Fiberglass Boat Deck Repair

Fiberglass boat decks are prone to various issues, including:

• Cracks and Chips: Often caused by impacts or heavy foot traffic.
• Delamination: This occurs when the fiberglass separates from the underlying core material.
• Soft Spots: Usually a result of water infiltration, leading to rot and weakening the deck structure.

Materials and Tools for Deck Repair

For fiberglass boat deck repair, you will need:

• Fiberglass repair kit
• Sandpaper (various grits)
• Acetone
• Fiberglass cloth
• Epoxy resin and hardener
• Mixing containers and sticks
• Protective gloves and mask
• Paintbrush
• Marine plywood (if replacing core material)

Repairing Deck Cracks and Chips

1. Clean the Area: Use acetone to clean the damaged area, ensuring it is free of dirt and contaminants.
2. Sand the Edges: Sand the edges of the crack or chip to create a beveled edge.
3. Prepare the Fiberglass Cloth: Cut fiberglass cloth to fit over the damaged area.
4. Mix the Epoxy Resin: Mix the epoxy resin and hardener as per the kit instructions.
5. Apply the Cloth and Resin: Apply a layer of epoxy resin to the damaged area, place the fiberglass cloth over it, and saturate the cloth with more resin.
6. Smooth and Cure: Smooth out any bubbles and allow the repair to cure.
7. Sand and Finish: Sand the repaired area until smooth and apply a finishing coat or paint as needed.

Addressing Delamination and Soft Spots

1. Identify the Affected Area: Tap the deck with a small hammer to identify areas that sound hollow, indicating delamination or soft spots.
2. Remove the Damaged Core: Cut out the damaged fiberglass and remove the underlying core material.
3. Prepare the Replacement Core: Cut marine plywood to fit the removed area.
4. Apply Epoxy and Fiberglass: Apply epoxy resin to the replacement core and fit it into the deck. Layer fiberglass cloth over the repair, applying resin between layers.
5. Smooth and Cure: Smooth the surface and allow it to cure.
6. Sand and Finish: Sand the repaired area and apply a finishing coat or paint.
