A Guide to Fixing Small Areas of Rotted Wood

Rotting wood is unsightly and dangerous. In cases where there are small areas of rotted wood, the easy solution is to replace the offending portion. 

In this post, our team from Handyman Connection® of Chicago Central discusses a step-by-step guide to repairing and restoring rotted wood.

Things You Need

Before anything else, you’ll want to secure these following tools:

  • A utility knife and wood chisel

  • A paintbrush and a putty knife

  • A rasp and sanding block

You should also secure these materials:

  • 100-grit sandpaper

  • Polyester filler

  • Wood hardener

Finally, wear a mask during this project to avoid inhaling wood particles. You can use a disposable surgical mask for this project.

The First Steps

Start by removing the rotting part of the wood with your 5-in-1 tool or a sharp tool. Remove all of the rotting and water-damaged parts carefully. Next, coat the area with the wood hardener, and let it sit for a few minutes. After that, mix the wood filler with the polyester, and press it into the recesses of the wood surface using your putty knife.

Shape and Smooth

After a few minutes, the polyester and wood filler mix will begin to partially harden and sag. At this point, use your putty knife to shape and smooth this mixture into the wood surface. You want to make sure that it replicates the removed wood part. Add a second layer if necessary, and shape and smooth it to keep it from hardening completely.

The mixture will start to harden in about 10 to 15 minutes at room temperature. Let it cool and harden once you’re satisfied with how it looks. The last few steps are just sanding the now hard structure, priming the area and painting the newly restored wood surface.
