Pettit Protect® 47004701CAG High Build Epoxy Primer (Gray Qt. Kit) is a heavy-duty, two-component epoxy primer designed to provide maximum resistance to fresh and salt water. Its high-solids barrier helps reduce water absorption to support osmotic blister prevention and repair, while delivering dependable corrosion protection on underwater metals. Like most epoxies, it should be topcoated to eliminate chalking.

Parts Desk Insights
Best Use Case: Best suited as the epoxy barrier/primer layer in a marine bottom coating system—particularly when the goal is reducing water absorption to help prevent osmotic blistering and to improve corrosion protection on underwater metals.
Common Issues: Common install problems with marine epoxies include inadequate surface preparation and skipping the required topcoat step (epoxies can chalk if left un-topcoated). For best results, confirm the recommended cure/recoat timing for your conditions and follow the manufacturer application guide for mixing and coat thickness/build.
