How to use


Clean the substrate before fixing the sealing tape. The areas to be sealed must be load-bearing, sound and free from dust, release agents, oil, grease, sintered layers and other substances that may impair adhesion. Particularly suitable for this purpose is TEROSON PR Primer M+S.


After removing the release film, press TEROSON TA ALU firmly down to the substrate using a hard rubber roller. Make sure to fix the tape in such a way that no capillary water can be absorbed and air pockets are avoided. Especially in overlapping and edge areas, press the strips firmly down with the TEROSON hard rubber roller.

Frequently asked questions

We recommend a TEROSON primer for mineral, weakly bound but stable substrates. In adverse weather conditions, it is always necessary to use an adhesion promoter on mineral substrates.

The adhesive width for the frame profile is 20-30mm, this is already specified by the self-adhesive strip of the respective sealing foil. The adhesive width varies from 30-50 mm depending on the structure of the product, the current technical data sheet for the product is decisive. Note: Depending on the project, the adhesive width can be increased on smooth, clean and stable substrates after consultation with the TEROSON facade expert. Also can be lower.

Overlapping film joints are glued on top of each other with a width of approx. 50 mm. An additional mechanical fastening of the TEROSON sealing foils is generally not required.
