Mapei's long-standing recommendation for outdoor carpet over concrete, wood, or fiberglass — pool decks, patios, walkways, and other exposed installs included.\u003c\/p\u003e\n\u003cp\u003eFreeze\/thaw stable, so performance holds up through temperature swings. Its unique formulation means it can be installed without moisture testing first — one less step before the job starts. Also suitable for bonding reground rubber underlayments like Mapesonic RM ahead of ceramic tile installs.\u003c\/p\u003e\n\u003cp\u003eEasy to trowel with plenty of open working time, even in warm conditions. Nonflammable, low-odor, and CRI Green Label Plus certified. Includes BioBlock technology, tested to ASTM G21 standards, so it doesn't support mold, mildew, or fungal growth after install (regular cleaning and maintenance still required).\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1996\/7489\/files\/ultrabond-eco-420.pdf?v=1786045297\" rel=\"noopener\" target=\"_blank\"\u003eClick here for Technical Data Sheet\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable style=\"width: 100%;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"width: 26.2938%;\"\u003eSpec\u003c\/th\u003e\n\u003cth style=\"width: 73.3452%;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 26.2938%;\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"width: 73.3452%;\"\u003eWater-based, moisture-resistant carpet adhesive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 26.2938%;\"\u003eUse\u003c\/td\u003e\n\u003ctd style=\"width: 73.3452%;\"\u003eIndoor\/outdoor broadloom carpet; reground rubber underlayment (e.g., Mapesonic RM)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 26.2938%;\"\u003eSubstrates\u003c\/td\u003e\n\u003ctd style=\"width: 73.3452%;\"\u003eConcrete, wood, fiberglass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 26.2938%;\"\u003eTechnology\u003c\/td\u003e\n\u003ctd style=\"width: 73.3452%;\"\u003eBioBlock (ASTM G21 tested — resists mold\/mildew\/fungi)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 26.2938%;\"\u003eMoisture testing\u003c\/td\u003e\n\u003ctd style=\"width: 73.3452%;\"\u003eNot required before install\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 26.2938%;\"\u003eHumidity tolerance\u003c\/td\u003e\n\u003ctd style=\"width: 73.3452%;\"\u003eUp to 80% relative humidity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 26.2938%;\"\u003eFreeze\/thaw stability\u003c\/td\u003e\n\u003ctd style=\"width: 73.3452%;\"\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 26.2938%;\"\u003eCertification\u003c\/td\u003e\n\u003ctd style=\"width: 73.3452%;\"\u003eCRI Green Label Plus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 26.2938%;\"\u003eFlammability\u003c\/td\u003e\n\u003ctd style=\"width: 73.3452%;\"\u003eNonflammable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 26.2938%;\"\u003ePackage sizes\u003c\/td\u003e\n\u003ctd style=\"width: 73.3452%;\"\u003e1 quart, 1 gallon, 4 gallon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need to test for moisture before installing?\u003c\/strong\u003e No — the unique formulation lets you skip moisture testing before install.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this go on outdoor concrete exposed to weather?\u003c\/strong\u003e Yes — it's freeze\/thaw stable and holds up to moisture, making it Mapei's top pick for outdoor carpet over concrete, wood, or fiberglass.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use it for tile underlayment instead of carpet?\u003c\/strong\u003e Yes — it also bonds reground rubber underlayments like Mapesonic RM ahead of ceramic tile installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it resist mold and mildew?\u003c\/strong\u003e Yes — BioBlock technology is tested to ASTM G21 standards for that.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cspan class=\"product-sku-search\" id=\"product-sku-search\"\u003eSku: \u003cspan\u003e94291000\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c!-- END FLOORCOMMANDER SKU INSERT --\u003e","brand":"Mapei","offers":[{"title":"1 quart","offer_id":48554255352002,"sku":"94291000","price":9.89,"currency_code":"USD","in_stock":true},{"title":"1 gallon","offer_id":48554255384770,"sku":"1042002","price":27.79,"currency_code":"USD","in_stock":true},{"title":"4 gallon","offer_id":48554255417538,"sku":"94264","price":100.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1996\/7489\/files\/mapei_eco420-1quart.jpg?v=1786045250","url":"https:\/\/flooringmarket.com\/products\/mapei-ultrabond-eco-420-adhesive","provider":"Flooring Market","version":"1.0","type":"link"}
