I have a twenty-five year old home with many doors and trim that were originally stained and lacquered. Over the years, the surfaces have gotten badly scratched and dinged. Trying to repair and re-lacquer them is really not an option. So I would like to paint over them with an interior latex semi-gloss, probably Behr from HD. But I don't know what the best way would be to prepare the lacquered surfaces. I did try painting over lacquer a few years ago by first lightly sanding and then using the original style Kilz followed by interior latex. But some of the latex/Kilz did not adhere all that well and has chipped off in places revealing the old brown lacquered surface underneath. I have seen products that you just wipe or paint on that are supposed to chemically prepar the surface for paint, but these seem to good to be true. Any suggestions would be greatly approciated.
