If you have a kid, you’ll know that chalk is always a huge hit. My son adores playing with chalk and I think he could spend all day hanging out in the backyard drawing pictures. The only problem? Our patio is too small for him to really be able to do much on it! So, we decided to create our own solution by building a huge outdoor chalkboard to hang on our fence. It looks great, it’s held up beautifully, and he plays with it all the time!

How to Build an outdoor Chalkboard

Materials:

• 4ft by 8ft piece of plywood (I’d recommend exterior, pressure-treated plywood!)
• Three pre-primed 8-foot 1x4s (You can get cedar or pressure-treated wood if you want it to be extra weatherproof, but we just used whitewood – it will hold up fine if you paint it)
• One 8-foot cedar 2×4 (Used for mounting to the fence)
• Primer
• Paintbrush & paint rollers (This is my favorite brand of paintbrush)
• Chalkboard paint
• Paint or stain for frame (This is what I used)
• Drill/Driver
• Wood glue
• Clamps
• Screws (1 1/2″ and 3″)

Prep + Painting

First, we picked a spot – we’ve got an area of the fence that’s nicely lined with trees and gets lots of shade. Jackson already plays over there a lot, so it was perfect!

We started with a large 4X8 foot piece of plywood – something like a concrete backer board would be a more weather-proof option, but since we were painting this, we knew it would hold up fine. (Update: when we moved from this house two years later, the chalkboard still looked as good as new, and we just used plain non-pressure-treated plywood!)

We started off with some primer. Lots of it – I did three coats of primer on both sides of the board, and we bought pre-primed boards for the frame. We went ahead and cut the boards for the frame at a 45-degree angle on both sides before priming using our miter saw (don’t know how to use one? Here’s my tutorial!), then we made sure to get the edges of all the boards particularly well because that’s a place water might seep in.

Once it was all primed, it was time to paint. We spray-painted the frame pieces with yellow paint and used chalkboard paint on the big board. Be sure to check the directions on your paint if you are trying this for yourself – I never realized chalkboard paint requires a full 24 hours between coats!

Also, a quick note on the chalkboard paint – it’s technically not meant for exterior use. I’m sure with some searching and creativity, you could find an option that is meant for outside use, however we had zero issues with this holding up over time!

Assembly

Once everything was painted, it was time to assemble it!

We applied wood glue to the frame pieces, then clamped them to the front of the outdoor chalkboard, as shown above. Then, we drilled into the board from the back using 1 1/2″ screws. This way, we don’t have any screws showing on the front of the board!

Once that was taken care of, all that was left to do was hang it.

We centered the outdoor chalkboard on a section of fencing so that each end would be able to be attached to one of the posts. For added stability, we hung two cedar boards as spacers in-between the posts, as shown above. We stuck with cedar for this part, since these boards are the only ones that are unpainted and fully exposed to the elements.

We aligned the outdoor chalkboard exactly where we wanted it hung, then used black outdoor screws to attach the boards directly to the posts and supports. We just drilled into the black part of the chalkboard, so they’re barely visible.

After it was hung, we took a cute little hook (like this one) and a metal bucket and hung them nice and low on the chalkboard to hold all of Jackson’s chalk! The bucket is meant for potting, so there’s a small hole in the bottom which will be perfect for allowing water to leak out if it rains.

We got it all hung up and ready one day when Jackson was taking a nap, so when he woke up…

… let’s just say he was excited.
