Making an insulation using NEXLER STANDARD V60 S30 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 +5°C, 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 welding NEXLER STANDARD V60 S30 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 STANDARD V60 S30 bituminous felt should be fixed by welding to a primed concrete substrate.
Application should be carried out after the priming agent has completely dried (or cured).
As a result of heating both the substrate and the underside of the bituminous felt with a burner, the thin protective plastic foil melts, the asphalt is slightly melted and the bituminous felt sticks evenly to the substrate. Maintain a bituminous felt overlap min. 8 cm wide along the length of the felt strip and an overlap min. 12 cm wide at the joint perpendicular to the length of the felt strip. An asphalt outflow of approx. 0,5 cm in width over the entire length of the welded overlap is required.
Before use, please read the application details in the product's Technical Data Sheet.
