Interlux InterProtect 2000E Barrier Coat Epoxy Primer

InterProtect 2000E is a two-part self priming epoxy designed to protect fiberglass boat hulls from water absorption and reduce the likelihood of gelcoat blisters.

Interlux's Micro-Plate formula creates an effective barrier against water permeation. 2000E may be used above and below the waterline as a universal primer for all surfaces. It is also an excellent primer for all metals and can be used as part of a no sand system.

2.25 Gallon containers do not include 2001E Cure. Each 2.25 Gallon container requires the separate purchase of one INT-Y2001EG

InterProtect Primer Features:

  • Two-part epoxy water barrier with Micro-Plates
  • Up to two weeks is allowed between coats of 2000E
  • Now available in two colors, Gray and White
  • Fast drying, easy application
  • Sag resistance to insure the elimination of sags and runs during application

    Technically, InterProtect Micro-Plates provide millions of overlapping microscopic plates that create a barrier similar to shingles on a roof. These overlapping Micro-Plates eliminate any direct path for water migration and also improve the sag resistance of the epoxy making application easier.

    What is Gelcoat Blistering?

    Osmosis is caused by a chemical reaction between water and unreacted substances remaining in the manufactured hull. Water breaches the exterior gelcoat and reacts with the chemical components creating acidic substances. These substances create pressure behind the gelcoat which causes blisters and eventually cracking. Once the gelcoat is breached in this manner, the underlying laminate is capable of absorbing water like a sponge.

    Use the Interlux InterProtect system to treat and help prevent this serious problem.

    This formula helps you calculate how much paint is necessary for wetted surface area (i.e. under antifoulant paint). Calculate surface area as follows: Wetted Surface Area (WSA) = LOA x Beam x 0.85, then divide the WSA by 60 when brushing/rollering or 45 when spraying to determine the number of gallons necessary to reach 10 mils. For complete hull coverage calculate total surface area to be covered, then follow the division step.

    I used this barrier coat years ago and bought another quart

    I used this barrier coat years ago and bought another quart to fix a patch. Great stuff, easy to mix and use!

    Strong stuff

    I brushed on 5 coats, just on the very bottom of an 18' sailboat. A gallon was more than enough.If there's a next time, I'll use thinner to ease up the brushing as this stuff is thick and dries quickly, leaving obvious brushstrokes.It sands nicely though, which I did between the last 3 coats. Smells very strong, fumes are dizzying - good ventilation and/or a respirator is essential. Sticks well, builds up quick, seems like it'll last forever.Very confident in this product.

    I used this on bare aluminum sanded with 80 grit paper. I applied it easily then was amazed at the hard, well-bonded coating. I then sanded with 220 grit the next morning and applied the finish paint.

    Have used on a 50 year old Wayfarer sailboat and this product gives her good protection from moisture and sands well for a fast bottom.

    I used 2000e on a world cat that had been previously bottom painted. I soda blasted the bottom, then applied 2000e for an aesthetically pleasing look since I no longer want bottom paint on the boat. I've rolled it and sprayed it. It works well both ways, but if you have the option I would spray it, especially if you are doing large areas. This is a very durable product that dries quickly and sands nicely. FYI: I sanded it slick to attain better fuel mileage, but it didn't help the economy, so I would recommend applying it and letting it dry. Happy boating!

    I had hundreds of small osmosis holes in a 30yo 8 metre fibre glass yacht hull. I took all old paint and anti foul off. Sanded. I cleaned hull and washed it every other day with clean water for a month. I let it dry for a month. I filled holes with interprotect. Sanded. Filled holes with interprotect. Sanded. Put on four or five coats of interprotect. Put on two coats of anti foul. When it came out eight months later hull was perfect. Now working on iron hull, starting in at two inches at bottom with rust.

    Nice stuff, easy coverage

    Coating over epiglass on my blistered sailboat hull. I found this to go on easy. The grey over white coats and vice versa made full coverage easy. Tossed the roller covers and brushes after each coat. But acetone cleaned up other stuff well, probably could have saved a few brushes.
