Most walls, if they’re long enough and don’t have control joints, will crack. Some people understand that and don’t mind. Others....not so much. This customer didn't want to see the cracks in their brand new walls. We recommended that the contractor sift the larger sand out of Quickset and fill the cracks using a toothbrush, making sure to keep the margins clean. Quickset is the perfect color to match cured concrete so the cracks become unnoticeable to the eye. You would really have to know they’re there to see them.
