How Do You Waterproof A Tiled Tub Surround?
Once the tiles are in place on a tub surround, the next step is to waterproof the area to ensure water does not seep behind the tub. Waterproofing is critical to the longevity of your new tub surround and can not be overlooked. After the tile has been set, wait overnight to allow it to cure before removing the tile spacers. Wherever the mortar in the joints is less than 1/4-inch below the tile surface, dig it out with a grout saw, a small screwdriver or a utility knife. Clean all the mortar off the surface of the tiles using a damp cloth or a pot-scrubbing pad. Mix up a batch of latex-reinforced grout in a bucket. Scoop some grout out of the bucket with a laminated grout float and put the grout into the lines between the tiles with the float held nearly flat. Move the float in at least two directions at every point to ensure that the grout is pushed in completely.
