CERESIT CS 25 MicroProtect sanitary silicone sealant in a 280 ml cartridge is formulated for sealing sanitary and bathroom joints with a jasmine scent. The product delivers a flexible, waterproof seal intended for areas exposed to moisture, such as seams between bathtubs, sinks, showers, tiles and sanitary fittings. The MicroProtect technology reduces the risk of mould and mildew growth on the cured surface, supporting longer-lasting hygienic joints in wet environments.
Advantages
The sealant cures to a durable elastic silicone joint that accommodates small movements while maintaining a watertight barrier. Its MicroProtect formula provides protection against mould and mildew, decreasing microbial staining and maintenance frequency. The jasmine scent masks typical silicone odour during application and initial curing, improving user experience in enclosed bathroom spaces. The cartridge format is compatible with standard caulking guns and allows measured application on vertical and horizontal joints.
Suitable for
- Sealing joints between bathtubs, shower trays and bathroom tiles
- Sealing around sinks, washbasins and sanitary fittings
- Sealing expansion and connection joints in wet rooms and kitchens
- Repairing existing silicone joints and finishing tile edges
When it may not be suitable
This product is a sanitary acetoxy or neutral-cure silicone formulated for indoor wet-area joints and is not intended for structural bonding or heavy-load mechanical joints. It is not suitable for continuous water immersion (for example, inside water tanks) where specific underwater or potable-water approved sealants are required. Surfaces heavily contaminated with old sealant, grease, or loose substrates should be prepared or replaced before application to ensure adhesion.
Key specifications
- Volume: 280 ml cartridge
- Type: sanitary silicone sealant with mould-resistant MicroProtect formula
- Finish: flexible, elastic cured joint
- Scent: jasmine during application and initial cure
- Typical applications: bathroom and sanitary joints, tile edges, fittings
How to use
Ensure surfaces are clean, dry and free of dust, grease or old sealant residue. Cut the cartridge nozzle at an appropriate angle and load it into a standard caulking gun. Apply a continuous bead of sealant along the joint, maintaining steady pressure for an even finish. Smooth the joint within the tooling time using a suitable tool or a wet finger for a neat profile. Allow the sealant to cure undisturbed according to ambient temperature and humidity; avoid contact with water until the skin has formed and full cure is achieved.
What to consider before purchase
- Ensure the colour and jasmine scent meet project or user preferences
- Confirm compatibility with substrate materials (ceramic, glazed tiles, most sanitary plastics and metals)
- Verify that the joint type is suitable for silicone (not for porous masonry without primer)
- Plan for adequate ventilation during application and curing
Usage recommendations
For durable, hygienic results in bathrooms: prepare joints by removing old sealant, clean with a suitable cleaner, and use masking tape for sharp edges. Tool the sealant immediately after application and allow full cure before exposing the joint to heavy moisture or permanent water contact.
