CAUTION: Using antifreeze is dangerous and can be harmful or fatal to humans or animals if ingested. Use extreme caution.
He let the wood dry for a week before moving on to the next step – application of the epoxy resin.
Thinning Epoxy Resin to Seal Wood From Moisture
Epoxy resin is mixed with a hardener to produce a strong, waterproof bond.
The bonding characteristics of epoxy solidify the rotted wood and seal the area against water.
To make the epoxy cover a larger area, you’ll need to thin it 50% using one of several thinning agents.
You can buy specialty resins designed specifically for fixing rotted wood flooring, but you probably don’t need it for a small area of a camper. Those resins are usually needed in boat repairs where the wood is continually exposed to extended moisture.
If you’re not using Git-Rot, then you’ll need some standard epoxy resin, hardener, and a thinning agent.
This step might require some new materials that you may not have used before.
Depending on the epoxy and hardener you buy, you’ll only have a few minutes to an hour to work with it. What you’ll need to do is mix the epoxy resin and hardener, and stir in the thinning agent.
The three things you can use to thin the epoxy are:
