What it is
Elastoplastic sealant adhesive based on elastomeric resins that adhere to bitumen and the most common building materials, even on wet surfaces, forming a flexible joint. Fields of application Specifically for the repair of bituminous membranes and the bonding and sealing of coverings, insulating materials (except EPS and XPS), roof tiles, tiles and plastic surfaces (without plasticisers). It allows the sealing and waterproofing of joints, cracks, various types of breakage and swelling, underbody coating of vehicles, caravans, etc. Adheres to concrete, zinc, wood, aluminium, sheet metal, etc., even when damp. Good occasional resistance to solvents, except mineral oils and spirits. It cannot be overcoated.
Sealant is a paste product, in cartridges or tubes, that fills and seals joints and gaps, either remaining elastic or curing hard (silicones, polyurethanes, acrylics, hybrids, construction adhesives).

Used for waterproofing roofs, terraces and below-ground structures, for structural and assembly bonding and for sealing joints, gaps and service penetrations.
How to use it
Clean and dry the joint edges, insert backer rod if needed and mask the edges with masking tape. Cut the nozzle at an angle to the width of the joint, extrude the product with the gun in a continuous bead and tool it with a wet spatula before it skins over. Remove the tape immediately and allow the full curing time before stressing the joint.
