Painting the New Catamaran

The next stage of the Kitchen and Sanitary Float is getting the steel tanks painted and ready for the water. Every boat is painted with either an epoxy resin or bitchumen to protect the boat from rust and damage in the water. This is normally repeated after 2 - 4 years, depending on the water type the boat sits in (painting is required more often for boats in salt water). However, boat paint is notoriously expensive and we wanted to explore ways of making a very similar paint that encompasses the Flydende By spirit and reuses materials that we are unable to currently recycle.

Our main criteria for the paint we need:

  • Rust protective,
  • Durable in salt water,
  • Long lasting and scratch proof,
  • Safe for marine life,
  • Cost effective and uses recycled materials.

Through several tests we have managed to develop a paint solution from dissolving polystyrene with gasoline. So far from our tests we have concluded that it works just like normal boat paint. We have yet to see the long term effects of the paint, but we have seen the promising effects of the paint on both rusty and clean steel that has been left in the harbour water over a period of weeks.                                                                                          

Step 1: Breaking the blocks of polystyrene into small beads.                                       Step 2: Mixing together until it completely disolves into a paint


This is what our first test area looks like, a very thin and see-through like consistancy. Just the rest of the boat to go!

Once this boat is fully painted with several layers, we can move onto creating the deck area above and then look at getting the boat out of the warehouse and into the water.
