Repairing rotted core on a boat can be a more complicated repair process than fixing rot on the surface. Here are the steps to repair rotted core on a boat:
Identify the extent of the damage: Before starting the repair process, it is important to identify the extent of the damage. You can do this by tapping the affected area with a mallet or screwdriver to determine the soundness of the surrounding material.
Remove the damaged material: Once you have identified the extent of the damage, remove the damaged material by cutting out the affected area with a saw or grinder. Make sure to cut beyond the damage to ensure that you remove all of the affected material.
Dry out the area: After removing the damaged material, dry out the area completely to prevent further rot. Use a heat gun or hair dryer to dry the area thoroughly.
Prepare the replacement core: Cut a piece of new core material to match the dimensions of the removed area. The core material can be made of foam, balsa wood, or another suitable material.
Install the new core material: Apply a marine-grade adhesive to the area where the new core material will be installed. Then, carefully fit the new core material into the area and secure it with screws or clamps.
Replace the outer layer: Once the new core material is installed, replace the outer layer of the boat, whether it is fiberglass or another material. Use a marine-grade adhesive to bond the outer layer to the new core material.
Finish the repair: Once the outer layer is replaced, sand the area to ensure it is smooth and flush with the surrounding material. Finish the area with a marine-grade sealant or paint to protect it from future damage.
It is important to note that repairing rotted core on a boat can be a complex and time-consuming process. It is recommended to seek the help of a professional boat repair technician if you are unsure about the process or the extent of the damage.
