I am in the process of painting my kitchen cabinets. After a few you-tube videos, I poached a system that worked well for me.
Using small hooks and hangers removes the waiting time or lines from stacking.
- pre-drill into a spot that you won't see on either end of the cabinet (uppers on the upper side, lowers on the lower side, drawers on the lower side)
- screw in the hooks.
- hang on a hanger.
- paint away. In my set up i'm using a sprayer, but doing it with a roller or brush worked just as well.
If you are really picky you can fill in the holes from the hooks later.
