Madigan made... tips for using chalkboard paint on glass.
Your comments after my recent post about mini chalkboards sparked this topic.
Several of you mentioned that you did not know you could paint glass with chalkboard paint.
Well, I'm here to tell ya:
Yes, you can use chalkboard paint directly on glass!every month, the paint is holding up fine. (even after our little nephews are over and doodle on the chalkboard, too)
But, there are a few pointers and tips I have for you to prevent the paint from chipping or peeling off the glass.
Of course, read the instructions on the chalkboard paint carefully. First, make sure it can be used on glass. (The spray paint I used states that it can be used on glass, but to test first. I'm not sure if the brushable paint in the can states that or not.)
Here are a few key tips if you want to try to paint glass:
1. Use spray paint.
That is what I used. I'm not positive, but I'm guessing you will get better adhesion with a spray paint compared to the kind you can brush on. I also like not having brush strokes on the finish.
2. Clean the glass REALLY well.
Paint will not adhere very well to dirt or grease. I use isopropyl alcohol to clean any glass or porcelain surfaces that I'm trying to paint.
3. Lightly sand.
I'm really not sure if this step is critical, but I gently rubbed fine steel wool on the glass. (and cleaned the glass again afterwards)
3. Use multiple, light coats.
You do NOT need to prime with chalkboard paint. In a well-ventilated area, spray the glass. The instructions on my can said to use at least 2 coats of paint. Honestly, I put 5-10 very light coats on all the chalkboards I made. Allow a few minutes of drying time between coats.
4. Let the paint cure.
Krylon advised waiting at least 24 hours before using the surface. It's hard, but be patient! Wait the instructed amount of time that comes from the manufacturer before touching it.
Using the side of the chalk, rub chalk over the whole surface prior to the first use. (this will prevent any 'burned in' images)
And it is important to note that I used real glass frames. Some of the 'glass' in frames these days can be a heavy Plexiglas or plastic. I am not sure how well the chalkboard paint will work on plastic.
I've had chalkboard paint peel off plastic and I told you about it in this post. Stick with glass.
Which of these steps is the 'most important'?
I wish I knew... So I'm going to say: All of them.
I don't anticipate that my big chalkboard will last forever. I expect I will need to recoat the surface at some point.
I'm certainly no expert. So if you do try (or have tried) to use chalkboard paint on glass... share your experiences here!
We all can learn tips from each other.
