Practical benefits

Soudal Silirub MA neutral silicone: You seal marble, granite, and porous natural stone without the risk of migration staining or discolouration.
Permanently flexible joint: It stays flexible after curing, ensuring reliable movement accommodation between various construction materials.
Mould resistant protection: The integrated fungicidal formula helps you maintain clean and hygienic seals in sanitary areas and kitchens.

In a nutshell

The right choise for

With Soudal Silirub MA, you achieve a clean, long-lasting seal without the risk of edge contamination or staining on porous natural stone such as marble, granite, and bluestone. This neutral, elastic silicone sealant is formulated specifically for sensitive substrates where standard silicone can cause discolouration. Thanks to its mould-resistant fungicidal action, you can seal sanitary joints around washbasins, shower trays, and bath rims with complete confidence. Once cured, the sealant remains permanently elastic and resistant to uv exposure and weather, absorbing movement between construction materials without shrinking or cracking. You can apply it smoothly using a manual or pneumatic caulking gun for both indoor and outdoor jobs.
