I have used Ralph Lauren paint throughout the entire main floor of my house. And I loved it! It looks beautiful and applied well. I used "Hometown Green" in my kitchen, "Buffalo Creek" in my dining room, and "Kilm Red" in my living room. The green and bleu only took two coats, but the burgundy required four. This was because I did not use the tinted primer that is required. I thought I could take a short cut, but it isn't worth it.
I am so happy with the results that I've purchased more of the paint to do my upstairs.
