Sanitary silicone sealant
CERESIT CS 25 Sanitary Silicone Sealant, Charcoal, 300 ml
Waterproof joint sealing for the bathroom with lasting protection against mould and mildew.
CERESIT CS 25 is a premium charcoal-coloured sanitary silicone in a 300 ml cartridge for sealing connection joints and expansion joints in wet rooms. It is ideal for the joints between walls and floors and around bathtubs, shower enclosures and washbasins. This 100% silicone bonds strongly to glass, ceramics, enamel, tiles and aluminium without a primer.
Waterproof seal for wet rooms
CERESIT CS 25 offers high water resistance and stops water from lingering in the joints. It seals corner connections and the spots where walls meet floors in bathrooms, kitchens and around sanitary ware. This keeps moisture out exactly where leaks usually start.
Protection against mould, mildew and hot water
CERESIT CS 25 resists hot water and cleaning chemicals, so it holds up on surfaces that are washed often. The silicone has strong resistance to mould and mildew and keeps the joints looking clean. It suits shower enclosures, bathtubs and washbasins in busy bathrooms.
Lasting flexibility and a charcoal tone to match CERESIT grouts
CERESIT CS 25 does not shrink and resists ageing, so the joint stays flexible for years. Its charcoal shade uses durable colours matched to CERESIT grouts for a consistent, finished look. The silicone is also UV resistant, keeping its colour under sunlight.
