Concrete floor for surfacing! Using a concrete floor grinder with a diamond grinding pad is often the best choice to smooth rough surfaces and prepare concrete for epoxies or urethane coatings. The grinding pads are impregnated with diamond bits that effortlessly cut into the concrete surface and create an intense scratch pattern. Diamond pads can grind away paint, epoxy, mastic, corrosion, stains, and years of build-up from older concrete floors. Before surface prep, it is important to determine the concrete surface profile (CSP) for the intended coating being applied. CSP is a system of measuring the roughness of a concrete surface. It is a way of measuring concrete texture, and is important when determining what type of surface blast is needed, and which type of surface preparation job is being done. Prior to diamond grinding, joints and cracks are typically filled to prevent moisture and debris from entering. It also makes for a much easier surface to clean, and a seamless, higher quality looking floor. Diamond grinding is also recommended for high traffic areas where surface irregularities occur with prolonged use. CSP guidelines measure grades of concrete roughness from the smoothest CSP1 to the roughest CSP10. Surfaces are grinded to accept the following coatings: CSP1 and CSP2 sealers; CSP2 and CSP3 thin films; CSP3, CSP4 and CSP5 high build coatings; CSP4, CSP5 and CSP6 self-leveling toppings; CSP5, CSP6, CSP7, CSP8 and CSP9 polymer overlays; and CSP5, CSP6, CSP7, CSP8, CSP9 and CSP10 concrete overlays and repair materials. Diamond pads come in various grits, much like sandpaper, so it depends on the type of concrete being surfaced whether grinding is soft or aggressive. Oftentimes, several pads are used in order to achieve the desired results. Lighter grits are used for a rough surface profile result, whereas higher coarser grits are used to achieve a polished surface. A concrete floor grinder is usually moved along the surface in slow arcing motions. Making several passes over the concrete results in creating a smoother surface. Another important piece of equipment used during diamond grinding is a dust collector, which is fairly self-explanatory. It helps keep dust from blowing all over the place. Since diamond grinding significantly smoothes concrete surfaces, it can be used to reduce noise on exterior pavements and interior floors. It also enhances surface texture and skid resistance, removes bumps, and reprofiles the surface, thereby increasing the life of the concrete. It can help cure warped or curled surfaces, improve drainage, and remove ruts from wear to garage floors.
Professional diamond grinders ensure all safety precautions are in place for surface prep and throughout the grinding process. Tools are prepared for either wet surface or dry grinding, hoses are frequently cleaned during the process, dust is managed, wet slurry is maintained, and safety measures are in place for using electrical power equipment in areas where water is present. Diamond grinding is a process that involves skill and practice.
