Please use a BONDING primer(oil or latex). Critical. Then, you can top coat it with a durable latex paint.

Don’t go cheap on the paint tools either, the better the quality, the better the paint job. Purdy is an excellent choice for brushes, and a cigar roller is a great choice to roll out a super smooth finish on the primer and the topcoat finish. Remember, the shorter the nap on the cover, the smoother the finish. The higher sheen in the topcoat also needs the shorter nap on the roller cover.

Also, latex paint doesn’t really start to bond well or cure out well for several days, so don’t banging and scratching the doors for about 7-10 days. It will be dry to the touch in a couple of hours, but give the coating a chance to cure before you get rough with it.
