Trendy counters. One countertop manufacturer heralds concrete as “practical artwork” that requires “virtually no maintenance other than normal cleaning.” Another describes
limestone as “velvety smooth” and “unique.” CR’s tests, however, found concrete to be fragile and susceptible to scratches, chips and hairline cracks. As for
limestone, it might start out smooth, but CR’s wear tests left it scratched, stained and dinged. Smarter option: If you crave the stone look for your countertops, granite or quartz should prove more rock solid.
