Can you strengthen rotted wood?

Once rotted wood has actually crumbled, your options for strengthening it are limited to scraping out the rotted wood and filling the cavity. You’ll find several brands of two-part epoxy or polyester wood fillers at the store that are suitable for this purpose, and all of them set harder than the wood you’re repairing.

How do you keep wood rot from getting worse?

Monitor the wood because it’s still at an increased risk of future rot.

Because it doesn’t harden like wood filler, wood putty won’t shrink or crack, but you can’t sand it.
