Palmer Mirro-Mastic is a high-quality adhesive specifically formulated for securely bonding plate glass mirrors and acrylic mirrors to a variety of substrates. Rigorously tested in both field and laboratory settings, it ensures compatibility with major mirror brands and backing paints. Designed to absorb normal vibrations and accommodate thermal expansion and contraction, Mirro-Mastic provides a durable and flexible hold. It is also suitable for use on reinforced safety backing and meets LEED V-4 compliance standards, making it an environmentally responsible choice. For optimal installation, GLAZE recommends using mechanical fasteners alongside mastic application to enhance stability and security.
