Question about ringdoorbell

i have this wall outside trying to see if doorbell will work on it

will ring doorbell with no drill mount work on it

Hi @puppyrogue. Depending on the exact spot you stick the No-Drill Mount, it could possibly work. There are some spots that appear to have a good amount of surface area that should provide adequate adhesion. You can always use some additional 3M double sided tape for extra security. Just be sure to clean the surface as best you can and allow enough time for it to dry.
