Outdoor Chalkboard DIY- Weatherproof and Durable!
About a year ago I built Indigo this sandbox with a roof. I’m happy to report that he loves it and it held up beautifully through our NY winter. Indigo has really gotten into drawing lately so I thought a chalkboard would be perfect. I attached this Outdoor Chalkboard DIY to the back of the sandbox, but it could just as easily be secured to a fence.
Many of the Outdoor Chalkboard DIYs I’ve seen use sheathing plywood and chalkboard paint. This materials aren’t weatherproof and wouldn’t last a season of rain/snow. Instead of plywood I used a Hardie board. Haride boards are cement board siding and they’re very durable! They’re used as siding on houses because they’re low-maintenance and long-lasting. At $12-$14 per board, they also make an affordable DIY chalkboard!
As for the paint, the chalkboard paint that’s sold in stores isn’t intended for exterior use. Luckily, black exterior flat latex paint has a flat sheen that closely mimics chalkboard paint.
This Outdoor Chalkboard DIY can weather the elements for years of fun!

I leaned the Hardie board up against the sandbox posts from the back. Then I cut 2 pressure treated 2 x 4s the length of the sandbox posts. I screwed the 2 x 4s into the top and the bottom of the Hardie board on the back side.
If you’re attaching the chalkboard to a fence- use construction adhesive to adhere the board to the fence. Then, make a frame using the 2 x 4s. This will ensure that they’re are no visible screws through the chalkboard.
After the Hardie board was secured, I painted it with the latex paint. I also added a hook to hold the chalk bucket.
