BULLES SOUFFLURES
Description of problem:
During oven drying, the air withheld underneath the paint in the primer / fillers, the
putty, the welding joint, etc… expands and bursts through the paint film.
Causes:
– Bad application of the putty. Putty is applied in thick layers and air allowed
to be trapped in.
– Poor sanding
Preventive measures:
– Apply the putty with the proper application technique.
Do not incline the knife at a small angle with respect to the surface as
this allows the putty to roll under the knife.
– Sand well the edges.
Remedy:
Remove the paint all the way to the bare metal, clean with Valox
(based on phosphoric acid), prime and paint.
