Gel Coat Blisters

Have a fiberglass hull? Gatorbak may be able to help save it!

What are gelcoat blisters?

Gelcoat blisters are able to form because the gelcoats on fiberglass boats are not completely water proof. The water can get behind the gelcoat and come into contact with the deeper layers of your boat hull. If the water comes into contact with something in the deeper layers of the hull (any tiny object such as dust) it is too big to go back through the gelcoat. When the water tries to get back out of the gelcoat, the gelcoat prevents it from happening and causes a bubble from the pressure.

Why is this happening?

As a result of amendment #1113, hull blisters are becoming more prevalent. This amendment had the potential to eliminate 90% of available gel coatings, and the American Coating Association (ACA) even stated that coating performance would suffer (Article). This is just one example of known issues and concerns with the integrity of gelcoatings. Some gelcoatings may not need to be as water resistant, but your boat hull should be! (Article)

How can Gatorbak help?

One of the biggest concerns for our customers is to protect their investments. Bunk carpet can hold in moisture and muck for long periods of time, creating longer opportunities for gel coat blisters to form. Prolonged contact with wet bunk carpets only makes the problem worse. Gatorbak Synthetic Bunk Covers are designed to eliminate this risk! They are designed to shed water easily, and be quickly washed off and dried. Our synthetic bunk covers are made to be a direct replacement for boat bunk carpet so you don't have to worry about your boat when it's out of the water. Although we can't say that Gatorbak will totally eliminate the opportunity for blisters to form, we do believe our product can help prevent it.
