How to Waterproof a Kayak

Kayaking is a fun and exciting sport that requires physical fitness. Many kayak materials, such as plastic or resin, are waterproof as a result of the material used. Unfortunately, some kayak materials like wood require adding appropriate waterproofing, especially if the kayak is made at home. Store-bought wooden kayaks will often have waterproof finishes. However, waterproofing is still required after a certain time period, which differs based on the waterproofing finish.

      Cover the kayak in epoxy sheathing. Epoxy sheathing not only adds waterproofing to the kayak, but it also strengthens the wood and helps prevent damage. The sheathing applies a type of fabric to the kayak. A twill or plain weave fabric is best because they are general purpose. Cut the fabric to the size of the kayak, using tape to hold it in place if necessary to ensure enough fabric is used and then removing the fabric from the kayak. Apply epoxy by placing the fabric on a flat surface, pouring small amounts onto the fabric and then using a squeegee to spread the epoxy evenly over the fabric. Avoid leaving white spots and use more epoxy if necessary to cover it. Place the fabric on the kayak and then use a squeegee to get out the bubbles.

      Add a waterproof varnish to the kayak. The varnish fixes and repairs any cracks and maintains the strength of the wooden material. Usually a varnish is added with a paint brush or an applicator brush. Allow the varnish 24 to 48 hours to dry completely.

      Apply a waterproof finish to the kayak. Completely cover the entire kayak, from the front to the back. Waterproofing a kayak requires covering every inch. The bottom of the kayak is not the only area of the ship that gets wet. Even the inside will get wet if the kayak capsizes and goes upside down.

      Allow the finish to dry. Apply a second coat of finish to the kayak. At least two coats are necessary for waterproofing a material that is constantly in the water. Those that kayak often might want to add more than two coats.
