SOME COMMON
EXTERIOR PAINT PROBLEMS
Peeling:
Loss of paint due to poor adhesion (often caused by moisture).
Where there is a primer and top coat, or multiple coats
of paint, peeling may involve some or all coats.
Alligatoring:
Patterned cracking in the surface of the paint film resembling
the scales of an alligator.
Blistering:
Bubbles resulting from localized loss of adhesion and lifting
of the paint film from the underlying surface.
Chalking:
Formation of fine powder on the surface of the paint film
over time, which can cause color fading. Although some degree
ofchalking is a normal way for paint film to wear, excessive
film erosion can result in heavy chalking.
Cracking/Flaking:
the splitting of a dry paint film through at least one coat
of paint, which will lead to the complete failure of the
paint. Early on, the problem appears as hairline cracks;
later, flaking or paint chipping occurs.
Mildew:
Black, gray or brown areas on the surface of paint.
Nailhead
Rusting: Reddish-brown
stains on the paint surface above the nailheads.
