Palmer Products began manufacturing mirror adhesives in 1933 with Palmer Mirro-Mastic. They now manufacture two high quality adhesive mastics for mirror, Palmer Mirro-Mastic and Palmer QwikSet . Both are formulated for adhering plate glass mirror to various substrates such as drywall, wood, glass, metal or tile and have been field and laboratory tested for compatibility with all major brands of mirror and backing paints. Mirro-Mastic can also be used on acrylic mirror as well as reinforced safety backings and has been field and laboratory tested with all major brands of those products as well. Neither Mirro-Mastic nor QwikSet will damage mirror silvering. Mirro-Mastic is ideal for large mirrored walls, columns and vanities. QwikSet is ideal for mirror-to-mirror overlays, beveled strips, and mirrored furniture. Application information for both products is available on Palmer's website www.mirro-mastic.com.
