Advice refinishing teak and holly sole
Definitely use the Varnish over Epoxy method or just epoxy alone since this won''t need UV protection.
Don''t thin the epoxy - not necessary.
Don''t sand finer than 80 grit to ensure good adhesion.
Coat the bottom and edges as well as the upper surface to completely seal the wood from moisture.
There are epoxies meant for clear coating that produce a lovely surface that is durable.
For exterior wood, put varnish coats over the epoxy to protect from UV. The varnish protects the epoxy from the sun, the epoxy seals against water. Varnish is a poor sealer against water.
This technique has been the best for me so far. Exterior wood can be given a light sanding and a new coat of varnish when needed. As long as you seal it well with epoxy, the water will never get under the coating and you''ll never need to sand to bare wood again.
