Proper planning is the key to the
success of any project. Proper preparation requires having the right
materials, tools, abrasives and a clean area to spray.
The first step in preparation is to
remove the surface of all contaminants such as dirt, grease and waxes.
Even when the surface is to be sanded, it is best to remove any film on
the surface as sanding a dirty surface will further push contaminants
into the surface. Use a cleaner or degreaser with a mild solvent base
that dries fast.
Next the surface should be thoroughly
sanded or scuffed. It is necessary to evaluate the surface. If the
existing coating is an O.E.M. finish in good condition, it may be
prepared by dry D/A sanding, wet sanding or scuffing.
If the existing coating is in poor
condition, stripping down to the bare substrate is recommended. Use
liquid strippers, aggressive sanding, medial blasting, etc.
Bare metal should be cleaned of any
contaminants and oils, then coated with self etching primer. Use
standard automotive grade primers. Auto Air Colours work over any
automotive filler primer. After automotive primer has been applied,
prepare surface by scuffing or sanding thoroughly eliminating all
surface imperfections. Follow manufacturer’s directions. Once the
surface has been thoroughly sanded or scuffed, the next step is the
application of Auto Air Base Coat Sealer White or Dark.
When working with bare or exposed
metal, an automotive primer must be used before application of Auto Air
Colours. Auto Air Colours are water based and may corrode exposed metal.
Auto Air Colours work over any automotive primer.
Fibreglass should be scrubbed
thoroughly, washed and dried. Repair and fill any deep scratches, dents
and surface imperfections prior to painting. Machine sand, hand sand,
wet sand or scuff with a 3-M Red or Gray Scotch-Brite Scuff Pad®.
Once the surface has been thoroughly
sanded or scuffed, the next step is the application of Auto Air Base
Coat Sealer White or Dark. The surface is then ready for the application
of Auto Air Colours
Auto Air Colours must be thoroughly
shaken prior to use. Auto Air Colours have a high pigment load in a low
viscosity binder. Settling of the pigment is intended. Auto Air Colours
must be thoroughly shaken prior to use. Some colours in the 4300FX
Colours Series, such as the 4330 Metallic White (fine) and 4331 Metallic
White(coarse), and then 4100 Series Aluminium Bases may need vigorous
shaking due to their heavily pigmented metallic flakes.
There are no time windows when
working with Auto Air Colours, Unlike most other automotive base coat
systems, there are no time windows necessary for proper application of
Auto Air Colours. Additional coats may be applied at any time once the
underlying coat has dried. Additional coats may be done within minutes
of the fast coat or several days may pass before the next coat is
There is no time window for clear
coating Auto Air Colours. The clear may be applied as soon as the
colours have been heat cured and are thoroughly dried. However, the
clear will still work excellent with the colours if several days pass
Auto Air Colours are best used under
warm, dry and dust free conditions. Createx recommends using Auto Air
Colours under shop conditions with a minimum temperature of 70°F. Auto
Air Colours are water based and lose excess water through evaporation
and will retard the Auto Air Colour’s curing process. Working in
excessively cold or humid conditions requires an extended heat curing
When working in conditions under the
recommended temperature, a heat lamp or other heat source to warn and
dry Auto Air Colours is essential. Auto Air Colours must be thoroughly
dry prior to clear coating.
To ensure colours are free of any
contaminants, pass Auto Air Colours through a filter prior to spraying.
Createx takes great care and pride in making its Auto Air Colours. As a
part of its quality control process, Createx employs multiple filtration
steps to ensure the colours are free of contaminants. However, small
bits of hardened paint may be on the caps, especially once the caps on
the Auto Air Colours bottles have been opened and the colours are
exposed to fresh air. These hardened bits of paint may be mixed with the
rest of the paint when the bottle is shaken. These hardened bits will
create imperfections when sprayed. Although such occurrences are not
common, it is best to pass the colours through a filter or screen prior
to use. Pass the colours through a fine mesh paint filter prior to use.
Another way colours may be properly filtered is to cut out a small area
from the filter screen, unscrew cap from bottle, place the cut screen
over the bottle’s opening and screw the cap back onto the bottle’s
Apply colours in lightly layered
coats, allowing coat to dry prior to the application of the next coat.
Working in lightly layered coats is important to ensuring successful
results. As evaporation is a part of the curing process, working in
light layers ensures all excess moisture will evaporate and that colours
will properly adhere to the surface.
Often, multiple layers of 2 to 5
coats are applied to achieve the desired colour. Coat refers to applying
enough colour so that the layers "wet". Wetting is when the
individual colour particles adhere with one another creating a wet look
on the surface. When the colours are applied on a single light pass they
look dry on the surface. After 2 or 3 light passes, they look wet
because they link up with one another creating a continuous film. This
is one coat; 2-3 light passes until the colour is wet. At this point,
the colour can be cured with heat with a heat gun or other heat source
until dry to the touch. When using a heat gun, it is important to move
the hot air source, not staying on a particular point for too long. This
technique and much more information is demonstrated on the Createx Auto
Air Colours User Guide Video and DVD.
