If the wood is rotten, it has lost strength. Really, the only thing you can do is to cut out the rotten wood and replace it. If it’s a wood cored fiberglass hull, that means you need to cut out and replace the fiberglass, where the wood needs to be cut out as well. Repairs are expensive.
Can you fiberglass over rotten wood?
Polyester resin is a fiberglass resin that is used for a lot of general fiberglass jobs. Fiberglass will bond to many different surfaces including wood, Styrofoam and even metal.The mat will form and bond to the wood, creating a protective layer over the wood.
Can you cover rotten wood?
Use a small to medium brush to spread the hardener onto the surface, filling in cracks and completely covering the wood which surrounds the area where the rot was found. This will solidify and strengthen it, in order to protect its structural integrity.
Can you fiberglass over a wooden hull?
One technique is to simply fiberglass over the wood hull of the boat, essentially sealing out the water and adding the structural strength of the fiberglass to the hull.
Does fiberglass bond to wood?
Fiberglass resins will not stick to woods that have been treated. They only stick to untreated, clean, dry wood. Redwood is not only usually treated, but it also contains a waxy substance prohibiting adhesion.
How do you fix rotted wood without replacing it?

Can you use fiberglass resin to waterproof wood?
Polyester resin is used for laminating fiberglass reinforcement, molds and, yes, waterproofing wood. It comes in two types, finishing and laminating. Finishing resin is basically laminating resin with added wax that allows it to fully harden.
How do you get fiberglass to stick to wood?
You can glue fiberglass to wood with an epoxy resin. Epoxy will glue almost any materials together and is the adhesive of choice when gluing fiberglass to wood. Epoxy has the advantage of spreading across the two surfaces and filling in gaps that are visible between the fiberglass and wood.
Can I lay fiberglass over plywood?
Plywood can be greatly reinforced with a few layers of fiberglass. Applying fiberglass over plywood can be a tricky process, whether you are covering a small piece or an entire deck.

Does wet rot become dry rot?
As the name suggests, growth of wet rot requires a higher moisture content in the timber than dry rot does. Wet rot will begin to grow when the moisture content of the timber or other permeable surface reaches around 50%, while dry rot can grow with as little as 20%.
What do you spray on rotted wood?
Boric acid (borate) is one of the most effective fungicides for use in treating wood rot. It can be applied to wood during construction to prevent future rot, or as a treatment to stop an active decay fungus from growing.
