Process for insulating and sealing essentially flat roofing and coating used in this process
A process for insulating and sealing roofing comprises coating the substrate ( 2 ) with a liquid or viscous composition ( 3 ) that is based on modified bitumen or a bitumen/polyurethane mixture by covering rough spots ( 4 ) and by filling the hollows or emergent cavities ( 4 ′) that are present on t...

| Zusammenfassung: | A process for insulating and sealing roofing comprises coating the substrate (
2
) with a liquid or viscous composition (
3
) that is based on modified bitumen or a bitumen/polyurethane mixture by covering rough spots (
4
) and by filling the hollows or emergent cavities (
4
′) that are present on the surface of the substrate (
2
), then applying the insulating layer (
1
) or individual elements that are intended to form the insulating layer (
1
) on the coated surface of the substrate (
2
) before the previously applied coating layer (
3
) solidifies, whereby the coating layer (
3
) forms, after drying or polymerization, a water-vapor barrier and an agent for adhesion of insulating layer (
1
) to the attachment substrate (
2
), and, finally, applying to insulating layer (
1
) a sealing coating (
6
). |
