A:Answer Hi OldMan.
Thanks for asking. The Ring No-Drill Mount will be most effective on even and smooth surfaces. It may be difficult to adhere to brick, shingles, and rough stucco surfaces. It should not be mounted on glass. In all cases, the wall should be wiped clean before attaching the No-Drill Mount.
