I recently had someone contact me with questions about painted cabinets. I have copied over my response to them below and I hope it is useful to others. A little background first, though.
Painted solid color cabinetry is very popular now. To get a solid color you can either use paint or tinted varnish. What's the difference? In simple terms, any solid color finish is a combination of pigment (color) and solids content (which is the "armor" that protects the color and gives it a sheen).
We do a lot of repair of the finish on cabinet doors in our
shop for our clients. Very often people complain that the finish seems to have disappeared
in places on the false drawer front and doors under the sink while not having
done so elsewhere (except above the stove which I will deal with in another
blog). There are places on these doors where the finish is worn, dull and/or
blistered. What causes this? Most often it is due to water that has spilled on
the door or transferred from our wet hands when we open the doors.
