replacing wood on rear seat

[maddog2]

I have started to rebuild my rear seat in my 1992 Celebrity 190 BR.
I couldn't afford the marine plywood, so I purchased the treated plywood for this project.
I know that it my not last as long as the marine plywood, but the original wood was only 1/2" and I am using 3/4".

Can I glass the treated wood or should I just coat it in Polyurithane?

Hello maddog2..

There are reasons why I personally do not use treated wood in my repairs..

some this..some that..It just does not work with what I do m8..

Check out some sites like this and get as much info as you can with what you used.

Treated plywood will certainly stop the termites

Sometimes treated plywood does not take to resin due to it's moisture content..... it will last plenty long if you want to just seal it up..... but I would use spar varnish. Are you going to cover it with vinyl too?

You have options for prep but ultimately you are going to put holes through the "sealer" and give water a way in, but not necessarily out.

My guess or suggestion would be: If you use treated, seal it with a breathable sealant and expect to replace it in a couple of years depending on the environment and exposure.

Congrats on you choice of pressure treated lumber. Just leave it as is. It won't rot if it gets wet, and it will dry if you don't seal it. If you use standard marine plywood, it WILL rot if it gets wet because its not pressure treated.

BWT, APA (engineered plywood association) suggests the use of treated plywood in boats.
