{"title":"Geocel","description":"\u003cdiv class=\"collection-intro\"\u003e\n\u003cp\u003eGeocel (Geocel Products Group, a business unit of The Sherwin-Williams Company) makes specialty sealants for roofing and building repair. This brand collection covers Geocel products currently in the Project Weekend DIY store, starting with Geocel 4500 Roof Bonding Sealant.\u003c\/p\u003e\n\u003cp\u003ePer GeocelUSA product literature, Geocel 4500 is a premium one-component Scypolymer bonding sealant designed for roofing applications. Maker materials say it can apply, adhere, and cure underwater, works as both a lap adhesive and scrim edge sealant, remains flexible, and uses a non-flammable formulation. Typical uses listed include repairing and sealing around through-roof projections, termination points, and flashings, plus EPDM lap cement and night-seal work. Substrates called out include asphalt shingles, steel, concrete, EPDM, primed TPO, primed PVC, Hypalon (black only), metal, wood, and other common building substrates. TPO and PVC membranes need primer (Geocel recommends 45P TPO \u0026amp; PVC Primer). Do not use on unprimed TPO or PVC, black sealant on white EPDM, white sealant on black EPDM, potable water applications, or areas where food is processed or stored. Our live SKU is black, 10 oz cartridge, manufacturer part GC55103.\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eLine\u003c\/th\u003e\n\u003cth\u003eBest for\u003c\/th\u003e\n\u003cth\u003eWhat we carry\u003c\/th\u003e\n\u003cth\u003eNotes (maker)\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e4500 Roof Bonding Sealant\u003c\/td\u003e\n\u003ctd\u003eRoof flashings, projections, EPDM lap\/scrim edge, asphalt shingles, metal, concrete, wood\u003c\/td\u003e\n\u003ctd\u003eBlack, 10 oz (GC55103)\u003c\/td\u003e\n\u003ctd\u003eOne-component Scypolymer; apply\/cure underwater; prime TPO\/PVC; remains flexible\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eShop related: \u003ca href=\"\/collections\/gaco\"\u003eGaco roof and deck coatings\u003c\/a\u003e, \u003ca href=\"\/collections\/prep-patch-specialty-coatings\"\u003eprep, patch, and specialty coatings\u003c\/a\u003e, and the \u003ca href=\"\/pages\/garage-floor-epoxy-project-cart\"\u003egarage floor cart\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat is Geocel 4500?\u003c\/summary\u003e\u003cp\u003eGeocel describes 4500 as a one-component Scypolymer roof bonding sealant that can work as a lap adhesive and scrim edge sealant on common roofing substrates.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhich surfaces does the maker list?\u003c\/summary\u003e\u003cp\u003eAsphalt shingles, steel, concrete, EPDM, primed TPO, primed PVC, Hypalon (black only), metal, wood, and other common building substrates.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDo TPO and PVC need primer?\u003c\/summary\u003e\u003cp\u003eYes.
