Paint spraying problems questions and answers
Q:The item I have
spray painted has a white and cloudy finish.
A: This is called paint Blooming normally caused by
cold or damp conditions, the gases used as propellants in aerosol paints
will make this problem worse, also cheap grade thinners, blooming is
normally associated with Cellulose paints.
Q: The paint finish has
a crackling effect almost like it has paint stripper on it.
A: This is caused by the original paint finish
not being compatible with the paint you have just applied, a very common
problem when over coating Synthetic paints with Cellulose or some 2 pack
products..
Q: The paint
finish has tiny air blisters just under the surface.
A: This is called Micro-Blistering, causes are
cheap thinners or paint contaminated with water or oil, if using an air
compressor it can be water/oil in the tank and airline. Another cause can be
solvent entrapment, to much paint applied without leaving the correct drying
time between coats. Micro blistering can occur several months later,
normally when the weather gets damp.
Q: The paint finish has
cracks at random almost like an earthquake.
A: This is called Crazing, the most probable
cause is to many paint applications, normally found on bonnets and roofs of
cars. Crazing can also be caused by incompatible paint products or incorrect
re coating times. Constant use of car washes can also cause crazing.

small craters in it, like fish eyes.

always de-grease your work and apply a very light first coat to help avoid this
problem.
