Two conditions must be met before any coating can achieve a good bond with a concrete floor. First, the surface must be free of dirt, chemicals and other contaminants.
Second, the surface must be given a mechanical etch or profile. Surface profile can be described as miniature ridges and valleys. Without a good profile as a base, the chances of coating becoming chipped or braking up altogether increase significantly, and the life expectancy of the floor is reduced. Over the years several methods have become available.
At Top Gear Epoxy Flooring we use a portable shot blaster for the large areas and a high output angle grinder for corners, edges, bumps and cracks.
These machines connected to a vacuum system make the concrete preparation 99% dustless.
After the mechanical preparation of the substrate is completed we fill any cracks, control joints, holes with a 100% solids, moisture resistant, non-sagging epoxy material to ensure a seamless, uniform surface.
