The KD FLEX 20 adhesive sealant Fischer combines sealing and bonding functions in a single professional product in white, packed in 290 ml. It features an anchorage depth of 10 mm and a storage stability of up to 18 months, details that make it a practical solution for elastic fixings and joints. Supplied as a single piece.
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).
What it is for
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.
