{"product_id":"prova-flex-underlayment-roll","title":"PROVA-FLEX® Underlayment Roll","description":"\u003cp\u003ePROVA-FLEX® is a durable, lightweight uncoupling membrane that provides crack isolation protection to concrete or wood substrates. The underlayment consists of three layers: a top layer of woven polypropylene mesh, a central sheet of polypropylene, and a bottom layer of non-woven polypropylene. The top layer provides a mechanical bond between the cured thin set and tiles, and allows for the efficient spread of thin set mortar; the central layer includes hollow studs for holding modified thin set mortar; and the bottom layer, which is secured with a polyolefin-based adhesive, provides Shear Stress Control by neutralizing stress caused by substrate movement. This underlayment is lightweight and is an easy-to-install alternative to backer board.\u003c\/p\u003e","brand":"M-D Building Products","offers":[{"title":"269 sq. ft.","offer_id":54869920416083,"sku":"TT8004RED82R","price":172.0,"currency_code":"GBP","in_stock":true},{"title":"54 sq. ft.","offer_id":54869920448851,"sku":"80212","price":42.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1076\/9324\/4755\/files\/80212_TT8004RED16R_TT8004RED82R_Profile_2_0de85d14-fe56-49a6-9bcb-26f5f732a56a.jpg?v=1788837409","url":"https:\/\/progradewarehouse.com\/products\/prova-flex-underlayment-roll","provider":"PRO GRADE WAREHOUSE","version":"1.0","type":"link"}
