Start with a clean, dry surface. Use a putty knife or spreader to scoop a small amount of putty and press it into the defect, filling beyond flush. Smooth the surface with the edge of the knife, remove excess material, and allow it to dry. Once dry, it can be sanded to a smooth, paintable finish and then painted to match surrounding surfaces.

National N.C. Putty is formulated for flexibility and moisture resistance, reducing the likelihood of cracking, shrinking or peeling. It bonds well to wood and steel, provides good sandability and moldability, and seals against moisture, making it suitable for damp areas and a variety of substrates.
