Description: Solvent based elastomeric-bituminous sealant/adhesive
Fields of application: It is a bituminous sealant studied to be spread with suitable manual or mechanic spray guns in two welding seams, between the membrane over-lapped parts, to reach a perfect cold glueing between them. Suggested for glueing of sheath on Canadian roofing tile type sheath. It is not suitable for glueing insulating polyurethan and polystyrene blooms, due to the presence of aromatic solvents rapidly etching the panels.
Suggested for fast localized repairs of old membranes, for sealing between membranes and vertical concrete, and to seal chimney caps and lanterns.
Application:
It is necessary that the surfaces to be treated are dry, clean and free from oils and chalking powders. The product is ready to use, to be spread on the substructure with suitable manual or mechanic spray guns. Should any blowing occurr on old polymer-bitumen membranes, it can be eliminated by localized crooshatching on the membranes, glueing again the four edges on the whole surface with Viaseal. Tools to be cleaned using common synthetic or nitrous diluents.
