Addressing Osmotic Blistering
What’s the best way to deal with osmotic blistering?
Osmotic blistering is a common problem for fiberglass hulls, caused by moisture penetration and subsequent chemical reactions. To prevent this issue, it’s crucial to maintain a proper barrier between the hull and the water. This can be achieved by applying an epoxy barrier coat or using a high-quality bottom paint designed to prevent osmotic blistering.If your hull is already experiencing osmotic blistering, the affected areas will need to be ground out, dried thoroughly, and treated with a barrier coat before refinishing. This process can be time-consuming and labor-intensive, often requiring the expertise of a professional repair facility.

Repairing Wooden Hulls
How can I repair damage to a wooden hull?
Wooden hulls require special care and attention. For minor holes or cracks, you can use a two-part epoxy filler or a marine-grade wood filler. Larger damages may require replacing the affected planks or sections of the hull, a process known as “sistering.”It’s essential to follow proper techniques and use materials specifically designed for marine applications.
