I have contractor to install quartz top on my kitchen cabinet. After installation there is a 4 to 5 mm gap between my kitchen sink and the quartz top. Is there any way to solve this problem? As for now, the big gap is ‘close’ using silicone glue and it’s look ugly. I worry the silicone glue would trap dirt and mold easily after sometime. I wonder what I can do to solve this problem.
