How to Create a Depthless Floor

Sand wood or previously painted floors with a 150-grit sanding sponge or a hand-held, electric floor sander.

Wipe down floors with a damp cloth to remove any dust and sanding particles.

Apply painter's tape to the bottom edges of baseboards where they adjoin the floor.

Brush on a coat of paint primer around the floor's outer perimeter with a clean, angled paintbrush. Apply primer to the remaining floor area with a paint roller. Refer to the manufacturer's label for drying time. Typically, primer requires a minimum two-hour drying time.

Apply a porch-and-floor paint to your floor. Begin by painting the floor's outer perimeter with a clean, angled paintbrush. Finish the remainder of the floor using a paint roller. Use smooth even strokes to avoid clumping. Latex floor paint provides low odor and quick drying time for interior floors. Again, follow the paint manufacturer's instructions for drying time, which typically is around two hours. Apply a second coat of paint after the first coat is dry completely and allow it to dry thoroughly. Darker colors, such as deep grays, blacks and browns, provide more visual depth.

Apply a polyurethane finish over a painted floor that is completely dry. Use a lambswool applicator pad attached to a rod for a professional finish. Allow the polyurethane finish to dry, typically in around eight hours. Follow with a second and third coat to add intense depth to your floor. Allow appropriate drying time between each coat and a minimum of 24 hours' drying time after applying the final coat before using the floor.
