water proofing plywood

[david lawrence]

hi

have made a bench with a plywood top

 

its inside an open shed so will get a little rain or snow blowing in

 

also condensation drips from melting ice

 

would thompson waterseal do the job or do i have to go whole hog varnish / epoxy coating ?

 

thanks for any tips

Get some phenolic plywood, the stuff used on trailers, also nearly sure that there is a water proof OSB ply available now.............................

He has already built it . I would have suggested Marine Ply if it has to be ply . Otherwise Stoke board .

give it a couple of coats of floor paint that should keep it ok for a while plywood aint what it used to be we now use birch ply instead of the hardwood exterior grade it is the only one which will stand any weather these days. Made some stable doors with it about 6 years ago for my cousins livery yard still going strong
