General Purpose Chlorinated Rubber Primer
This Primer is a general purpose chlorinated rubber type product used as a primer on metal surfaces and as a tie coat between different types of coatings. This versatile product can be used successfully above and below the waterline as a primer and over a variety of coatings as a tie coat. When used over Metal Primer it forms an excellent, easy to use system for use on all underwater running gear. It is compatible with all antifouling bottom paints and with Easypoxy, vinyl alkyds and conventional alkyds. This Primer can also be used on new and bare wood on boat bottoms to seal the wood before applying an antifouling paint.
Shake or stir the This Primer thoroughly. Apply by brush, roller or spray. Thinning is not normally required for brush or roller application, however, small amounts of Recommended 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.
• Can be used as a metal primer or as a tie coat.
• Recommended above and below the waterline.
• Compatible with all antifouling bottom paints as well
as all single component topside paints.
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.

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 This Primer to seal the tin copolymer bottom paint. Allow This Primer to dry 4 hours .
Bare Aluminum Hulls or Outdrives: Abrade to clean, bright metal by sandblasting, sanding or wire brushing. Blow off or vacuum sanding residue and immediately apply one thin coat of Metal Primer. Let dry two hours and apply two coats of This 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. . Always read the labels or technical data sheets for all products specified herein before using.
NOTE: Non-aluminum metal parts or hulls can be coated with any antifoulings except II. Aluminum surfaces should be coated with II antifouling only. 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 Metal Primer and allow to dry two hours; follow with two coats of This 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 1 Brushing Thinner. Apply a coat of This Primer thinned 25% with Recommended Epoxy Thinner, allow an overnight dry, lightly sand and wipe clean.
Antifouling Bottom Paint: All antifouling bottom paints may be applied directly over This Primer. Allow the This Primer the proper drying time prior to applying antifouling paint.
