Both resilient sheet flooring and resilient tile require a smooth surface for proper adhesive bonding. You
can repair an irregular surface with an embossing leveler or a masonry leveling compound. When the
surface is dry, spread adhesive with a notched trowel, following the adhesive manufacturers instructions.
Lay the tile so joints don’t coincide with the joints in the underlayment.

Seamless flooring, consisting of resin chips combined with a urethane binder, can be applied over any
stable base, including old floor tile. Apply this liquid in several coats, allowing each coat to dry. A
complete application may take several days, depending on the brand. You can repair a seamless floor
by applying another coat. Damaged spots are easy to patch by adding more chips and binder.

Cork Tile
Cork is a natural sound absorber and insulator. It is quiet underfoot, and can last for decades when
properly maintained. Cork will expand and contract based on humidity, although to a lesser degree than
wood. Cork tiles should be given time to acclimate to the environment before installation. Remove tiles
from their packaging and store them in the room where they will be installed for at least 48 hours prior to
installation.

Most manufacturers recommend using a water-based contact cement adhesive for cork installation.
Cork is porous, allowing the water in the adhesive to evaporate and create a strong bond. It’s a good
idea to test for proper adhesion before proceeding with the installation. Excessive moisture can damage
cork flooring. For kitchen, bathroom or other high-risk applications, follow the manufacturer’s guidelines
for sealing cork floors with urethane or floor wax.

Granite and Marble Tile
Common granite and marble surface finishes include polished, honed, and flamed. A polished surface is
highly reflective, and is best suited for low-traffic areas. A honed surface has a duller, more slip-resistant
finish that’s less likely to show scratches. Flamed tiles have a deeply textured surface that’s useful for
applications requiring additional slip-resistance.

Marble is softer and more porous than granite, so it’s more susceptible to scratches, but it can be
repolished when necessary. Marble is also susceptible to damage from alcohols, oils and acids
commonly found in the home. A penetrative sealer is generally recommended when installing marble in
high-risk areas such as kitchens and bathrooms.
