Tips

  • Use clear caulking so the caulking color doesn't show.
  • Apply a generous amount of caulking to ensure a complete seal and prevent cracking.
  • Don't use too much pressure when painting to avoid compromising the caulking seal.
  • Paint in one direction to avoid smudging.
  • Don't touch the wet paint with a rag to avoid smudging or damaging the wallpaper.

Common Mistakes to Avoid

1. Uneven Caulking Application

Reason: Inconsistent pressure or technique during caulking leads to gaps, bumps, and an unprofessional look.
Solution: Reapply a thin, even bead of caulk, smoothing it with a wet finger or caulking tool.

2. Caulk Not Properly Painted

Reason: Insufficient paint coverage on the caulk leaves it visible and detracts from the seamless finish.
Solution: Apply several thin coats of paint to the caulked area, ensuring complete coverage.

3. Using the Wrong Type of Caulk

Reason: Using a caulk not designed for interior/exterior use or one that shrinks/cracks over time will compromise the long-term seal and look.
Solution: Choose a paintable caulk specifically designed for the location and application (interior/exterior, flexible/rigid).
