Chipboard consists of wood chips, sawdust and resin bonded together to create sheets similar to plywood that are often used in homes as a subfloor. Chipboard may have a very rough, textured surface that appears to be small bits of wood pressed together, or it may have a smooth finish created by a thin layer of wood veneer. Regardless of the type of chipboard on your floor, you can paint it with standard house paint. A rough chipboard will require several more layers of paint to ensure that the paint fills in all of the tiny cracks and crevices in the floor to create a smooth surface.

Paint chipboard subfloors to give them a finished appearance.

Step 1

Sweep the chipboard floor to remove any dust or dirt from the surface before you begin painting.

Step 2

Fill any large gouges in the floor, or the seams between the sheets of chipboard, with wood filler. Smooth the wood filler flat with a putty knife and allow it to dry for 24 hours.

Step 3

Apply one coat of latex paint to the floor with a paint roller. Start in the corner farthest from the door to avoid painting yourself into a corner. Let the paint dry completely. The chipboard will absorb some of the paint and the floor will appear extremely rough.

Step 4

Apply two to four additional coats of paint to the chipboard floor with a paint roller. Let each coat of paint dry completely before you begin to apply the next. Continue adding layers of paint until you are satisfied with the floor's appearance.

Step 5

Apply a layer of clear-coat polyurethane to the floor with a paint roller when the paint is completely dry. Let the polyurethane dry, then repeat the process to add two to four additional layers of polyurethane to the floor.
