I used Zinsser shellac clear as a sealer over maple cabinets. I thought it was dewaxed, but it's not. I'm almost done with this project and topcoated most of it with Agualente and it looks great. The finish is sticking fine as far as I can tell. Any problems later? Should I just spray the doors the same way and hope for the best... and do something else next time?
From contributor C:
Have you done any simple testing to know for sure how good the adhesion is? If not, try taking some duct tape and pressing it down on the surface and then pulling quick and hard to see if anything comes loose. Then you can also do a crosshatch test - take a razor blade and measure tape and cut lines 1" long through the coating and then the opposite way (making what looks like a grid or large X and O game) every 1/16", 10 lines each way altogether, and then use good cellophane tape or masking tape the same way you do for the duct tape and view the results. This will let you know if you have anything to be worried about in the future as to delamination/flaking/etc. You may have gotten lucky but you never know.
If more than 10% comes off on the hatch test, then it is not acceptable adhesion for my concerns. Definitely do something different next time. Zinnser seal coat.
I have not had any problems using fresh solved blonde so far, but if it was a critical application, I would use the seal coat unless absolutely necessary to keep the color lighter and not as orange/brown looking as the seal coat is over very light woods.
