Mapei Mapeheat Maxi Lightweight Uncoupling Anti-Fracture Waterproofing Membrane 15m

Mapeheat Membrane Maxi is a lightweight uncoupling, anti-fracture and waterproofing membrane for electrical underfloor heating. This patented membrane is designed to speed up the installation of tile and stone in interior rooms such as bathrooms, kitchens and living areas where the luxury of radiant floor heating is desired. Mapeheat Membrane Maxi's thin profile works well with remodelling projects where the new floor will be installed directly over a pre-existing one. Once the heating cable is set within Mapeheat Membrane Maxi's reliefs, a tile adhesive or levelling/smoothing compound can be applied immediately.

Advantages:
- Suitable for multiple-size cables: diameters from 2 to 5.5mm.
- Thin profile.
- Helps prevent transmission of in-plane substrate cracks (cracks width: up to 3 mm).
- Minimal roll memory for faster installation.
- Heating cable installs easily, and lays flat and secure.
- For the installation of ceramic tiles the use of minimum class C2 adhesives (in compliance with EN 12004) is recommended (to be chosen dependently from the tile size).

Where To Use:
- Use under ceramic, porcelain and natural stone tiles in interior residential spaces such as kitchens, bathrooms, shower oors and living areas.
- Use as a substrate to receive smoothing compound prior to installing engineered wood, luxury vinyl tiles, luxury vinyl planks, laminate flooring and mosaic tile.

Some Application Examples:
For the installation of Mapeheat Cable heating over:
- Concrete cured for a minimum of 6 weeks.
- Sand: cement screeds cured for a minimum of 7 days and capable of supporting tile installation traffic without leaving any indentations.
- Tile adhesives and smoothing compounds.
- Tile backer boards – see manufacturer’s installation guidelines.
- Exterior grade plywood at a minimum thickness as outlined in the local standards.
- Existing, well-bonded ceramic tile and dimensionally stable natural stone.
- Existing, firmly bonded luxury vinyl tiles.
