Ahead, we’ll take you through a step by step guide to what is entailed with concrete polishing service. With the use of different levels of grit, you can choose custom levels of polish and smoothness to suit your style and needs.
First, the concrete is prepared by grinding the surface. Any previously applied concrete coatings must be removed before the procedure can begin.
If the concrete has become victim to any cracks in the surface, epoxy resin or other types of fillers shall be used to seal the cracks.
Once the concrete has been sealed, a special machine using a type of diamond particles of different metal bonded grits, depending on the desired outcome of the polishing, is used to grind down the surface. Usually, the procedure will start with a grit of 30 to 40, followed by 80, and then finished off with a grit of 150.
Once the grinding has been completed, a chemical hardener will be applied to densify the surface.
A new resin-bonded diamond disc is used at this point with a grit ranging between 100 and 200, or even a combination of both.
Polishing is then performed by a 400-grit resin-bonded diamond disc, and then an 800 grit disc.
The final polishing will be performed with the use of either a 1500-grit or a 3000-grit disc for a mirror-like finish.
A coat of stain guard used over the newly polished concrete surface is recommended.
