Plan Ahead and Test
My experience with milk paint was not good, but perhaps it's my fault. I saw a YouTube video where they mixed flag red and black iron. The resulting color was exactly what I was looking for...or so I thought. After carefully mixing and applying on my bare wood project, it looked good wet but not at all what I wanted after it dried. I applied both Varathane finishing wax and Minwax Polycrylic as a topcoat, but neither did the trick. Perhaps if I had wax from the Real Milk Paint Co it would have looked better, but I didn't have time to wait for a shipment. I also tried several other mix formulas trying to get my desired color, but no joy. Milk Paint might be a great product if you can get the color you want and use their topcoats, but it didn't work for me.
