• Features & Benefits
• Application Notes

Features & Benefits

• Low viscosity - penetrates fine cracks and cavities
• Reacts with water and forms flexible closed cells that allow the movement of the crack
• Flexible to withstand differential movement
• Free expansion: 800%
• Chemically resistant against water, weak acids, alkali and micro-organisms
• Excellent adhesion to mineral construction materials (such as concrete, cement, brick and mortar) and metal

Application Notes

• Ensure all contact surfaces are free from oil or grease contamination and suitably prepared to allow Nitokit Surface Sealant to bond
• Injection packers should be inserted into holes drilled at a 45 degree angle to the surface such that they intersect the crack. The distance between each packer is typically between 200 mm and 500 mm depending on the width of crack, depth of crack and degree of water penetration / water pressure
• Before commencing ensure the first packer to be injected has its non-return valve fitted. All other packers should be open
• Pre-weigh required quantities of the resin and hardener. Mix together thoroughly using a drill and paddle, mixing only the amount which can be used within the pot life (see Product Data Sheet)
• Pour the mixed material into the hopper of the injection equipment being used. Connect the outlet hose to the first injection packer and activate the pump
• When resin or foam is seen coming from the next injection packer, deactivate the pump immediately and install a nonreturn valve onto the next packer. Move the injection hose to the next packer and repeat until the entire crack is sealed
• Tools and application equipment should be cleaned immediately after use using a proprietary polyurethane cleaner. Once cured, material can only be removed mechanically. Spillages should be absorbed with sand or sawdust and disposed of in accordance with local regulations
• Clean pump and manual equipment every time there is a stop of more than 15 minutes with a proprietary cleaner, or whenever necessary and at the end of the injection. Flush with an extra 1/4 litre of cleaner

Note: Nitofill UR63 is only to be used in wet or damp concrete or masonry where flexibility is required.
