We determine concrete hardness with a MOHS Concrete Hardness Tester in order to select the correct metal bond diamond abrasives. We test at least 3 areas of the floor to get average test rating.
If the floor is coated, we determine the type of coating and remove with appropriate tooling. Repair and fill any surface holes or cracks. Grind with either 16, 30/40, 70/80 grit metal bond tooling to achieve desired exposure and floor flatness.
We remove metal tooling scratches using 50, 100 or 200 grit transitional tooling. Transitional tooling effectively removes scratches and creates a surface ready for polishing.
Ensure your floor has been vacuumed and all tool marks have been removed. Densify the concrete to help solidify and densify the surface and to provide extra protection from water penetration and staining.
We begin with appropriate resin bond tooling 200, 400, 800, 1500, 3000 grit (3000 grit optional). Ensure dust is removed(vacuumed) in between passes. Burnish floor with 3000 grit burnishing pad after your final grit level.
Once you get the look and polish you’re striving for, We want to protect the surface by applying a commercial stain-guard product and sealer and surface wear protector especially if the surface will be exposed to grease, oil, or chemicals. We use a pump up Sprayer and apply Two thin light coats. We allow coats to dry for at 30 minutes between coats.
