How Do You Level Concrete For Tile Installation?
How flat a concrete slab needs to be depends on the sheen of the tile finish, the size of the individual tiles and your personal standards. Filling an occasional low spot in a slab is a simple task. If the slab is just plain rough or irregular, however, you should call in a professional slab finisher. A professional slab finisher can apply a skim coat of new concrete to make the floor perfectly smooth so you can get the results you want when you install the tile. Locate and mark the deepest points of all the hollows and valleys in the slab. Use a straightedge that is at least 4-feet long. Mark the perimeter of each hollow by swinging the straightedge around the deep points. Make a mark at each perimeter point and then connect the markings to draw a circle that fully contains the hollow. Clean the slab by sweeping away all dust. Make sure there is no oil or wax on the concrete slab. Use a brush to apply the latex primer to the hollows. Cover the entire area of the hollow. Pour self-leve
