including coating substrates with mastic manufacturer's special bond coating where applicable.
3.3 INSTALLATION
A. General: Install mirrors to comply with mirror manufacturer's written instructions and with
referenced National Glass Association (NGA) publications. Mount mirrors accurately in place in

"Installation Techniques Designed to Prolong the Life of Flat Glass Mirrors."
B. Provide a minimum airspace of 1/8 inch between back of mirrors and mounting surface for air
circulation between back of mirrors and face of mounting surface.
C. Install mirrors with mastic and mirror hardware. Attach mirror hardware securely to mounting
surfaces with mechanical fasteners installed with anchors or inserts as applicable. Install
fasteners so heads do not impose point loads on backs of mirrors.
1. Aluminum J-Channels: Provide setting blocks 1/8 inch thick by 4 inches long at quarter
points. To prevent trapping water, provide, between setting blocks, two slotted weeps not
less than 1/4 inch wide by 3/8 inch long at bottom channel.
2. Install mastic as follows:
a. Apply barrier coat to mirror backing where approved in writing by manufacturers of
mirrors and backing material.
b. Apply mastic to comply with mastic manufacturer's written instructions for coverage
and to allow air circulation between back of mirrors and face of mounting surface.
c. After mastic is applied, align mirrors and press into place while maintaining a
minimum airspace of 1/8 inch between back of mirrors and mounting surface.
