Prekote® is a unique V.O.C. compliant, single package, under coater for use with Brightside® Polyurethane, Toplac, Yacht Enamels or any one-part topside finish. Microspheres are used to give Prekote® superior build and hide while improving flow and sandability. Prekote® is recommended anywhere above the true waterline where a coating is needed to provide a smooth, fair surface for overcoating with a topside enamel.

Prekote® is available in both White (4279) and Gray (4280). The use of Prekote® Gray 4280 is recommended for use under dark colors. White (4279) and Gray (4280) may be blended for use under intermediate colors.

Do Not Use INTERTHANE PLUS 2300 Series Polyurethane or any two-part catalyzed product over Prekote ®. Prekote must be sanded prior to overcoating with one-part topside finish

Part No.

Preparation PREVIOUSLY PAINTED SURFACES: Sand old surfaces with 120 grade (grit) paper. Remove sanding residue. Wipe with Brushing Liquid 333. Repair surface defects with Surfacing Putty 257. Sand surface, wipe clean.
BARE WOOD: Sand with 80 grade (grit) paper. Wipe with Brushing Liquid 333. Repair surface defects with Surfacing Putty 257. PLYWOOD: Follow directions for bare wood. Apply Inter-Prime Wood Sealer Clear 1026. MAHOGANY Follow directions for bare wood. Apply Pre-Kote directly to the wood.
BARE FIBERGLASS: Wipe a small area with a clean rag that has been wetted with Fiberglass Solvent Wash 202. While the surface is still wet, wipe with a clean, dry rag. Continue this process until the entire surface has been cleaned. Sand with 80 grade (grit) paper. Wipe with Fiberglass Solvent Wash 202. Repair surface defects with Interfill Epoxy Filler. Sand surface, wipe clean.

Method Apply 1-2 coats. Depending on surface condition. Allow the necessary overcoating time between applications. Sand between primer coats with 120 grade (grit) paper until translucent. Remove sanding residue with a rag dampened with Brushing Liquid 333. Apply finish coats. Sand with 220 grade (grit) paper between Pre-Kote and finish enamel.

Hints Thinner Brush - Brushing Liquid 333. Spray - Special Thinner 216.
Cleaner Painted Surfaces - Brushing Liquid 333. Bare Wood - Brushing Liquid 333. Bare Fiberglass - Fiberglass Solvent Wash 202.
Ventilation and Humidity Control It is best to paint on warm, dry mornings.
Airless Spray Pressure: 170-204 bar/2500-3000 psi. Tip Size: 0.48-0.53 mm/19-21 thou.
Conventional Spray Pressure Pot: Pressure: 3.44-4.08 bar/50-60 psi (gun pressure). Pot pressure (6 ft hose) 8-10 psi. Tip Size: 0.89-1.4 mm/35-50 thou. Siphon Cup: Pressure: 3.44-4.47 bar/50-65 psi - gun pressure. Tip Size: 1.8-2.2 mm/70-85 thou.
Other Spray pressures listed are recommendations only. The applicator may use any settings which yield the best results for the individual spraying technique and current weather conditions. It is always good painting practice to apply the finish enamel soon after sanding to avoid surface contamination. Always apply at least one coat of Pre-Kote over area treated with Surfacing Putty 257 to seal the putty and eliminate shadows.

Some Important Points Pre-Kote is a high solids primer. Avoid a heavy application as this may lead to solvent entrapment. Product temperature should be minimum 10°C/50°F and maximum 29°C/85°F. Ambient temperature should be minimum 10°C/50°F and maximum 35°C/95°F. Substrate temperature should be minimum 10°C/50°F and maximum 29°C/85°F.

Compatibility/Substrates Apply to clean, dry, properly prepared surfaces only. Do not apply over clear epoxy such as Epiglass Epoxy.
