– Building- and construction joints, especially in sanitary and humid places.
– For sealing of joints in sanitary and other moist rooms between, e.g. showers, bathtubs and (tiled) walls, between walls and washbasins, between floors and toilet.
– Top sealing in glazing.
– Joints in building products from aluminium and finished materials.
– Sealing in air conditioning systems.
– Because of the acid nature, certain metals (e.g. copper, lead) can be affected.
– Do not use on natural stones like marble, granite (staining). Use Soudal Silirub MA or Silirub+ S8800 for this application.
– Do not use on polycarbonate. Use Silirub PC instead.
– The sanitary formula should not replace regular cleaning of the joint. Excessive contamination, deposits or soap remainings will stimulate the development of fungi.
– A total absence of UV can cause a colour change of the sealant.
– In an acid environment or a dark room, a white sealant can slightly turn yellow. Under the influence of sunlight, it will turn back to its initial colour.
– We strongly recommend not to apply the Finishing Solution in full sunlight as it will dry very fast in these circumstances.
– When finished with a finishing solution or soapy solution, ensure that this solution does not touch the surfaces. This will cause the sealant not to adhere to that surface. Therefore we recommend to only dip the finishing tool in this solution.
– Do not use in applications where continuous water immersion is possible.
