What May Be Used To Fill Up Holes In Outside Wood Siding?

This Old House general contractor, Tom Silva, emphasizes the importance of repairing holes in exterior wood siding. He provides a comprehensive guide on how to patch small and large holes using wood filler, epoxy putty, and other methods. The type of filler used depends on the size of the patch, with waterproof exterior wood filler being suitable for holes up to and gouges narrower than 1/2 inch. For smaller holes or thin cracks, putty like DAP Platinum Patch Advanced Exterior Filler can be used.

To patch a hole in vinyl siding, use sandpaper, shop rags, a putty knife, exterior filler or putty, and exterior paint. Use wooden shims to lift the bottom of the siding above the course you plan to cut, then use a keyhole saw to finish cutting the siding. For the best guarantee against pop-out, use 7d or 8d nails and drive them into the studs.

Women and safety glasses are essential when applying wood filler, a paste- or putty-like substance. Apply the filler with a putty knife and smooth it. Epoxy repairs are some of the strongest and most long-lasting ways to patch wood, as they are structural and can be used anywhere. Plug and epoxy are the way to go for areas with holes and some rot. For holes and rot, cut out a larger area and cut a piece of wood that will fit the area.

Using 100-grit sandpaper, lightly sand any raised or rough edges around the hole, and remove any dust or debris from the area with a lightly water-dampened rag. By following these steps, you can maintain your home’s exterior and prevent deeper damage to your home structure.
