Mapeguard UM 35 is the new decoupling waterproofing membrane. Suitable for use with cracked, damp and imperfectly cured substrates, when installing ceramic, porcelain and stone material to interior and external floors. It is used by laying the membrane between two applications of a Mapei adhesive, in order to accommodate any potential stresses and improve the bond strength of adhesive applied on both sides.
When used as part of a waterproofing system, Mapeguard UM 35 is completely watertight with the capability of protecting the substrates from water penetration, resulting in an increased durability.
Mapeguard UM 35 has also been specially designed to guarantee that the heat is distributed more evenly when applied on heated substrates.
Available in 30 x 1m rolls, the design structure of the membrane makes it easier to distribute the adhesive; the dimples on the surface of the membrane are filled which prevents air being trapped, and instead ensures complete coverage between the tile and membrane. Thanks to the air channels on the back of Mapeguard UM 35, any humidity present in the substrates can evaporate without affecting the tile finish.
Additionally, its semi-transparency backing makes application much easier for installers to check the coverage of adhesive when bonding the membrane. This additional benefit also helps to easily locate the presence of potential elements on substrates, such as drains, which makes any essential cuttings to the membrane straightforward.
The membrane allows the control of cracks in the substrate, while allowing the distribution of stresses on floorings subject to heavy loads. In accordance with TCNA test reports complying with ASTM C 627, therefore Mapeguard UM is certified as ‘Extra Heavy Commercial Rating’.
Mapeguard UM 35 ensures long-lasting protection from water infiltration and heavy loads. Mapei has you covered.
