For optimal results, and to achieve all the wonderful properties of chalk/mineral paint, it is recommended to use a FLAT FINISH paint.
Any desired sheen can easily be achieved in the finishing/sealing stage.
BB Frösch Paint Transformer will help eggshell, semi-gloss and high-gloss paint bond, but the other chalk/mineral-paint features like distressibility will be compromised.
If you aren’t worried about distressibility, and simply want a high sheen paint that will bond, we recommend adding extra powder. You can double, or even triple, the amount of powder! This will increase bonding properties as well as other desirable properties of chalk/mineral paint.
