MatchCrete (tm) Clear Concrete Repair Polyurethane can be used to repair concrete that has an irregular tint or has been stamped. Remove any debris, loose concrete, repair materials, or caulk that has failed. Cut the fissure open slightly with a diamond blade and clear away any loose concrete or debris. Mask the crack with tape. Pour Repair Material into the crack and smooth out with your finger. Let it cure for at least 24 hours and then seal the area with MatchCrete. If you want to fill in a stamped concrete floor, use a fine-grained sand and cement mixture. For a darker look, add colored pigment or crushed stone. Make sure the material is clean; otherwise, it will show up when you wash the floor. Allow the mixture to dry completely before walking on it. Stamped concrete is easy to maintain and durable. It can also add style to your home exterior. Use a tool called a stamping machine to create custom designs in your stamped concrete. The design must be printed on a rubber stamp and pressed into the wet concrete. The best way to care for your stamped concrete floor is with a mild soap and water solution. Scrub the surface to remove dirt and stains; rinse well after cleaning. You may need to re-stamp the floor once it has dried out.
