To waterproof balsa wood, you can use a few different methods. One effective approach is to apply a sealant, such as polyurethane or epoxy resin, which creates a protective barrier against moisture. Another option is to use a marine varnish, which is specifically designed for wood exposed to water. Ensure that the surface is clean and sanded before applying the waterproofing agent for optimal adhesion.
