How to Repair a Surfboard Ding

Quality surfboards are expensive, so making sure they remain in good condition ensures that surfers protect their investments. Knowing how to repair surfboards at home saves surfers a lot of time and money as well. Rather than waiting several weeks for a surfboard repair shop to patch up the board, surfers can fix it and be back in the water in just a few days. Additionally, surfers can brighten up and bring old boards back to life by learning this process. With just a few supplies and a little bit of time, surfers can make their boards as good as new.

Gather Supplies

The first step for repairing a surfboard ding is for surfboard owners to gather all of the materials. Having everything combined and ready to use before beginning shortens the repair process. The average ding takes about 10 to 15 minutes to repair once surfers gather all of the necessary supplies.

Repair the Surfboard Ding

Repairing the surfboard ding is a simple process, but it requires several steps. Surfers cannot simply fill the ding and be on their way. Instead, users must prep the area before filling it and glassing it. The process is messy at first, but with a bit of practice, users can complete the steps and make the repair in just a few minutes.


Surfers prep the surfboard ding by first scraping away the wax and sand from the ding and cutting away the damaged fibreglass. They must use the sandpaper to clean up the rough edges of the area and brush away the excess dust. Surfers use masking tape to section off an area about an inch around all sides of the ding. This prevents the resin and other chemicals from reaching other parts of the board. If the foam inside the ding is still wet, users should dry the area completely using a hair dryer.


To fill the ding, users must mix the Q-cell into a thick paste. Once it is the desired consistency, they should also add about 10 drops of UV catalyst and stir well. The more catalyst added, the faster the resin cures; however, too much catalyst makes it brittle. Surfers pour this mixture into the ding, using a stirring stick to ensure it fills all cracks and crevices. The mixture should overflow from the ding just a bit. Once the mixture hardens, users sand it flush with the rest of the board.


To glass the repair, users cut a couple of small patches out of the sheet of fibreglass. They can then combine the sanding resin with about 10 drops of catalyst. They place one sheet of fibreglass over the ding and paint the sanding resin over it. Once the fibreglass absorbs the resin, users place the second sheet of fibreglass over it and repeat the process.

Sanding and Finishing the Repair

Once the resin cures, users should sand the area flat and smooth then apply another coat of resin. Finally, they use wet sandpaper to make the area completely smooth. As water mixes with the white dust from the sandpaper, it creates a glossy and smooth surface. For best results, surfers should let the repair sit for one or two days to ensure that it lasts longer and maintains its integrity.