Use Base Coat Sealer as first coat.
Base Coat Sealer has excellent adhesion and coverage and should be used
as the initial coat. For more information, refer to Base Coat Sealers on
When working on bare metal, an
automotive primer must first be used. Auto Air Colours are water based
and should not be used directly on metal to avoid corrosion. For more
information, please refer to "Preparation" on page 2.
Auto Air Colours need to be cured
with heat. The heat source may be a hot air gun, heated/infrared lamp,
heated spray booth, etc. All coats should be cured with heat before the
next coat is applied. It is especially important to cure with heat the
first coat and the final paint job prior to clear coating.
Curing Auto Air Colours in humid or
cold damp conditions requires extended exposure to heat. Auto Air
Colours are water based and as such, evaporate excess water when they
cure. Cold and humid conditions inhibit the evaporation of the excess
water, which retards the curing process. To counter this, Auto Air
Colours should be exposed to heat from a hot air gun or heat lamp for an
extended period of time. Length of time varies, but colours should be
dry to the touch. When working i n light coats as recommended, extended
drying time should be about double the amount of time allowed to cure
colours. Cure colours prior to sanding and masking. When applied in
light coats and cured, colours will not lift. Tape with most any
automotive tapes and fine line tapes. Colours may lift when not cured or
used improperly by building coats too thickly.
Auto Air Colours may be thinned with
Auto Air Reducer. Auto Air Colours are ready to spray out of the bottle,
but for use with airbrushes smaller than what is recommended on the
colour’s label, thin with Auto Air Reducer.
Auto Air Colours are compatible with
any urethane or polyurethane automotive clear. Createx has yet to find a
urethane or polyurethane clear coat that did not work excellent with
Auto Air Colours. There is no required time window for applying the
clear after applying the Auto Air Colours. The colours can be cleared
right after the colours have been cured with heat and are thoroughly
dry. For more information, please refer to the clear coating instruction
in this guide.
Curing Auto Air Colours
Auto Air Colours are water based and
evaporate excess moisture when they cure. This is why it is important to
work in light layers as heavily built layers will not allow the excess
water to evaporate from the underlying layers. Light layers ensure the
Auto Air Colours properly cure.
Auto Air Colours cure through the
addition of heat from a heat gun, a shop heat/infrared lamp, heated
spray booth, etc. Hot air causes the Auto Air Colours’ binder to
crosslink, which creates a permanent paint film. If area is too large to
cure with heat, use Auto Air Catalyst and make sure colours are allowed
to thoroughly dry.
As demonstrated in the Auto Air
Colours User Guide Video and DVD, the colours are cured by applying heat
from a hot air gun to the colours after spraying a thin coat. The
colours do not need to completely dry prior to using a hot air gun when
the coat is a thin layer of 2-3 passes. The temperature does not need to
be excessively hot. Making colours warm to the touch will do, although
Auto Air Colours are able to withstand temperatures in excess of 400°F.
Exposing colours to extreme heat when curing may risk blistering of
Cold and humid conditions inhibit the
evaporation of water, which retard the Auto Air Colours’ curing
process. To counter this, Auto Air Colours must be cured by heat; heat
gun, heat lamp, heated spray booth, etc.
The length of time required to cure
the colours varies as temperatures, humidity and amount of material
sprayed affect the curing time. However, the process should be quick
when coats are applied in light layers as recommended. When using a hot
air gun, it is important to use it at 2-4 inches away from the surface
and keep the air moving so as not to stay on a particular area for more
than a few seconds.
Coating Auto Air Colours
Auto Air Colours are compatible and
work excellent with all urethane and polyurethane clear coats of any
grade. Createx tested many clears with the Auto Air Colours during its
development and found all clears to perform excellent with the Auto Air
Colours. Clear coats have a death grip on Auto Air Colours with no
The secret to the Auto Air Colours
superior compatibility with clear coats is its porosity. Clears are
absorbed into the Auto Air Colours creating a strong, uniform bond.
There is no lifting or peeling and the results are long lasting
Auto Air Colours do not have to be
sanded prior to clear coating. If fingerprints and smudges need to be
removed from the Auto Air Colours’ surface prior to clear coating use
a mild solvent based cleaner or degreaser, such as DuPont’s Final
When applying the clear, lightly dust
on the first coat allowing it to be absorbed and acclimated into the
Auto Air Colours. Allow for the proper flash time as recommended by the
clear manufacturer. Then apply 2-3 additional medium wet coats as per
the manufacturer’s instructions. You won’t be disappointed by the
