I've been using these on a brick wall for a few months now and they work great. Follow the directions, make sure the surface is dry and dust free (brick test only) and they work great! Seriously follow the instructions. How I use them on a brick: Find the flattest part of the brick you want to hook. j. Wipe the stone with a dry cloth to minimize surface dust. Read lane signs! (Fix the strip on the hook. Side of the wall on the brick. Press firmly for 30 seconds.) Wait 1 hour. For real. Do something constructive for 1 hour. Hang anything <0.5lb (These hooks are only rated for 0.5lb). , and break whatever you had hung up and/or fell on.
