Designed to perform in applications where water is seeping or mildly leaking from the crack, the polyurethane is packaged in the cartridge and an accelerator is packaged in the nozzle. 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCan be dispensed with a standard caulking tool\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCan also be used on dry cracks if water is introduced to affected area\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCan be used with a reduced amount or without accelerator to slow down reaction time\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eExpands to fill voids and seal the affected area\u003c\/li\u003e\n\u003cli\u003eFast 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)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e20:1 expansion ratio (unrestricted rise) means less material needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eColor -\u003c\/strong\u003e \u003cbr\u003ePolyurethane - Clear\u003cbr\u003eAccelerator - Green\u003cbr\u003eCured Color -\u003cstrong\u003e Green\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStorage Conditions -\u003c\/strong\u003e for best results, store in a dry area between 45°F (7°C) and 90°F (32°C).\u003cbr\u003eProduct is very moisture sensitive\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUsage Temperatures:\u003c\/strong\u003e 60\u003cspan\u003e°F - 90°F\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eShelf Life: \u003c\/strong\u003e12 months from the date of manufacture, unopened\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eInstallation\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eSuitable for sealing cracks ranging from 1\/32\" to 1\/4\" wide in concrete and solid masonry.\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSuitable for repair of cracks in dry, damp and wet conditions with excellent results.
