Reduces water absorption in fiberglass hulls. Prevents osmotic blistering.
Heavy duty high build two-component epoxy-polyimide coating. Use where maximum
resistance to fresh or salt water is required. Complete coating system is
resistant to water many industrial fumes and very humid conditions. Excellent
durability.
The last step in the gelcoat blister repair system is the application of the
final barrier, Pettit 4700/4701 High Build Epoxy Primer over the sealed and
faired fiberglass laminate. For prevention of osmosis on new or unblistered
hulls, the removal of the gelcoat, sealing and fairing is not required, and
therefore application of the High Build Epoxy Primer is the first step.
Regardless of which system you require, the application of the final epoxy
barrier will be the same. Multiple coats are required (usually 2 or 3) until a
dry film thickness of 18 mils (eighteen thousandths of an inch) is reached. Each
coat may be applied in succession after the preceding coat has cured to a gel
stage. After the final coat has reached the gel stage, the antifouling paint may
be applied. Following this procedure will eliminate the need for sanding between
coats, greatly reducing time and labor.
