General characteristics

– Once applied, UltraFlex PW forms a durable, elastic and watertight membrane with high wear resistance and great stability. No joints or overlaps providing a uniform and continuous finish that facilitates optimal cleaning and maintenance.

– Application in layers of approximately 0.8 to 1 mm, to achieve a total thickness of 2mm (consumption between 2 and 2.5 Kg / m2). Due to its thixotropy characteristics, it is suitable and easy to apply on vertical surfaces.

– It can be assembled in singular points and encounters with other construction elements.

– Keep the membrane protected from sunlight.

– Avoid its application on substrates with the presence of humidity due to negative pressure, either at the time of application or later. If that’s the case, apply a barrier system first.
