PRIMER COAT APPLICATION DIRECTIONS
SECTION 3-PCD
Overview:
These directions are provided to
assist you with the proper application of your primer
coats. Following these directions will yield excellent
results. If presented with an unanticipated problem
during primer application and sanding, obtain advice
from your jobber or those with a greater level of
expertise. Do not take shortcuts! Your primer coat
application is the foundation for your basecoat and
additional topcoats. A well-prepared primer foundation
is essential for successful custom painting projects.
All recommendations are based on minimum shop
temperatures of 70º F. Re-coat times can be
dramatically affected by temperature. Lower temperatures
will create longer cure and dry times. Higher
temperatures will shorten cure and dry times.
Basecoat colour will determine which of our primer
colours you will be using. The entire object must be
primed with one uniform primer colour. Our Epoxee
Primers do not require the application of a sealer prior
to Basecoat applications. Our Epoxee Primers will save
you time and money.
Considerations:
The colour selection of your primer
will usually depend on the predominant colour of your
basecoat. The following are considerations and are not a
rule because of the unlimited variables in Basecoat
colour selection. Your jobber can assist you in making
the correct primer colour selection.
Sparklin’ Metallic Basecoat colour
series pre-fix number 08, Sparklee Silver Metallic
Basecoat product number 08-100, our lighter coloured
Pearl Basecoats, colour series pre-fix numbers 76, 77,
79, or any of our lighter Solid Coloured Basecoats5 use
X-otic Colours White Epoxee Primer, product number
01-100. When a dark colour selection has been made in
one of the above categories, you may wish to select our
Black Epoxee Primer, product number 01-200. This will
provide faster basecoat coverage. Some custom painters
select our Black Epoxee Primer or our tintable Epoxee
Primer with Pearl Basecoats to achieve different
effects.
If you have selected one of our Mirage Pearl
Basecoats, product pre-fix number 14, or one of our
Mirage Imagin’ Basecoats, product pre-fix number 20,
Pearl Imagin’ Basecoat product pre-fix number 21, or a
very dark or Black Basecoat, you will need our Black
Epoxee Primer, product number 01-200.
Tintable Primer product number 01-300
may be used for faster Basecoat coverage and to more
closely resemble Basecoat colour. In the event of a rock
chip or scratch, the damage will be less obvious using a
Tintable Primer. Your jobber will provide a tinted
primer in the same colour family as your Basecoat.
Preparation:
Important Safety Note:
Wear correct safety equipment:
respirator, goggles, gloves, painters suit, and a
properly fitted NIOSH approved respirator.
1. The surface to be primed should
have been prepared according to the specifications as
outlined in the Project Preparation Directions, Section
2-PPD.
2. If the surface to be primed has
become re-contaminated by dust, dirt, fingerprints,
etc., solvent wash with X-otic Colours Epoxee Reducer
product number 54-100. Dry, using clean lint free
absorbents.
3. Allocate a sufficient block of
time to apply all necessary primer coats.
4. To prevent body oil transfer from
hands, wear lint free gloves whenever possible. Do not
touch objects to be painted with bare hands or skin.
Mixing:
X-otic Colours Epoxee Primers are
based on a two-component system. Shake and stir
each component separately and aggressively before
combining. By volume, measure one part Epoxee Primer
(Part A) and combine with one measured part Epoxee
Primer Catalyst (Part B). In other words, combine at a
1-to-1 ratio by volume.
Then, stir or shake this mixture
aggressively. Problems with two part primers are almost
always attributed to improper mixing, improper mixing
ratios, or lack of aggressive shaking and stirring. This
mixture requires no induction time. Always measure!
For maximum film build and filling do
not reduce. If reduction is necessary, reduce 10% with
Epoxee Reducer, product number 54-100.
Filter:
Strain the primer mixture into gun
cup using a fine mesh cone strainer.
Test Spray:
Test spray on a scrap item to adjust
air pressure, fan, and paint flow to suit the spray
equipment being used. You will need a wide fan along
with a flow that will wet the surface. Maintain a gun
distance of approximately 6 inches.
A mock simulation of the primer coat
application is a good idea. The simulation of any
application sequence in your custom painting project
will yield better results.
We suggest you save this scrap item
for additional test spraying of Basecoat and all topcoat
applications. This panel should also be used as an
indicator of potential bleeding of Basecoats or Candee
Mid-Coats when artistic application coats are planned.
