What should you do if there is a gap between a countertop and the adjoining wall?

Question

Quizplus · Accepted Answer

If there is a gap between a countertop and the adjoining wall, you should use sealant to close the gap. If the gap is not sealed, pathogens could grow within the gap and contaminate food items. Also, insects could live and breed inside the gap. If the gap cannot be sealed then the countertop should be far enough away from the wall to allow cleaning on all four sides.
