CPP™ Gel: Crack Injection

• Easily dispensable from most caulking guns.
• Rapid initial set time (approx. 3 hrs) at room temperature (75°F).
• Moisture is insensitive and may be used on damp surfaces (SSD).

• Ideal bonding agent for most materials including concrete, brick, wood, stone, block and other substrates
• May be used as an adhesive or filler
• Capping paste and injection port adhesive for crack injection process
• Non-sag patching material for cracks and small spalls
• Ideal for overhead and vertical repairs

Concrete:

• Prepare the concrete by abrasive blasting, high-pressure water cleaning, and/or approved mechanical method to achieve clean, sound, and profiled concrete.
• When logistics permit, prepare concrete in accordance with SSPC-SP 13/NACE No. 6. “Surface Preparation of Concrete.”

Steel:

• Before preparing steel, please inspect and remove oil, grease, or other contaminants - “Solvent Cleaning” (SSPC-SP1) may be required.
• Abrasive blasting (or other approved mechanical methods) must be used in order to achieve a clean surface with a minimum profile of 3 mils.
• To prevent flash rusting, consider the use of an Epoxytec recommended holding primer.

• Use CPP gel crack injection for small spall repairs only.
• A deeper or larger mass will generate excessive heat (with likely visible vapor), cracking and the material foaming / rising.
