SELF-ADHESIVE BREATHABLE MONOLITHIC MEMBRANE
DEFENCE ADHESIVE TRASPIR EVO
The homogeneous and continuous monolithic functional layer provides maximum protection against the passage of water and high breathability.
The special compound ensures significant weather resistance and excellent durability over time.
Thanks to the patented glue, the membrane remains perfectly breathable even when fully bonded, allowing any wet elements to dry out.
Easy to install thanks to the semi-transparent structure that allows the underlying structure to be visible.

Description
The membrane can be used for temporary protection, rather than as a long-term functional layer, of construction elements (walls and floors) for a maximum duration of 14 weeks.
The application surface must be dry, free of dust and grease, and not be anti-adhesive. Surface elements must be removed so that the membrane is not damaged during application.
Once applied, the product allows for easy visibility of powder tracer markings and underlying mounting holes.
Installation:
Unroll the membrane over the surface to be protected, progressively remove the release film from the adhesive, and press the membrane firmly to ensure proper adhesion. In case of a mistake during installation, the membrane can be repositioned and reapplied without difficulty during the first few minutes.
Ensure that the overlap between the membranes is at least 15 cm to achieve an optimal seal.
If installed on walls, the membrane must be laid horizontally, starting from the base of the wall and progressing upwards to the top.
Further details regarding installation can be found in the specific instructions provided by the supplier.
