How to Care for Your Surfboard: Ding Repair, Storage, and Maintenance Tips

Your Board Takes a Beating — Here's How to Keep It Alive

Surfboards aren't cheap. And even if yours was, it's the thing that connects you to every wave you ride. A crack you ignore for a week becomes waterlogged foam. A board baking in your car becomes a delaminated mess. Wax that hasn't been changed since last summer becomes a slippery liability.

The good news: surfboard maintenance is simple. A few habits and a $15 repair kit are the difference between a board that lasts one season and one that lasts five.

Ding Repair: The Single Most Important Skill

Every surfer gets dings. They happen when boards hit the sand, collide with other boards, get tossed against rocks, or simply take repeated impacts from waves. The critical thing is how quickly you fix them.

Why Dings Matter

A ding that breaks through the outer shell of your board exposes the foam core to water. Foam absorbs water like a sponge. Within a few sessions, a small crack can add pounds of water weight to your board, making it sluggish and eventually causing rot that no repair can fix.

Rule of thumb: If you can see white foam or the ding feels soft when you press it, water is getting in. Fix it before your next session.

What You Need

A basic ding repair kit should include:

• UV-cure resin (Solarez is the gold standard — get the type that matches your board: polyester for PU/fiberglass, epoxy for epoxy boards)
• Sandpaper in 120-grit and 220-grit
• Fiberglass cloth for deeper repairs
• A razor blade or utility knife for trimming
• Plastic wrap (regular kitchen cling film works)
• Acetone or rubbing alcohol for cleaning

This entire kit costs under $20 and fits in your glove box.

How to Fix a Small Ding (Under 1 Inch)

1. Dry the area completely. If the ding has been in the water, let it sit in the sun with the ding facing down for at least 24 hours. You can speed this up with a hairdryer on low heat, but patience is better.
2. Sand the area lightly with 120-grit sandpaper. This gives the resin something to grip. Sand about half an inch beyond the edges of the ding.
3. Clean the area with acetone or rubbing alcohol to remove any wax residue or dust.
4. Apply UV-cure resin. Squeeze a small amount over the ding — enough to fill it and form a slight dome above the surface.
5. Cover with plastic wrap. Smooth it down to create a flat surface and eliminate air bubbles.
6. Cure in direct sunlight for 5-10 minutes. The resin will harden when UV light hits it.
7. Sand flush with 220-grit sandpaper once cured. It should feel smooth and level with the surrounding surface.

That's it. Five minutes of active work and your board is watertight again.

Deeper Dings and Rail Cracks

For dings that go deeper into the foam or cracks along the rail:

• Cut away any loose or damaged material with a razor blade
• Let it dry thoroughly — deep dings hold more water
• Cut a piece of fiberglass cloth to cover the damaged area with about an inch of overlap
• Apply resin over and through the cloth, saturating it completely
• Cure and sand as above, but you may need a second layer for structural strength

If the damage is larger than your fist, or if the board is snapped or creased, take it to a professional shaper. A proper repair on structural damage is worth the $50-100 it costs.

Wax: More Important Than You Think

Wax isn't just "that sticky stuff on top." It's your grip. Wrong wax, old wax, or poorly applied wax directly affects how well you can pop up, pump, and maneuver.

Temperature Matters

Surf wax comes in temperature grades for a reason. Using the wrong one means either a rock-hard surface that provides zero grip, or a melted mess that slides off.

• Cold water (under 58°F / 14°C): Cold wax — hardest formula
• Cool water (58-68°F / 14-20°C): Cool wax
• Warm water (68-78°F / 20-26°C): Warm wax
• Tropical (above 78°F / 26°C): Tropical wax — softest formula

Always apply a basecoat first (a harder wax designed to create initial bumps), then apply your temperature-appropriate topcoat over it.

