H.B. Fuller Seal-Kwik™ Mirror Edge Sealer

H.B. Fuller Seal-Kwik™ Mirror Edge Sealer is a safe, proven formula for protecting mirror edges against black edge.  When a mirror is cut or edged, the silver at the edge of the mirror becomes exposed to environmental contaminants such as humidity, salt air, perspiration from handling the mirror, contaminants from some cleaning solutions, or coolants from edging machines. This exposure can start oxidization or "black edge."

Application Instructions

H.B. Fuller Seal-Kwik™ Mirror Edge Sealer - Application Instructions

  1. Clean any contaminants from the edges of the mirror with a mixture of alcohol and water or denatured alcohol.
  2. DO NOT SHAKE THE EDGE SEALER. This is unnecessary and may cause unwanted air bubbles.
  3. Use at 60°F or above. DO NOT FREEZE.
  4. Remove cap and protective plug. Attach dauber to the bottle and pat on a solid surface to saturate tip.
  5. Position wide part of applicator flat against back of mirror with the narrow part up against the edge. With the bottle perpendicular to the mirror back, draw it smoothly along the surface to be sealed. For longer edges gently squeeze bottle for a continuous flow.
  6. Allow about 2 to 3 minutes to dry, depending on temperature and humidity.
  7. Replace cap after use to increase life of dauber.

Tips

Other precautions to help prevent black edge:

  • Use clean gloves when handling mirror.
  • When edging mirror do not back cut or seam the silver side. This exposes more copper and silver.
  • Don’t let the mirror edge become overheated. This affects the adhesion of the protective mirror backing.
  • Clean and thoroughly dry mirror edges after fabrication.
  • Avoid common household and glass cleaners as many contain vinegar or ammonia harmful to mirror backing. Use only an approved and tested mirror cleaner such as Gunther Mirror & More® Cleaner.
