Ultima Single Season Ablative contains cuprous oxide, therefore, settling will occur. Thoroughly mix the paint before using, and 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 to obtain optimum performance. Do not thin Ultima Single Season Ablative more than 10 percent (12 ounces per gallon) or inadequate paint film thickness will occur and premature erosion of the finish will be likely.
Surface preparation is crucial to coating performance. 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 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.
Mix paint thoroughly to ensure toxicants are evenly dispersed throughout the can. All surfaces must be clean, dry and properly prepared prior to painting. Do not apply Ultima Single Season Ablative on aluminum hulls or outdrives.
Previously Painted Surfaces:
If the previous coating is in good condition, thoroughly sand with 80 grit paper then solvent clean with 120/T-10 Brushing Thinner to remove residue. Apply two finish coats of Ultima Single Season Ablative. If the previous coating is soft or in poor condition, remove old coat to the bare surface by sanding or using Pettit 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 Ultima Single Season Ablative Antifouling Paint. When sanding old bottom paint, always wet sand and take precautions against getting the material in your eyes, nostrils, open cuts, etc.
All bare fiberglass, regardless of age, should be thoroughly washed with soap, ammonia and water. Let dry, then clean several times with Pettit 95 Fiberglass Dewaxer. Sand thoroughly with 80 grit sandpaper to a dull, frosty finish and rewash the sanded surface with 95 Fiberglass Dewaxer to remove sanding residue. Then apply two coats of Ultima Single Season Ablative, 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 Fiberglass Dewaxer only. Then apply one coat of Pettit 6999 Sandless Primer. After the Sandless Primer is ready for topcoating apply one coat of a hard modified epoxy antifouling paint such as Unepoxy Standard or Trinidad; then apply Ultima Single Season Ablative over the hard modified epoxy. Consult the Sandless Primer and hard modified epoxy antifouling paint labels for complete application and antifouling topcoating instructions.
See Pettit Blister Repair Technical Sheet for detailed instructions.
Sand entire surface with 80 grit paper; wash clean with 120/T-10 Brushing Thinner. Apply a coat of Ultima Single Season Ablative thinned 25% with 120/T-10 Brushing Thinner, allow an overnight dry, lightly sand and wipe clean. Apply two finish coats of Ultima Single Season Ablative. Any metal parts must be primed before applying the bottom paint.
Sandblast to SSPC-SP 6 'Commercial' blast, blow off residue with clean, compressed air, and immediately apply three coats Pettit Protect 4700/4701 following application and recoat instructions. Alternatively, hand sand with 80 grit sandpaper or power hand tool clean, then remove residue with clean compressed air or clean, solvent dampened rags. Immediately apply one coat of Pettit 6980 Rustlok Steel Primer and let dry to a tack free state (usually 30 minutes to 2 hours, dependent on temperature). Then apply two coats of 4700/4701 High Build Epoxy Primer following application and recoat instructions. Apply two coats of Ultima Single Season Ablative.
Keels - Lead:
Abrade surface to bright metal; wipe clean using Pettit 120/T-10 Brushing Thinner. Apply one thin coat of 6455/044 Metal Primer; allow to dry two hours. Apply one coat of Pettit 6627 Tie Coat Primer. Follow with an additional coat of 6627 Tie Coat Primer per label directions. Apply two finish coats of Ultima Single Season Ablative.
Keels - Steel or Cast Iron:
Abrade surface to bright metal; wipe clean using Pettit 120/T-10 Brushing Thinner. 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. Apply two finish coats of Ultima Single Season Ablative.
