How to Properly Fix Rotting Wood Surfaces

Wood is a beautiful material and remains popular for many things like siding, windows, and floorboards to name a few. But it’s also the most vulnerable to moisture and water damage and has less elemental resistance overall. Rotting wood isn’t pretty to look at, and it’s important that you address it immediately before it becomes a bigger problem. Handyman Connection of Knightdale discusses how to properly fix rotting wood surfaces.

Wood Surfaces

Necessary Tools and Materials

You need a few things to properly repair a rotting wood surface. For the materials, you want to get three things:

  • A polyester filler
  • A wood hardener or consolidant
  • Sandpaper with 100 grit

For the tools, you want to get the following:

  • A rasp
  • A putty knife
  • A sanding block
  • A utility knife
  • A paintbrush
  • A wood chisel

The First Step

The first thing you want to do is remove the rotted piece of wood. We recommend using a sharp tool or a 5-in-1 tool to safely remove it. After removing it, coat the area with your wood hardener. Finally, you’ll want to mix the wood filler with polyester and press it deep into the recesses of the surface with your putty knife. It’s important to note that you can actually use epoxy instead of the polyester mixture; WoodEpox, for example is a good alternative. However, temperature does affect epoxy performance and heat actually makes it sag. So generally, polyester is the better material to use.

Shaping and Smoothing

Once you’re done filling the recesses with the wood filler, it’s time to shape it into place. We recommend you use your putty knife or a small chisel to carve the filler in place, and make sure to fill the entire space carefully. If necessary, you may add another layer of polyester mixture of the first one was insufficient. Just make sure to even out the surface.

Let the mixture settle and harden, and once it does, all that’s left is to apply the finishings. If the wood originally had paint on, we recommend you let the wood filler settle for at least a day before repainting just to be on the safe side.
