re going to expand our scope and talk about some ways that you can make your jobsite safer for everyone around. We all have work to get done, so there’s no reason to needlessly endanger ourselves as we do it. With some safety ground rules in place, everyone can go home at the end of the day without issue. If you’re a professional contractor looking for the equipment to get the job done, check out American Spray Technologies’ line of drywall spray rigs.


Entering and Exiting Equipment

One of the most common causes of injury on a construction site, surprisingly enough, happens when equipment operators are entering or exiting their equipment. Luckily there are ways you can lower the risk of workers getting hurt, such as: Checking boots and gloves for mud or other slippery substances and wiping them off. Using a hand or foot hold before pulling yourself up. Using a step ladder if necessary to facilitate the safe entrance and exit of the equipment. Asking someone for help up. There’s nothing to be ashamed of if you need help to be safe. Don’t try jumping onto or off of equipment. Take your time getting on or off equipment.


Personal Protective Equipment

Just like athletes have equipment designed to keep them safe when they play, construction workers have their personal protective equipment. In order to stay safe while on the jobsite, you need to dress for the job. If you’re going to be lifting heavy objects, it’s important to protect your back with a back brace. Any time you’re using dangerous tools, gloves and safety glasses are a must. When working on scaffolding or ladders, a safety harness can help you avert disaster. When working in slippery conditions, non-skid, rubber footwear is vital to keeping you on your feet. Since you want to be sure-footed when lifting heavy objects, these types of boots are quite helpful in those situations as well. Construction work has you on your feet for hours at a time, so it’s important that you find the most comfortable composite-toe shoes for work. You will also want to wear a breathing mask if you’re working in an environment with a lot of dust, debris, or dangerous toxins. For the safety of the whole jobsite, first aid kits and fire extinguishers should be close at hand and easy to access.


Safe Loading and Unloading Equipment

Whenever you’re dealing with heavy machinery, there is the danger that equipment could roll over while you’re loading or unloading it. This makes it important for you to ensure the ramps you’re using are straight and clear of obstructions. Workers need to keep a safe distance between themselves and the equipment in the event of an emergency. When loading or unloading equipment, someone should act as a spotter to ensure it is guided properly and clear of the ramp before turning. The trailer deck and workers should have plenty of clearance prior to loading the equipment. Once it is loaded, proper tie-down procedures must be implemented.


Climbing Hazards

Workers that are climbing ladders or stairs regularly for a project should take special precautions to stay safe. Ladders and stairs should be inspected anytime they’re going to be used, with special attention paid to find any damaged, loose, worn, weak, or broken spots. If, at any point, this damage is found, those areas should be avoided and the foreman needs to be notified. Ladders and stairs should be kept clean, dry, and free of clutter. When working in rainy or wet conditions, metal ladders should not be used. When it’s an option, aerial lifts and elevated platforms are safer than balancing on a ladder.


Crowded Areas

Few things can get as frustrating as a crowded work area, and this is especially true when it comes to heavy machinery. While people might enjoy watching large equipment at work, it’s an unnecessary risk to take. At any point large machinery is in use, people on the ground should keep a safe distance away. The foreman needs to enforce this policy and review it regularly at safety meetings to ensure everyone is on the same page.


A safe jobsite allows us to get our work done effectively and without issue. Keep these safety tips in mind so you can steer clear of accidents.

One of the easiest mistakes contractors and do-it-yourselfers can run into when working on a project is sticking to the same joint compound no matter what the job is. However, depending on the project you’re working on, your joint compound of choice might not be the best one for the job. Today, we’re going to take a look at the different types of joint compounds and which jobs they are best used for. 


Pre-Mixed Compounds

Pre-mixed compounds are typically air-drying, which allows you enough time to work the compound while taking longer for it to finish drying. This makes them ideal for projects that focus on a whole room, or for jobs that require more time to finish getting all the pieces into place. While it may require you to dilute it slightly with some water, pre-mixed compounds can be stored in a plastic bucket for extended periods of time without decreasing the quality of the compound. Some contractors will cover the container of a partially-used compound with some plastic to retain the moisture levels they’re looking for.



As you can tell by the name, all-purpose joint compound can be used for just about every part of the finishing process. However, while it can get the job done, that doesn’t mean that it is actually the best compound for every job. This is a good option as a texturing compound, as it has an extended dry time which allows you to manipulate and adjust it to your liking.



Lightweight compounds aren’t as dense or heavy as other finishing compounds. This makes it a good choice for a finishing coat thanks to how easy it is to sand down. That being said, some drywall contractors will forgo lightweight compounds, as they believe it doesn’t contain as many adhesive agents within it.



Pre-mixed taping compounds are developed specifically for the taping portion of the finishing steps. A problem found with all-purpose compounds is cracking when undergoing the taping process. Taping compound ensures the tape stays in place and shapes well with a knife with minimal cracking issues.



