Hot To Apply Pettit Trinidad SR Application Data
The information provided here has been reproduced courtesy of Pettit Paint Company. Wholesale Marine reproduced this information 2/22/2008.
GENERAL DESCRIPTION
Trinidad SR is a hard protective paint which produces the most durable
finish for long lasting performance. The high loading of cuprous oxide combined
with a specially formulated algicide results in unprecedented resistance
to barnacles, algae, slime and other marine and fresh-water fouling
organisms. It can be applied over most hard antifouling coatings. Old soft
antifouling paints must be removed before applying Trinidad SR. Trinidad SR
has excellent adhesion to fiberglass, wood and steel hulls and is perfect for
both power and sail boats. Its compatibility with all properly prepared hard
bottom paints permits safe overcoating without fear of lifting.
APPLICATION INFORMATION
Trinidad SR is heavily loaded with cuprous oxide. As a result of this there is
a tendency for 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.
If possible shake the can of paint on a mechanical paint shaker. Before
using check the sides and bottom of the can to make sure all the pigment
has been mixed in. If mixing is going to be done with a wooden paddle or
an electric drill mixer, pour off half of the liquid from the top of the can into
another can and then properly mix in any settled pigment; then remix the
two parts together thoroughly.
Adhere to all application instructions, precautions, conditions and limitations
to obtain optimum performance. Refer to individual labels and tech
sheets for detailed instructions when using associated products, etc. Do not
thin Trinidad more than 5% (6 ounces per gallon) or inadequate paint film
thickness will occur and premature erosion of the finish will be likely.
SURFACE PREPARATION
Coating performance, in general, is proportional to the degree of surface
preparation. Follow recommendations carefully, avoiding shortcuts.
Inadequate preparation of surfaces will virtually assure inadequate coating
performance.
MAINTENANCE
No antifouling paint can be effective under all conditions of exposure. Man
made pollution and natural occurrences can adversely affect antifouling
paint performance. Extreme hot and cold water temperatures, silt, dirt, oil,
brackish water and even electrolysis can ruin an antifouling paint. Therefore,
we strongly suggest that the bottom of the boat be checked regularly
to make sure it is clean and that no growth is occurring. Lightly scrub the
bottom with a soft brush to remove anything from the antifouling paint
surface. Scrubbing is particularly important with boats that are idle for
extended periods of time. The coating is most effective when the boat is
used periodically.

SYSTEMS
Mix paint thoroughly to insure toxicants are evenly dispersed throughout the can. All surfaces must be clean, dry and properly prepared prior to painting. Do not apply Trinidad SR on aluminum.
Previously Painted Surfaces:
If the previous coating is in good condition, thoroughly sand with 80 grit paper then solvent
clean with 120 Brushing Thinner to remove residue. Apply two finish coats of Trinidad SR. If the previous coating is soft or
in poor condition, remove to the bare surface by sanding or using Pettit 9051 Bio Blast Paint Remover. Proceed with appropriate bare system as described below. Old tin copolymers should be removed or sealed with Pettit 6627 Tie Coat Primer before applying Trinidad SR.
Bare Fiberglass:
All bare fiberglass, regardless of age, should be thoroughly cleaned several times with Pettit 95 Fiberglass
Dewaxer or 120 Brushing Thinner. Sand thoroughly with 80 grit sandpaper to a dull, frosty finish and rewash the
sanded surface with 95 Fiberglass Dewaxer or 120 Brushing Thinner to remove sanding residue. Then apply two coats of
Trinidad SR, following application instructions. Careful observation of the above instructions will help ensure long term
adhesion of this and subsequent years antifouling paint. To eliminate the sanding operation, wash the fiberglass three times using Pettit 95 Dewaxer only. Then apply one coat of Pettit 6999 Sandless Primer. Consult the Sandless Primer label for complete application and antifouling topcoating instructions.
Bare Wood
Sand entire surface with 80 grit paper; wash clean with 120 Brushing Thinner. Apply a coat of Trinidad SR
thinned 25% with 120 Brushing Thinner, allow an overnight dry, lightly sand and wipe clean. Apply two finish coats of
Trinidad SR.
Bare Steel:
Sandblast or disc sand to a clean, bright finish remove residue. Then either immediately apply two coats of
6980 Rustlok Steel Primer, allowing each to dry only 1-2 hours prior to overcoating - OR - immediately apply one thin coat
of 6455 Metal Primer and allow to dry two hours; follow with two coats of 6627 Tie Coat Primer, allowing each to dry two
hours minimum. Apply two finish coats of Trinidad SR.
Keels - Lead:
Abrade surface to bright metal; clean off residue. Apply one thin coat of 6455/044 Metal Primer;
allow to dry two hours. Apply one coat of Pettit 6627 Tie Coat Primer then, if fairing is required, apply Pettit Protect Epoxy
Fairing Compound. Follow with an additional coat of 6627 Tie Coat Primer per label directions. Apply two finish coats of
Trinidad SR.
Keels - Steel or Cast Iron:
Abrade surface to bright metal; clean off residue. Apply one coat of 6980 Rustlok Steel Primer,
allowing to dry only 1 - 2 hours prior to overcoating. Then, if fairing is required, apply Epoxy Fairing Compound followed by
one coat of Pettit 6627 Tie Coat Primer, finish with two finish coats of Trinidad SR.
