## Long description

CERESIT CS25/12 Cement Grey sanitary silicone sealant in a 280 ml cartridge is formulated for flexible, waterproof jointing in sanitary environments. The sealant is intended for use around bathtubs, showers, sinks, washbasins, tiles and plumbing fixtures where a durable, elastic and mould-resistant seal is required. The neutral-cure silicone provides adhesion to common non-porous surfaces and is supplied in a ready-to-use cartridge suitable for caulking guns.
Advantages
The product offers long-term elasticity and waterproof performance designed for wet-room applications. Its cement grey colour blends with grey tiles and fixtures to create discrete seams. The silicone formulation resists mould and mildew growth and adheres to glazed ceramics, enamel, glass, metals and many plastics without primer on properly prepared non-porous substrates. Supplied in a standard 280 ml cartridge, it is compatible with manual or pneumatic caulking guns for controlled application.
Suitable for
Sealing joints between bathtubs, shower trays and tiled walls
Sealing around sinks, washbasins and plumbing fixtures
Sealing movement joints in wet rooms and kitchens
Sealing between tiles and non-porous surfaces such as glass or enamel
When it may not be suitable
This sanitary silicone is designed for non-porous and typically smooth surfaces. It is not formulated for continuous immersion applications where special underwater or structural sealants are required. The product may not adhere reliably to highly porous, powdery or poorly prepared substrates without proper surface treatment or primer.
Key specifications
Volume: 280 ml cartridge
Colour: cement grey
Type: sanitary neutral-cure silicone sealant
Properties: flexible, waterproof, mould-resistant
Typical substrates: glazed ceramics, enamel, glass, metals, many plastics
How to use
Prepare joint surfaces by cleaning and drying thoroughly; remove old sealant, contaminants, grease and loose material. Fit the cartridge into a suitable caulking gun and cut the nozzle to the required bead size. Apply an even continuous bead into the joint, tooling the sealant within the product's skin time to ensure adhesion and smooth finish. Allow cure time as specified by the manufacturer before exposing the joint to water; curing speed depends on ambient temperature and humidity. Do not use on damp surfaces or where the joint is in permanent water immersion.
What to consider before purchase
Ensure cement grey colour matches tiles and fixtures in your project
Check compatibility with the specific substrate; test adhesion on plastics if unsure
Confirm the required cartridge volume (280 ml) is sufficient for the planned work
Allow for adequate ventilation during application and curing
Usage recommendations
For best results, apply at room temperature to clean, dry joints; tool the bead within the product's skin time and allow full cure before exposing to water. Use a mould-inhibiting tape or cleaner in heavily damp environments and perform a small adhesion test where substrate compatibility is uncertain.
