Like glass tiles, you will not need to seal most porcelain tiles, particularly if the porcelain is already glazed. It depends on quality. Porcelain is very water resistant, but it is not 100% waterproof. To avoid staining, some homeowners use a penetrating sealer. It is also a good idea to seal your grout. Unless you use epoxy grout, grout is very porous and can harbor bacteria, mold, and mildew.

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.

Replacing tile flooring can take a few days for a pro, but larger rooms will need more time. It takes eight to 12 hours for a tiling pro to remove old grout and tiles across 100 square feet. Then, it will take about four hours to prep the subfloor for tiles and another eight to 10 hours for a pro to install new tiles. Your tiling project may take up to a week, depending on the size of the room.

If you’re handling your tile removal yourself, seal the room using painter’s tape and heavy-duty contractor bags to prevent dust and shards from escaping. Use a claw hammer or a pry bar and a mallet to get behind the tile and pry it away from the floor or wall. Once your tiles are all removed, sweep everything into contractor bags for disposal, being careful not to overfill them. Make sure you wear a dust mask, safety goggles, and work gloves to keep yourself safe from injury while you work.
