Create a Chalkboard Wall in 3 Easy Steps

by sradmin on September 14, 2015


(Takes less than a day – with a NO VOC paint!)

Step 1: Prep

  • Lightly sand the wall (220 grit will work nicely) and then wipe down with a degreaser. Once dry, tape off the section/shape you want your chalkboard to be.


Tips: Use a level to be sure you’ve got straight lines & use good quality painter’s tape to keep those lines clean!

Step 2: Mix Up Your Miss Mustard Seed’s Milk Paint with Bonding Agent.

If you already know how to properly mix Milk Paint great! If not, watch this video:

Then follow these further instructions:

Bonding Agent gets added at the very end (once you’ve reached the right consistency and have let the paint sit for at least 10 mins) It is added in a 1:1:1 ratio; that is, 1 part milk paint powder to 1 part water to 1 part Bonding Agent. Mix well.

Now, one of the many fabulous reasons for using MMSMP to make your chalkboard is that you can choose any of the colours (provided you feel the chalk will show up well enough on it) For example, Flow Blue makes a beautiful chalkboard:

Unless your heart was already set on a traditional black chalkboard choosing your colour may very well be the most difficult part of your project!

Tips: Because Bonding Agent thins out your paint it is a good idea to mix it up a little thicker then you might usually – this will give you better coverage! Also, mixing in a Mason Jar is so handy! Especially because you just screw on the top to keep the paint fresh in between coats.

Step 3: Paint ‘Er Up!

You may have heard it before but the first coat of milk paint with bonding agent can look a little… well, like it’s not working, or you’ve done something wrong. Don’t worry the second coat will look much better!

When you are doing your first coat, especially, be sure to work in small areas and go back to check for drips as they can appear even after you are finished painting a section. The paint may look streaky, drippy and uneven, again, don’t worry.


Wait 2 hours, then do your next coat. Wait 2 hours again, and before your final coat do a light sanding over your whole surface – just to be sure it is nice and smooth. It really should be just a quick light sanding with a 220 grit or higher paper to get rid of any lumps or bumps. After this sanding I don’t worry about wiping it down as the amount of dust should be minimal– if you feel it is awfully dusty and you don’t want to paint over it just wipe with a dry cloth.

Paint your 3rd and final coat.


Tips: Mix, mix, mix!!! Milk Paint is all-natural, that means it doesn’t have chemicals in it to suspend the pigments and they can tend to separate. Be sure to mix your milk paint every few minutes while painting and especially before you begin each coat. Also, paint your first coat in strokes that run left to right, your second up and down, and your third left to right again. This helps to prevent brush strokes (although you don’t have to worry about those too much with milk-paint provided, especially, if you have used a decent-quality paint brush)


Your chalkboard should perform and last very well! I like to give my milk-painted chalkboards at least 12 hours before I clean them with a damp rag. Never let a lot of water just sit on them but certainly feel free to erase with a regular chalkboard eraser and clean with a dampened rag whenever you like! No need to “season” with chalk unless that’s the look you’re going for.
