User Guide
INTRODUCTION
System Three® manufactures a marine primer and topcoat that offer increased
environmental friendliness without sacrificing performance. Since these
products thin and clean up with water, they are less hazardous and less costly
to use than their solvent-containing counterparts. Because they are non-
flammable, they can be used where flammable solvent-based paints cannot. Once
cured, the combination is water and chemical-resistant while offering maximum
protection from the sun and weather for topside watercraft applications.
RECOMMENDED USES:
- Epoxy coated fiberglass
- Epoxy coated wood
- Polyester gelcoat
- Existing paint systems
PRODUCT DESCRIPTIONS
PENNANT PRIMER
Pennant Primer is a waterborne, two-component epoxy-polyamide primer. It
contains no harmful solvents and cleans up with water. It bonds tenaciously to
most clean, sanded surfaces while providing a friendly surface for water and
solvent-based topcoats.
For marine applications, the Pennant Primer can be applied above or below the
waterline. Pennant Primer will also seal fairing or other filler work before
top coating.

SUBSTRATE REQUIREMENTS
EPOXY COATED FIBERGLASS
For best results, use System Three non-blushing SilverTip or Clear Coat epoxy.
Some epoxy resin systems can leave an amine blush on the surface. Amine blush
can interfere with the adhesion of the Pennant Primer and Topside Paint.
- If you are using SilverTip or Clear Coat Epoxy for the fiberglass layup, skip stepping number 3.
- Remove surface blush by using a Scotch-Brite pad with detergent and warm water. Then flush the surface with fresh water.
- Sand the epoxy surface with 150-grit paper, making sure to completely degloss the surface.
- After sanding, vacuum or blow off the surface with clean, dry shop air to remove sanding dust.
- Wipe the surface with denatured alcohol and clean rags in preparation for Pennant Primer.
- Proceed to Means of Applying Pennant Primer and Paint for details specific to your application process.
EPOXY COATED WOOD
Marine topside exterior wood components need to be epoxy sealed before
applying Pennant Primer and Topside Paint. The wood surface must be clean and
dry (verify with a moisture meter that levels do not exceed 12%).
Additionally, the substrate must be structurally sound with minimal
deflection. For best results, use System Three non-blushing SilverTip or Clear
Coat epoxy. Some epoxy resin systems can leave an amine blush on the surface.
Amine blush can interfere with the adhesion of the Pennant Primer and Topside
Paint.
- Sand the bare wood using 80-100 grit sandpaper. Make sure that all edges and corners are rounded over. Sharp edges promote poor epoxy coverage, which can lead to a premature failure of the coating system.
- After sanding, vacuum or blow off the surface with clean, dry shop air to remove sanding dust.
- Fill surface imperfections with SilverTip QuikFair. Sand repair areas until smooth using 100-120 grit paper.
- Repeat step 2.
- Apply a thin seal coat of epoxy with a 1/8” nap foam roller. Ensure that all surfaces are coated with epoxy, paying particular attention to the end grain.
- Apply 2-3 additional heavier coats of epoxy. Recoating without sanding can be done within 72 hours of the last coat. If sanding is necessary, use 150-grit sandpaper.
- Allow the epoxy to cure sufficiently, usually 48 hours at 70°F, before sanding in preparation for Pennant Primer.
- If you used an epoxy that blushes, make sure to remove the surface blush before applying Pennant Primer. Use a Scotch-Brite pad with detergent and warm water. Then flush the surface with fresh water.
- Sand the epoxy with 150-grit sandpaper.
- Wipe the surface with denatured alcohol and clean rags in preparation for Pennant Primer.
- Proceed to Means of Applying Pennant Primer and Paint for details specific to your application process
POLYESTER GELCOAT
Polyester gel coats often have mold release agents as well as wax
contamination on the surface. Pennant Primer can be successfully applied over
polyester gel coats provided the surface is free from contaminants and well
sanded.
- The surface should be cleaned thoroughly using a Scotch-Brite pad with detergent and warm water.
- Follow with a wax stripper. Flush the surface with plenty of fresh water.
- Once the surface is clean and dry, thoroughly sand the gel coat using 80-100 grit sandpaper.
- Fill any surface crazing or other surface imperfections with SilverTip QuikFair. Sand the repaired areas until smooth with 100-120 grit paper.
- After sanding, vacuum or blow off the surface with clean, dry shop air to remove sanding dust.
- Wipe the surface with denatured alcohol and clean rags in preparation for Pennant Primer.
- See below the Means of Applying Pennant Primer and Paint for details specific to your application process.
EXISTING PAINT
Pennant Primer and Paint can be applied over most existing paint surfaces,
provided that they are sound and free from wax and other contaminants. Before
committing to complete paint resurfacing, pretesting is recommended to ensure
adequate adhesion is present with the existing paint and the Pennant Primer.
- If the existing paint has been waxed, first clean the surface. Scrub the paint with a Scotch-Brite pad in conjunction with detergent and warm water. Rinse the surface with plenty of fresh water.
