Easy to clean and impervious to moisture, tile has always made for a sensible, often stylish flooring material in the bathroom, kitchen, or entryway. Increasingly, those same qualities are even leading homeowners to incorporate tile outdoors, particularly in transitional areas like breezeways and verandas. Here, for the tile to look good and last, it must be laid over a level base. If there are dips and ridges in your slab, you have two options: Rent and labor over a concrete grinder or, much easier, use Rapid Set Concrete Leveler. As the compound spreads, it creates a new, perfectly level surface on top of which you can begin adding tile the same day, if desired, within a matter of hours.
