Diy chalk paint
I have painted hundreds of projects using everything from AnnieSloan to all the DIY recipes. The best DIY recipe I use is this one:
4 Tablespoons Calcium Carbonate (I order it from Amazon)
1 cup paint (any brand interior house paint & any sheen, since the CalCarb cuts all sheen)
Mix the CalCarb in 2 Tbsp water and then mix into the paint. Stir until smooth like yogurt. Those sample jars of paint are great for small projects but I usually make it by the quart. As long as it is stored in an airtight container, it won't dry out quickly.
Here's a link for the Calcium Carbonate https://www.amazon.com/Pure-Organic-Ingredients-Eco-Friendly-Preservative/dp/B073R11N4P/ref=pd_sbs_121_t_1/140-3172284-1160710?_encoding=UTF8&pd_rd_i=B073R11N4P&pd_rd_r=82c0bd35-a06c-4f12-a557-4fc5d8745d0e&pd_rd_w=pjyqS&pd_rd_wg=PqN5A&pf_rd_p=5cfcfe89-300f-47d2-b1ad-a4e27203a02a&pf_rd_r=VA14EVY6J2DR9M4BJA70&psc=1&refRID=VA14EVY6J2DR9M4BJA70
I always worried about getting the mixture correct and it will sometimes fail if your paint is old. I found Rustoleum chalk paint is always wonderful and can be made into and color where sold at stand alone paint stores. Also very affordable. They also make a clear sealer coat that is more durable and easier than wax. I paint professionally and it's all I use when doing chalk paint.

I paint furniture professionally and I prefer the calcium carbone recipes because it has a longer shelf life once mixed. But the plaster of paris recipe does a good job! BB Frosch is a great option as well!
