weberjoint Premium Silicone Sealant 310ml

Description weberjoint Premium Silicone Sealant is an elastic, acetic curing, 1-component joint silicone sealant that provides permanent elastic after curing. Impervious to mould and resistant against usual household cleaners and disinfectants, ideal for use in areas of high humidity such as bathrooms and kitchens. Excellent adhesion on glass, ceramic, enamel and galvanised metals. weberjoint Premium Silicone is used for sealing around worktops, sanitary ware, for draught proofing around windows and door frames and for perimeter movement joints. weberjoint Premium Silicone Sealant is available in transparent and the following colours, colour-matched to match the weberjoint Premium Tile Grout colours: White, Ice Grey, Platinum, Grey, Silver Grey, Misty Grey, Storm Grey, Slate, Charcoal, Black, Ivory, Jasmine, Limestone, Sandstone, Beige, Natural, Dark Sand, Brown. Substrates: weberjoint Premium Silicone can be used on all usual building substrates such as: galvanised metals, ceramic tiles, aluminium, enamel, glass. Porous surfaces should be primed. Prepare non-porous surfaces with an activator or cleaner. There is no adhesion on PE, PP, PTFE (Teflon®) and bituminous substrates. We recommend a preliminary adhesion and compatibility test on every surface. Constraints: Avoid contact with bitumen, tar or other plasticiser releasing materials such as EPDM, neoprene, butyl, etc. is to be avoided since it can give rise to discolouration and loss of adhesion. The sanitary formula should not replace regular cleaning of the joint. Excessive contamination, deposits or soap remaining’s will stimulate the development of fungi. In an acid environment or in a dark room, a white sealant can slightly turn yellow. Under the influence of sunlight, it will turn back to its initial colour. If left in a dark, closed room away from direct sunlight, silicone can change colour with time. Because of the acid nature, certain metals (e.g. copper, lead) can be affected. Do not use weberjoint Premium Silicone on natural stone such as marble or granite as this may cause staining. Direct contact with the secondary sealing of insulating glass units (insulation) and the PVB-film of safety glass must be avoided. Preparation: Carefully cut the tip of the cartridge and then cut the nozzle to the required size at a 45° angle and fix to cartridge. The nozzle should be cut slightly larger than the joint to be filled. Half-fill baths before sealing around edge and do not drain for 6 hours. Joint dimensions: Min. width for joints: 5mm Max. width for joints: 30mm Min depth for joints: 5mm Recommendation sealing jobs: joint width = 2 x joint depth. Application: With a manual or pneumatic caulking gun, apply the sealant evenly into the joint. Clean with White Spirit or a surface cleaner immediately after use (before curing). Finish with a soapy solution or a finishing solution before skinning. Repair with the same material. When using different reactive joint sealants, the first joint sealant must be completely hardened before the next one is applied. When finished with a finishing solution or soapy solution, make sure that the surfaces are not touched by this solution. This will cause weberjoint Premium Silicone not to adhere to that surface. Therefore, we recommend to only dip the finishing tool in this solution. Do not use weberjoint Premium Silicone in applications where continuous water immersion is possible or on polycarbonate. We strongly recommend not to apply the finishing solution in full sunlight as it will dry very fast in these circumstances.
