Our Premier Plus mirror mastic is ideal for high-traffic areas, such as gyms, dance studios and commercial applications. It is currently the only product on the market that can be safely used with acrylic mirrors. It holds firmly yet absorbs movement and bonds to all types of substrates, including drywall, concrete, wood, metals and dry primed surfaces. An environmentally safe product, Premier Plus VOC content is less than 3 gr/L and eligible toward LEED credit. Premier Plus is non-flammable and has very little shrinkage. It can be built out to 2 inches or squeezed down to 1/32 of an inch. It also allows a mirror to be adjusted for perfect alignment up to 12 hours after installation.
