So you’re here because you want to paint some melamine with chalk paint, but you are not sure how well it will work. Well, there is only one way we can figure this out for sure, test it! I grabbed a melamine sample square and a tin of Rustoleum chalk paint and did some painted. I then tested how well the paint had stuck to the melamine.
Painting Melamine With Chalk Paint
As is said before I will be using Rustoleum chalk paint to test whether you can paint melamine. Below you can see the melamine sample I will be painting.
On one side of the melamine, I will lightly sand using 120 grit sandpaper. This is to test whether sanding the melamine makes a difference to adhesion. On the other side, I will just paint straight onto the melamine.
So here is the melamine after it has been painted with chalk paint. So far so good, the paint has gone on really well. It has covered the melamine well, even with just a single coat of chalk paint.
After the Paint Has Dried
I left the sample for around a week to allow it to fully cure and properly harden. This is what it looked like.
You can see the finish isn’t perfect but that is more on me than the paint. I wasn’t aiming for perfection, rather I was just trying to test whether it would work.
What I would say is that applying the chalk paint with a roller worked well. The roller left a little bit of texture in the paint but this blended in really well to the melamine surface texture.
Scratch Testing Chalk Paint on Melamine
Now comes the real test of chalk paint on melamine, I will attempt to scratch the paint off the melamine to see how well it has adhered.
For this test, I grabbed a large price of rough-cut c16 timber and rubbed it across the melamine surface. This is a really tough test to see how well the paint has adhered to the melamine.
I feel that rough cut c16 timber is a good test medium as it is not too hard but not too soft. If I used something really hard like metal then not much would stand up to it and the test would be pointless.
On the other hand, if I used something too soft it would never scratch anything and again it would be pointless.
You can see a huge difference here between the sanded and unsanded sides of the melamine. The unsanded side has come off really easily, I think it is fair to say this hasn’t worked at all.
If you are going to paint melamine with chalk paint then you definitely need to sand it first. I would actually recommend going a step further however and sand the melamine and then prime it with something like Zinsser BIN primer.
