Gunther Premier Plus Mastic – 10.3 fl oz Cartridge (Gray)

Gunther Premier Plus is a premium, high-strength mirror mastic formulated for maximum performance and long-term durability. This 100% solids, low-VOC, isocyanate-free, and asbestos-free adhesive contributes toward LEED® credits, making it an environmentally conscious choice. It is engineered to provide a permanent bond to a variety of substrates, including drywall, concrete, wood, metals, painted glass, and dry-primed surfaces. Safe for use on Category II Safety Backing, it’s ideal for demanding environments like gymnasiums, hallways, and studios.

Gunther Premier Plus compresses to 1/16" for mirror overlays, remains flexible to absorb vibrations and thermal movement, and won’t become brittle over time. It is also water-resistant, suitable for showers and outdoor applications. For optimal results, GLAZE recommends using mechanical fasteners alongside any mastic installation.
