Mapei Mapesil AC 111 Solvent-Free Silicone Silver Grey 310ml

Product Information

For sealing floor joints subject to heavy traffic, use a polyurethane (e.g. Mapeflex PU 45 FT) or epoxy-polyurethane (e.g. Mapeflex PU20) sealant.

Do not use Mapei Mapesil LM for sealing doors subject to intense traffic – (use Mapeflex PU45, Mapeflex PU20 or Mapeflex PU21). Mapei Mapesil AC Silicone is a one-component, acetic crosslinking, solvent-free silicone sealant, available coloured or transparent. It is a thixotropic paste which is easily trowellable both horizontally and vertically. Mapei Mapesil AC Silicone crosslinks following exposure to atmospheric humidity at ambient temperatures, and forms an elastic product with following properties:Mapei Mapesil LM is particularly suitable for surfaces sensitive to acids on which conventional neutral or acid sealants normally provoke changes in colour or staining of the substrate. Forming a perfectly elastic gasket between different elements in building, mechanical engineering, ship-building, automobile manufacturing, etc.

To control the depth of the joint and to prevent Mapei Mapesil AC Silicone from adhering to the base, the bottom of the joint should be filled with a sized Mapefoam, a polyethylene cord Thanks to the low modulus of elasticity of Mapei Mapesil LM Silicone, it is suitable for sealing internal and external fillet and expansion joints, including those subject to high levels of movement when in service, between: Pre-fabricated panels, window/door fittings and wall surrounds, pipe-work and vertical walls, similar and/or different types of coating materials. It is also suitable for sealing joints in doors with limited pedestrian traffic. The use of Mapei Mapesil AC is not recommended on highly plasticised material or on bituminous surfaces because of the release of substances that reduce bonding and penetrate into the sealant, altering the colour and resistance. Mapei Mapesil LM Silicone delays the formation of surface mould. Mapei Mapesil LM generally offers good resistance to chemical agents. However, because of the wide range of products and service conditions, if in doubt carry out preliminary tests beforehand. Where Mapei Mapesil AC is to be applied in areas of continuous immersion, i.e. inside a swimming pool tank, the joints must be primed using Mapei Primer FD.Make sure your tiling project’s joints and seals stand up to everyday wear and tear with Mapesil, an acetic-crosslinking silicone sealant from the world’s leading manufacturer of tiling grout, adhesives and sealing products, Mapei. When Mapesil LM is constantly immersed in treated water typically found in swimming pools its physical-mechanics may be affected prematurely. Given the wide range of products used to treat water and the actual quantities employed, its suitability over long periods may only be guaranteed following specific laboratory testing. The resistance of Mapei Mapesil AC to chemical agents is generally excellent; however, due to the numerous products and working conditions to which Mapei Mapesil AC can be applied, it is always advisable to do a sample test in cases of doubt. For sealing surfaces sensitive to acids such as lime stone, use a neutral silicone sealant (e.g. Mapesil LM).
