Description

Mapesil AC – Premium Silicone Sealant for Bathrooms, Kitchens & Tiles

Mapesil AC is a high-performance silicone sealant by Mapei, designed for sealing bathroom tiles, kitchen splashbacks, and other surfaces exposed to water and humidity. With its excellent adhesion, flexibility, and mould-resistant formula, Mapesil AC ensures long-lasting joints in domestic, commercial, and industrial applications.

Where to Use Mapesil AC

  • Sealing joints between sanitary ware, sinks, and ceramic wall tiles
  • Expansion joints in swimming pool tiles
  • Glazing, window frames, and stained glass assemblies
  • Air ducts, service pipes, tanks, and boilers
  • High-stress environments with chemical or thermal exposure

Why Choose Mapesil AC?

  • Available in 34 colours + transparent to match Mapei grout ranges
  • Highly elastic – ±25% joint movement
  • Resistant to mould, mildew, and water damage
  • Durable in extreme climates (-40°C to +180°C)
  • EC1 Plus certified – very low emissions

Key Advantages

  • Wide colour range

Recommendations

  • Not suitable for joints with light-coloured natural stone (risk of staining).
  • Avoid use on limestone or acid-sensitive surfaces – use Mapesil LM instead.
  • Not recommended for bituminous substrates or highly plasticised materials.
  • Do not use for aquariums.
  • For floor joints with heavy traffic, use polyurethane alternatives like Mapeflex PU 45 FT.
