TotalBoat Epoxy Primers provide excellent finish adhesion & corrosion protection on fiberglass, steel, wood & aluminum. Surfacing Primer is ideal for surfaces that are ready to be topcoated. It ensures adequate filling & lets you build up to 12 mils wet in 3 hrs. High Build Primer has a denser formula to fill pinholes & small surface defects without extensive fairing or applying a surfacing primer over it. Both primers have a simple 1:1 mix ratio, easy application by brush, roller or spray, fast dry times, optimal sanding qualities & can be overcoated with 1- or 2-part urethane coatings.
Primers are available in Gray & Off White. Quart Kits include 1 Qt Base & 1 Qt Activator. Gallon Kits include 1 Gal Base & 1 Gal Activator.
Bonus: Each order includes 2 mixing pots, 2 10 in stir sticks, 2 2 in foam brushes, and 2 paint strainers.

|Epoxy Primer Thinner 200 Data|
|Induction Period: Allow an induction period of approximately 30 minutes prior to reduction and application.|
The recommended thinner is TotalBoat Epoxy Primer Thinner 200 (sold separately) formulated to extend wet film flow, especially when applying primer through a spray nozzle. This reducer can also be used as a surface prep cleaner, and as a solvent for cleaning equipment.
Fiberglass/Wood: Abrade with 100-150 grit sandpaper. Solvent wipe with TotalBoat Epoxy Primer Thinner 200 to remove surface contaminants. Follow with a dry, clean, lint-free cotton rag, and allow to dry completely.
Steel: Sandblast or grind to SSPC-6 Commercial Blast. Remove residue with a vacuum or air hose, solvent wipe with TotalBoat Epoxy Primer Thinner 200, and allow the surface to dry completely.
Aluminum: Sandblast, grind, or sand the surface with 100-150 grit sandpaper, then use TotalBoat Aluminum Boat Etch Wash, as directed. Dry the surface completely and apply TotalBoat 2-Part Epoxy Primer within a maximum of 4 hours.
Previously Primed or Painted Surfaces: Ensure that the substrate is a 2-component system. If no corrosion byproducts are present, abrade the surface with 100-150 grit sandpaper to remove gloss. Wipe away any surface contamination with a lint-free rag wetted with TotalBoat Epoxy Primer Thinner 200. Follow with a clean-dry, lint-free rag to ensure no contaminants were spread or left behind.
Shake or stir the primer base well such that no material is settled on the bottom or sides of the can. Mix 1 part primer base with one part primer activator by volume. Allow an induction period of approximately 30 minutes prior to reduction and application. See Epoxy Primer Thinner 200 data (below) for details on thinning the product, if desired.
Spray Application: SURFACING PRIMER: After induction period, reduce 15-25% with TotalBoat Epoxy Primer Thinner 200 for desired application and film thickness control. Coats can be applied at 3-4 wet mils building up to 12 wet mils thick, waiting 1-3 hours between coats. For single-coat application (3-4 wet mils). it can be sanded after 4 hours. HIGH BUILD PRIMER: After the induction period, for desired application and film thickness control, reduce 15-25% with TotalBoat Epoxy Primer Thinner 200. Apply with a 1.8-2mm spray tip. Coats can be applied at 3-4 mils wet each, building up to 20 wet mils thick, waiting 1-3 hours between coats. For single-coat application (3-4 mils wet), it can be sanded after 4 hours.
Roll/Brushing Application: Thinning should not be needed, but if reduction is desired for flow, use TotalBoat Epoxy Primer Thinner 200. If rolling, use only 1/8-inch nap epoxy/solvent-safe foam rollers. Subsequent coats can be applied every 1-3 hours, up to 12 wet mils thick (Surfacing Primer) or 20 wet mils thick (High Build Primer).
Warning: Do not apply paint materials to surfaces less than 5°F above dew point, or to surfaces warmer than 125°F. Ambient air and surface temperatures should be above 45°F and below 125°F.
