Tyvek, vapor barriers and sealants for floor. What works best?

[KZGoodchild]

Hi, not sure of anyone has mentioned this stuff before, I use it on our sailboat, it's a two part epoxy paint called "Interprotect". By West systems. costs a bit, but I 've used it where water gets into in the cockpit, and I need structural strength in something (ie plywood holding the rudder on place- very important) and the stuff is like a rock years after application. I plan to do the outer edge of floor once at that stage (next week !!!))) Good luck with your project . Sorry In a rush so didn't read Streaming's post ! lot of sailors owning AS's >??? LOL