This issue is addressed in detail in Product Application
Directions, Sections 4-BCJD and 5-PBJD.
Application Directions:
Beginning with your first primer
coat application and all successive primer coats,
perfect your spraying overlap pattern of 50%. Keep the
gun a consistent distance from the object --
approximately 6 inches. Keep the gun parallel to the
surface of the object.
Pay close attention to contours and
areas where primer may accumulate or run. Paying
attention to these potential problem areas, at this
time, will provide you with important information that
will assist you in better application of your Basecoats
and topcoats when they are applied.
Do not section off large objects,
stopping and starting the gun. Keep the trigger pulled
and walk the distance of the object to maintain uniform
film thickness. Starting and stopping the gun typically
means there will be variations in coverage. Now is the
time to perfect application techniques. When you
move to later applications you will have better results
-- especially with Candee Mid-Coat applications where
uniform coverage is essential.
Apply two wet coats over all repair
areas. Then, apply 3 to 4 wet coats over the entire
object. Each coat in the last area sprayed should have
“flashed off” all solvent and appear dull before
applying your nextcoat. Monitor each coat closely.
When applying wet heavy build coats, allow a minimum
“flash off” time of 30 minutes. Maximum re-coat window
is one hour. Less time will be needed on lighter coats.
We do not recommend application in temperatures below
68°F.
Note: When spraying over a properly
prepared O.E.M. finish, apply one light bond coat (tack
coat), followed by one or two medium wet coats. Allow
all solvent to “flash off” between coats.
Important Reminder: You will be
putting on multiple coats of primer with a maximum
re-coat window between coats of sixty minutes at 68° F.
Be certain you have allocated sufficient time to apply
all primer coats. To maintain maximum merging of coats,
all coats must take place within the specified re-coat
windows. Never apply this product wet-on-wet.
Curing:
Minimum cure time: 15 hours at 70ºF.
We recommend 24 hours at 70ºF for easiest sanding. X-otic
Colours Epoxee Primers may be force cured at 140°F for
45 minutes.
Sanding Guide Coat:
The sanding guide coat may be applied
before or after curing. The sanding guide coat is a
spray application of a contrasting lacquer primer colour.
Your jobber will furnish this product. It is sprayed as
a dusting coat that will lightly cover the primer
surface. As you begin sanding, the guide coat will
reveal any deep sand scratches, low spots, and other
imperfections in the primer coat. The guide coat will
help minimize the amount of primer removed by sanding
and shorten the time required to sand.
Note:
The guide coat must be completely
removed before topcoat applications.
Sanding:
We recommend wet sanding with 400
grit wet/dry sandpaper. Or, sand with 240 to 400 grit
dry. Use a small amount of non-filming dishwashing
liquid added to your water. This will minimize transfer
of body oils during sanding. Wet sanding will also
help keep sandpaper from loading and the sandpaper will
better conform to the contours of the object.
Use your sanding guide coat to reveal areas where
additional spot applications of primer may be necessary.
Sanding may also reveal pinholes, low spots, and deep
sand scratches over repair areas. If these flaws cannot
be removed without exposing body filler -- sand these
areas using 80 grit dry sandpaper. Apply additional
filler or glazing. Use only fillers or glazes that
require a hardener. Let fillers cure, sand, clean, and
then apply two to four coats of additional primer to the
repaired area.
To prevent body filler bleed through or staining,
repaired areas must have a minimum of 2 mils of primer
remaining after final sanding. Each wet coat of primer
will cure down to slightly less than 1 mil.
Never final sand with finer than 400 grit or
adhesion of Basecoat will be impaired.
Keep hands off object while sanding. As sanding
progresses, oil from hands could be sanded into the
primer causing inevitable problems. Wear lint free
gloves.
Cleaning:
Wash the
entire object with soapy warm water. Use a dishwashing
liquid that leaves no residue or film. Complete a
thorough rinsing. Blow off excess water, towel dry with
lint and contamination free absorbents. Do not touch
object with bare hands! Doing so will contaminate
the surface of the object and a re-cleaning will be
required. Wear lint free gloves.
If the
object is thoroughly dry, apply Basecoats as soon as
possible to avoid re-contamination.
Next
Application Sequence:
You are now ready for Basecoat
applications. Refer to Product Application Directions,
Section 4-BCJD and 5-PBJD before you begin application.
Remember: the entire object must be primed one
uniform colour.
