Cultured marble is a manufactured stone that is cast into shape from a liquid state, like concrete. Cultured marble offers a palette of designed veining and color options. Cultured marble is often used in wet areas of the home for countertops, bathtub surrounds and shower stalls. Once cut to fit, installation of cultured marble consists of gluing the marble in place and allowing the adhesive to dry.

Dampen a clean cloth with rubbing alcohol and wipe the back of the cultured marble to remove all dirt and dust. Allow the marble to dry completely.
Apply 100 percent clear silicone caulk to the back of the cultured marble. Apply the caulk in lines with an “S” shape. Do not place the caulk near the marble’s edges, or it may squeeze out from behind the marble and onto adjacent surfaces.
Position the marble in place and hold it firmly until the caulk has time to set. You can use clamps or straps to secure the marble while the caulk cures.
Caulk the outside edges of the marble with 100 percent silicone caulk in a color that matches the cultured marble. Use the colored caulk to close gaps between the marble and the surface it’s adhered to.
