Product Description:

Ardex TLT-718 Shower Waterproofing Membrane is a high-quality, environmentally friendly waterproofing and vapor-retarding membrane designed for reliable moisture protection in demanding interior wet areas. Manufactured by ARDEX, this premium waterproofing membrane is supplied in a 1 m (39.3 inch) wide roll and is engineered to deliver long-term durability, performance, and peace of mind in both residential and commercial applications.

The Ardex TLT-718 waterproofing membrane features a robust nonwoven polypropylene fabric laminated on both sides, creating an exceptionally strong bonding surface for polymer-modified thin-set mortars. This dual-sided fabric construction allows the membrane to mechanically bond to the substrate below while securely anchoring ceramic tile, porcelain tile, natural stone tile, and glass tile above. As a result, the membrane forms a continuous waterproof barrier that protects tile installations from water intrusion, moisture migration, and vapor transmission.

Designed for modern bathrooms, steam rooms, and high-humidity environments, Ardex TLT-718 provides a low permeability rating that makes it ideal for showers, steam showers, and other areas requiring vapor control. The membrane effectively prevents water vapor from penetrating wall and floor assemblies, helping to protect adjacent rooms, structural components, and finishes from moisture-related damage such as mold growth, tile failure, and substrate deterioration.

Ardex TLT-718 waterproofing membrane is suitable for a wide range of applications, including residential bathrooms, shower stalls, bathtub surrounds, kitchens, and laundry areas, as well as commercial environments such as hotels, restaurants, galleries, malls, food courts, and wellness facilities. It is also approved for demanding installations such as steam rooms and swimming pool environments where high levels of moisture and vapor pressure are present.

Once installed using an ARDEX high-performance polymer-modified thin-set mortar and allowed to fully cure, tile installation can proceed directly over the membrane. Ceramic tile, porcelain tile, travertine, limestone, marble, agglomerates, glass mosaic, and other stone tiles can be installed with confidence, knowing that the waterproofing layer beneath provides superior protection and long-term reliability. Ardex TLT-718 is equally well suited for new construction and renovation projects, including DIY applications and upgrades to older floors and walls, making it a versatile solution for comprehensive waterproofing and vapor control.
