Making an insulation using NEXLER Stick 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, 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 Stick, it is recommended to prime the concrete substrate or the old bitumen coating with solvent-based asphalt agents, e.g. NEXLER Penetrator G7, or a water-based asphalt preparation, e.g. NEXLER BITFLEX Primer.
NEXLER Stick bituminous felt should be fixed using self-adhesive properties to EPS panels or other thermal insulation, to a primed concrete or sheet metal substrate. The bituminous felt can additionally be fixed mechanically. Application on concrete substrate should be carried out after the priming agent has completely dried (or cured). The final adhesion forces to the substrate in these cases are obtained after welding the next layer of bituminous felt onto the NEXLER Stick bituminous felt.
Surfaces to which the felt will be bonded must be dry. Once the roll has been unrolled, place it carefully in the space provided for it and cut off an appropriate section of the felt if necessary. Then remove the foil protecting the underside by pulling it simultaneously from both sides of the strip and at the same time pressing and levelling the surface of the felt after removing the foil.
NEXLER Stick bituminous felt can also be mechanically fixed together with or without thermal insulation to concrete, wood or sheet metal substrates. In that case the bituminous felt is fixed with mechanical connectors at the edge of the strip and then thermally activated at the overlaps. 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. The adhesive strength of the self-adhesive surface is optimal at ambient temperatures above 10°C. The best self-adhesive effect is achieved when welding the next layer of felt.
When carrying out vertical and horizontal detail work, the undersurface of the felt should be additionally heated to increase the adhesive strength. In areas that were folded vertically - cover with top-layer weldable bituminous felt in one working cycle. Details of substrate preparation and bituminous felt fixing are described in NEXLER Insulation Systems.
Before use, please read the application details in the product's Technical Data Sheet.
