Uniform spacing between tiles is important for a professional and clean appearance. To achieve this spacing, tile spacers should be placed between the tiles and left in place until the mortar hardens and the tiles are secure. You can use X-shaped spacers vertically in between the tiles and laid flat at the corners.

No, you don’t need to remove the old grout before installing new tile over existing tile. In fact, the old grout helps fill in gaps between tiles, creating a more even surface for the new layer. However, it's important to ensure that the grout is clean, solid, and free of cracks or crumbling areas. Damaged grout should be repaired or replaced before proceeding. Cleaning the surface thoroughly and filling any low spots will help the new adhesive bond properly and ensure a smooth, stable installation.

You can technically install tile over tile, but we don’t suggest it. Installing tile over any surface that isn’t a completely flat and prepared subfloor will result in a shoddy overall job, uneven flooring, tiles that don’t adhere, extra weight, gaps, cracks, and room for moisture and dirt to enter. For the best results, only install new tile on a flat, sanded surface like subflooring or concrete that is prepared for tile.

If you have asbestos tile and would rather tile over it than remove it, or if your existing tile is completely flat and bonded tightly to the floor, you may be able to tile over existing tile. But experts recommend thinking twice before you do.

Glazed ceramic tiles don’t need to be sealed because the glazing already offers some protection against moisture. Unglazed ceramic tiles need to be sealed to keep the porous tile safe from moisture and staining. However, both types of tile can benefit from sealing. Sealant can make the tiles easier to keep clean and offer more resistance to water, spills, and stains.
