Especially when spraying finishes, it’s common to get too little finish on the edges of cabinet doors and drawers. If these doors and drawers are installed under a sink in a kitchen or bathroom, splashed water will break through the thin finish, causing it to peel. There’s rarely anything you can do to fix this damage short of stripping and refinishing.
So it’s important to get enough finish on the edges to begin with.
The most common method of spraying doors and drawers is to lay them flat and spray from above. Typically, the edges are sprayed at a 45° angle. This doesn’t get enough finish on the edges.
The first pass on the edge should be made all the way around at a 90° angle to the flat, horizontal surface. Then another pass at 45° should be made to hit the routed or shaped edges well. Finally, apply full passes perpendicular to the top surface.
Do this with each coat.
