Installing Ceramic Tile Flooring � Q&A

Should ceramic tile be waxed?

Glazed ceramic tiles should never be waxed. The purpose of the glaze is to give you a low- maintenance floor, adding a protective layer that would make wax unncessary.

Does ceramic tile need sealer?

Glazed tiles are already stain-proof so there is no need to apply a sealer. You may put a penetrating sealer on your unglazed ceramic and porcelain tiles. The penetrating sealer is an invisible, stain-resistant shield that is absorbed into the surface of the tile. A surface sealer is not recommended because it wears unevenly and you need to constantly touch it up in the high traffic areas.

How long does mortar take to cure?

You should wait at least 24 hours before walking on your new floor. Some installations may take longer, depending on the specifications. Read the labels and talk with your sellers about specific requirements relevant to any products you buy.

What is the most suitable product for outdoor tile installations?

According to international standards, fully vitrified tiles are the most suitable product for outdoor installations. They absorb less than 0.5% moisture and are frost resistant. They can very well withstand extreme climatic variations and remain intact in freeze/thaw conditions.

When and where should backer board be used?

Cement backer boards are thin concrete sheets that are used to cover plywood subfloors. Ceramic and stone tiles are not flexible and require a more rigid substrate than other materials. Cement backer board provides a solid, flat surface to install tiles on if you have a wood subfloor.

Why should I use a waterproofing membrane?

A waterproof membrane stops moisture from seeping through the floors. In areas known for high-moisture, such as laundry rooms, kitchens and a shower floors, a waterproof membrane is recommended over the subfloor (and under the cement backerboard if you are using a backerboard).
