Stonecoat for small or detailed areas, is best sprayed from a Hopper Gun, gravity fed and launched by the compressed air onto the work surface. The aperture of the spray system significantly effects the outcome. Too small an opening will exclude stone and cause for more resin and Nozzle blocking will continuously occur. Too large an opening and a splatter will occur forming blobs on the work. However the application time is greatly improved as such a BALANCE must be maintained between quality flat finish and speed of application and best coverage rates. Depending on the hopper gun design 100 psi is a good starting pressure, Too high a pressure and the surface will be undulated by the air pressure and excessive bounce back of stone. Too little and the stone will not propel to the surface evenly or develop the membrane. Stonecoat is sprayed from approximately 400 mm from the surface and experimentation will quickly result in optimum distance. Too far and excessive resin lose and bounce back of stone is obvious, too close and a thick uncured matrix is deformed by the air pressure.

Stonecoat will bond substantially to almost any substrate including metal castings, painted sheet metal, timber and manufactured boards, masonry panels and castings and foam boards. Particularly suited to lost formwork systems, as STONECOAT shrinks onto the surface for a tight bound adhesion. Gloss surfaces and plastic plumbing accept STONECOAT and this can allow for plumbing to be installed connected and coated with the wall surface application.
