Nail Holes & Nail Head Stains| Common Painting Problems
Moisture can sit in nail holes around the house and do damage to your siding. You’ll see areas where there are nail holes beginning to swell due to moisture getting into those areas. If you only paint over these, there will still be a small pocket for water to sit. We recommend caulking these nails holes to leave an even surface for moisture to flow off of rather than sitting there breaking down the paint.
