Chalk, oil-based or water-based? I find that water-based paint tends to wear off on heavily used pieces.
@blujeanne615 I'd say it depends on the piece of furniture you're using it for and where that item will be located (high-moisture zone vs. a regular area in the house). I do love chalk paint for its ease of use though!
I've had bad luck painting furniture with interior acrylic. Years later, it's still a little sticky, not completely cured. Recently, i was going to pain a bedroom dresser. I went to SW Paints and described my situation. i was advised to buy paint intended for cabinets and drawers. I cost more than HD, but worked beautifully. No stickiness!
