.PRODUCT APPLICATION .
SURFACE PREPARATION
All surfaces must be free of dirt, loose paint, oil, grease,
wax, soap and any other foreign matter. Surfaces should
be properly prepared by sanding before any primers or
paints are applied. When sanding old antifouling paint,
wear proper respirator to prevent the inhalation of sanding
dust.
BARE FIBERGLASS – All bare fiberglass, regardless of
age, must be thoroughly cleaned several times with a
fiberglass cleaner to remove all traces of mold release
agents and wax. Sand thoroughly with 80 grit sandpaper
to create a dull, frosty appearance. Remove sanding dust.
Apply two coats of Boat Bottom Antifouling Paint
according to the application instructions in the next column.
BARE WOOD – Sand the surface smooth with 80 grit
sandpaper. Wipe the surface to remove sanding dust and
residue. Apply a coat of Marine Coatings Boat Bottom
Antifouling Paint thinned with 25% mineral spirits and
allow to dry overnight. Lightly sand and remove sanding
dust. Apply two finish coats of Boat Bottom Antifouling
Paint.
PREVIOUSLY PAINTED SURFACES – If the previous
coating is in good condition, thoroughly sand with 80 grit
sandpaper. Remove sanding dust. Apply two finish coats
of Boat Bottom Antifouling Paint. If the previous coating is
soft or in poor condition, remove by sanding. Old tin
copolymers should be removed or sealed with a tie coat
primer before applying this product.
PRODUCT APPLICATION (cont.) .
APPLICATION
Apply when air (ambient) temperature is between 50-90°F
(10-32°C) and the relative humidity is below 85%. Do not
apply on extremely humid days (90% humidity or above)
or when rain is threatening. Do not apply in the late
afternoon outdoors as the wet film may be adversely
affected by dew. When working in cooler temperatures, be
sure the air and surface temperatures will remain at or
above 50°F for at least 8 hours after application.
This product contains a high percentage of cuprous oxide.
Which may cause settling to occur especially if the paint
has been on the shelf for several months. It is necessary
to thoroughly mix the paint before using to ensure any
settled pigment is re-dispersed. If possible shake the
container on a mechanical paint shaker or use an electric
power drill mixer. Before suing check the sides and bottom
of the can to ensure any settled pigment has been re-
dispersed. It may be necessary to pour off half of the liquid
from the top of the can into another can to properly mix in
any settled pigment. Then remix the two parts together
thoroughly.
This product can be applied by brush, roller or spray under
good drying conditions. Two coats should be applied for
best antifouling protection.
THINNING
Thinning this product is not normally required. If necessary
use mineral spirits to create a smoother finish on warm
and breezy days.
DRY & RECOAT
Dry and recoat times are based on 70°F and 50% relative
humidity. Allow more time at cooler temperatures.
Antifouling Paint can be recoated after 4 hours. Boats can
be launched after 16 hours. Full cure is achieved at 72
hours.
CLEAN-UP
Clean up application tools and equipment with xylene.
MAINTENANCE
Pollution and natural occurrences can adversely affect
antifouling paint performance. Extreme hot and cold water
temperatures, silt, dirt, oil, brackish water and electrolysis
can damage antifouling paint. Check the boat bottom
monthly to make sure it is clean and no growth is visible.
Lightly scrub the boat bottom with a soft brush to remove
foreign material from the surface.
