Common House Painting Problems and Solutions
2

• All exterior and interior paint problems can be
  avoided or corrected by considering a few things.
  Any exterior paint job must be started by
  cleaning, scraping, and repairing the surface.
  Chalking, blisters, peeling, cracking, and stains
  must be dealt with before applying a new coat of
  paint. Unless the cause is discovered and
  corrected, the problem will reappear and ruin
  your fresh paint job.
• Lets check out the causes and solutions to some
  common household paint problems and paint
  failures.

3
BLISTERING

• Blistering paint is identified by small to medium
  sized bubbles or blisters under the paint film
  and is most common on wood siding and trim.

4
CAUSES AND SOLUTIONS

• CAUSES
• Painting in direct sunlight or on a surface that
  is too warm, especially when applying a
  dark-colored solvent-based coating
• Applying an oil-based or alkyd paint over a damp
  or wet surface
• Excess moisture escaping from inside through the
  exterior walls
• Exposure of a latex paint film to excessive
  moisture.
• SOLUTIONS
• Caulk or re-caulk open joints, check for roof
  leaks
• Apply paint only within recommended environmental
  ranges

5
EFFLORESCENCE

• Efflorescence is identifiable by crusty white
  salt deposits that bubble through the paint film
  from a masonry structure due to heavy moisture
  migrating through exterior walls from inside the
  home. Salts in the brick or concrete become
  dissolved with water and then leach to the
  surface as the water evaporates.

6
CAUSES AND SOLUTIONS

• CAUSES
• Poor paint surface preparation.
• Inadequately waterproofed basement walls allowing
  ground water penetration.
• Painting masonry construction before the concrete
  or mortar had adequately cured and dried out.
• Cracks in masonry wall allowing water to get
  behind masonry wall.
• SOLUTIONS
• Remove any prior trace of efflorescence before
  repainting
• Eliminate any sources of moisture
• Apply a masonry primer or sealer

7
PEELING PAINT

• Peeling paint is a very common paint problem but
  can be caused either by moisture or poor
  adhesion. Peeling due to poor adhesion is
  characterized by the paint peeling and separating
  from an earlier paint layer (inter-coat peeling)
  or from the substrate leaving some paint behind.
  Sometimes portions of earlier paint layers are
  visible under the curling, peeling paint layer.

CAUSES AND SOLUTIONS

• CAUSES
• Penetration of moisture into the home through
  uncaulked joints, deteriorated caulk, leaking
  roof, etc.
• Excess humidity or other moisture escaping from
  within the home through the exterior walls
• Inadequate surface preparation
• Applying latex paint under conditions that hinder
  good film formation
• Applying an oil-based paint over a damp or wet
  surface
• Solutions
• Caulk or re-caulk open joints and check for roof
  leaks
• Adequate surface preparation
• Apply paint within recommended environmental
  ranges

9
MILDEW

• Mildew is a fungus feeding and growing on the
  paint film or caulk and is identifiable by its
  grey, brown, green or dark black "splotchy" spots.

10
CAUSES AND SOLUTIONS

• CAUSES
• Combination of moisture, poor ventilation and
  lack of direct sunlight. Underside of soffits and
  eaves are especially prone to mildew.
• Painting over a surface or prior paint film that
  still had mildew.
• Use of low quality paint having inadequate
  mildewcide.
• Not priming bare wood before painting.
• SOLUTIONS
• Test for mildew using household bleach
• Properly treat and prime the surface before
  applying a paint or stain
• Avoid using flat paints and alkyd paints for
  exterior use
