Many boating enthusiasts own boats made of fiberglass. This material is durable, affordable and lightweight, but can become damaged due to collisions or regular wear and tear over time. No one feels safe boating once a crack appears in their boat. Fortunately, repairing a crack in a fiberglass boat is relatively simple, though it does require a certain bit of skill and finesse. With patience, any boat owner can repair their boat and restore its like-new shine.
Protect your skin and eyes by wearing rubber gloves and safety goggles. This type of protection should always be worn when working with chemicals.
Use your resin applicator to fill any cracks or voids with epoxy resin. This material dries very quickly, so it's important to work fast once the epoxy is exposed to air.
Paint a thin coat of resin over top of the filled crack and immediately place a layer of fiberglass cloth over top. The coat of resin will hold the cloth in place.
Allow 4 to 6 hours for the patched area to dry. Wet the sandpaper and carefully sand down the repaired area until it is level with the rest of the surface. Sand slowly, as you don't want to over sand the patch.
Use a paint brush to apply a coat of marine gel enamel to the repaired area. The gel enamel will give the boat a shiny, like-new finish. Using an enamel made for marine applications will ensure it will be able to hold up against exposure to the sea and the environment.
