I have used Websters chalk paint powder in regular paint. I was not impressed but the cabinet I was painting was stained very dark so maybe it needed a coat of primer first. It bled through. Annie Sloan is about $40 per quart and has limited colors. That's the only reason I bought the Websters.
I don't care for the distressed look, which is what a lot of chalk paint users are going for, so I'm going to stick with regular paint.
