I am trying to finish my project boat, a 1977 San Juan 26 and I ran into a problem involving adhesives. I used epoxy to glue .5 inch plywood furring strips to the coach roof (cabin ceiling) to which .25 inch thick pine strips would be fastened with screws for a nice wood ceiling. When I was about half way complete screwing the finished strips in place, some of the plywood furring strips detached. I could hear the epoxy separating from the roof. Today I removed the strips and the insulation and was able to pull all of the furring strips off with moderate force. Disappointed, but better now than on the relaunch voyage.
The problem appears to be that the epoxy did not adhere well to the roof surface. I might have skimped a little on the sanding prep, but the entire length of the epoxied strip popped off to an extent that made me think another adhesive would be a better choice. I am experienced with epoxy and it was not a bad batch. I speculated that the roof utilized polyester resin and not epoxy.
Is there a better adhesive to keep furring strips glued to the ceiling for the next twenty years? A fast curing adhesive would also help - gluing stuff to the ceiling is difficult as gravity never takes a day off. Liquid Nails, 5200, hot melt glue, epoxy, gorilla glue, cyanoacrylate, any others?.
Thanks for any suggestions. I have benefitted from reading this board over the past two years as I worked on my project. I will post some pics when she is done.
