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.

Clean Up

Uncured material — Wipe up with cotton cloths. If desired, approved solvents, such as ketones (MEK, acetone, etc.), lacquer thinner, or adhesive remover can be used. DO NOT USE SOLVENTS TO CLEAN ADHESIVE FROM SKIN. Take appropriate precautions when handling flammable solvents. Solvents may damage surfaces to which they are applied. Cured material — Chip or grind off surface.
