Simpson CIP-F Flexible Crack Injection Paste-Over Adhesive and Crack Sealant by Simpson is a flexible, peelable, and fast-curing polyurea paste-over material engineered to temporarily seal concrete cracks and hold injection ports firmly in place before epoxy or urethane foam injection repair. Its zero-VOC, non-sag paste formula performs reliably on horizontal, vertical, and overhead surfaces, and its moderate bond strength is designed specifically to allow clean, complete removal once the injection repair is finished. Each unit comes ready to use as a 22 oz. side-by-side cartridge and includes a mixing nozzle.

Key Features

• 1:1 two component, high solids, epoxy amine based adhesive - delivers a consistent, predictable mix every time, reducing waste and guesswork during crack injection prep.
• Non-sag paste consistency - stays exactly where you apply it on horizontal, vertical, or overhead concrete surfaces, giving you control in any work orientation.
• Fast cure times - shortens the wait between paste-over application and the start of injection, helping crews move through jobs more efficiently.
• Remains flexible after cure - the cured material flexes rather than becoming brittle, making it significantly easier to peel away cleanly at job completion.
• Moderate substrate bond that peels away for removal - bonds securely enough to seal and hold ports during injection, yet releases cleanly by hand when the job is done, with no chipping or grinding required.
• 0 g/L VOC content - meets strict low-emission requirements, making it suitable for use in confined or poorly ventilated spaces without adding chemical exposure concerns.

Why This Product

• Designed specifically for the crack injection workflow - unlike general-purpose adhesives, this paste-over is formulated to complement epoxy and urethane foam injection repair, sealing cracks and anchoring ports precisely where they need to be, then releasing cleanly once the repair is complete.
• Works in real-world conditions, including cold weather - with a defined gel time of 9 minutes at 40 deg. Fahrenheit (4 deg. Celsius) and a cure time of 3 hours at 40 deg. Fahrenheit (4 deg. Celsius), contractors can continue working in cooler temperatures without losing material performance.
• No mess, no grinding after removal - the flexible, peelable formulation lets workers pull the paste-over off using starter tabs or by prying under the edge, leaving the surface ready without the extra labor of mechanical removal.
• Zero VOC formula made in the United States - the 0 g/L VOC rating keeps the product in compliance with stringent air quality standards, while the domestic origin reflects consistent quality control from production through packaging.

Frequently Asked Questions

What is the CIP-F22 used for?

The CIP-F22 is used to temporarily seal cracks and to secure injection ports over concrete prior to epoxy or urethane foam injection repair. Once the crack injection job is complete, the paste-over material can be removed from the surface.

How is the CIP-F22 paste-over removed after a crack injection job?

CIP-F can be peeled off at the completion of a crack injection job by pulling on starter tabs placed under the lead edge surface at the time of application, or by prying under the paste-over. The material remains flexible after cure, which makes removal easier.

How long does the CIP-F22 take to cure?

At 72 deg.F (22 deg.C), the gel time is 4 minutes and the full cure time is 1 hour. At colder temperatures of 40 deg.F (4 deg.C), the gel time extends to 9 minutes and the cure time extends to 3 hours.

Can the CIP-F22 be applied to vertical or overhead surfaces?

Yes. The CIP-F22 features a non-sag paste consistency that makes it suitable for horizontal, vertical, and overhead applications without slumping or running before it cures.
