Craftsmen Specification 2 - Pneumatic Spray Uses material sprayers to uniformly apply small aggregates , silica , and / or sand to the surface of plastic concrete . The industry-wide method of hand broadcasting materials leaves patterns on the surface finish . Material sprayers apply materials by overlapping , offering a more uniform seeding of materials . Additional patents and patents pending also allow us to blend “ wet materials ” to create uniform surfaces on stairs , walls , and horizontally placed concrete to eliminate common problems that occur using dry-shake material and color hardeners that rely on bleed-water to activate the cement such as blistering .
