FLK Liquid Corner

The blaugelb FLK Liquid Corner is a one-component liquid plastic based on polyurethane for localised sealing of floor-level elements in areas in contact with the ground, balconies and loggias in accordance with DIN 18531 and DIN 18533.

It is mixed with fibreglass fibres and thus has a firmer structure and increased stability, for example in hard-to-reach corners and grooves where the use of the seal with fleece reinforcement as the substrate is not possible.

The blaugelb FLK Liquid Corner is part of the blaugelb FLK Sealing System and is only intended for localised use, not for large-area sealing according to ETA.
