Wood rot repair is paramount and can be done in a DIY way by following the steps below. However, if the damage is too great or the area too big, it may be wise to hire professionals.
When removing rotted wood or board, it is important to not damage the surrounding wood. Use a claw hammer, chisel, or Five-in-one tool to remove the rotted board carefully. Before replacing rotten wood, make sure that the wood next to the removed board is dry.
In a clean plastic container, pour the two-part solution into that container. Use a wooden stick to mix the solution. Use a chip brush to apply the mixture to the wood generously. You can even pour the solution onto the area if the area to be fixed is large or deep.
Wood filler is an essential element of wood rot repair. Before mixing the filler, it is important that the consolidant has had time to rest. Then open the filler container and mix it with a wooden stick using latex gloves.
Once the filler has been properly mixed, it is important to apply the filler to the area that will need to be replaced. Using a putty knife, a generous amount must be applied to the section that will need replacement.
Allow for the filler to dry for a few hours. Once the filler has dried, use sandpaper or sanding block to shape the filler to the size that will allow for the new board to be put in place accurately. This step is critical when repairing rotted wood.
Once the filler has been shaped to size using #80 sandpaper, it is important to let the filler rest for at least 24 hours before continuing to repair wood rot and ensure that the new board will sit in place sturdily.
To finalize the shaping of the area before fixing wood rot, it is important to switch to #120 sandpaper and continue the sanding process until the filler is entirely smooth and ready for the next step.
Painting or staining the new boards is an optional step but highly recommended to ensure that the replacement board perfectly matches the rest of the wooden area. Using a tack cloth, it is recommended to clean, dust off, and dry the area before painting. Once it is ready to paint, apply a primer coat. Let the primer coat dry fully before applying the additional coats of paint. When painting it is always recommended to apply two coats at the very least. This will complete your wood rot repairs project. It is also a good idea if the project is too great to hire professional residential painters.
