Crack-Pac® Flex-H2O™ is a high solids hydrophobic polyurethane injection resin designed to seal leaking cracks, voids or fractures in concrete or solid masonry. The polyurethane is packaged in the cartridge and an accelerator is packaged in the nozzle. When the two are combined in the cartridge and mixed, the result is a low viscosity, water activated polyurethane. When the resin encounters water as it is injected into the crack, it becomes an expanding foam that provides a flexible seal in leaking and non-leaking cracks.

For Leaking Cracks
FEATURES
- Seals seeping or mildly leaking cracks
- 400% elongation provides a flexible seal for moving cracks
- Can be dispensed with a standard caulking tool
- Can also be used on dry cracks
- Can be used with a reduced amount or without accelerator to slow down reaction time
- Expands to fill voids and close off the back of the crack
- Expanding nature makes it suitable for sealing cracks in solid masonry
- Fast reacting - reaction begins within 1 minute after exposure to moisture; expansion may be completed within 3 minutes (depending on the amount of moisture and the ambient temperature).
- Non-shrinking hydrophobic formula with the elongation and flexibility of a hydrophilic resin
- 20:1 expansion ratio (unrestricted rise) means less material needed
APPLICATION
Suitable for sealing cracks ranging from 1/32" to 1/4" wide in concrete and solid masonry. Can be used to repair cracks in dry, damp and wet conditions with excellent results. Designed to perform in applications where water is seeping or mildly leaking from the crack. Apply to concrete 40°F or above.

INJECTION INSTRUCTIONS
IMPORTANTSHELF LIFE
12 months from the date of manufacture, unopened.
USAGE TEMPERATURE:
In order for components to mix properly, condition to 60°F – 90°F before mixing.
STORAGE CONDITIONS
For best results store in a dry area between 45°- 95°F. Product is very moisture sensitive.
COLOR
Polyurethane - clear, accelerator - green, cured - green.
CLEAN UP
Uncured material – 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.), 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 – scrape or brush off surface with a putty knife or wire brush. Tip: wetting the concrete or masonry surface immediately prior to injection will make cured resin easier to remove.
CHEMICAL RESISTANCE
Very good to excellent against water, most hydrocarbons and alkalis. Poor to fair against ketones, chlorinated solvents and concentrated acids.
DEFINITIONS
Dry Crack: A crack containing no moisture.
Wet Crack: A crack containing moisture (damp or containing standing water). The surface can be dried and will remain dry during the paste-over operation.
Seeping Crack: A wet crack that slowly oozes water. After being dried, the surface slowly becomes wet again.
Mildly Leaking Crack: A crack with a slow trickle of water emitting from its face.
