Length - 03:21 Find Concrete Countertop Supplies Award-winning designer and concrete countertop fabricator Fu-Tung Cheng shows us a simple yet important tool he uses when fabricating countertops—hand-grinding blocks. These hand-grinding diamond pads are great for polishing areas of a concrete counter that cannot be reached by the electric polisher. These pads, like the electric polishing pads, have variations in grit going from 120-grit up to 220-grit, 400-grit, 800-grit, and even 1500-grit. Pads are also used smooth the rough edges of concrete countertops. Be sure that the polishing process done with the hand pads matches that done with the electric polisher. For example, if the polishing is done up to 1500-grit with the electric polisher, then make sure the hand polishing is done in sequence all the way up to 1500-grit. Occasionally, concrete countertop surfaces will be etched by harsh chemicals in kitchens, by wine, or lemon juice that has been sitting on the countertop for several days. In this situation use a little water and these hand-polishing pads to polish out the imperfection. Start this process with a fine grit like the 800-grit pad and polish the spot up to the same polish as the rest of the countertop surface. Sometimes the countertop surface is highly polished and resin pads that are typically used on electric polishers have to be used as hand grinding pads. This is because the hand grinding bocks may not have a fine enough grit.
