I made counters from left over Puzzle Dollhouse kit pieces and a platform to raise the ready made counter I already own. I have used textured stone spray paint on MDF before and have had no problem but today! I am wondering if it was the weather (cloudy) or the brands (the first can ran out) but can you believe it took two cans of glossy spray paint to cover these three little pieces. I would spray them and then the paint would disappear, no kidding. I then used the second cheaper brand which did stay on but it ran because I sprayed it on too heavy. I can only wait now and survey the results :).