How to Apply Wax Properly

• Start with a clean, dry board (strip old wax first if rewaxing)
• Apply the basecoat using firm, diagonal strokes in a crosshatch pattern until small bumps form across the deck
• Apply the topcoat using lighter, circular motions over the basecoat bumps
• Wax the entire area where your feet and body contact the board — from the tail up through where your chest sits when paddling

When to Strip and Rewax

Strip your wax completely every 4-6 weeks, or when:

• The wax is yellowed, dirty, or flattened
• You're switching between water temperatures
• You can't feel distinct bumps when you run your hand across the deck

To strip: leave the board in the sun for a few minutes to soften the wax, then scrape it off with a wax comb. Clean any residue with a citrus-based wax remover or coconut oil.

Storage: Where Your Board Lives Matters

How you store your board between sessions has a massive impact on its lifespan.

The Cardinal Sins of Surfboard Storage

Never leave your board in a hot car. This is the #1 board killer. Heat causes the foam core to expand, pushing against the fiberglass shell. The result is delamination — bubbles and separations in the glass that weaken the board permanently. On a hot day, the inside of a car can reach 150°F+ (65°C+). It only takes 30 minutes to cause damage.

Never store your board in direct sunlight for extended periods. UV rays yellow and weaken the fiberglass over time. A board left on a porch or leaning against a sunny wall will age far faster than one kept in the shade.

Never store your board flat on a hard surface for long periods. The weight can create pressure dents over time, especially in hot conditions.

The Right Way to Store

• Indoors, out of direct sunlight. A garage, closet, or dedicated board rack is ideal.
• On its side or in a board rack. If using a wall rack, use padded hooks and store the board fin-side against the wall.
• In a board bag for travel or long-term storage. Reflective bags help with heat, and padded bags protect against impact.
• Off the ground. Leaning boards against walls leads to them getting knocked over. Wall racks or ceiling racks are better.
• In a temperate environment. Avoid uninsulated sheds or attics that experience extreme heat.

Transport: Getting to the Beach Without Damage

Most board damage happens outside the water — in parking lots, on roof racks, and during loading.

• Use proper roof rack pads or a soft rack system. Bare metal crossbars will dent your board.
• Strap your board deck-down (wax side down) on roof racks. This protects the bottom from UV and prevents the fins from catching wind.
• Don't overtighten straps. Enough to be secure, not enough to create pressure dents.
• Use a board sock or bag when transporting to protect against scratches and sun.
• Never stack boards without padding between them. Fins, leash plugs, and rails can damage adjacent boards.

Seasonal Maintenance Checklist

Every few months, give your board a full once-over:

• [ ] Inspect for dings — check the nose, tail, rails, and deck for any cracks or soft spots
• [ ] Check the fin boxes — make sure fins are tight and the boxes aren't cracked
• [ ] Inspect the leash plug — look for cracks around the plug and replace the leash string if frayed
• [ ] Strip and rewax — fresh wax makes a noticeable difference
• [ ] Check for delamination — tap the board and listen for hollow spots that sound different from the rest
• [ ] Clean the board — wipe down with fresh water to remove salt buildup

When to Replace vs. Repair

Not every board is worth saving. Here's the general guide:

• Small dings and cracks: Always repair. Cheap and easy.
• Waterlogged foam in one area: Repair if the area is small and you dry it completely. The board may be slightly heavier in that spot.
• Widespread delamination: Usually not worth repairing. The structural integrity is compromised.
• Snapped or creased board: A professional can sometimes repair a clean snap, but the board will never be as strong. Often better to replace.
• Yellowed, heavy, and waterlogged throughout: Time for a new board. It's done its job.

The Bottom Line

Surfboard care isn't glamorous, but it's one of the easiest ways to save money and surf better. A quick ding check after every session, proper storage, and regular wax maintenance are all it takes.

Fix dings immediately. Keep your board out of hot cars and direct sun. Wax with the right temperature formula. Store it properly.

Your board takes care of you in the water. Return the favor on land.
