- 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. Suggested spray application equipment:
Conventional Spray: Binks - No. 29 or No. 62 Gun, 66 Fluid Tip & 66 PB Air Cap or DeVilbiss - JGA 502 Gun, E Fluid Tip & 78 Air Cap. Airless Spray: Graco 28-1 Pump with 817-819 Tip. -
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.

Reviews for Pettit Tie Coat Primer 6627
I used this tie coat primer over a sanded and prepped fiberglass canoe hull. It worked well under an automotive-paint finish (above water line) and gave surprisingly good results under Pettit Vivid anti-fouling bottom paint (below water line. Overkill for an old fiberglass canoe? Perhaps, but I was practicing for replacing the bottom paint on my 1984 sailboat.
