Spraying On American Clay

 

American Clay Earth Plasters can be sprayed through various texture spray systems. Rotor pumps, rotor/stator pumps and diaphragm pumps have all produced good results. Material consistency varies with the system and the length of the hose being used. Spraying saves a significant amount of time and labor during application but more prep time is required to protect adjacent surfaces.

Recommended System

 

  • Benron texture sprayer for interior and exterior finishes

  • Model Rotortex 245E Pro

  • 3/8" (8-10 mm) fan tip for Forté Base, Forté Finish, Forté White, Loma, Porcelina, or Lomalina applications

  • 1/2" (12 mm) cone tip for Enjarre or Marittimo applications

  • Air pressure: 45-55 PSI at tip (3.16-3.86 kilogram-force/square centimeter)

  • Air volume: 16-22 cubic feet per minute (0.45-0.62 cubic meters per minute)

General Guidelines

 

  1. In general, the technique is the same, whether you are using a hawk and trowel or a spray system to apply the plaster.

  2. Follow general application instructions and prepare your substrate properly.

  3. The major differences of spray applications include the plaster being mixed to the consistency needed — usually quite loose or wet — and poured into the hopper.

  4. For systems other than the one above, the average tip size has been 8 mm. Larger tips can be used based on the material pump rate.

  5. The plaster should be sprayed evenly across the surface and immediately troweled to a consistent thickness. We recommend at least one person spraying the material on the surface with one or more persons back troweling the plaster.

 

Keep in mind, plaster spray application is different than drywall texture spray application. Plaster spraying utilizes roughly 110% coverage whereas a typical drywall knockdown texture utilizes around 80% coverage during the spray application.
