Last year we installed a kitchen with white CV sprayed in the shop. All was good until the heat came on, and so did the dehumidifier, and with no added moisture in the air, things started moving. As a result, finish started cracking on joints. The problem is, the homeowners are older, there is no good way to re-spray with CV, and there is so much granite on the job. Brushing of the frames in place is the only way out. Doors can easily be done outside. What are the product options and schedules for refinish? Help! Great customer, good kitchen, bad luck.
From contributor M:
Normally if the finish is cracking, it means you may have used too much catalyst. Not sure what I would do. You may be able to prime and paint the cabinets with a good alkyd paint. The doors you may be able to scuff sand and re-topcoat, but check with the manufacturer for topcoating after a year. Are they little hairline cracks over the entire surface?
Now, I'm not saying you don't have some wood movement going on, but I would not be so quick to blame this. Wood is always going to move, and the finish has to be able to move with it. Just the simple action of opening and closing the doors puts stress on the joints, and thus the finish as well.
When CV can't move enough, it cracks, and in my experience it is almost always due to excessive mil thickness. CV is wildly popular for its durability and resistant properties, but that same hardness may make it a poor choice for coating painted frame and panel doors. Sooner or later the joints will crack - it's only a matter of time.
Unfortunately I don't have any advice on what paint to use to refinish. Anything you put over it will probably crack eventually too. Best advice for the future is, use MDF doors for painted finishes... No joints to move and crack. If you must use a wooden frame and panel door, consider a finish that has a little more flex to it.
