For use in prevention of and repair of osmotic blistering
Two-part epoxy water barrier with Micro-Plates
Up to two weeks is allowed between coats of InterProtect 2000E
Fast drying, easy application
Sag resistance to insure the elimination of sags and runs during application
InterProtect® 2000E is a unique two-part epoxy designed to reduce the potential of water absorption by fiberglass hulls. InterProtect is unique among epoxies because it has Micro-Plates®, a protective barrier within its film to slow down water permeation. 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.
InterProtect has been the product of choice for Boat Builders and Repair Yards since 1985.
Prevention is Better Than Cure The importance of having a moisture-free hull cannot be overemphasized. The drier the laminate, the lighter the hull, the better the performance, the more efficient fuel use and the longer the gelcoat life. A boat hull that has absorbed moisture will also sit lower in the water than intended and will reduce the responsiveness of the boat.
The InterProtect® System was designed to repair hulls which have experienced gelcoat blistering. However, the best time to attack hull blistering is before it happens.
Taking preventative action before a problem occurs will greatly reduce the likelihood of an expensive repair and increase resale value. If you're buying a new boat, protect your investment with the InterProtect® System before it ever goes in the water!

Important Steps in the Repair of Gelcoat Blisters
Proper Preparation of the Gelcoat This includes getting all of the antifouling paint off and removal of as much gelcoat as necessary to get the hull dry (i.e. the entire gelcoat or just small areas). A professional, who has looked at your boat, should make this determination.
Drying of the Hull This is the most critical step in the process. If you do not get the hull dry it will re-blister. We recommend a comprehensive washing and drying procedure.
Application of Epiglass® HT9000 Resin This solventless epoxy seals up the laminate and fills any cloth that has been voided of resin. This should be done before using fillers to fill the voids.
Application of Interprotect® 2000E or Interprotect® 3000 These epoxies are used as a water barrier to minimize the possibility of reoccurrence of damage.
Recommended Overcoating Intervals
Time Between Coats of Interprotect® 2000E**
First Coating of Antifouling
Number of Coats*
*It usually takes 4-5 coats of InterProtect® 2000E/2001E but the final film thickness of 10 mils D.F.T. is more important than the number of coats. See page 28 for amount needed.
**If you exceed the maximum dry times between coats of epoxy you must sand with 80 grit and apply at least one more coat of InterProtect® 2000E/2001E to ensure having 10 mils D.F.T.
***Overcoating times will vary due to wide variations in temperature and humidity. The best method to determine when the InterProtect® 2000E is Ready-to-Overcoat is to check the paint film using the 'Thumb Print' test. If the InterProtect® 2000E feels tacky and you can leave a thumbprint in the paint film without getting any paint on your thumb it is ready for overcoating. Test the paint film 1 hour after starting the application. Continue testing every 15 minutes using the 'Thumb Print' test until reaching the ready-to-overcoat stage. Immediately, begin to apply the Interlux® antifouling paint once the primer has reached the Ready-To-Overcoat stage. Do not use this method with Epiglass® Epoxy or InterProtect® 3000. These times do not apply to VC® Offshore or Baltoplate, Micron® Optima or Fiberglass Bottomkote® Aqua.
How much InterProtect® 2000E/2001E do I need?
It is the best to actually measure the wetted surface area of the hull. If this is difficult to do, a close approximation can be made by multiplying the length overall, times the beam, times 85% (L.O.A. x Beam x .85 = wetted surface area). Divide the wetted surface area by 60 for brush and roller applications and by 45 for spray application. The resulting number is the number of gallons that need to be applied to reach a 10 mil dry film thickness.

My name is Gary Alderman. I am third-generation owner of Snead Island Boat Works in Palmetto Florida. We have used Interprotect 2000 for probably the last 25 years. It’s a great product, I highly recommend it. In fact we use it from the keel to the masthead and plain and simple is that it works. We have no comebacks with that product. We use it not only for blister repairs, it’s great for aluminum fuel tanks, it’s great for anything we use that we need to epoxy prime before.
Is this the produt the kit that contains epoxy and accelerator?
