General airtightness of any joints or connections e.g. floor to wall joints, wall to ceiling joints. Can also be used as an alternative to SWS Inside Tape if used as part of a system with Soudafoam Window & Door SWS.


    Soudatight LQ is a high-quality fibre reinforced polymer membrane which forms an air and vapour tight elastic membrane after drying. The product can be quickly and easily applied with a brush in the desired layer thickness on almost any mineral substrate. Fills cracks up to 5 mm due to fibre-reinforcement. Once dried a second coat (or more) can be applied if required, after which it can be painted or plastered over. The black variation changes colour after drying, from blue to black. The white version does not have this colour indication.
