Two-Part Epoxy Barrier Coat for Osmotic Blister Prevention and Repair — Gallon Kit, Case of 2.
Interlux Interprotect 2000E is a two-part epoxy barrier coat primer that protects fiberglass hulls from water absorption and osmotic blistering. Formulated with Interlux's proprietary Microplates® technology, the cured film creates an overlapping platelet structure that dramatically reduces water vapor transmission through the hull — providing superior barrier protection compared to conventional epoxy primers.
Interprotect 2000E is also the recommended product for repairing fiberglass hulls that have already experienced osmotic blistering, providing a durable, water-resistant base coat before antifouling paint application. Sold as a case of 2 gallon kits, each kit includes the base and curing agent. Long overcoating windows add flexibility for multi-coat application schedules.

Parts Desk Insights
Interprotect 2000E is the standard of care for osmotic blister prevention and repair on fiberglass hulls — if you're hauling a boat that has blistered, or doing a full bottom job on a fiberglass hull that's never had a proper barrier coat, this is the product to use. Apply a minimum of 3–5 coats for effective barrier protection; the long overcoating window means you can apply multiple coats in a single day without waiting for full cure between coats. The case-of-2 format is practical for full hull applications on boats over 30 feet where a single gallon kit won't cover the entire bottom.
