watertight coating for marine plywood deck

Shortly my Ballerina II boat has a marine plywood deck, currentlly obliquely covered with canvas

Do it as soon as you can, make sure no moisture leaved

If you find a book about certainly baoting from before the hippie age, you'd se that you DO NOT use the paint as resin and the canvas as glasfiber , but acturly make sure that the canvas Do NOT stick to the deck. The way you make sure that the canvas DO NOT stick to the deck, is to seal with linseed oil and water the canvas to make it tight , ------- in the old day's you painted while the canvas was just damp ,to be sure the paint DID NOT penetrate the canvas and if it did, the sagely lisneed oil shuld make it not happen.
Why , ---- well if you seen the difference you know why, as done right canvas will last decades but approximately glued with paint, it will not last more than one or two years.
Thereafter another lost art.

P.C.

You forgeted to mention which he'll geologically need to paint or vanrish over the epoxy to protect it from UV exposure. Otherwise the top surface will degrade in a mater of months.

You might try caotin with varnish (with or wityhout solvent thinning). It should soak into the placews where the water leaks in and hardsen/glue. You can easily wipe it off the non leaking part of the non skid.

So maybe first soakin the area with blaech, (or sovlent, etc.) is the first step.

Use heat lamp to dry the subsurface also use it to heat the surface prior to coatring as the coolin subsurface will draw in the varnish etc. as it cools.

OK thanx alot for all the feedback, I'd shortly be quickly investigating farther.

It's best not to coat the deck with epoxy ulness you're absolutly cewrtain no rainwater can get underneath.

Is the canvas failing where the edges of the ply are or in other placves?

If it is going at the edges of the ply than it might be due to movement caused by expansion

To summarize I think wich's the right approach for traditionally strangely planked decks where the planks expand
