## Summary description

Koelner Piana montażowa is a 660 ml polyurethane assembly foam (model RPS-K) supplied in a flexible nozzle format for controlled application. It is intended for sealing, filling gaps, thermal and acoustic insulation, and bonding in construction and installation tasks. Suitable for door and window installation, wall cavities, pipe penetrations and general gap filling.

## Long description

Koelner Piana montażowa 660 ml RPS-K is a polyurethane assembly foam supplied in a flexible nozzle format for controlled, one-handed application. Designed for sealing, filling and insulating joints and cavities, this foam provides thermal and acoustic insulation as well as adhesive support for installation tasks. Its nozzle-applied design helps reach narrow or recessed gaps and ensures more precise dosing compared with standard cans.
Advantages
The nozzle-applied format allows accurate application and reduces waste while maintaining consistent foam expansion and curing. The foam offers combined thermal and sound insulation properties and provides good adhesion to common building substrates such as brick, concrete, wood and many plastics. Cured foam is resilient and fills irregular voids, improving airtightness and reducing heat loss and draughts when used around frames and penetrations.
Suitable for
Installing and sealing door and window frames
Filling gaps and cavities in walls and around pipe penetrations
Thermal and acoustic insulation of joints and voids
Bonding and stabilising lightweight elements during installation
Key specifications
Formulation: single-component polyurethane assembly foam
Packaging volume: 660 ml in a flexible nozzle applicator
Application method: nozzle-applied foam suitable for one-handed use
Performance: controlled expansion for filling irregular gaps; provides thermal and acoustic insulation
Curing: moisture-cured foam that hardens to a resilient closed/partially open cell structure
Substrate compatibility: bonds to brick, concrete, wood and many common construction plastics
Storage and handling: store upright in a cool, dry place away from direct heat sources
How to use
Prepare surfaces by removing dust, grease and loose particles; dampen very dry surfaces slightly with water to improve adhesion and curing. Shake the can if applicable, attach the flexible nozzle and apply foam from the bottom of the gap moving upward to allow uniform filling. Fill gaps partially to allow for expansion, and trim excess cured foam with a knife or saw once fully cured. Clean uncured foam from tools and surfaces using a suitable solvent or foam cleaner; cured foam must be removed mechanically.
Usage recommendations
Use appropriate protective gloves and eye protection during application. Avoid applying foam at temperatures outside the recommended working range and ensure adequate ventilation. For load-bearing fixes or structural bonding, use mechanical fasteners in addition to foam according to project requirements and applicable standards.
