Surfboard Shaping & Repair FAQs

Can you repair a snapped surfboard?

While it’s one of the more difficult repairs, you can indeed fix a buckled or snapped board. There’s a chance it’ll feel different once it’s fixed, but it can live to surf again.

How do you repair a surfboard?

The specific steps will vary depending on the type of repair, but most involve cleaning and sanding the damaged area, filling in any divots left behind, and adding a new patch of fiberglass.

How do you shape a surfboard?

Shaping a surfboard comes down to planning, patience, and focus. Design what you want to make, shape the blank with a planer, rasps, and sanding, and the fiberglass and sand it.

When should you repair your surfboard?

You should repair your surfboard if you notice or suspect that it’s taking on water.

Where to buy surfboard blanks?

You can buy surfboard blanks direct from the manufacturer, surfboard supply shops, and some of your local surf shops. If you’re only buying a small quantity of blanks, you’ll probably want to pick it up as shipping can get expensive.

Why are shaping rooms blue?

Many surfboard shaping rooms are blue because it helps you spot shadows and differences in the surface of the blank more easily. You can find shaping rooms in a variety of colors. Pretty much anything other than white will work.

Can you use an angle grinder as a sander/polisher?

You can find sanding/polishing pad attachments for many types of angle grinders. The main thing you’ll need to think about is the speed. Angle grinders are typically spinning much faster than a sander – if you want to convert it, you’ll need to make sure it will go slow enough.

How do you stop fiberglass itch?

Fiberglass can be a pain to work with – it’s going to itch if you don’t take the right precautions, and sometimes even if you do. Some remedies for fiberglass itch include a cold water rinse, sticking tape over your skin, and rubbing yourself down with a wet microfiber cloth.
