Paint spraying problems questions
and answers
Q: I have an
Anodized product and a paint spraying company has told me they can re Anodize it
on site, is this true ?

much like chrome plating.
Q: Can you tell me what paint to use when repairing powder coated products
A: Sorry I'm sure you will appreciate it is not good
business practice to give away your techniques to the competition
Q: Can an item be powder coated on site
A: No again it is a workshop process which requires an
oven or a furnace.
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.
Q: The paint finish has small craters in
it, like fish eyes.
A: This is called silicone, caused by many products the
most common is silicone sealer or spray near your work, WD 40, furniture polish,
silicone spray, paraffin heater etc. Siliconing is worst in cold conditions,
always de-grease your work and apply a very light first coat to help avoid this
problem.
Q: The paint finish is lumpy almost like an orange peel.
A: The orange peel finish is caused by under thinned paint
of spray pressure is to low.
