Product Warning:

Test before using any mastic! Always follow manufacturer's directions on the can. 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 with 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. If you have questions concerning the use of mastics, call CRL Technical Sales for more information.
