Application Instructions
  • Maintain surface temperature between 40°F and 90°F (4°C and 32°C) during Installation and for 24 hours thereafter. For expansion joints or perimeter sealing, the ratio of the joint width to sealant depth should be roughly 2:1.
  • Apply to clean, dry surfaces free from dirt, grease, and existing sealant. For deep joints first install polyurethane or polyethylene foam backer rod.
  • Metal, glass and plastic surfaces should be cleaned by mechanical or solvent procedures. Simple detergent or soap and water treatments are not acceptable. In all cases where utilized, solvents should be wiped on and off with clean, oil and lint free cloths.
  • Cut nozzle at angle to desired bead size. Use masking tape on both sides of joint to allow for easy clean up. Fill joint completely and tool to desired thickness immediately before a skin forms.
  • Remove masking tape immediately after tooling and wipe any sealant off the face of the veneer. Skins over within 10 minutes. When sealing limestone or other porous stone, conduct small test area to verify non-staining as variations exist.

Note: It is the sole responsibility of the installer to determine the suitability and compatibility of the product for the intended application.

  • Clean-up: Clean-up or remove from unintended areas before sealant skins over. Wipe hands with dry cloth to remove sealant. Wash with soap and water.
  • Curing: Protect from traffic or water exposure for 24 hours. Swimming pool applications or submerged applications – use polyethylene backer rod or tape and allow 14 days to cure before filling pool. Fully cured sealant is non-hazardous.
  • Certain stone surfaces may be stained when sealed with a colored sealant, test a small area prior to use to determine suitability.
  • Temperature Range: -62°F to 400°F (-52.2°C to 204°C) continuous use. -62°F to 450°F (-52.2°C to 232°C) intermittent use.
  • Maximum joint depth should not exceed 1⁄2" (12 mm) thickness (use backer rod for deeper joints).
  • Maximum joint width is 1" (25 mm), minimum joint width is 1/16" (1.6 mm).
  • Not for use in aquarium applications or where subject to abrasion, abuse or wear.
  • Not paintable.
  • Not for use on building materials that may bleed oils, plasticizers or solvent materials (e.g. impregnated wood, oil based caulks).
  • Not a structural glazing adhesive.
  • Not food safe.
