Making an insulation using NEXLER Alu Aquastoper SP bituminous felt should be carried out according to the technical design, in accordance with the current building regulations and the detailed guidelines for the design and execution of insulation contained in NEXLER Insulation Systems and the Technical Data Sheet.
The bituminous felt should be installed in ambient temperatures of above 10°C in order to achieve proper adhesive properties. This requirement applies to the time of day and night.
Do not carry out insulation work during strong winds and precipitation.
In addition, the substrate should meet the following requirements:
- dry substrate (concrete in an air-dry condition, without any visible traces of moisture or darkening caused by moisture),
- clean substrate (the surface of the concrete is free of loose fractions, dust, oil stains, grease and other impurities),
- smooth substrate (local unevenness and cavities in the surface of concrete do not exceed ± 5 mm),
- even substrate (the gaps between the surface of the substrate and a 4 m long batten placed on the concrete substrate do not exceed 10 mm).
Before installing NEXLER Alu Aquastoper SP bituminous felt is recommended to prime concrete substrate with solvent-based bitumen primers for example NEXLER Penetrator G7, or water-based bitumen products for example NEXLER BITFLEX Primer.
NEXLER Alu Aquastoper SP bituminous felt should be fixed by bonding, using the self-adhesive properties, to a primed concrete substrate. Surfaces to which the felt will be bonded must be dry. Unroll and lay the roll in the area of the intended application, then remove the foil on the underside.
Press the bituminous felt onto the substrate, making sure it is pressed down over the entire surface, pay particular attention when working in the area of overlaps. Maintain overlaps min. 8 cm wide along the length of the felt strip and overlaps min. 12 cm wide at the joint perpendicular to the length of the felt strip.
Before use, please read the application details in the product's Technical Data Sheet.
