Product Description:

With high tear-resistance, Subliner Dry withstands mechanical stress and harsh conditions, remaining resilient over time without decomposing. This in-floor underlayment membrane is specially formulated to help prevent cracks in shower floor tile and grout by helping bridge minor substrate movement beneath tile and stone finishes. Crafted from tear-resistant polyethylene film and featuring dual-sided special fleece lamination, it ensures optimal anchoring for tile-laying materials and strong adhesion with suitable tile-setting compounds.

Its attributes include 100% waterproofing capability, effectively guarding against water infiltration, while also serving as a water vapor retardant for wet rooms, showers, steam showers, and high-humidity tile assemblies when installed as part of the complete wedi Subliner Dry System. It makes installation a breeze, saving you time and effort, with a pliable sheet design that can be cut with a knife or scissors and printed surface markings that support measuring, layout, and cleaner installation. This membrane forms a strong bond thanks to its dual-sided special fleece lamination, which helps tile-setting materials grip both the substrate side and tile side. No fasteners are required for the installation, simplifying the process and saving time because the membrane is embedded into thin-set mortar, while overlapped seams, joints, and transitions are sealed with wedi Sealant 620 to help create a waterproof and vapor-proof connection within the Subliner Dry System.

Wedi Subliner Dry Mat isolation membrane functions as both a waterproof and vapor-proof sheet membrane underlayment for tile, while also providing crack isolation benefits for moisture-prone flooring applications that require an uncoupling membrane for tile. This makes it suitable for crack prevention in various floor tiles, such as ceramic tile, porcelain tile, granite tile, marble tile, glass tile, mosaic tile, and natural stone tile. It can also be used with ceramic slabs and natural stone cladding for indoor wall and floor areas, making it a practical waterproofing membrane for bathrooms, wet rooms, showers, kitchens, laundry rooms, and other moisture-prone tile installations. In case of minor substrate movement, it effectively absorbs stress, preserving the surface and integrity of the ceramic floor tile. It is easy to install and compatible with various tile types, offering superior protection and stability for your waterproof flooring projects.

Whether used in standard applications or over challenging substrates, the in-floor isolation membrane ensures the longevity and performance of your tile installations by helping create a continuous waterproofing layer over suitable pre-existing wall or floor underlayment and approved non-waterproof substrates. This membrane underlayment can also be used when renovating older kitchen tile flooring, basement flooring, and bathroom floor tile. Because it belongs to a coordinated wedi waterproofing system, it helps reduce product-to-product compatibility guesswork when used with wedi sealing tape, corners, collars, drains, and sealant details. It comes in a convenient roll format, making it suitable for professional home improvement or DIY projects of all scopes. It is a great option for supporting long-lasting room decor, bathroom decor, kitchen decor, and home decor needs where a durable, tile-ready waterproof flooring underlayment is required beneath the finished surface.
