If you are looking for some useful wood/metal related tips, don’t forget to check them up.

Identify the rot

The first thing to do is to identify the rot. If you can’t even find it, how do you know you have it? Take flashlight and flathead screwdriver with you. Look for hollow spaces/flexible spaces in the wood.

Make sure to pay special care near the wood joints and the point where the wood meets concrete. Those areas can easily be moisturized and rot.

Look at dark color wood around the house. That can lead to water-related rot.


You can do it yourself, but you will need some tools to help you. Don’t worry, the list isn’t too long, and you will find all of them in your nearest hardware store. If you can’t just order them online.

  • Paintbrush.
  • Putty knife.
  • Rasp.
  • Utility knife.
  • Wood chisel.
  • Sandpaper.
  • Polyester filler/epoxy.
  • Wood hardener.

Clean the rot

Use the wood chisel to clear out the rot. You will need to keep digging it till all the loose wood comes off. Trust me, and you don’t need them. It would be best if you were to clean a little extra area near the rot.

Apply fungicide

Fungicide helps the wood to kill off the rot. You need to apply the fungicide if you want the rot spreading to stop.

Apply wood hardener

Wood hardener straight up kills the rot. You should dig some small holes near the rot and apply liquid wood hardener inside them. It will help the wood. Thanks to this, the rot won’t spread, and the near wood will stay strong and healthy.

Apply the epoxy

You can watch some videos online to help you with this process. It’s not that hard. Just wear some safety gloves and mix the epoxy according to the manual inside the box. Don’t be shy while applying. You can always apply more than necessary it’s not always a bad thing. Please make sure not to leave any air gapes inside the epoxy. It won’t have any significant consequences because worms can’t get inside epoxy. But if you are not painting over it, it will look not pleasant.

Sand the epoxy and paint

This is why we said that don’t be shy while applying the epoxy. You need to use a generous amount. You can always sand the excess. It would be best if you sanded the excess. If you don’t polish the surface, you can’t paint it over.

After the sanding and polishing job, take out your paintbrush and paint the epoxy to hide the evidence.

If you want to do a smooth job, you will need to get your hands dirty. You can’t cheap out on using epoxy. It would be best if you filled in more than necessary. Of course, there will be excess dropping out of the hole. But that’s where your sanding and polishing skill will shine.

I hope that this guide was able to help you with your problem. Trust me; no one wants wood rot in their house/farm/barn. It’s an eyesore and makes the house unsafe.
