Installation

  • Surfaces to receive adhesive must be clean.
  • Base material temperature must be 14°F or above at the time of installation. For best results, material should be 14°F (–10°C) to 80°F (27°C) at time of application.
  • To warm cold material, store cartridges in a warm, uniformly heated area or storage container. Do not immerse cartridges in water to facilitate warming.
  • Mixed material in nozzle can harden in 3–4 minutes at temperatures of 70°F (21°C) and above.
  • Use only Simpson Strong-Tie mixing nozzles in accordance with Simpson Strong-Tie instructions. Modification or improper use of mixing nozzle may impair AT-XP adhesive performance.
  • For full instructions, see Adhesive Anchoring Installation Instructions.
