1. Prep & plan

Before you get started, make sure the weather is about 40 degrees Fahrenheit or higher. When I did this project, it was about 60 degrees Fahrenheit and sunny, which was perfect for this project.

2. Mix & start filling

Once you have a plan, start mixing the Bondo a little bit and add the hardening agent with a spreader. If you don’t have a spreader, a 1.5-2” putty knife can also work well depending on the size of your knot holes.

3. Repeat & refine

At this point, I wasn’t completely satisfied with the overall finish. While it doesn’t need to be perfect, I did a second coat and repeated the process to fill in spots that I missed the first time.

The wrap up

Overall, I’m happy with this project and think the wood filler gives the deck a more polished and finished look. Plus, it’s less likely you will get a large sliver in your bare foot, Ouch!
