How to Faux Finish Concrete Floors

Use a sturdy broom to remove large debris. Vacuum the floor thoroughly. Use a clean, damp cloth to remove particles such as dust. Do not forget to clean all cracks and crevices.

Dampen floor and apply a degreaser to the entire surface. Allow it to sit for as long as the manufacturer recommends. Rinse the floor and allow it to dry.

Fill all cracks with a concrete crack repair product. Sand it flush with floor. Remove any remaining debris.

Apply an even coat of good quality primer to the entire floor. Allow it to dry completely.

Use stencils, stamps or freehand designs onto the floor. For faux marble, apply the darkest paint. Layer and swirl each lighter shade until you achieve the desired results.

Use a ruler and painter's tape to mark geometric and other sharp-lined designs. Peel the tape off once the paint has dried.

Apply a thin layer of polyurethane to the floor. Allow this to dry. Lightly sand the floor with a fine grit paper. Clean dust away with water dampened cloth and allow it to dry. Apply a few more coats of polyurethane remembering to sand lightly between each one. Do not sand the final coat. Allow the floor to dry completely before walking on it.

Apply a thin layer of good quality floor wax, if desired. Every two to three years or when required, lightly sand the floor and reseal with polyurethane.
