How to Patch Split Wood Siding


Here’s a question from our 3/23/2019 Today’s Homeowner Radio Show.

Ron from Michigan says, “We’ve lived in our 40-year-old house for four years. It has vertical cedar siding planks. Many are split, and knots are falling out. Can I use caulk to seal splits and cracks? What do I use to plug knotholes?”

We say test out a few areas with Bondo or an acrylic latex caulk so that it matches the siding. Then use sawdust and glue to put it back in place. A stain would need to be put back on afterward.
