What about the exterior walls, what causes
hairline cracks in paintout there?
a. Intercoat Peeling
The prime conditions wherein cracks in paint are
observed on exterior walls are
· Causes of Intercoat
Peeling Improper preparation of the wall surface prior to the painting session is one of
the main reasons for Intercoat peeling. The semi-covered or the covered areas
are more susceptible towards Intercoat peeling as these surfaces do not receive
enough rainfall for rinsing off the airborne pollutants. Thereby, the pollutants
remain affixed to surface and the painted layer starts loosing up and eventually
peels causing hairline cracks.
· Recommended Treatment
The recommended treatment is prevention of the cause, which means the wall needs
to be washed and scrapped properly before the application of paint.
b. Solvent Blistering
· Causes of Solvent Blistering
This very type of hairline cracks is very rare and usually caused by action of
action of environmental heat over the applied paint solvent. When paints rich in
solvent film are applied in direct sunlight, consequently the topmost layer
dries too quickly leaving the solvent trapped under the dried layer. This causes
blisters on the painted wall, which over the time turns into hairline cracks.
This problem is experienced usually with the darker paint colors.
· Recommended treatment
The treatment to avoid the occurrence of hairline crack is to fix the blister as
soon as spotted. Checking the prolonged condition of blisters can rightfully
prevent hairline cracks. The blisters can be worked by scrapping manually and
then sanding to the next layer and thereafter painting with color.
· Causes of Wrinkling
Like Intercoat peeling, wrinkling is another case of faulty application of
paint. The basic cause of wrinkling is drying of topmost layer before the
underneath layer. The reasons which cause speedy drying of topmost layers are,
extensively thick application of paint, application of the next coat before the
previous coat is actually dry, inadequate brushing technique and application of
paint in much higher temperature than advised by the manufacturer. The prolonged
condition of wrinkling often causes hairline cracks.
· Recommended treatment
The treatment to avoid hairline cracks in this case is to prevent wrinkling or
fixing the issue as soon as observed using patch and paint DIY kits.
