How to Repair Rotten Wood

Auto body filler works great for repairing rotten spots in wood since it hardens in a matter of minutes and can be used to fill large areas.
Start by using a chisel to remove the rotten wood. If the hole is large, drive a few nails or screws below the finished surface to give the filler something to grab onto.
Next, mix up a batch of filler, and apply it to the hole following the safety instructions on the can. It sets quickly, so don’t mix up more than you can use in a minute or two.
Once the filler has set for a few minutes—but before it has time to get really hard—use a sharp chisel or hand plane to remove any excess, then sand it smooth and finish.
