Review: Best ever for making your own chalk paint! - This is a must buy if your wanting something to make your own chalk paint, it makes it smooth not like some that is clumpy or gritty... It is a huge bag and last forever. Great value for your money
Review: Fool-Proof Chalk Paint - If you're painting with DIY chalk paint, this is the stuff you want to use. I made a quart batch at a time. So silky smooth. Ingredients: 4 cups latex paint 8 TBS calcium carbonate 4 TBS water I mixed the water and calcium carbonate together then stirred in the pain gradually. This turns out fantastic. Truly fool-proof. I know, a tried a Plaster of Paris recipe and got lumps. No lumps here. I painted my closet doors and then sealed them with a couple of coats of polycrylic.

### ⭐⭐⭐⭐⭐ Great product, great price!!
*by H***R on December 29, 2014*

i used this to make my Chalk Style Paint for my distressing projects. it mixes with the paint well and worked just as i expected. i can now get my chalk paint in whatever color i want and at a fraction of the cost. the leftover paint holds up well in a storage containter with a tight lid.
