Mapei Mapesil AC

Product Code: MAPAC-1-310-CART

Mapei Mapesil AC is an acetic-crosslinking silicone sealant suitable for sealing glass, ceramic and anodised aluminium.

  • Forming a perfectly elastic gasket between different elements in building, mechanical engineering, ship- building, automobile, manufacturing, etc.

Some application examples

  • Sealing joints in wall and floor coverings of ceramic and cement, provided they are not subject to heavy abrasion.
  • Sealing joints between sinks or sanitary ware and ceramic tiles in kitchens, bathrooms and showers with colours coordinated with the grouts.
  • Sealing expansion joints in swimming pools.
  • Assembling compositions of glass tiles and artistic stained glass windows.
  • Sealing glazing of door and window frames.

  • Sealing materials of different thermal exposure coefficient.
  • Adhesive and sealant for general use.


Technical Characteristics

Mapei Mapesil AC 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. It crosslinks following exposure to atmospheric humidity at ambient temperatures, and forms an elastic product with following properties:

  • excellent durability. Seals remain unchanged even after many years exposure to climatic extremes, industrial pollution, sudden temperature changes and immersion in water;
  • high elasticity;
  • excellent bonding to glass, ceramic and anodised aluminium;
  • mildew resistant;
  • waterproof and permeable to vapour;
  • resistant to chemical agents;
  • flexible down to -40°C and resistant to temperatures at +180°C;
  • easily workable;
  • in compliance with ISO 11600 norm, it is classified as F-25-LM.
  • in compliance with numerous international standards.
  • in compliance with EN 15651-1, EN 15651-2, EN 15651-3 and CE-marking.



  • Do not use Mapesil AC for joints in exterior between ceramic tiles and light-coloured natural stone because dirt could accumulate by the joints. Use Mapei Mapesil LM.
  • For sealing surfaces sensitive to acids such as lime stone, use a neutral silicone sealant (e.g. Mapesil LM).
  • The use of 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.
  • The resistance of Mapesil AC to chemical agents is generally excellent; however, due to the numerous products and working conditions to which Mapesil AC can be applied, it is always advisable to do a sample test in cases of doubt.
  • Do not use Mapesil AC to seal aquariums.
  • 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.
