Kerdi Flex – Waterproof Joint O-Ring (walls, steps, joints, cracks)
\n<\/strong><\/h2>\n

Schl\u00fcter-KERDI-FLEX is a highly flexible waterproofing strip<\/strong> designed for sealing movement and perimeter joints in waterproofing systems<\/strong>. Its flexible polyethylene structure, coated on both sides with a special geotextile, allows its adaptation to areas with structural deformations and differential movements<\/strong>, ensuring a durable and resistant waterproof barrier<\/strong>.<\/p>\n

It is used in combination with Schl\u00fcter-KERDI, KERDI-KEBA and KERDI-COLL<\/strong>, ensuring continuous protection in critical areas such as swimming pools, bathrooms, terraces and industrial areas with high humidity.<\/p>\n

Main Uses<\/strong><\/h2>\n
    \n
  • Sealing of movement joints in walls and floors.<\/li>\n
  • Waterproofing of flexible perimeter o-rings.<\/li>\n
  • Protection against structural cracks in ceramic coverings.<\/li>\n
  • Use in swimming pools, spas, terraces and balconies exposed to thermal expansion.<\/li>\n
  • Application in industrial areas with constant humidity.<\/li>\n<\/ul>\n

    Technical Characteristics<\/strong><\/h2>\n
      \n
    • Material:<\/strong> Highly flexible polyethylene with geotextile on both sides.<\/li>\n
    • Thickness:<\/strong> 0.3 mm.<\/li>\n
    • Available widths:<\/strong> 12.5 cm and 25 cm.<\/li>\n
    • Roll length:<\/strong> 5 m and 30 m.<\/li>\n
    • High tensile strength and deformation resistance<\/strong>.<\/li>\n
    • Compatible with waterproof adhesives<\/strong> such as Schl\u00fcter-KERDI-COLL.<\/li>\n
    • ETA certification and CE marking<\/strong>, complying with DIN 18534 and DIN 18535 standards.<\/li>\n<\/ul>\n

      Advantages<\/strong><\/h2>\n

      \u2705 High elasticity for expansion joints.
      \n\u2705 Total waterproofing in critical areas.
      \n\u2705 Prevents cracks and leaks in moving structures.
      \n\u2705 Easy installation with KERDI-COLL adhesive.
      \n\u2705 Compatible with Schl\u00fcter-KERDI and Schl\u00fcter-DITRA systems.<\/p>\n

      Installation Mode<\/strong><\/h2>\n
        \n
      1. Prepare the surface<\/strong> making sure it is clean and free of dust.<\/li>\n
      2. Apply<\/strong> Schl\u00fcter-KERDI-COLL waterproof adhesive<\/strong> to the o-ring or overlap.<\/li>\n
      3. Place the KERDI-FLEX band<\/strong> ensuring a uniform distribution of the adhesive.<\/li>\n
      4. Press firmly to<\/strong> eliminate air bubbles and improve Floor anchor.<\/li>\n
      5. Wait for the<\/strong> tile to dry<\/strong> before tile installation.<\/li>\n<\/ol>\n

        Recommended Applications<\/strong><\/h2>\n

        \u2714 Pools and spas<\/strong>: waterproofing of structural joints.
        \n\u2714 Bathrooms and Shower<\/strong>: Sealing perimeter joints.
        \nIndustrial areas<\/strong>: Protection in areas with high humidity.
        \nTerraces and balconies<\/strong>: Prevention of cracks in o-rings subjected to thermal expansions.<\/p>\n
