Trinidad 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
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 10 percent (12 ounces per gallon) or inadequate paint film thickness will
occur and premature erosion of the finish will be likely.
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.
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 several times a
month 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.
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 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. If the previous coating is soft or in poor condition, remove to the bare surface by sanding or using Pettit 9050 Bottom 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.
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, 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 thinned 25 percent with 120 Brushing Thinner, allow an overnight dry, lightly sand and wipe clean. Apply two finish coats of Trinidad.
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 6462 Q.D. Zinc Chromate Primer, allowing each to dry two hours minimum. Apply two finish coats of Trinidad.
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 7000/7001 Epoxy Fairing Compound. Follow with an additional coat of 6627 Tie Coat Primer per label
directions. Apply two finish coats of Trinidad.
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 7000/70001 Epoxy Fairing Compound followed by one coat of Pettit 6627 Tie Coat Primer, finish with two finish coats of Trinidad.
This is a simplified system for smaller areas designed for good performance and easy application by the boatyard professional or do-it-yourselfer. For larger vessels or for applications where a high performance, professional system is desired, please consult your local Pettit representative or the Pettit Technical Department.
