This red 5 inch x 82 foot joint strip helps connect membrane sheets, shower wall panels, shower floor areas, shower curbs, bathtub waterproofing zones, shower niches, shower bases, shower trays, and wet room surfaces into a continuous waterproofing layer. With a 0.35 mm thick membrane construction, it supports dependable shower waterproofing, bathroom shower waterproofing, and waterproof membrane for tile installations in both residential and commercial projects.\u003c\/p\u003e\n\u003cp\u003eDesigned for use with premium polymer-modified thinset mortar, PROVA JOINT bonds into compatible waterproofing membrane assemblies to help seal floor-to-wall transitions, vertical seams, horizontal seams, inside corners, and surface changes. The 5 inch width supports the required 2 inch overlap at seams and transitions in the PROVA waterproofing system, helping reduce the risk of water penetration behind tile. The roll can be cut to the exact length needed, pressed into fresh thinset, and embedded smoothly before installing ceramic tile, porcelain tile, marble tile, granite tile, mosaic tile, glass tile, stone tile, cement tile, or other suitable floor tiles and wall tile finishes.\u003c\/p\u003e\n\u003cp\u003eThis waterproofing joint strip is especially useful in shower systems, shower wall kit installations, shower waterproof projects, steam shower kit builds, bathtub surround renovations, wet room upgrades, laundry rooms, bathroom tile projects, kitchen waterproofing areas, and other home improvement work where water exposure must be controlled. It helps reinforce seams near shower pans, tile ready shower bases, shower floor tile, shower floor base connections, linear shower drain areas, shower flange transitions, drain pan edges, floor drain cover zones, and shower curb details when used as part of a complete tile waterproofing system.\u003c\/p\u003e\n\u003cp\u003eThe flexible polypropylene design conforms to joint lines and changes in plane, making it easier to install than trying to fold larger waterproofing membrane sheets into corners. Its roll format reduces interruptions on larger jobs, helps limit waste, and provides efficient coverage for long seams in bathrooms, foyers, closed balconies, hallways, commercial washrooms, and other interior wet areas. Since PROVA JOINT resists mold and mildew growth and is approved for residential steam showers, it is a strong choice for vapor-sensitive spaces that need reliable waterproof shower base liner performance and long-lasting moisture protection.\u003c\/p\u003e\n\u003cp\u003eUse this waterproofing membrane strip as part of a complete PROVA shower system or compatible tile membrane underlayment assembly to support durable protection beneath tile adhesive, thinset mortar, and finished tile surfaces. For best results, install over properly prepared substrates, maintain the specified overlap, avoid premixed mortar or mastic where not recommended, and follow all system instructions for seams, corners, transitions, and penetrations. Whether used by professional tile contractors or for carefully planned DIY projects, this PROVA JOINT roll helps create a clean, efficient, and dependable waterproofing solution for modern shower, bathroom, and wet area installations.\u003c\/p\u003e","brand":"Prova","offers":[{"title":"Default Title","offer_id":48833294631129,"sku":"Prova_Band","price":65.5,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/4676\/8089\/files\/ListingPics_1_54eecaf4-438c-4a54-ad93-84286e68b809.png?v=1781875105","url":"https:\/\/gtdsupply.com\/products\/prova-tt8001red82r-waterproofing-polypropylene-membrane-25m-band-roll-5-x-82-joint-strip","provider":"Global Trade \u0026 Distribution Inc.","version":"1.0","type":"link"}
