APPLICATION INFORMATION
Shake or stir the 6627 Tie Coat Primer thoroughly. Apply by brush, roller or spray. Thinning is not normally required for brush or roller application, however, small amounts of 97 Epoxy Thinner may be used if necessary to facilitate application. For spraying, use 97 Epoxy Thinner at levels of 5-10% by volume to ensure a smooth finish with minimal orange peel. Wet film thickness unthinned should be 5.7 to 7.1 mils per coat, which yields 2.0 to 2.5 mils dry film thickness.

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.

SYSTEMS
Previously Painted Fiberglass Surfaces (Old Tin Copolymers): The surface to be painted must be dry, clean and free of any contamination or foreign matter. High pressure wash, scrub, then sand the old bottom paint with 80 grit sandpaper. Apply one coat of 6627 Tie-Coat Primer to seal the tin copolymer bottom paint. Allow 6627 Tie Coat Primer to dry 4 hours and apply antifouling paint.

Bare Aluminum Hulls or Outdrives: Clean surface to be painted with coarse scotchbrite pads and Pettit 95 Dewaxer. Abrade to clean, bright metal by sandblasting, sanding or wire brushing. Blow off or vacuum sanding residue and immediately apply one thin coat of Pettit 6455/044 Metal Primer. Let dry two hours and apply two coats of Pettit 6627 Tie Coat Primer, allowing the proper dry time between coats (see dry time chart) before sanding lightly with 80 grit sandpaper and applying appropriate antifouling paint. This is a simplified system for smaller vessels. Please consult your Pettit representative or the Pettit Technical Department for more complex, professional systems. Always read the labels or technical data sheets for all products specified herein before using.
NOTE: Do not use copper or cuprous oxide based antifouling coatings on aluminum.

Bare Steel: Sandblast or disc sand to a clean, bright finish then remove residue. Immediately apply one thin coat of 6455/044 Metal Primer and allow to dry two hours; follow with two coats of 6627 Tie Coat Primer, allowing the proper dry time between coats (see dry time chart). Apply finish coats.
Stainless Steel, Trim Tabs and Bronze Throughhulls: Follow the “Bare Aluminum Hulls or Outdrives” system above.

Bare Wood: Sand entire surface with 80 grit paper; wash clean with 120 Brushing Thinner. Apply a coat of 6627 Tie Coat Primer thinned 25% with 97 Epoxy Thinner, allow an overnight dry, lightly sand and wipe clean.

TOPCOATS

Antifouling Bottom Paint: All Pettit antifouling bottom paints may be applied directly over 6627 Tie Coat Primer. Allow the 6627 Tie Coat Primer the proper drying time prior to applying antifouling paint.
Topside Finishes: All Pettit, Z*Spar, and Shipendec topside finishes are compatible with 6627 Tie Coat Primer. If the surface is sufficiently smooth, any Pettit, Z*Spar, or Shipendec topside product may be applied directly over 6627. If the surface needs additional smoothing, use Pettit 6149 EZ Primer as a base over the 6627.
