Isopasta (Blue Primer) is a type of water-soluble bituminous compound used for coating surfaces or priming them for the installation of Isogam prefabricated insulation.
Indications for use:
Primer can be used to prepare the surface for insulation. Furthermore, as this product is available in either a paste or liquid form, primers also make it possible to cover inaccessible surfaces.
The installation of prefabricated insulation on surfaces that are not smooth, or which have dust particles, will not be of a satisfactory quality.