A thinner mix than other compounds, topping contains fewer adhesives within its mix, which makes it a bad choice for taping. It is very white, easy to sand, and has a very fine texture. The thin consistency makes it a great option for adding texture to a wall.


Ready-to-Mix Compounds

Powdered compounds that are ready-to-mix often set faster, harder, and are quite tough to sand. Because they set so quickly, these compounds are ideal for repairs, fast-track jobs, and professionals that move efficiently on a job site. As these compounds set, they release heat, leading to them being commonly referred to as “hot set”. Prior to mixing, it’s incredibly important for the compound to be kept dry and sealed in plastic. Any water or excess humidity can cause the chemical reaction that sets the compound to begin, which will ruin the entirety of the contents.


Hot or Quick-Set

Considered the professional’s standard for joint compounds, hot set is the original ready-to-mix compound. Setting quickly and remaining harder than other compound options, this compound is sturdier on a job site and is exceptionally resistant to scrapes. Sets even faster than normal in warm or dry conditions and it is the most difficult compound to sand.



While it shares many similarities to hot set compound, easy-sand is a good option if you’re not sure if you’ll be able to get back to a joint to finish sanding it fast enough. Consider this a good insurance option if you don’t know if your sanders will be able to keep pace with the rest of your crew.


Choosing the right joint compound depends on a variety of factors, including the type of job, conditions of the area, skill level, and desired effect. Take all of these factors into consideration to ensure you choose the right joint compound for whatever job you’re taking on.

With OSHA issuing a final rule regarding workers’ exposure to respirable crystalline silica, it’s important to ensure you’re taking proper steps so your project site is safe for everyone. Respirable crystalline silica is present in many construction materials, such as concrete, brick, mortar, granite, and sand, which means just about everyone involved can come into contact with it. Research has shown that prolonged and excessive exposure to crystalline silica — which is kicked up into the air when workers chip, cut, drill, or grind objects that contain it — increases many health risks, including silicosis and other respiratory illnesses.


Since keeping workers safe is vital, American Spray Technologies has put together five important things to know about the new silica dust regulations and how to mitigate the hazards it presents. 


Written Respirator Program

OSHA requires a written respiratory program to comply with this new standard. Per OSHA Respirable Crystalline Silica in Construction Regulation – 29 CFR 1926.1153, all respiratory protection programs must include detailed, written, and worksite-specific procedures for many situations, including:

  • Assessment of exposure to identify any airborne hazards that are present.
  • Selection of respirators based on which hazards have been identified.
  • Medical evaluations of workers to validate workers are able to safely wear selected respirators.
  • Any use of respirators.
  • Proper maintenance, cleaning, and storage of all respirators.
  • Verifying air quality levels if using respirators with air supplies.
  • Training and fit testing of workers.
  • Evaluation of respirator program.


Respiratory Program Administrator

After creating a written respirator program, an administrator needs to oversee its implementation at the job site. They will be in charge of evaluating all elements of the program regularly, ensuring their proper implementation. All records, tests, and inspection reports must be kept up-to-date. Any respirators that are used need to be evaluated to ensure they are still in proper condition to be used for the conditions present at the construction site. All of these elements must be recorded in detail, including evaluation notes, issues that have been found, and any corrective measures that have been taken.


The administrator should watch and speak with anyone using a respirator to make sure they are using it properly, they understand how to use and maintain it, and that the respirator is working as intended. For silica work sites, the program administrator can also be the silica competent person that the silica regulations require. It is not necessarily required for this person to occupy both roles, but it can make the administration and evaluation of the program easier.


Medical Evaluation

It is required by OSHA for employers to provide a respirator medical evaluation to any workers before they are able to wear a respirator. This evaluation will usually include a questionnaire asking about medical conditions, workplace conditions and hazards that may affect a worker’s ability to wear a respirator safely. Once this questionnaire is completed, a licensed healthcare professional will evaluate the responses and determine if the worker is medically fit to wear the class of respirator in question. An employer will be required to reevaluate a worker’s ability to wear a respirator safely in the event of:

  • Any signs or symptoms that can affect a worker’s ability to use a respirator safely.
  • A physician, supervisor, or the respiratory program administrator asks for a reevaluation.
  • Fit testing or program evaluation indicate a reevaluation is needed.
  • Any changes to workplace conditions that put increased burden on a worker, such as changes in temperatures, level of exertion required, or any equipment needs.


Fit Testing Respirators

Tight-fitting facepiece respirators are available in two styles — negative pressure (elastomeric and disposable) and positive pressure (powered air and supplied air). All of these respirators have to be fit tested to make sure there is a good seal between the user’s face and the respirator. There are two basic types of fit testing allowed by OSHA currently, Qualitative (which gives a pass/fail result) or Quantitative (which provides a numerical result).

