Peeling from Wood


Occurs when wet wood expands and contracts from moisture and temperature change, causing the paint film to loosen, crack and roll at exposed edges and fall off.

  • Moisture or water seeping into the painted wood surface through uncaulked joints, worn0out caulking or leaks in roofs or walls.
  • Exterior moisture escaping through exterior walls (more likely if paint is solvent-based)
  • Vegetation giving off moisture too close to wood siding
  • Painting damp wood
  • Power-washing wood and not allowing sufficient time for the wood to dry
  • Inadequate surface preparation
  • Painting wood boards or siding too close to the ground
  • Using a low-quality paint

  • Ensure wood surfaces are clean and dry.
  • Prepare the surface according to the direction specified on Technical Data Sheet.
  • Follow the instruction on Technical Data Sheet
  • Inspect the outside of the building to identify and eliminate all sources of moisture, specially windows, trim areas and other joints.
  • Repair leaks in the roof, clean out gutters and downspouts.
  • If moist air is rising from the ground through the masonry, waterproof the foundation with a specially designed coating. Remove the portion of the wood that is touching the ground.
  • Remove all loose paint with a scraper or wire brush, down to the bare wood if necessary.
  • Power washing is recommended for larger areas and allow wood to dry for three to five days before priming.
  • Primer bare wood with the appropriate primer.CM 9000 QD White Undercoat/ CM 6000 AC Primer 700/ CM Economical Primer 701/ CM Economical Primer B220
