The PaintSource Guide to Painting and Protecting the Home’s Exterior

We hope you will explore below, the causes and simple solutions to common paint and finish problems that most homeowners find on new and old houses.

Common costly preventable problems include:

  1. Exterior Paint Failures resulting from the use of finger-jointed and / or Pre-Primed exterior wood siding, windows, and trim.
  2. Failure of inferior Deck Coatings and subsequent cupping, splitting, and warping of treated decking material.
  3. Concrete spalling, chipping, and pitting on driveways, patios, and walkways. The most common issue is adding too much water to the mix to make it easier to work. Too much water weakens the concrete and creates a pore structure that invites damage. You must take charge of the specifications for your concrete. Concrete must be sealed to prevent water damage.
  4. Use of Oil-based Paint on exterior wood leading to a brittle and non-breathable paint film that will crack and trap moisture; resulting in costly repaint, and wood deterioration or rot.
  5. The use of common Marine Spar Varnish and other Polyurethanes on wooden entryways and doors leading to moisture entrapment, brittle film cracking, and guaranteed coating failure on exterior wood surfaces.
  6. Moisture damage to a variety of surfaces and substrates resulting from the common use of inferior or incorrect Caulking Products, or the “one caulk does it all” approach.
  7. Poor results and coating failure when painting or staining Fiberglass Doors.
  8. Painting Wooden Doors
  9. Wood Doors- Natural and Clear Finish
