T-Expand Strip
Pre-compressed sealant strip made of impregnated PUR (Polyurethane) with a adhesive strip on the underside for quick and easy installation. The outer side is diffusion-open but protected against driving rain and waterproof up to 600 Pa.
Self-adhesive
Driving rainproof (600 Pa)
Vapor permeable
UV protected
Application Area
For jointing and sealing primarily externally in facades or frames. The sealing tape provides a diffusion-open weatherproof exterior. Works on substrates such as wood, steel, sheet metal, concrete, and most
plaster. Can be exposed to weather and sunlight for a long time.
Installation
The installation is self-adhesive. After fixing, the tape self-expands to completely seal and close the joint. For complete information, see the installation instructions!
Important!
- The applicable surface must be clean and dry, free from loose particles, grease, or silicone. The joint surfaces should be even and smooth.
- Columns should be parallel and perpendicular in depth to avoid angled surfaces. Some irregularities can be absorbed by the tape, but long lines with angles provide the tape with an insecure fixation.
- In stone/brick facades with uneven joint surfaces, the joints should be filled and smoothed to achieve flat surfaces.
- Mount the strip a few mm into the gap so that pressing or dripping water on the outside is not directed straight into the strip.
- At colder installation temperatures (and/or at low humidity), the expansion time can be significantly extended. Up to several days in some cases. Increased temperature (and humidity) or gentle heating accelerates the process. To increase the expansion time, the tape can be stored cold before installation.
- After cutting the tape to the correct length, reseal the roll with tape or a locking clip at the tape end.
- In case of leaks in the completed installation (such as corners or joints), supplement and seal with T-Fix sealant. This can be done from the outside or inside after full expansion.
- Rolls should be stored protected from heat and sunlight.
- For window or door installation, we recommend using a so-called secondary seal (underlying waterproof layer) such as Flexseal-T at the bottom of the opening. The tape is intended to protect the frame and is installed before the window or door installation.
