AST texture machines are known for their rugged trailer construction and compact size that make them easy to tow, reducing wear and tear on your vehicle. Our proven hydraulic control system provides infinite control of mixing and pump speeds. Speed control is very important to get the quality drywall texture results that you expect from your spray machine. All AST trailers also comes with electric brakes as a standard trailer feature.

AST drywall texture rigs are optionally equipped with a new state of the art cast pump housing that includes special Max Seals and a Butterfly Valve and Star Drive connecting rod. Max Seals provide protection for the hydraulic motor, the butterfly valve shuts off the flow of texture from the pump and the Star Drive connecting rod lasts up to four times as long as standard square drive parts. Because of these unique design features you will no longer dread servicing your pump because of worries over a big mess. With a turn of the valve the flow of mud from the texture sprayer tank to the pump body is shut off, allowing the rotor and stator to be removed without leaking material on the ground. That saves you time – every time! Video: HD Pump

The cost of financing a drywall texture sprayer is so low that it takes you only a few jobs per month to pay for the investment in your new spray equipment. Learn about financing on our financing page.

We are tickled pink with (our texture machine)'s unbelievable, so easy to use and much more consistent than our last machine. It has cut my time down at least 30%! My guys fight over who is going to get to spray with the rig.

- Ron Nolan w/Rodriguez Drywall

With over 25 years of spraying, this rig gives me a new and exciting spraying experience, the quality and ease of spraying makes working enjoyable again.

- Pat Hallet w/ Pat's Drywall

I love of the rig. The platform is twice as big as other rigs. I really enjoy the flex gun and texture strainer. The paint job is superior and the low profile makes it a great rig for towing and going around corners. When it's time for a new rig, it will be another American Spray without a doubt.

- Robert Hammond w/IDS

Best piece of equipment I have ever owned.
