Close up image of a surface that has a brownish or tan discoloration.

Causes

  • Failure to adequately prime and seal the surface before applying the topcoat.
  • Use of a primer that is not sufficiently stain-resistant.
  • Excess moisture escaping through the exterior walls, which can carry the stain to the paint surface.

Solutions

  • Identify and correct any possible sources of excess moisture. After thoroughly cleaning the surface, apply a high-quality stain-blocking wood primer. If possible, prime all six sides of the wood.
  • Remove any stains with oxalic acid or a commercially-available wood cleaner designed for removing tannin stains. Allow the surface to dry thoroughly for at least 48 hours (depending on the existing weather conditions).
  • In extreme cases, a second coat of primer can be applied after the first has dried thoroughly.
  • Finish with high-quality paint.
