Earlier this summer I bought a Sylvan Sport Troller that needed new carpet. Once I dug into it and had all the carpet out, I found that the old treated plywood's glue was breaking down causing a lot of the wood to become brittle. I bought all new marine plywood and using all the old pieces as templates, cut everything out. Since I'm planning on keeping this boat for the long haul, I thought it would be a good idea to seal the wood before I installed and carpeted it.
Reading all the various threads I came across the "old timers" wood sealant formula and thought I would give it a try. I sealed everything with multiple coats and allowed it to cure a minimum of one week before top coating it with a few coats of Minwax spar varnish. After a little better than a week of curing time, I riveted the floor down and started to glue the carpet in. I'm using Roberts 6030 which is a solvent based adhesive, which I've had really good luck with in the past. This time, as soon as the glue had a chance to sit on the wood, it pulled the spar varnish right up and off of the wood.
Obviously the spar didn't adhere to the plywood. What did I do wrong? Did I misunderstand the process of sealing the wood? I hate to just throw all of my weeks of work and hundreds of dollars worth of plywood on the burn pile, but it's not looking good.
