Info & Guides



Epoxy Primekote (formerly Epoxy Barrier-Kote) is a multi-purpose two-part epoxy primer that sands freely without loading the sandpaper.

Epoxy Primekote can be used with any topside paint but it is the recommended primer for use with two-part finishes such as Perfection and can also be overcoated with Toplac, Brightside, Interlux Yacht Enamel, Interdeck and Bilgekote. It is also used as part of a system to re-surface cracked and crazed gelcoat prior to the application of topside paint.

Use Epoxy Primekote over clear epoxies as a sanding surfacer and to eliminate the effects of amine blush. Epoxy Primekote is bright white, which makes it ideal for priming bilge and locker areas. When using Epoxy Primekote below the waterline, apply a minimum of 5-6 coats (10 mils minimum). Epoxy Primekote may be applied by brush, roller or spray.

BARE FIBERGLASS: Degrease with Fiberglass Solvent Wash 202 or Fiberglass Surface Prep YMA601. Abrade with 120-220 grade (grit) paper. Remove sanding residue.

CLEAR EPOXY: Allow three to seven days for clear epoxies to cure fully. Remove amine blush by using Fiberglass Surface Prep YMA601. Sanding does not remove contamination. Rinse with fresh water and allow to dry. Abrade with 80-120 grade (grit) paper. Remove sanding residue. Sand with 80 grade (grit) sandpaper and remove sanding residue with Brushing Reducer 2333N. Repair any defects with Interfill Watertite Epoxy Filler, then sand with 120-220 grade (grit) paper and remove sanding residue.

BARE METAL: Surface should be blasted to bright metal. If blasting is not possible, grind with 36 grade (grit) discs. Apply one coat of Interprotect 2000E that has been thinned 10-15% with Reducing Solvent 2316N. Follow overcoating times for InterProtect 2000E and then apply Epoxy Primekote.

BARE WOOD: Sand surface with 80-120 grade (grit) paper and wipe clean.
