  • MAPESIL AC – Internal Silicone Sealants – All Colours

    £5.59

     

    MAPESIL AC is a high quality, mould resistant sealant, which is ideal for internal use but can also be used in external applications. The product comes in a 310ml cartridge & has a range of 42 colours to choose from. Mapei also colour match this product to their Ultracolor plus grout range, creating a seamless transition between grout & silicone lines when used together.

    To view the Ultracolor plus range – please click here.

    RECOMMENDATIONS

    – Mapesil AC should not be used in applications between joints of ceramic tiles & natural stone of light colour externally. Use Mapesil LM, which can be viewed here.
    – Should not be used for sealing of surfaces sensitive to acids, such as limestone. Again, use Mapesil LM.
    – Do not use on bituminous surfaces or highly plasticized material.
    – Mapesil AC’s chemical resistance to agents is typically excellent. However, we advise you to check the technical data sheet or do a small test.

     

    We have a number of tools on our website that would assist with the application of this product. We would recommend using a PC Cox Skeleton Gun to apply & a Bond-it Tooling Kit to aid in providing a professional finish.
