Painting Chalkboard Paint on Glass

I try to avoid using paint on glass unless it’s glass paint, because latex and acrylic paint chips and washes off easily.    Because there are so many uses for chalkboard paint on glass, I wanted to do some testing on pieces of glass that I really didn’t need, instead of messing up a nice 6-pane window or something.

I’ve read that spray chalkboard paint works better, I’ve read that chalkboard paint in a can works better.  There was no better way to find out than to give them both a try myself.

I had a couple piece of glass laying around from the inside of picture frames that I used for other projects.  I love refinishing frames because it’s a quick and easy way to update an area of your home for cheap, cheap, cheap.  Here’s how I used a picture frame in my entry way.  I also put together a bunch of small thrift store frames to make this gallery wall.

I tested Krylon blackboard spray paint and Rustoleum blackboard brush-on paint.  (For the remainder of this post, the spray chalkboard paint will be on the left and the brush-on paint will be on the right of each image.)  Each piece of glass got three light coats of paint.  The first difference I noticed was the glossiness of the spray paint; I wasn’t liking it already.

After drying for 24 hours, I conditioned them by rubbing a piece of chalk on it’s side over the chalkboard.  Even as I did this, I could feel a significant difference between the two.  (Spray is on the left, brush is on the right.)

You know the type of blackboards that your chalk sort of skids over, without catching as much of the surface as you want?  That’s what the spray paint felt like.

Keep in mind, both of these did, and will chip, when something sharp scratches it.  I used my fingernail to test this on both.  The sprayed on paint scratched very, very easily; it was a little more difficult to scratch off the brush-on paint.

 

When erasing, the chalk on the sprayed piece of glass left a faint residue, while the chalk on the brushed on piece of glass erased completely.
I’m sure you can tell by now which paint I ended up using for this little frame.  The winner is:  the brush-on chalkboard paint!  It gives a matte finish, which is perfect for a chalkboard.
I’ve also used both of these paints on other surfaces such as wood and walls, and I find that the Rust-Oleum Chalkboard Paint* is far superior on all surfaces.

  1. I’m so glad you shared this. I’ve only used the brush on, but I purchased some spray-on to try. My mistake with the brush-on was putting it on too thick and the first time, I did not know to cure it.

    I accidentally, by trying it, learned that rubbing alcohol will clear off any lines and smooth it out if you go crazy with it like I did.

    Thanks again for sharing!

    1. I’m so glad you shared the tip on the rubbing alcohol – I didn’t know that! I’m sure spray paint is ideal for some projects, but overall, I almost always reach for my can of chalkboard paint.
