Warped Cabinet Doors9/20
We have recently used water based primer and PPG Breakthrough paint on 4 major cabinet jobs. We have experienced several cabinet doors warping (as many as 30 doors) on all 4 jobs. We also experienced de-lamination of side panels & shelving. There was also an issue with the paint cracking atop the caulking.
The doors were all of different styles and shapes. We had shaker doors, raised panel doors and more. We used first quality American wood for our doors which some were poplar and some were maple. We also used 2 different manufacturers for the cabinet doors.
We sought advise from our PPG store and representative on the proper primer to use with the Breakthrough and went with their suggestion.
The only common threads with these issues are the PPG Breakthrough and the primer. Anyone else out there with similar issues?
I've used Breakthrough on two jobs that required really dark colors because at the time GF didn't have a dark base for pigmenting. So far the jobs have held up well. I used Zinnser shellac primer then 3-4 coats of the Breakthrough. Looked great and haven't heard a peep out of the clients. GF has since come out with a new dark base so I'll stick with them as I use their products almost exclusively.
The warping could an issue of moisture content of the wood pre-finishing or a door construction issue. Breakthrough is technically a "softer" more flexible finish but the caulking has to be absolutely dry before finish is applied over it. I always leave my caulked doors overnight.
In the past we've had issues with Poplar doors because of movement and bleed through etc..we use mostly Alder or Maple at times for doors/drawers now.
Unless you did really thin coats or didn't prep the doors correctly I don't think the
