Outdoor Chalkboard DIY- Weatherproof and Durable! Your kids will love this giant outdoor chalkboard.

Outdoor Chalkboard DIY

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 a perfect addition to his outdoor play space. 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. These materials aren’t weatherproof and wouldn’t last a season of rain/snow. Instead of plywood, I used a Hardie board. Hardie boards are cement board siding with a smooth finish 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 outdoor use. Luckily, black exterior flat latex paint has a flat sheen that closely mimics chalkboard paint. It’s a very durable outdoor paint!

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 there 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.
