Soudatight LQ is a high-quality fibre-reinforced polymer paste that forms an air-tight and vapour-tight elastic membrane after drying.
Use Soudatight LQ for airtight and vapour-tight finishing of penetrations, window, floor-wall, wall-ceiling and roof connections.
The product can be applied very easily with a flat brush.
Cracks up to 2 mm can be easily bridged thanks to the fiber reinforcement.
Soudatight LQ changes color when dry (= visual check).
Properties
Air and vapor tight
Fibre-reinforced, making it suitable for crack bridging up to 2 mm
Very good adhesion to many porous materials
Good adhesion to slightly damp substrate
Remains elastic after curing and very durable
Can be painted over and plastered over after drying
Complies with GEV EMICODE EC-1 PLUS: very low emission
Applications
For airtight and vapour-tight finishing of penetrations, seams, cracks, cracks and openings, wall-floor connections, wall-ceiling connections and window connections such as the inner side of the inner leaf (reveal) and the outer side of the inner leaf (for applying facade insulation).
Instructions
Allow Soudatight LQ to reach room temperature before use. Shake well before use. stir up. Soudatight LQ is applied directly from the packaging to the substrate using a flat brush. The product must be spread/coated on the substrate. Apply the air sealing paste undiluted and evenly in several layers (at least 2) on the substrate to a layer thickness of minimum 1 mm and maximum 3 mm. For the best possible coverage, the product is applied the second time under a different angle. It is recommended to apply the 2nd layer only after skin has formed in the first layer. The application thickness must be measured (wet) using a coating thickness gauge. For window applications, ensure that the air sealing compound forms a seamless membrane of at least 3 mm on the window frame, over the flexible foam up to 5 cm on the reveal of the structural work. The use of masking tape (on the window frame) is recommended. However, this should be removed shortly after applying Soudatight LQ, before curing. For wall connections, ensure that the air sealing compound forms a seamless 15 cm membrane on both surfaces. Soudatight LQ can be removed from materials and tools with water before curing has taken place.
