For your wooden boat bu.
Epoxy to seal plywood boat floor.
Marine plywood is thicker than typical plywood so you ll need to apply more coats to maximize its lifespan.
Between the carpet and the floatation foam new floor was already deteriorating.
Just removed the carpeting and found several areas that were rotten on the floor.
But they didn t seal it.
I ve built a couple boats.
Plus the epoxy itself is quite strong and can be used on plywood that is both indoors and outdoors.
This was located underneath a faux teak floor meaning that it is most likely the original plywood used to build the floor of the boat.
It is almost always necessary to coat the marine plywood in additional sealer to block all moisture from the pores of the wood.

You ll find a lot of debate over epoxy encapsulation may people feel it just leads to checking on plywood particularly douglas fir which is great boat building wood btw and at the most epoxy alone just penetrates a millimeter or two into the wood.
This plywood is formulated to resist water and moisture on its own.
However usually the materials in the wood are not enough to block all moisture from the wood.
A scratch penetrates that pretty easily.
The advantage of an epoxy sealing product is that it protects the wood while allowing it to retain its natural color.
A good rule of thumb for sealing marine plywood is to apply as many layers of sealer as there are layers in the plywood.
This is a popular type of sealant that can be easily used on most plywood.
If you have purchased plywood with six layers for example apply six layers of epoxy to seal it.
Main floor was replaced 3 years ago with 3 4 marine ply.
Anyone have any ideas as to what i can use to deal the underside of the plywood.
With normal plywood you would use two coats of sealer maybe even three.
Allow the epoxy to dry completely before flipping it over and applying it to the bottom edge and back of the wood.
