GENERAL DESCRIPTION
Ultima PRO Ablative Dual Biocide Bottom Paint is an antifouling protective coating resistant to slime, algae, barnacles and other marine fouling. The high loading of cuprous oxide combined with an organic algicide offer unpredendented control over all types of fouling even in the most severe fouling areas. Ultima PRO's unique controlled erosion minimizes coating build up and keeps underwater surfaces smooth and clean.

APPLICATION INFORMATION
Ultima PRO is heavily loaded with cuprous oxide. As a result of this loading 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 Ultima PRO more than 10% (12 ounces per gallon) or inadequate paint film thickness will occur and premature erosion of the finish will be likely. Do not apply Ultima PRO in thick films or in more than four coats as poor adhesion may result. When applying by roller use a short nap (3/16 inch maximum) roller cover.

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 selfcleaning nature of the coating is most effective when the boat is used periodically.

SYSTEMS

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 PRO 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 185 Ablative Thinner to remove residue. Apply two finish coats of Ultima PRO. If the previous coating is soft or in poor condition, remove to the bare surface by sanding or using a paint & varnish 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 PRO.

Bare Fiberglass: All bare fiberglass, regardless of age, should be thoroughly cleaned several times with Pettit 95 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 Ultima PRO, 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. Apply two or three coats of Ultima PRO.

Barrier Coat: Fiberglass bottoms potentially can form osmotic blisters within the gelcoat and into the laminate. To render the bottom as water impermeable as possible, prepare the fiberglass surface as mentioned above (sanding method) then apply three coats of Pettit Protect 4700/4701 High Build Epoxy Primer per label directions. Apply two or three finish coats of Ultima PRO.

Bare Wood: Sand entire surface with 80 grit paper; wash clean with 185 Ablative Thinner. Apply a coat of Ultima PRO thinned 25% with 185 Ablative Thinner, allow an overnight dry, lightly sand and wipe clean. Apply two finish coats of Ultima PRO unthinned.

Bare Steel*: Sandblast or disc sand to a clean, bright finish and remove residue with clean, dry compressed air or a clean brush. Immediately apply two coats of Pettit Protect 4700/4701 High Build Epoxy Primer. Read and follow carefully the instructions on the 4700/4701 Epoxy Primer label. If the surface to be painted will be prepared using hand tools such as wire wheels or sanders, clean-off residue and immediately apply one coat of Pettit 6980 Rustlok Steel Primer. Let dry 1-2 hours and follow with two coats of 4700/4701 High Build Epoxy Primer. Read and follow carefully the instructions for application and topcoating on both primer labels. Apply two or three finish coats of Ultima PRO.

Keels - Lead: Abrade surface to bright metal; clean off residue. Apply one thin coat of 6455/044 Metal Primer; allow to dry six hours. Apply one coat of 4700/4701 High Build Epoxy Primer then, if fairing is required, apply Pettit Protect 7000/7001 Epoxy Fairing Compound. Follow with an additional coat of 4700/4701 High Build Epoxy Primer per label directions. Apply two or three finish coats of Ultima PRO.

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 7000/7001 Epoxy Fairing Compound followed by one coat of 4700/4701 High Build Epoxy Primer, finish with two or three coats of Ultima PRO.

Underwater Gear - Stainless Steel and Bronze: Use the same system as for lead keels.
