LD925 is a sprayable, water-based elastic liquid membrane which forms an air seal after drying, with a moisture variable diffusion resistance.

Usage/purpose

Specifically designed for building applications where a high level of air tightness is required (eg Passive House). Apply for air and vapour sealing of floor-to-wall, wall-to-ceiling and various other joint connections. Forms a seamless membrane with very good adhesion to many porous surfaces and most typical building materials such as steel, concrete, stone, wood and aluminum. Can be painted, plastered or bonded to after drying. Due to the moisture-variable diffusion resistance, the seal can be applied to both the inside and outside of the construction.

Do not use where continuous standing water or hydrostatic
pressure is likely to be present.
Do not apply during rainfall or if rain within 24 hours of
application is expected.
Non-staining with most substrates, however where this
may be of concern, consult Tremco CPG UK for further
information.
The coating does not adhere well to bitumen, glass, V2A
(stainless) steel, EPDM, PTFE and PE films.
Store the buckets frost-free.
Temperature of the substrate and surroundings have a
large influence on drying time and elasticity.
Ensure sufficient layer thickness for specific details,
external/sharp corners and other imperfections. Deal with waste disposal according to government
regulations.
