No, you don’t technically need a cement backer board for a wall tiling project, but not using it risks disastrous moisture damage. Cement is naturally water-resistant, whereas drywall soaks it in, which can lead to warping or mold growth. Always use a backer board treated with a waterproof membrane for bathrooms and other chronically damp areas to ensure complete tile shower waterproofing.

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.

For glass tile, you want to use unsanded grout. Sanded grout is a stronger and grittier cement grout that is great for installing tiles with wider gaps and into joints. However, it is susceptible to scratching glass tile and is more difficult to use in thinner gaps. Unsanded grout, while more expensive, is easier to fit between thin gaps and is less harsh on delicate materials, like glass tile.

While you shouldn’t use thinset mortar on its own as a floor leveler, it can work alongside other products to help level floors. For instance, you could start with a self-leveling compound, let that dry, then apply backer board with thinset mortar to help fully even out the floors ahead of laying tile.
