We have a deck that is on top of a slightly sloped flat roof, and would like to seal the deck to minimize water seeping down to the aging roof.
The decking is 1 * 6 wood, with a nice weathered gray stain. Boards are laid side by side, and most seem tight enough to minimize leakage already. There are probably a few gaps as large as 1/4 inch. The deck is in two levels, and has essentially no slope. I can't really tell where water will go if we do a better job of reducing flow through the cracks; I tried running the hose on the surface for a while but couldn't get the water deep enough to really tell what would happen if there was a lot of water.
Is this conceptually sound? If so, what should I do, with what products?
Could I try a sealing primer like "Safe-T-Prime" to try to really leakproof the deck, or would I be better off just using a wood sealant? If I use Safe-T-Prime, will I be dissappointed in the appearance of the wood deck?
Thanks ...
