Wooden doors. I painted using water-based white colour. First, I sanded down, I applied two coats, then second coat on the following day. I did not put undercoat or prime as it has been painted before. However, I noted doors still looking like if I applied one coat and the colour is uneven. I wonder if it is because it was previously painted with oil base paint, I do not if it was oil based. I want it to use a product called Zinsser bulls eye 1 2 3 primer-sealer stain killer then apply another coat of water based white paint, would this solve the problem? Do I need to sand it again?
