Fix a hole in a fibreglass boat with this easy ‘how to’ guide.
Did your fiberglass boat develop a hole? Never fear, all is not lost: with a few simple steps, your boat will be as good as new. Just follow these steps. You will be able to patch a hole in a fiberglass boat in no time.
7 Take your time. Patience is a virtue, especially when working with gel-coat. Carefully follow the manufacturer's instructions when mixing gel-coat. Work in a well-ventilated area to protect yourself from the fumes of the acetate and the gel-coat. Wear a dust mask and protective glasses when sanding fiberglass as the resulting dust is harmful both to your lungs and eyes.
Thoroughly clean the area with acetone, making certain it is free if dust, dirt, or anything else that could prevent the patch from being effective.
After the gel-coat has hardened, remove the wax paper, and lightly sand it until it is smooth. Curing time for the gel-coat will depend upon the thickness of the application. Read the manufacturer's instructions for this information.
