Waterproofing, uncoupling and anti-fracture membrane for cracked and damp substrates and substrates that are not fully cured before installing ceramic and stone tiles.

Where to Use

Installation on internal and external substrates as an uncoupling and anti-fracture membrane for laying ceramic and stone flooring on difficult, cracked substrates and on substrates that are not fully cured, and without having to copy the layout of control joints and expansion joints (as defined in UNI 11493-1 and UNI 11714-1) in the substrate.

• Mapeguard UM 35 is suitable for waterproofing balconies and terraces since it creates an uncoupling and vapour compensation layer on damp substrates and/or on substrates that are not fully cured.
• Mapeguard UM 35 is a waterproofing uncoupling and anti-fracture membrane that allows moisture in the underlying layers to be released.
• Mapeguard UM 35 is suitable for installing ceramic and stone tiles, including when overlaying existing flooring.
• Mapeguard UM 35 may be used in the following settings:
• New residential buildings and residential buildings being renovated
• Commercial Settings
• Hospitals
• Hotels
• Balconies and Terraces
• Bathrooms.

It is also suitable for these types of substrates:

• Concrete
• Cementitious Screed
• Cementitious Ccreeds with Heating Systems
• Anhydrite Screeds
• Anhydrite Screeds with Heating Systems
• Old Ceramic, Resin and Wood Flooring.

Technical Characteristics

Mapeguard UM 35 is a membrane made from a layer of honeycomb HDPE with a rough surface and polypropylene fabric backing. These characteristics improve the bond strength of adhesive applied on both sides of Mapeguard UM 35

Advantages

Crack control
Mapeguard UM 35 allows the control of cracks in the substrate, acting as an anti-fracture membrane and as an uncoupling element that prevents transmission of substrate cracks to the flooring.

Waterproofing Properties
Completely waterproof with the capacity to protect substrates from infiltrations of water and increase their durability. May be used on internal and external surfaces in combination with Mapeband Easy for sealing joints between the sheets and waterproofing critical areas (edges, corners, etc).

Vapour Control
Thanks to the air channels on the back of the membrane, the moisture in the underlying layers can evaporate; Mapeguard UM 35 is thus suitable for use on damp substrates and/or on substrates that are not fully cured, including in external surroundings.

Mechanical Strength
Mapeguard UM 35 allows the distribution of stresses also on floorings subject to heavy loads; it is certified as EXTRA HEAVY COMMERCIAL RATING according to TCNA test reports complying with ASTM C 627 and is suitable for use in residential and commercial surroundings.

Even Heat Distribution
Mapeguard UM 35 guarantees that heat is distributed more evenly when applied on heated floors, including compact heated floors.

Transparency
Mapeguard UM 35 is semi-transparent, and this allows to verify the correct distribution of the adhesive underneath, as well as to easily locate the presence of potential elements passing through surfaces (such as drains), thus making the cutting of the membrane easier.

Improved Adhesion
The special shape of the embosses offers a perfect mechanical bonding of the adhesive to obtain a high adhesion between the ceramic or stone covering and Mapeguard UM 35.

Recommendations

• The substrate must have an adequate mechanical strength according to expected loads.
• Do not use in correspondence with structural joints in the substrate.
• Do not apply over cracks or joints subject to out-of-plane movement.
• Do not apply directly over structural cracks and/or cracks wider than 3 mm.
• Do not use tiles smaller than 5x5 cm.
• For substrates with residual moisture, use Mapeband Easy to seal joints between adjacent sheets of membrane.
• Do not use on dry anhydrite substrates unless they have been treated beforehand with special primer such as Primer G or Eco Prim T Plus.
• Anhydrite-based substrates must have a maximum residual humidity of 2%.
• Do not apply directly on bitumen membranes.
• Mapeguard UM 35 needs to be covered with stone or ceramic flooring material.
• Do not use on lightweight screeds.
