blaugelb joint sealing tape 300 BG 2 is a pre-compressed PU foam tape with an acrylate-based impregnation. Due to its special properties, the blaugelb joint sealing tape 300 BG 2 is used for sealing connecting and expansion joints. Additional areas of application are window construction, facade systems, interior work, loft conversion. As per the specifications of DIN 18542, seals reliably against wind, dust and splash water, and can be used in external application if installed where it will be extensively covered.

The pre-compressed blaugelb joint sealing tape 300 BG 2 has a high resilience and expands automatically to the existing joint widths. With just a few tape dimensions, different joint tolerances can be compensated. Component movements are permanently safely absorbed and tears in the joint are avoided. The self-adhesive has an outstanding adhesion on commercially available window profiles and substrates.

The blaugelb joint sealing tape 300 BG 2 can be plastered and painted over and therefore be installed completely hidden. It is suitable for restoration as well as for new construction. Because it is pre-compressed, it can also be applied to joints that already exist.
