Repair Rotten Window Joists

Rotten window joists or jambs should be repaired as soon as possible to avoid further damage to the window and also to prevent damage to your home's interior. The joists or jambs are partially exposed on the exterior of the home and can begin to rot, particularly when the paint has worn off. The bottom of the window is generally the most exposed and also the place where the largest amount of moisture collects. You can repair rotted areas with a two-part wood epoxy. Does this Spark an idea?

Instructions


1. Scrape the paint from the rotted area of the window joist or jamb, using a paint scraper.


2. Clean out the rotted area with a wire brush to remove any loose rotted pieces and other debris.


3. Sand the area around the rotted wood with medium-grit sandpaper to further prepare the area for the epoxy repair.


4. Brush a light coat of epoxy primer over the rotted wood, using a nylon brush. Allow the primer to sit for approximately 15 minutes or as directed on the package.


5. Fill the rotted area with epoxy filler using a putty knife to pack it tightly in place. Allow the filler to dry for 24 hours.


6. Sand the epoxied repair with medium- and fine-grit sandpaper until the repair is flush with the joist or jamb. Always sand with the wood grain.


7. Prime and paint the repair with a paintbrush. Allow at least four hours for the primer to dry before applying a top coat of paint.
