Water leak through vinyl and plywood from open deck, some area of plywood is rotten and become soft when walk on the surface of vinyl. The deck is 12' x 24', total of around 288 square feet.
I would like to replace the deck by using MDO plywood (Crezon Plywood) and then paint on the surface.
Do you think this will be the most economic way?
What type of sealant should I use for the joints between each piece of 4' x 8' plywoods. I think I need 9 pieces.
Our ambient temperature is from 30 degree to minus 10 degree Celsius.
Thank you for your advise.
