Tips for keeping your deck pristine

Once you’ve repaired or replaced your damaged or unsightly deck boards, be sure to keep up with your deck’s maintenance and care to prevent future damage or cosmetic issues.

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!
