Ceresit CS 25 Sanitary Silicone Sealant, Manhattan, 280ml

Ceresit CS 25 Sanitary Silicone Sealant in Manhattan color is a professional-grade, one-component acetoxy-curing silicone designed for sealing joints in areas exposed to high humidity. Featuring advanced MicroProtect technology, this sealant provides long-term protection against the growth of mold and fungi, making it an ideal choice for maintaining hygiene in wet rooms. Its excellent adhesion to non-porous surfaces such as ceramic tiles, glass, and sanitary ware ensures a durable, flexible, and watertight seal that withstands the rigors of daily use in kitchens and bathrooms.

Advantages

The primary benefit of Ceresit CS 25 is its superior resistance to biological degradation, which keeps joints looking clean and fresh for an extended period. The silicone remains permanently flexible, allowing it to accommodate minor movements in building structures without cracking or losing its seal. Its high water resistance and chemical stability make it suitable for demanding environments where moisture is constant. The Manhattan color provides a neutral, aesthetic finish that complements various tile designs and sanitary installations, ensuring a professional appearance.

Suitable for

• Sealing expansion joints in bathrooms and kitchens
• Filling gaps between ceramic tiles and sanitary fixtures
• Sealing joints in shower cabins and around bathtubs
• Applications in humid indoor environments

This product is not suitable for use on natural stone surfaces, such as marble or granite, as it may cause staining. It is also not recommended for applications involving structural glazing, contact with food, or surfaces that require overpainting, as silicone sealants are generally not paintable.

Before application, ensure that the surfaces are clean, dry, and free from dust, grease, or old sealant residues. Use masking tape along the edges of the joint to achieve a clean line.

Smooth the surface with a jointing tool or a finger dipped in soapy water within the skin-formation time.

What to consider before purchase

• Compatibility with the surface material
• Color matching with existing grout or tiles

For optimal results, ensure the joint is properly sized to allow for movement and avoid applying the sealant in temperatures below +5°C. Always allow the silicone to cure fully before exposing it to direct water contact.
