How to Care for Your Surfboard and Fins: Maintenance Guide

Proper maintenance extends the life of your surfboard and fins by years. A few simple habits prevent costly repairs and keep your equipment performing at its best.

After Every Session

Rinse with fresh water:

• Remove salt, sand, and debris from board, fins, and leash
• Pay attention to fin boxes and screw areas
• Let everything dry in the shade, not direct sunlight

Board Care

Preventing pressure dents:

• Store board face-down or on a soft rack
• Use a board bag for transport and storage
• Avoid leaving in hot cars (heat softens foam)
• Repair dings immediately — water in foam causes delamination

Repair basics:

• Small dings: Solarez or epoxy putty
• Cracks: Professional repair recommended
• Never surf with a ding — water absorption destroys foam cores

Fin Care

Keeping fins in top condition:

• Check fin screws after every session
• Remove fins for travel to prevent box damage
• Clean fin tabs with a soft cloth
• Inspect for cracks, especially at the base

When to replace fins:

• Visible cracks in the base or tip
• Permanent deformation or "packing out"
• Reduced performance or unusual flex
• Damaged tab or mounting system

Travel Tips

For air travel:

• Use a padded board bag with fins removed
• Wrap fins individually in bubble wrap or cloth
• Place fins in the center of the bag, surrounded by soft items
• Label your bag with contact information

For car transport:

• Secure boards with soft ties, not ratchet straps directly on the rail
• Don't overtighten — compression causes damage
• Keep boards out of direct sun when parked
