*The above dry times are minimums. Ultima SSA may be recoated after the minimum time shown. There is no maximum dry time before launching.

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 Ultima SSA. 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 must be removed or sealed with 6627 Tie-Coat Primer before applying Ultima SSA. When sanding old bottom paint, always wet sand and take precautions against getting the material in your eyes, nostrils, open cuts, etc.

BARE FIBERGLASS: All bare fiberglass, regardless of age, should be thoroughly cleaned with 92 Bio-Blue Hull Surface Prep or de-waxed several times with Pettit D-95 Dewaxer or 120 Brushing Thinner. Sand thoroughly with 80 grit sandpaper to a dull, frosty finish and rewash the sanded surface with 120 Brushing Thinner to remove sanding residue. Then apply two coats of Ultima SSA, 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, prep the surface with 92 Bio-Blue Hull Surface Prep or wash the fiberglass three times using Pettit 95 Dewaxer only. Then apply one thin coat of Pettit 6998 Skip-Sand Primer or 6999 Sandless Primer. Use a 3/16” or less nap when applying by roller. When applying Ultima SSA over 6999 Sandless Primer, apply one coat of a hard modified epoxy antifouling paint such as Unepoxy Standard or Trinidad after the Sandless Primer is ready for top coating; then apply Ultima SSA over the hard modified epoxy. Consult the primer label for complete application and antifouling top coating instructions. Apply two or three coats of Ultima SSA.

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 SSA.

BLISTERED FIBERGLASS: See Pettit Technical Bulletin TB-1000 Gelcoat Blister Repair and Prevention Specification for detailed instructions.

BARE WOOD: Sand entire surface with 80 grit paper; wash clean with 120 Brushing Thinner. Apply a coat of Ultima SSA thinned 25% with 120 Brushing Thinner, allow an overnight dry, lightly sand and wipe clean. Apply two finish coats of Ultima SSA. Any metal parts must be primed before applying the bottom paint.

STEEL HULLS: 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 SSA.

KEELS - LEAD: Abrade surface to bright metal; wipe clean using Pettit 120 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 SSA.

KEELS - STEEL OR CAST IRON: Abrade surface to bright metal; wipe clean using Pettit 120 Brushing Thinner. Apply one coat of 6980 Rustlok Steel Primer, allowing to dry only 1 - 2 hours prior to over coating. 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 SSA.

DO NOT USE THIS PRODUCT ON ALUMINUM HULLS AND OUTDRIVES.

APPLICATION INFORMATION: Ultima SSA contains 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 settle 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 SSA more than 10% (12 ounces per gallon) or inadequate paint film thickness will occur and premature erosion of the finish will be likely.
