The uncoupling mat allows the ceramic or stone cladding to be completely separated from the existing substrate while maintaining its continuity and uniformity regardless of the size of the tiles being installed. It allows the expansion joints in the cladding to be moved beyond the existing substrate expansion system. The use of ATLAS T 100 UNCOUPLING MAT to separate the expansion joints of the ceramic cladding from the expansion joints in the existing substrate is shown in Technical Data Sheet.
The uncoupling mat allows the installation of continuous, homogeneous ceramic cladding of various formats, including large-format, on various types of difficult substrates without the need for removal in the following cases:
- rooms with different types of flooring, e.g. parquet and ceramic tiles,
- substrates with underfloor heating occurring in part of the room,
- contaminated substrates with reduced adhesion, e.g. adhesive and bitumen residues from parquet stripping, PVC flooring adhesives, linoleum adhesives, carpet adhesives, glued laminate adhesives, etc.
- weakened substrates with a layer of cement scale on the surface,
- substrates with shrinkage cracks (no vertical displacement),
- substrates in rooms with a complex geometry and expansion joints,
- substrates with shaped threshold expansion joints in transitions between rooms,
- installation of ceramic cladding on insufficiently seasoned substrates, with increased bulk moisture (< 6 %)
An example of the application of Atlas T 100 is shown in Figures 3 and 4.
For interior use, in residential, office and service areas with an assumed imposed load of up to 3.0 KN/m²
Most important features
- allows ceramic cladding to be laid without the need for mapping of substrate expansion joints
- allows for an independent expansion joint system
- allows large-format tiles to be installed without moving the threshold expansion joints
- for laying ceramic tiles on contaminated substrates with reduced adhesion
- significantly speeds up the installation of new ceramic coverings in a single room when the substrate is made up of different types of flooring
- makes it possible to create a uniform ceramic floor on adjacent subfloors with strongly varying thermal loads (e.g. with and without underfloor heating, highly sunny floor sections)
