How to fix the tail of your surfboards

The tail on your surfboard is one of the most unstable areas, and it receives bumps and blows quite often, both from the ground as well as from the scraping of the leash. This is why we are going to explain to you how you can repair the tail yourself and how to do it well.

1. Preparing the area to be repaired.

You must eliminate all of the pieces of fiberglass that have separated from the foam. Using a knife or a cutter, get rid of all the pieces of fiber and foam that are scratched or detached, leaving the board clean, and of course, dry.

2. Rebuilding the tail

You are now going to rebuild the tail, in order to give it its original shape. For that, make a mold, a type of framework around the tail, where you will introduce a mixture of resin and glass microspheres.

You can use a radiograph to make the framework, keeping the pieces of radiograph under the board and around the tail with adhesive tape. Then, prepare a mixture of resin (polyester or epoxy, depending on the make up of your board) with glass microspheres and a PMEK catalyst. The glass microspheres make the resin grow in volume, but not in weight. They are ideal for repairing any kind of deep blows to your board. Fill in the framework with this mixture, allow it to harden and then remove the mold.

3. Reinforce the tail with fiberglass.

If the glass microspheres and the resin and perfect for filling and and rebuilding a deep part of your surfboard, they are not sufficiently strong, and in an area as delicate and in demand as the tail, it is necessary to place a piece of fiberglass which is going to provide the necessary robustness.

Cut off a piece of fiberglass weighing between 4 and 60 ounces so that it covers the entire area of the tail to be repaired. The piece must cover both the deck and the bottom of the board. Impregnate it with a mixture of resin and catalyst, allow it to harden, and then apply a mixture of polyester resin with parafin estirene PMEC catalyst, if your board is made of polyester, or of epoxy resin and its catalyst, if your board is made of epoxy. This last coat, called a gel coat or hot coat by the shapers, allows the surface to even out and makes the resin able to be sanded.

4. Final sanding

Sand the area beginning with thick sand paper of 80 grain, until you make the area perfectly smooth, without any lumps or holes. Once this is achieved, and in order to make the repaired area look the same as the rest of the board, sand with progressively finer sandpaper. After the 80 grain sandpaper, you can subsequently sand with 120, 180, 240, 360 and 500 grain sandpaper until you get a smooth and matte.

Knowing how to repair the board yourself is not only an economic savings, but above all it gives you a sense of tranquility. The tranquility that comes from knowing that the time to repair the board depends exclusively on you and that you wont miss a dip due to not having your board repaired.
