CRL Palmer Mirro-Mastic® in cartridges is the same high quality adhesive mastic that is in the can, but with the convenience of a cartridge. It is formulated for adhering plate glass mirror and acrylic mirror to various substrates, such as drywall, wood, glass, metal, and tile. Mirro-Mastic® is ideal for large mirrored walls, columns, and vanities. It has a one-year shelf life. Mirro-Mastic® may be used with CRL Category Two Safety Tape Film that has been washed with a 70% solution of isopropyl alcohol (IPA). All applications must have permanent bottom support and mechanical fasteners. Palmer Mirro-Mastic® also qualifies for LEED® (Leadership in Energy and Environmental Design) Green Building Rating System™ credit.


COVERAGE: With minimum coverage, one 29 ounce (857 ml) cartridge will install approximately 30 square feet (2.8 square meters) of mirror, and one 11 ounce (325 ml) cartridge will install approximately 12 square feet (1.1 square meters) of mirror.


Product Warning:

Test before using any mastic! Always follow manufacturer's directions on the cartridge. Do not apply Mirro-Mastic to a painted surface, wall covering or treated wood. Palmer Mirro-Mastic® Bond must be used to seal porous substrates. Support mirror at the bottom. Mechanical fasteners must be used for all mirror applications. Such as CRL Mirror Clips, or CRL Mirror Mounting Tape.

Apply both double-sided mirror mounting tape and mastic at room temperature following directions on each package. If the directions do not cover conditions at hand, consult CRL Customer Service. It is the users responsibility to determine the mastic's suitability to a particular application. CRL cannot guarantee materials against mirror spoilage. For ceiling mirror installations refer to the Important Notes section of PM201GL or PM205 mastic in cans. For any questions regarding the use of mastics, contact CRL Customer Service.
