reca PURFLEX is a newly developed, one-component, highly elastic and externally tested (by MPA Bau Hannover) gun foam for RAL-compliant filling.

Field of Application:

For RAL-compliant filling, soundproofing and insulation of window connection joints and filling door frame connection joints. The foam can absorb structural movement more effectively thanks to its high elasticity of over 30%. Excellent adherence to concrete, masonry, stone, plaster, wood, fibre cement, metal and many plastics (polystyrene, PUR rigid foam, polyester, rigid PVC).


The substrates must be stable, clean and free of dust, grease and release agents. Moisten dry substrates with water (spray). The ideal application temperature is +20 °C. Observe the operating instructions of your gun. Shake the can well at least 30 times before screwing onto the assembly gun and after work interruptions. Moisten between applications. Do not tilt or overtighten when screwing onto the gun.
Remove any fresh splashes of foam immediately using RECA S 25 PU universal cleaner (article no. 0898 225 2). Cured foam can only be removed mechanically.
