|
|
Is Powder Coating more durable than liquid
paint?
Powder coated parts will be more flexible, UV
and chemical resistant than typical
enamel or aerosol coatings. Powder coated parts will also be more
corrosion
resistant than most aerosol coatings.
|
|
|
Can I powder coat over rust?
NO, just as in applying a quality liquid
coating you must remove the rust or corrosion first. This is
accomplished with abrasive blasting, wire brush, an angle grinder
with wire wheel, or sand paper.

|
|
Can I powder coat over paint?
If the coating can withstand the 400°F cure
then you can apply powder coat over it. If you are not sure of the
previous coating or there are signs of coating failure it is best to
remove the coating. This is easily accomplished with liquid paint
removers available at home improvement or hardware stores. You may
also remove the coating with abrasive blasting, wire brush, an angle
grinder with wire wheel, or sandpaper.

How do I prep my part?
It is best to powder coat over bare clean
metal. Be sure to wipe part with quality
laquer thinner or acetone before coating. Using the above methods of
paint
and rust removal will assure a high quality finish.

|
What is the average coverage of the powder?
The 1.5 oz. Powder Packet will yield
approximately 7 sq. ft. of coverage. Just as with liquid coatings
this will vary with the type of part to be coated. If the part is a
large flat object you will transfer more of the powder to the part
than if you were coating a part that had many holes. Transfer of the
powder to the part may decrease due to the powder being "blown”
through the holes of part to be coated.
|
|
|
Are any toxic fumes generated during the cure?
As with any coating process you must cure the
powder in a ventilated area. The powder does not contain the VOC’s
(volatile organic compounds) associated with solvent based aerosol
coatings, but you may notice a slight odor as the metal is heated to
400°F.

|
Will the WAI System obtain the same results as
a professional?
Your WAI Powder Coat System will give you
professional results if you follow the
instructions in this manual. The powder coating material itself is
the same chemistry
as what is used by professionals.

|
|
Why use
powder in place of liquid or aerosol coatings?
Speed of application, faster clean up, no
hazardous solvents, environmentally friendly, more durable and
flexible than most liquid coatings, very chemical resistant and the
elimination of runs, drips, sags and defects.
