Mirror Mastic

Mounting a mirror with mastic presents 2 separate problems. Fumes from the mastic can tarnish the silver over time. The mirror can accidentally break sending sharp shards of glass flying.

Aluminum Foil Mirror Backing Safety Tape:

  1. Holds the glass shards in place if the mirror brakes or falls.
  2. Protects the silver from fumes that out-gas as the mastic cures.

To achieve these results, the back of the mirror must be completely covered with metal safety tape. We have aluminum foil safety tape available in 6 sizes..
