Squeeze it straight onto the leak above or below the waterline, smooth it with a wet finger, and it skins over in seconds and cures to a tough, flexible patch. The blue color is tuned to blend with most vinyl liners, so small liner repairs disappear instead of standing out. Use it with or without a vinyl patch, as a thread sealant on small suction-side plumbing, or to seal hairline cracks in plaster and gunite.\u003c\/p\u003e\n\n  \u003csection class=\"andfs4b-spec-section\"\u003e\n    \u003cdiv class=\"andfs4b-spec-heading\"\u003eSpecifications\u003c\/div\u003e\n    \u003ctable class=\"andfs4b-spec-table\"\u003e\n      \u003ctbody\u003e\n        \u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eAnderson Manufacturing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eModel \/ MPN\u003c\/th\u003e\n\u003ctd\u003eFS4B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePST SKU\u003c\/th\u003e\n\u003ctd\u003ePST-ANDFS4B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUPC\u003c\/th\u003e\n\u003ctd\u003e713965404027\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eFlexible pool repair sealer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColor\u003c\/th\u003e\n\u003ctd\u003eBlue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e4 oz tube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eChemistry\u003c\/th\u003e\n\u003ctd\u003eNitrile rubber based\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCure\u003c\/th\u003e\n\u003ctd\u003eSkins in seconds, fully cures in minutes to hours by thickness\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUse Location\u003c\/th\u003e\n\u003ctd\u003eAbove or below water\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBonds To\u003c\/th\u003e\n\u003ctd\u003eVinyl, PVC, fiberglass, ceramic, plaster, gunite, metal fittings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCommon Uses\u003c\/th\u003e\n\u003ctd\u003eVinyl liner leaks, faceplate and fitting seals, thread sealant, small plumbing leaks, plaster cracks\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003c\/tbody\u003e\n    \u003c\/table\u003e\n  \u003c\/section\u003e\n\n  \n  \u003csection class=\"andfs4b-faq\"\u003e\n    \u003cdiv class=\"andfs4b-spec-heading\"\u003eGood to Know\u003c\/div\u003e\n    \n    \u003cdiv class=\"andfs4b-faq-item\"\u003e\n      \u003cp class=\"andfs4b-faq-q\"\u003eCan I apply FS4B underwater?\u003c\/p\u003e\n      \u003cp class=\"andfs4b-faq-a\"\u003eYes.
