High Luster Concrete Polishing

Gallery Painting specializes in Concrete Polising. Concrete Polishing is a process that is imparting a high luster to a concrete floor depending on the polishing grit. Concrete Polishing grits range from 800, 1500 and 3000 grit. The first determination of the Concrete Polishing process should be made as to what level of sand and rock exposure you want to see as the final polish finished. After that has been made as to the level of aggregate to be exposed, we will execute a plan for obtaining the end result. If the sand level of the aggregate exposure is desired, then we will start with 80 grit metals. If the Rock level of aggregate is exposed, we will start with 16 grit metals to 40 grit metals. If the rock level of the aggregate exposure is desired, we'll select what size rock exposure (1/4" to 1/2") and start with 16 grit metals to 20 grit metals. Any depth beyond the sand and aggregate should be shot blasted to remove the bulk before the diamond grinding process is conducted.

After shot blasting or scarifying, we will start with a medium bond metal diamond with 40 grit to achieve a uniform floor. After the floor is uniform, we'll move up to an 80 grit bonded diamonds and continue the concrete grinding process. The next step would be to hone the floor with a 100 grit resin bonded diamonds. At this point a hardener / densifier should be installed on the surface. Some hardeners may take up to 24 hours to dry and cure.

Gallery Painting will take sufficient care to look closely and examine the floor before moving onto the next grit size. During the grinding and polishing process, there cannot be any scratches from the previous diamonds left behind on the surface as we move up into the finer grits. At 800 grit you will start to see the sheen; after each grit moving up to 1500 grit and 3000 grit.
