Built with a high-density polyethylene core and a thickness of 23.6 mils, this underlayment is designed to help manage moisture in wet spaces such as bathrooms, kitchens, saunas, and other damp areas. It functions as an uncoupling membrane, helping to protect joints and connections between floors and walls while supporting tile adhesion over time.\u003c\/p\u003e\n\u003cp\u003eThe membrane combines a sturdy core with a protective non woven fabric layer. This construction resists detachment and fiber pilling during mortar application, so you can lay tiles with greater confidence. When used as part of a shower or bathroom remodel, it acts as a barrier against moisture movement that can affect underlying materials, contributing to a drier, more stable substrate behind the finish.\u003c\/p\u003e\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eTop-grade waterproofing: 23.6 mil thickness provides robust moisture resistance for wet areas.\u003c\/li\u003e\n  \u003cli\u003eUncoupling membrane design: seals floor to wall joints and butt joints to help prevent movement from affecting tile adhesion.\u003c\/li\u003e\n  \u003cli\u003eDurable and reliable: high-density core paired with a non woven fabric layer minimizes detachment and pilling during mortar work.\u003c\/li\u003e\n  \u003cli\u003eFlexible and cuttable: easily trimmed with scissors or a knife to fit irregular spaces, reducing waste.\u003c\/li\u003e\n  \u003cli\u003eTwo-layer application: simple workflow that starts with a base layer, followed by full coverage with the membrane, then the final waterproof layer.\u003c\/li\u003e\n  \u003cli\u003eWide applicability: suited for bathrooms, kitchens, saunas, laundry rooms, and other wet areas; compatible with tile, marble, cement boards, and stone tiles.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePractical use and installation tips\u003c\/h3\u003e\n\u003cp\u003eImagine a bathroom remodel where a dry surface remains even after steamy showers. This membrane aims to help create that scenario by protecting interior wood and insulation from moisture intrusion and leakage. Because it can be cut to size and folded to fit the laying area, you can shape it to corners, niches, and around fixtures without creating excessive waste.\u003c\/p\u003e\n\u003cp\u003eTo install, cut the membrane to size, spread a base layer to hold it in place, place the cut piece over the work, then apply the final layer of waterproofing. The result is a more uniform feel under the tile and less worry about movement at joints. For best results, ensure compatibility with your chosen adhesives and grouts and follow standard tile setting practices.\u003c\/p\u003e\n\u003cp\u003eWhether you are refreshing a shower stall or remodeling a kitchen splash, this membrane offers a practical option that emphasizes ease of use and consistent moisture protection in busy, damp environments.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What surfaces is the membrane suitable for?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Suitable for bathroom showers, kitchens, saunas, laundry rooms, and other wet areas.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How easy is it to install and cut to fit?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It can be cut with scissors or a knife and applied in two layers for full coverage.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"JIANBENKJ","offers":[{"title":"Default Title","offer_id":47468084494510,"sku":"B0FD71D4BK","price":113.91,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/6012\/9710\/files\/jianbenkj-waterproof-membrane-shower-roll-33ft.jpg?v=1770392136","url":"https:\/\/handyskook.ca\/products\/jianbenkj-waterproof-shower-membrane-3-3ft-x-33ft-108-sq-ft-uncoupling-tile-underlayment","provider":"HandySkook","version":"1.0","type":"link"}
