Soudatight SP - Air and Vapour Tight Membrane
Verified by manufacturer 1 day ago
Soudatight SP is a sprayable airtight liquid membrane.
Application
For airtight, vapour retardant and radon resistant finishing of:
- Wall-floor connections.
- Wall-ceiling connections.
- Wall-wall connections.
- Surfaces (no roof applications).
- Timber frame construction.
- Window connections:
- inside inner leaf (reveal area);
- outside inner leaf (prior to application of the facade insulation).
Description
Soudatight SP is a high-quality water-based polymer paste which, after drying, forms a seamless, airtight and vapour-retardant elastic membrane.
This product allows for a very easy, fast and economical application on larger surface areas and connections in between those surfaces (floor to wall, wall to ceiling, etc). Soudatight SP forms an elastic, air- and vapour tight membrane after drying and is an ideal basis for paint or plaster. Combine with Soudatight LQ for optimal results. Soudatight SP can be applied with a professional airless spraying tools, such as an airless gun connected to either a plunger or a membrane pump.
Features and benefits:
- Air- and vapour tight.
- Radon barrier.
- Stays elastic after curing and very sustainable.
- Forms a seamless membrane.
- Very good adhesion on many porous materials.
- Good adhesion on slightly moist substrates.
- Good adhesion on slightly dusty substrates.
- Can be painted, plastered or taped after drying.
- Meets GEV EMICODE EC-1 PLUS: very low emission.
- Passive House certified.
- M1 emission label.
- ecobau certified: eco-1 label.