While either fit testing method can be used for most types of respirator, full-face negative pressure respirators must be fit tested using quantitative methods. Respirator fit testing is to be repeated on an annual basis at a minimum, if the user changes the make or model of respirator, or if the user has any physical changes that would affect fit, such as significant weight gain or dental work.


Where to Learn More

While this blog post is a brief and general overview of proper respirator use, it is important for all employers and employees to familiarize themselves with the full regulations put in place by OSHA (29 CFR 1910.134). You can also learn more about beginning a respiratory program with this handy guide from 3M.

No matter what the job is, it’s important to make sure the site is safe for everyone involved. While it may seem like it’s not a big deal, drywall safety is imperative to ensure all the workers get to go home at the end of the day without any injuries. Even beyond just a construction crew, many people will be around the project site, including customers, inspectors, architects, and other trade and service professionals. For that reason, we have gathered some information about safely handling, storing, and installing drywall.


Not Everyone Knows What You Know

When visitors arrive to a project site, you shouldn’t make the assumption that they understand the hazards surrounding them or how to be safe in a construction area. Even with experienced tradesman, they may not be as familiar with storing or handling drywall as you are. While you know that pulling a stack of drywall forward is dangerous, they may not, and disaster could follow. To help avoid these types of situations, it is important that any vertical stacks of drywall are properly secured. Not only will this prevent people who don’t understand the weight and danger drywall presents from getting hurt from pulling it forward, it will also avoid an issue where the stack becomes unstable due to other work going on at the site. Most of this misunderstanding comes from people underestimating how much drywall actually weighs.


The Weight

Many people have some sort of disconnection between what they think drywall weighs and what it really weighs. Think of it this way — a stack of ten sheets of drywall on the floor would be pretty impossible to lift all at once, whereas you can easily pull a sheet forward when it’s standing vertical. However, that ease ends up belying its true weight. A stack of drywall can weigh around a thousand pounds, and if it’s tipped over, it will gain momentum. That means by the time it reaches the floor, it will have a force equivalent of six thousand pounds. It’s pretty easy to see how that would be a dangerous situation. While there are many benefits of stacking drywall vertically, the dangers are something that need to be considered as well. But it is not as simple as just keeping sheets laying flat on the floor, unfortunately. The repetitive motion and strain of bending over and lifting up a sheet of drywall over the course of a project will wreak havoc on an installers back. You can avoid that unnecessary strain and pain by securing a vertical stack, along with placing a warning label on each stack to help everyone understand the precautions they need to take when dealing with drywall.


The Dangers

A construction site will carry the possibility of danger regardless of precautions that you take. It is unfortunately just a part of the job. The weight of a stack of drywall falling on someone is enough to cause severe injury, if not death. Contractors have a responsibility to make a job site as safe as possible, because it’s hazardous enough to be working with heavy materials and power tools as is, without poor planning adding to the danger. All it takes is one mistake or accident to endanger someone, so utilizing safe practices can avoid trouble and tragedy.



With the danger involved in all aspects of construction, it stands to reason that OSHA has rules and regulations in place to keep everyone safe. One such regulation is the requirement that all edge stacked drywall must be properly secured. This regulation covers gypsum board, plywood, trusses, and any other similar materials, stating that they cannot be stacked on their edge unless they have been totally secured against falling or tipping. Not following these regulations can result in a citation or penalty from an OSHA inspector. That means that breaking these rules doesn’t just put people in danger, it can also cost you or your company money, even if no one gets hurt. It’s just not worth skipping these precautions, no matter how you look at it. It’s a good idea to review all of the requirements put in place by OSHA, as different states may have different regulations to follow.


Ensure everyone working on the job is intimately aware of the best safety practices to avoid accidents. This is the only way to make sure everyone gets to go home at the end of the day happy and healthy. No matter if it is a residential or commercial job site, drywall accidents can affect anyone and everyone involved — from small children visiting their new home, to experienced contractors, to the elderly. This makes it imperative for everyone on site to not only understand the dangers present, but to take the precautions to warn and protect anyone that may be on the property. All it takes is a little extra time to make sure a stack is correctly secured and has a warning label on it to make the site a bit more safe for everyone.

When you’re patching drywall, matching an existing texture can be pretty difficult. Many variables come into play that can cause the new drywall patch to be visually different from the drywall that surrounds it. With that in mind, we have gathered five tips to help you make a more seamless patch with a matching texture. If you’re looking for a drywall spray rig customized to fit your exact needs, American Spray Technologies has what you are searching for.

Use the same thickness of drywall

This is the first and possibly most important tip. If you use a different thickness than the existing drywall, it stands to reason that it wouldn’t match up correctly. Before you get started, measure the thickness of the existing texture and use the same drywall size for your patch. For example, if the wall was hung with ½ inch drywall, you should use ½ inch drywall for your patch.

