I had new quartz kitchen counters installed yesterday. On one side by the cooktop there is no gap between the counter and backslash. The other side, by and behind the sink, was left with a gap between the counter and backslash! One side looks great and other looks unfinished!
My concern is that water can spill easily from the faucets to that area and seep behind into the gap and cause water damage or mold to grow in the pine wood cabinet below.
How do I resolve the gap issue? Should I grout the gap using a color close to the (tan) quartz? Should I caulk it with kitchen/bathroom caulk? Or using clear, or white, preferably tan, silicone to fill gap? I would have to then do all lines between the counter and backslash in all areas to accomplish a consistent look: would that be OK?
