Description
Natural Stone Silicone Sealant
Silirub MA is a premium low modulus neutral cure silicone sealant specially developed for use on marble, granite, limestone and other natural stone surfaces. Its non-staining formulation prevents migration of plasticisers into porous substrates, making it ideal for applications where conventional silicones may cause staining or discolouration.
Designed for both construction and sanitary applications, Silirub MA provides a permanently flexible, waterproof seal with excellent adhesion to natural stone and many common building materials. The sealant is highly resistant to UV exposure and weathering, making it suitable for both interior and exterior use.
Containing ZnP fungicidal protection, Silirub MA offers excellent resistance to mould growth, making it an ideal choice for kitchens, bathrooms, glazing applications and expansion joints involving natural stone.
