I bought from this company bc my daughter has health concerns and has MCS. We painted her new room cement floor with their cement paint. We choose a lovely yellow. I am very pleased. A second coat, as recommended, will be best so I'll do that today. The good news is, light odor while painting, then pretty much odor free after drying. My daughter was in the room several days later and had no negative reaction. I'll buy from them again. Additionally, MyChemicalFreeHouse recommended as their #1 pick, and that's what lead me to this company. Yay for companies that care about environmental toxicity and are making a difference!
