Congrats on completing the job!
I'm picking up some new teak and holly plywood tomorrow to replace my 30 year old cabin sole. I read earlier that you epoxied the bottom and edges and varnished the top. If you don't mind my asking, which products did you use for:
Did you use anything like a sanding sealer on the top/exposed section of the teak and holly? Any pics?
You really shouldn't ask me. I'm a hack. Woodwork and carpentry is my weakest point. I do engines, electrical/electronics and plumbing.
To seal the underside and edges, I used TotalBoat penetrating epoxy from Jamestown Distributors (cold weather formula, since it's winter). I thinned it with acetone. You can also use denatured alcohol. This soaks it deep into the wood.
I did NOT epoxy or seal the walking face because I was unsure of product compatibility between the epoxy and whatever varnish I would finally choose. I felt that the varnish would protect the walking face enough if I maintain it.
After 2 weeks of talking with people, I receive advice from the standard "Epiphanes" to "buy a cheap floor varnish." I'd heard some bad things about water based varnish, so I ruled those out. I ended up settling on this floor varnish by Deft called "Defthane." It's an oil based, polyurethane floor varnish with UV stabilizers. That ticked all of my boxes. I chose to use a satin finish because...we're walking on it and because the satin finish is more forgiving to mistakes than a high gloss finish.
I sanded everything as per the instructions of whatever product I was using. By hand, with the grain.
The Defthane indicated that 4 coats would be enough. I applied 7 coats. That used up nearly 2 quarts of varnish, so I think it's on there pretty thick.
