I have tried a lot of chalk paint recipes over the years and this is the one I like best. I've used this recipe on kitchen cabinets, metal, upholstery fabric, and fine wood furniture, and never had any issues.
1 cup of latex paint---avoid high gloss/high sheen paint
4 tablespoons of Calcium Carbonate (Inexpensive. I order it online, check Amazon --- https://www.amazon.com/Pure-Organic-Ingredients-Multi-Purpose-Preservative/dp/B07HHJQB4K/ref=sr_1_32_sspa?crid=VLW4CBV9DZ3S&keywords=calcium+carbonate+powder&qid=1566261657&s=hpc&sprefix=calcium+carbonate%2Chpc%2C161&sr=1-32-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExTTc0T0FCQzlWNkJGJmVuY3J5cHRlZElkPUEwMjYyNjA2MlBWRDRTNTRBQ0JZViZlbmNyeXB0ZWRBZElkPUExMDM2NzMwM0YwSERTSEhORzRENCZ3aWRnZXROYW1lPXNwX2J0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU

A few drops of water as/if needed for thinning

This DIY paint mixes well without the constant stirring and lumps encountered with other recipes, it does not dry out quickly as long as it is stored it in an air-tight container.

Good luck painting!
