Checking Your Hull Paint

Checking Your Hull Paint

If you are considering buying a boat lift for your boat and you have been storing your boat submerged in the water at a dock, your hull could be in need of a new paint job or at least a little bit of a face lift! Storing a boat in water can cause blisters to form on your hull because the materials used on the outer coating of the hull is not completely impermeable to water. Simply storing your boat in water is not the only cause of hull blisters, many factors influence the tendency for a hull to blister. These include poor manufacturing and lay‐up technique, under or over‐catalyzation of polyester resin, and water soluble contaminants in the laminate applied. Any of these issues can cause water to adhere to nature and follow osmotic pressure creating small bubbles on the hull. Boats kept in warmer water also seems to cause more blisters to develop.

When you invest in a boat lift you will want to make sure that your hull is in tip top shape! We’re going to go over a High Build Epoxy Primer Method that is a heavy duty two-part epoxy coating that reduces the chance of water absorption. Follow these steps:

  • Clean and de-wax your hull using 92 Bio-Blue Hull Surface Prep, D-95 Dewaxer, or 120 Brushing Thinner
  • Apply at least three coats of Pettit Protect Hi-Build Epoxy Primer, it is recommended that you have 12 mils of thickness for metal and fiberglass hulls
  • Finish with two coats of Pettit antifouling bottom paint
  • Let dry and enjoy the fresh new paint job!
