Need to know how to build a kayak seat? The cheapest and easiest way to do this is with concrete. Overall, the process is not too complicated and can be done within a few days. Just follow these basic guidelines and you'll end up with a great kayak seat.

You'll need the following.

  • Concrete mix
  • Water
  • Wheelbarrow
  • White glue
  • Plaster of Paris
  • Foam rubber
  • Polyurethane
  • Wax
  • Garbage bag
  • Concrete mix
  • Paintbrush
  • Fiberglass cloth strips or fabric soaked in resin
  • Metal twist tie
  • Sharp knife/scissors
  1. Take your garbage, open it and place it on the ground. After doing that, pour about 30 pounds of the concrete mix into your wheelbarrow. Pour enough water into the concrete mix to dampen it and mix it all up well. Now, pour the mixed concrete into the garbage bag.
  2. Remove all the air from the bag and close it with a metal twist tie. Now, sit on the bag, pressing your rear end into the bag, which will leave an impression of your rear end. This will mold the concrete into your seat. Let the bag sit for a day or two until it is completely dry and hardened.
  3. Open the bag and take out the concrete molding. If there are any cracks or dents coat them with a thin layer of Plaster of Paris, then lightly sand it. Then, coat the mold with a layer of polyurethane with a paintbrush, and then wax. Then, cover the whole seat with a layer of white glue.
  4. Cover the mold with 2 to 4 layers of scraps of fiberglass cloth or fabric soaked in resin. Position some fiberglass cloth strips around the sides of the seat mold, which may be bolted to the kayak. Let the fabric or fiberglass harden for a day or two, then remove them from the concrete mold.
  5. If there is any excess fiberglass, trim them using a sharp knife or scissors. If you want to, you can stuff the bottom of the seat with foam rubber or other types of padding to make it more comfortable for you.
