Advice on can behind kitchen countertop?
When we moved to our home there were only kitchen cabinets on back wall. We ripped everything out and wrapped cabinets around and I wanted and painted them. My dad had to build 2 to fill in corner and one on top. In doing so he built a bit too big so now we have a gap behind countertop. In some places it's 1/2" other a whole inch. Any suggestions on getting rid of this gap without replacing countertops. Thanks
