Mapeguard UM 35 – Waterproofing, Uncoupling & Anti-Fracture Membrane

Description:
Mapeguard UM 35 is a high-performance waterproofing, uncoupling, and anti-fracture membrane designed for the installation of ceramic and stone tiles on internal and external surfaces. It is ideal for use on cracked or damp substrates, as well as substrates that are not fully cured. It eliminates the need to replicate distribution, control, or expansion joints from the substrate into the tile layer.

Applications:
Mapeguard UM 35 can be installed over difficult substrates as an uncoupling and anti-fracture layer, providing a reliable base for ceramic and stone flooring. It is suitable for both new construction and renovation projects, even when tiling over existing floors.

Where to Use:
Mapeguard UM 35 is ideal for:

Waterproofing balconies and terraces by forming an uncoupling and vapour-compensating layer on damp or uncured substrates
Moisture management, allowing vapour from underlying layers to escape
Overlaying existing ceramic, resin, or wood flooring
Installing tiles in both residential and commercial environments

Recommended Settings:

New and renovated residential buildings
Commercial properties
Hospitals
Hotels
Balconies and terraces
Bathrooms

Compatible Substrates:

Concrete
Cementitious screeds (with or without underfloor heating)
Anhydrite screeds (with or without underfloor heating)
Existing ceramic, resin, or wood floorings

Technical Characteristics:
Mapeguard UM 35 consists of a high-density polyethylene (HDPE) sheet with a structured honeycomb surface and a polypropylene non-woven fabric backing. This construction enhances adhesive bonding on both sides of the membrane, ensuring a strong and reliable tile installation.

Packaging:
Available in 30 m x 1 m rolls.
