I am trying to help out an existing client of mine who has purchased factory made cabinetry from an upper end manufacturer. Her cabinets are finished in an ivory color catalyzed finish with a mocha glaze. The problem is that the amount of glaze from door to door varies from heavy to almost no glaze at all. The manufacturer has tried three times to change out doors, drawers and panels with no luck. They have finally agreed to pay a third party to "even out" the glazing.
My question is, what steps should I take to ensure there is no future adhesion problems? My thoughts are to scuff all surfaces with 220 add a light amount of glaze to areas as needed and top coat with clear. The mfg is sending out all the products so compatibility should not be an issue. Any input would be appreciated.
From contributor D:
Most likely there is a clear coat applied over the glaze. This means you won't be applying new glaze directly onto the old glaze. This may or may not allow you to achieve the look you're after. Scuff sanding the surface is a good idea, but even better in my opinion would be to lay down another coat of clear before you begin glazing. We do tons of glazing with catalyzed products, and the only way we've found to get bullet proof adhesion is to have the glaze sandwich (seal/glaze/seal) be as fresh as possible; as soon as 1/2 hour and no more than 1 hour between each process. No matter what you decide to do, you must do a test piece and scratch test for adhesion before you proceed with the whole job.
If they plan on paying a third party to do a fix you should have them present you with new doors and drawers and whatever it would take for you to do the job correctly. Trying to even out a project that has dark glazing means that everything has to turn out dark. That look might be too dark for the customer/client.
Just because they are going to supply you with the same materials they use at the factory says nothing about the finishing window. Iíd be willing to bet that the window is closed now, and anything you put on top of a coating thatís gone through the cure time, just might create a bigger problem.
