Product Overview

The high-solids formula of Interprotect HS results in fewer coats required to reach the desired film thickness.

Featuring a high-solids formula that is low-in-VOCs, InterProtect® HS is a two-part epoxy that can be used above or below the waterline as a high-build primer. The high-solids formulation results in fewer coats required to reach the desired film thickness. As part of a gelcoat blister repair or prevention system, the formula incorporates Micro-Plate® Technology to reduce water migration through the epoxy to the hull surface which could lead to blistering. Micro-Plates® also provide corrosion protection for metals. Kit makes one gallon.