- Follow with a wax stripper. Flush the surface with fresh water
- If necessary, fill surface imperfections with SilverTip QuikFair. Sand repair areas until smooth with 100-120 grit paper.
- Sand the existing painted surface with 150-grit sandpaper. Make sure to completely degloss the paint.
- After sanding, vacuum or blow off the surface with clean, dry shop air to remove sanding dust.
- Wipe down the paint with denatured alcohol and clean rags in preparation for Pennant Primer.
- Proceed to Means of Applying Pennant Primer and Paint for details specific to your application process.
MEANS OF APPLYING PENNANT PRIMER AND PAINT:
Pennant Primer and Topside Paint can be applied by the roll and tip method or
spray application.
The Roll and Tip Method:
Application Conditions: When applying Pennant Primer and Topside Paint with a
roller and brush, be mindful of the ambient temperature and humidity
conditions. Extreme environmental conditions can negatively affect how the
paint flows out once applied. Best results are achieved in the average
temperature and humidity range of (70-80°F and 50-80% relative humidity)
It’s advisable to work in an environment where the surface is protected from
the sun and the wind. Surfaces exposed to heat from the sun and the wind will
set up too quickly, resulting in poor flow out.
Pennant Primer
Mixing: Stir Part B thoroughly to remix any settled material. Mix 4 parts
Hardener Part B with 1 part Resin Part A by volume and stir thoroughly for 2
minutes. Allow the material 15 minutes to induct before use. Mix only enough
material which can be used within 3 hours @ 70°F. Higher temperatures will
reduce the pot life, while cooler temperatures will increase the pot life.
Application: For best results, apply 2-3 coats of Pennant Primer to the
substrate. Use a 3/16” -1/4” foam roller made for waterborne paints and a
high-quality synthetic bristle brush.
Apply the primer liberally at 4.5-6.5 wet mils using a foam roller. Follow by
lightly dragging the synthetic brush over the surface to remove bubbles. At
70°F (21°C), the primer can be recoated in 6-8 hours without sanding. The best
results are achieved by recoating without sanding in between coats. This
allows for maximum film build of the primer and reduced labor time. If the
primer requires sanding or has cured more than 72 hours, and with 220-320 grit
paper. The Pennant Primer is sandable in 12-14 hours at 70°F (21°C). Keep in
mind that cooler temperatures will increase the time to recoat, while warmer
temperatures will reduce the time to recoat.
Pennant Primer does not require sanding for adhesion of the Pennant Topside
Paint. If you choose to sand the primer to even out the surface, use 220-320
grit sandpaper.
Note:
- Wet mil thickness gauges are readily available from your local paint store.
Cleanup: Clean the application equipment with warm, soapy water. Brushes
may be further cleaned with denatured alcohol.
Pennant Topside Paint
Note:
- If using a primer other than Pennant Primer, pretesting is recommended to ensure good adhesion is present.
- Pennant Primer does not require sanding for adhesion of the Pennant Topside Paint.
- The crosslinker will remain active in the Pennant Paint for 24 hours. Discard any unused paint after 24 hours.
Mixing: Gently stir Pennant Topside Paint thoroughly to remix any settled
material. While stirring, slowly add the crosslinker at 2 oz. per gallon of
paint. Mix thoroughly to homogenize the paint and crosslinker.
Application: For best results, apply 3 coats of Pennant Topside Paint.
Use a 1/8”–3/16” foam roller made for waterborne paints and a high-quality
synthetic tipping brush. For an improved working time, reduce the paint with
water to 5–10% by volume.
Apply the paint at 3-4 wet mils per coat with a foam roller. Follow by lightly
dragging a quality synthetic bristle brush over the paint to remove bubbles
and even out the surface. Avoid overworking the paint, as this can result in
lap marks.
Larger areas may require additional helpers to maintain the paint’s wet edge.
Let the first coat of paint dry for 4-6 hours before recoating. The Pennant
Topside Paint does not require sanding within 24 hours of application. If the
paint has cured beyond 24 hours, and with 220-320 grit paper. Remove the
sanding dust by flushing the surface with plenty of fresh water. Dry with a
lint-free towel. Apply additional coats of Pennant Topside Paint in the same
manner.
Note:
- Colors such as red, yellow, and orange are more difficult to achieve opacity and may require additional coats.
Cleanup: Clean the application equipment with warm, soapy water. Brushes
may be further cleaned with denatured alcohol.
Conventional Pressure Pot:
Before spraying Pennant Primer and Paint, make sure that the fluid lines are
clean. Purge the lines with denatured alcohol and follow with fresh water.
Application Conditions: When spraying applying Pennant Primer and Topside
Paint, be mindful of the ambient temperature and humidity conditions. Extreme
environmental conditions can negatively affect how the paint flows out once
applied. Best results are achieved in the average temperature and humidity
range of (70-80°F and 5080% relative humidity).
