Crack-Pac® Injection Epoxy

The Crack-Pac^® injection epoxy is designed to repair cracks in concrete ranging from 1/64" to 1/4" wide in concrete walls, floors, slabs, columns and beams. The mixed adhesive has the viscosity of a light oil and a low surface tension, allowing it to penetrate fine to medium-width cracks in dry, damp or wet conditions with excellent results. Resin is contained in the cartridge and hardener is contained in the nozzle.

Key Features

Dispenses with a standard caulking tool, no special dispensing tool needed
Clean and easy to mix
Seals out moisture, protecting rebar in the concrete from corrosion and flooring from moisture damage
Chemically bonds with the concrete to restore strength
Non-shrink material resistant to oils, salts and mild chemicals
Meets the requirements of ASTM C881, Type I, Grade 1, Class C

Applications

Suitable for repair of cracks ranging from 1/64" to 1/4" wide in concrete walls, floors, slabs, columns and beams
Can be used to inject cracks in dry, damp or wet conditions with excellent results. Not for use in actively leaking cracks.
In order for components to mix properly, the resin and hardener must be conditioned to 60°F–80°F before mixing

Color

Resin - blue, hardener - clear, mixed: light amber. The color of epoxy will change from amber to blue during the cure process and then fade back to light amber within a few weeks of installation.

Storage Conditions

For best results, store between 45°F and 95°F

Shelf Life

24 months from date of manufacture, unopened

Clean Up

Wipe up with cotton cloths. If desired scrub area with abrasive, waterbased cleaner and flush with water. If approved, solvents such as ketones (MEK, acetone, etc.), laquer 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.
