It has excellent adhesive properties to most common building substrates, weatherproof and suitable for indoor and outdoor applications. It is available as a 600mL sausage in a range of colours. Uses Ideal for elastic joint sealing of expansion and construction joints between common building materials in vertical and horizontal surfaces such as; x Expansion Joints in precast elements x Perimeter seals around windows and doors x External wall and cladding joints x Weatherproofing joints between brickwork, masonry, wood concrete or metal frames. x Joints in walls, balconies, around window or door frames. x Joints in bridge and balcony parapets x Retaining walls x Roofing. x Acoustic rated walls Features/Advantages x High flexibility with +/-25% joint movement capability x Low modulus of elasticity x Excellent resistance to aging and weathering x No shrinkage during curing x Excellent adhesion on common building materials such as concrete, masonry, brick, ceramic tile, metals, soft wood, hardwood and some plastics x Certified according to ISO11600/F/25LM and DIN18540/F x Will not degrade acoustic walls that meet the BCA requirements Instructions for Use/Application Instructions The following should only be used as a guide and the installer should apply all Australian Standards, BCA/NZBC requirements, and best practices when installing. x Surface must be clean, dry and free from oil, grease, release agents, dust and loose material. x Install backing rod to correct depth apply masking tape as required. x Cut the end of the sausage and insert into a Selleys sausage gun. x Extrude sealant into the joint such that it is in full contact with the sides of the joint. Avoid overlapping of sealant to eliminate entrapment of air. x Smooth sealant with spatula forcing the sealant into the joint for better contact with the sides. x Painting with water based paints is possible after curing. If solvent based paints are used; prime first with water based primer. Priming Selleys Flexiseal generally has good adhesion properties without priming to common building materials indicated. For some plastics and pre painted surfaces; priming may be required and a Pre-test to ensure suitable adhesion is recommended. Joint & sealant dimensions The optimum width to depth ratio for expansion joint sealing is 2:1. Minimum joint width and depth is 6mm. For joint widths up to 12mm, use a width to depth ratio of 1:1 For joint widths greater than 12mm, use a width to depth ratio of 2:1
