What it is
is a one-component, low-modulus, non-sagging SiMP – Silyl Modified Polymer sealant for construction. It cures under the influence of atmospheric moisture to form a high-performance compound with permanent elasticity and high resistance to ageing and weathering. Free of solvents and isocyanates. Application areas: it is a versatile, high-performance building sealant for expansion and construction joints in vertical applications, joints in prefabricated elements, external walls and cladding joints. Suitable for sealing metal roofs and gutters, bridge and balcony parapets, and for waterproofing joints between bricks, blocks, masonry, wood, concrete, metal and window and door frames.
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.
