Dryrot is one of the most common problems you may encounter in your home especially in exterior wooden trims. However, there are two methods that you can use to deal with this issue effectively. You can either replace the wood completely to eliminate rot, or repair the damaged sections. But, both the methods require a significant amount of carpentry skills. Improper replacement of the dead wood can cause a significant amount of damage to your trims and any improper trim replacements near the windows can lead to insulation problems. Similarly improper repair can lead to damage and also promote decay causing further issues. As a result, it is advisable to seek expert help when it comes to dealing with dryrot.
Preparing the wood for repair
The most important part of the process involved in dryrot repair is the preparation of the wood in a suitable manner. You will need to use special patching products to make the wood resistant to moisture. The patches are generally prepared using epoxy compounds that are mixed right before usage. Before you apply any of the patches, it is also necessary to clean the wood surface adequately. This is generally done by removing the decayed portion of the wood until you find a sound layer by chiseling.
In some cases, this is not possible due to extensive decay. In such situations a wood product known as a consolidant must be used. This product impregnates the wood and reinforces the fibers while adding strength to the infected wood. However, you need to make sure that the wood is dry when applying the consolidant
