Ardex Flashing Tape 100mm x 4.7m
The butyl detailing tape for corners, pipes and outlets under ARDEX Weldtec sheet membranes.
ARDEX Flashing Tape is a black butyl rubber mastic tape on a polyethylene backing. It is the detailing tape for the ARDEX Weldtec membrane system. Cut it to size, bond it to the prepared substrate with ARDEX WA 98 Adhesive, then glue or heat-weld the Weldtec membrane over it.
What it's for
- All external corners before the Weldtec membrane goes down
- Pipe penetrations
- Drainage waste outlets
Why waterproofers buy it
- Extremely malleable, so it works into tight corners and around pipes
- Creates a continuous, watertight detail in critical areas
- Weldtec membrane glues or heat-welds straight to it
- Non-hazardous chemical, non-dangerous goods

Technical overview
Key applications
- External corners prior to ARDEX Weldtec membrane installation
- Pipe penetrations prior to ARDEX Weldtec membrane installation
- Drainage waste outlets prior to ARDEX Weldtec membrane installation
- Detailing critical areas within an ARDEX Weldtec membrane system
ARDEX publish no technical data sheet for this product, so there is no published application temperature, service temperature, substrate list, shelf life or performance data for it. It is a detailing tape used within an ARDEX Weldtec membrane system: it is cut to size and adhered to the prepared substrate with ARDEX WA 98 Adhesive, and the ARDEX Weldtec membrane is then glued and or heat-welded to it. The safety data sheet classifies it as a non-hazardous chemical and non-dangerous good, but still directs that it be used in a well-ventilated area, that contact with incompatible materials be avoided, and that it be stored in a cool, dry, well-ventilated area away from oxidising agents and strong acids and bases.