While this process is pretty easy when dealing with drywall that was hung directly to the studs or other backing, patching plaster walls gets a bit more complicated. That is because plaster may not be an exact measurement that is easily matched. To compensate for this, you may need to use thin wooden shims or thick paper that has been folded to match the thickness of the existing plaster walls, which you will then put your drywall patch over so that the wall is level with the patch.

Coat the minimum amount necessary of the existing texture

After installing drywall to your patch, you will need to tape and coat it so that it will blend into surrounding surface. You will need to apply mud to the existing texture that immediately surrounds your patch to ensure the patch is flat with the existing surface texture. When doing this, use the smallest amount necessary to coat the existing texture.

However, that does not mean we recommend sacrificing a flat transition to minimize the amount of coating you use. You may need to coat a wider area to ensure that both levels blend as flat as possible. It’s important to remember: the less you need to retexture, the easier it will be to control your new texture. That means you have a better shot at making both textures match.

Remove lines between the patch and existing texture

As you coat your drywall patch, a line will typically appear between the edge of your patch and the existing texture. If you are coating a smooth surface, you would be able to feather this line (or lap-mark) out so the new coating seamlessly blends into the smooth surrounding area. However, if the surface you’re coating is textured, it won’t be possible to feather it out completely. That is because drywall mud will get trapped in the crevices of the texture, creating an uneven and undesirable appearance.

When you have finished your final coat on your drywall patch, and before you texture it, it’s important to scrape the excess mud away from the existing texture where it has become trapped. Doing this at the edge of where your patch meets the existing texture will help make for a more seamless appearance. There are several different methods you can employ to do this. The first method utilizes a drywall knife to remove the drywall mud. It is removed from specific areas to ensure the seam between the patch and existing area is as random as possible. However, that method can be quite tedious. Others find more success when they use a slightly damp soft bristle brush to rub along the line between old and new.

Whichever method you decide to use, your end goal is to make the line between the existing drywall and your patch look like a random transition. It is important to avoid an immediate or harsh transition between your smooth new drywall patch and the texture that surrounds it.

Utilize the same methods and tools that were used to make the original texture

Though it may seem obvious, the best way to match an existing texture is to utilize the same tools and methods used to make it originally. For instance, if you are trying to match a stomp knockdown texture, it is typically pretty easy, as there are only a few types of stomp brushes that are used. When you look at the pattern in the stomp, you should be able to notice if it was done with a round rosebud style stomp brush or an oblong crow’s foot stomp brush.

If the texture you are trying to match was done by hand, it can be more difficult to tell which tools or methods were originally used. Hand drywall textures can vary quite a bit depending on region and the tradesman’s individual style. Even if you can see the texture was applied using a hawk and trowel, matching the technique is still difficult due to how unique a hand texture is to the individual that applied it.

Sprayed textures like splatter knockdown or popcorn texture are more easily identifiable, as you can tell if it was applied with a spray rig or a hopper. However, it is still tough to determine the exact air pressure that was used or how much force was used to pump the mud through the hose originally. It can even be tough to determine which size spray nozzle was used. Due to the number of variables at play with spray textures, they are the most difficult to match. This means it is critical you match those variables as they relate to the original texture as closely as possible so as to make a smooth texture.

Newer tradesmen may find it is difficult to tell the difference between different techniques that were utilized because that knowledge comes with experience. If you are new to the world of drywall, try experimenting with different tools and methods to learn what changes in technique result in different styles.

Use the same consistency of drywall mud as the original texture

After you have taken the other tips into consideration, using the same consistency of drywall mud is one of the most important factors to be aware of when matching a drywall texture. It is so important because the viscosity of the drywall mud can make or break your patch. Even if you followed the previous tips, a mud that is too thin or thick will make your patch less smooth and more obvious. The last thing you want is a patch that clearly sticks out, apart from the rest of the wall.

This is tough to handle, as much of matching the exact consistency comes down to making an educated guess. The only real way to get a feel of how to match mud consistency is through experience. Mixing different types of texture mud and applying different texture styles is the best way for a tradesman to get the experience necessary to make that guess. However, with that experience, you will be able to look at a type of texture and make a strong estimation as to how thick or thin the mud was when it was originally applied.

When you’re learning how to match drywall texture, it’s important that you take your time with this step. Start off by applying the texture to a small area and examine it closely. As you examine it, try to imagine what it will look like after it has dried. Let it set for a few minutes, but don’t let it dry out entirely as textures may look different while they dry. If it doesn’t seem like this texture is matching perfectly, remove the texture you just applied, add some water, and try again. Once you believe you have matched the consistency, you’re ready to texture the whole patch.

Matching an existing drywall texture can be difficult, but it is possible with practice and experience. Follow our tips and we think you’ll have a much easier time with applying your patch.
