Limits & notes
The tape is not suitable for walkable or drivable substrates. The substrate must be dry, free of frost, grease and silicone as well as abrasion-resistant, otherwise the tape does not adhere reliably. Porous or dusty surfaces require a primer coat beforehand.
Application & tips
Clean the substrate and let it dry; treat porous or dusty surfaces with a primer coat (approx. 200 ml/m²). The application temperature is 5 to 45 °C, measured at air and substrate. At low temperatures, storing the roll beforehand at room temperature improves adhesion. Lay on the tape, press on firmly and avoid air bubbles. Overlap several lengths by at least 50 mm. Store rolls dry, protected from direct sun at 10 to 30 °C, standing on the cut edge. The tape is not sensitive to frost; processing within 12 months is recommended.
Frequently asked questions
Do I have to warm the tape?
No, it is applied cold. At low temperatures it helps to store the roll beforehand at room temperature.
How far must lengths overlap?
With several strips at least 50 mm.
Do I need a primer coat?
Only on porous or dusty substrate, at approx. 200 ml/m². Not on smooth, clean surfaces.
Can I walk over the tape?
No, walkable or drivable substrates are not suitable.
Which width fits?
50 mm for narrow joints and cracks, 75 and 100 mm for gutters and connections, 200 mm for wide connections and large overlaps.
