Product Overview

Gunther Premier® Plus Mirror Mastic stands as a high-quality, urethane-based adhesive that has been meticulously formulated to establish a robust and permanent bond between electro-copper-plated glass mirrors or acrylic mirrors and various substrates, including CRL Brand Category II Safety Tape. Its versatility makes it suitable for high-traffic areas like gyms, dance studios, steam rooms, and commercial projects. Once cured, Premier Plus demonstrates moisture resistance, absorbs movement and vibrations, and accommodates thermal expansion and contraction. It can be applied up to 2" (51 mm) for large mirrors or uneven wall installations, and compressed to 1/16" (1.6 mm) for precision mirror installations. For all mirror applications, the use of mechanical support systems is recommended. Additionally, this product qualifies for the LEED® Green Building Rating System™ credit.
