Delamination is a serious issue that can affect the structural integrity of a fiberglass boat. It is a phenomenon where the layers of fiberglass separate from each other, resulting in bubbles or blisters on the surface of the boat. You should repair the delamination as soon as possible to prevent further damage. Here’s.
Step 1: Identify the affected area
First, you have to identify where the delamination has occurred. You can do this by tapping the surface of the boat with a hard object such as a hammer. The areas that produce a hollow sound are likely to be delaminated. Alternatively, you can look for bubbles or blisters on the surface of the boat.
Step 2: Remove the damaged area
Once you have identified the affected area, you need to remove the damaged fiberglass layers. You can use a grinder or a sander to sand the area down to the unaffected layers. Be sure to wear a respirator mask, gloves, and safety glasses to protect yourself from the dust and fiberglass.
Step 3: Clean the area
After removing the damaged layers, clean the area thoroughly with acetone to remove any debris, wax, or grease.
Step 4: Cut and fit new fiberglass layers
Cut new fiberglass layers to fit the size of the affected area. You can use a fiberglass mat or a woven cloth for this. Make sure to cut the layers slightly larger than the damaged area to ensure they cover the entire affected area.
Step 5: Apply resin
Apply a layer of resin on the damaged area and then apply the fiberglass layer on top of the resin. Use a brush or a roller to smooth out the layer and remove any air bubbles. Repeat the process until the affected area is covered with enough layers of fiberglass to match the thickness of the original layers.
Step 6: Allow to cure
Allow the resin and fiberglass layers to cure according to the manufacturer’s instructions. Typically, this takes several hours or a full day.
Step 7: Sand and paint
Once the fiberglass layers have cured, sand the surface to smooth out any rough edges. Then, apply a coat of gelcoat over the repaired area to match the color of the rest of the boat.
Repairing delamination on a fiberglass boat requires some work and proper safety gear, but it is a job that can be done by any do-it-yourself boater. With the right tools and materials, you can fix delamination and restore the integrity of your boat’s surface.
