How To Repair A Paddleboard

Understanding how to repair your paddleboard, whether a solid or inflatable SUP, is essential for ensuring its longevity and your safety on the water.

This step-by-step guide will teach you how to repair a Paddle Board properly.

An Important Note Before You Start Repairs

Before undertaking any repairs on your paddle board, it’s highly recommended to consult the board manufacturer for guidance. 

Each paddle board is uniquely crafted with specific materials and construction techniques, and the manufacturer is best equipped to advise on the most suitable repair methods and materials for their product. 

Manufacturers can provide invaluable insights into the nuances of their boards, which can be particularly important when dealing with complex issues like delamination or structural repairs. 

Also, consulting with the manufacturer will ensure you avoid voiding any warranties or causing further damage to your board. 

Identifying the Damage

Before diving into repairs, the first step is to thoroughly inspect your paddleboard for any signs of damage. This process varies slightly depending on whether you have an inflatable or a solid board, as the types of damage they are prone to differ.

For Solid Paddle Boards

• Surface Scratches and Dings: These are common and usually superficial. Look for any breaches in the outer layer that might allow water to penetrate the core.
• Cracks and Deep Gouges: are more serious, so pay close attention to areas around the nose, tail, and rails.
• Delamination: This occurs when the board’s layers start to separate. Look for any bubbles or areas where the surface feels softer.

For Inflatable Paddle Boards

• Punctures or Cuts: Small punctures can be hard to spot. Inflate the board fully, listen for escaping air, or use soapy water to identify leaks.
• Valve Issues: Check the valve for any leaks or damage. A loose valve can cause the board to deflate unexpectedly.
• Seam Separation: Inspect the seams where different board parts are joined together. Any separation here will cause issues.

Tips for a Thorough Inspection

1. Clean First: Start with a clean board. Dirt and sand will hide small hard to spot damage.
2. Good Lighting: Ensure lighting is good so you don’t miss any small cracks or punctures.
3. Touch and Feel: Run your hands over the board. Sometimes, you can feel imperfections that aren’t immediately visible.
4. Check Regularly: Regular check-ups are a good idea, even if you don’t suspect any damage. Early detection is key to preventing minor damage from becoming a major problem.

2. Sand the Damaged Area: Lightly sand the area around the scratch or ding to help the repair material adhere better.
3. Mix the Resin: Mix epoxy resin according to the manufacturer’s instructions.
4. Apply the Resin: Use a small brush or spatula to apply the resin to the damaged area. Fill it and level it with the surrounding area.
5. Allow to Cure: Let the resin to cure as per the instructions. 
6. Sand and Finish: Once cured, smooth the area with fine-grit sandpaper and clean off dust.
7. Optional Finish: You can apply paint or varnish to match the board’s original finish.

Repairing Major Damage On Solid Paddle Boards

For more significant damage, like large cracks or holes, the repair process is a bit more involved:

1. Dry the Board: Ensure the board is completely dry. If water has penetrated the core, it may need to sit in a dry, warm place for a few days.
2. Remove Damaged Material: Use a Dremel tool or sandpaper to remove any frayed or damaged material around the crack or hole.
3. Prepare the Area: Clean it with acetone or alcohol and sand it to create a rough surface for better adhesion.
4. Cut Fiberglass Cloth: Cut the fibreglass cloth to cover the damaged area, extending an inch around it.
5. Mix and Apply Resin: Mix the resin and apply a thin layer to the prepared area. Place the fibreglass cloth over the resin and then apply another layer of resin over the cloth.
6. Smooth Out the Cloth: Use a brush or a plastic spreader to smooth the cloth and remove any air bubbles.
7. Cure and Sand: Allow the resin to cure completely. Then, sand the area smooth with progressively finer grits of sandpaper.
8. Apply Gel Coat (if applicable): If your board originally had a gel coat, apply a new layer to match the board’s finish.

Handling major repairs on your own can be challenging. If you’re not confident in your ability, consider seeking professional help. 

Remember, the goal of these repairs is not just cosmetic; it’s also to ensure your safety.

Patching Up Inflatable Paddle Boards

Inflatable paddle boards can puncture, but with the right approach, they can be repaired:

1. Locate the Leak: Inflate the board and listen for escaping air. Apply soapy water over the surface and look for bubbles that indicate a leak.
2. Deflate and Clean the Area: Once you’ve found the puncture, deflate the board and clean the area around the puncture thoroughly.
3. Prepare the Patch: Cut a patch from the repair kit, ensuring it’s large enough to cover the puncture with some overlap. Round the patch edges to prevent peeling.
4. Apply Adhesive: Apply the adhesive to the patch and the area around the puncture. Follow the instructions regarding drying time.
5. Place the Patch: Carefully place the patch over the puncture and press it down firmly. Using a roller or spoon removes air bubbles and ensures a good seal.
6. Let it Cure: Allow the patch to cure according to the adhesive instructions.
7. Check the Seal: Once cured, inflate the board slightly and check around the patch for any leaks. If it holds air, your repair is successful.

Fixing Delamination On Solid Paddle Boards

Delamination in solid boards can be a tricky issue, but it’s not insurmountable:

1. Identify the Delaminated Area: Look for bubbles or areas where the board’s layers have separated.
2. Heat: Using a heat gun, gently apply heat to the delaminated area. This makes the material more pliable and easier to reattach. Ensure overheating doesn’t cure, as this can cause more damage.
3. Apply Pressure: Once the area is warm, apply pressure to reattach the layers. You can use clamps or weights for this. Use a protective layer, like a cloth, to distribute the pressure evenly and prevent indentations.
4. Let it Cool: Allow the board to cool down and set it under pressure. This might take a few hours.
5. Seal the Edges: If there are any edges where the delamination was particularly bad, you may need to seal them with resin to prevent future separation.
6. Sand and Finish: Once the board is fully set and cool, sand the area smooth and apply any finish to match the rest of the board.

Repairing delamination requires patience and a gentle hand. If the damage is extensive, or if you’re unsure of the process, consult a professional.
