Hardwood flooring, although preferred by many homeowners, will invariably need maintenance such as applying a new coat of polyurethane paint. This paint, however, will require different application techniques than other types of paint.
First, remove dirt and debris from the floor surface. Because of its toxic fumes, you will need more ventilation in the room in which you are applying this paint. Open outside windows, use a fan, and wear a respirator to protect yourself against breathing these fumes. Avoid creating bubbles in the paint as you apply it. Apply three coats of the paint, allowing each to dry before applying the next.
