SYSTEM 5 - PRESTO PNEUMATIC SPRAY™
Lithocrete® Presto Pneumatic Spray™ allows for the perfect application of minerals such as silica carbide or spar to the
surface of concrete. Hand broadcasting of minerals causes an uneven distribution, creating a splotchy looking surface. By
utilizing a pneumatic-powered materials sprayer, even distribution of the material is possible. The resulting finish is very
consistent and natural-looking. By using the pneumatic application, larger modules can be constructed since the materials
can be distributed over a greater distance with consistent coverage when compared to hand broadcasting.
