Surfboards take a lot of abuse, especially if you surf near rocky shores or bluffs. Even densely packed seaweed can cause damage to a board if it strikes with enough force. Chips, small dings and cracks are normal occurrences for the avid surfer, and most minor damage is repaired simply. Boards are made from either polyurethane foam or expanded polystyrene (EPS) foam. Repairing an EPS board requires an epoxy resin for best results.
Dry off the entire board with a towel, ensuring that all sand and other debris is cleaned from the damaged side. If the board is cracked, dry the depth of the crack with a hair dryer turned to medium heat.
Open your container of epoxy resin and mix it according to the directions on the container. If desired, add several drops of pigment to the epoxy to help it blend with the color of your board. The more drops you add, the deeper the color of the dried epoxy will be.
Pack epoxy into the chip, ding or crack using a plastic spoon.
Spread the epoxy flat over the damaged area using a putty knife. Repeat the spreading motion to ensure that the epoxy is well packed. Once finished, the epoxy should be flush with the rest of the board.
Scrape off excess with the knife's blade and redeposit it in the container.
Allow the epoxy to dry and cure for the time suggested on the container, usually 24 hours.
Attach a fine grit sandpaper pad to your power sander and use it to smooth the epoxied area of the surfboard.
Blow away surface dust to check your progress. Continue sanding until the epoxied area is completely smooth to the touch.
Wipe the board clean with a damp cloth.
Tips & Warnings
- If you are repairing a small or lightweight surfboard, brace it to your work table with C-clamp tool or weight it with a heavy object prior to sanding.
- Preserve the epoxy for future repair jobs by replacing the top of the container immediately after use. Store it in a cool, dry area.
- Bring your board to a professional repair service if a large portion of it has broken off, or if a long hairline crack has occurred.
- Wear safety goggles while sanding the epoxied area.
- Do not allow children or pets near your work area.
