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.
