prodomo BLUE air tight sealant

High performance air tightness sealant to bond membranes & window tapes to block, concrete, steel and timber. prodomo BLUE is mainly made for internal applications. Once it´s cured, it creates a permanent elastic seal, which withstands the common mechanical load for air tightness applications in the construction business. An additional mechanical support (e.g. fixing strip) is not required for standard applications.


prodomo BLUE can be applied in two bonding methods - wet or dry.

Wet application

The sealant has to be applied to the dry substrate with a bead of approx. 8mm thickness. Afterwards the membrane or window tape has to pushed gently into the bead, by allowing a remaining thickness of 2-3mm.

Dry application

The sealant has to be applied around 24 hours before the membrane or tape, to create the required hardness grade. prodomo BLUE is still tacky and the membrane/ tape can be applied with a certain contact pressure. Please allow a remaining thickness of 2-3mm for the sealant.
