Sanitary silicone sealant CERESIT MicroProtect CS 25 Toffi 280 ml

CERESIT MicroProtect CS 25 Toffi is a sanitary silicone sealant supplied in a 280 ml cartridge for sealing and maintenance of sanitary joints. Formulated to provide elastic, waterproof sealing with resistance to mold and mildew, this sealant adheres to glazed ceramics, enamel, glass and many coated surfaces commonly found in bathrooms and kitchens. The neutral-cure composition is intended for sanitary fixtures and will help preserve joint integrity under normal household humidity and wet conditions.

Advantages

The sealant delivers durable elastic sealing that compensates for minor substrate movement and thermal expansion. Its MicroProtect technology reduces the risk of mold and mildew growth on the joint surface, supporting hygienic conditions in wet rooms. It offers good adhesion to common sanitary materials, cures to a flexible bead, and is supplied in a standard 280 ml cartridge compatible with manual or pneumatic caulking guns.

Suitable for

• Sealing joints around bathtubs, showers and washbasins
• Sealing joints in tiled walls and splashbacks in kitchens and bathrooms
• Maintenance of sanitary fixtures and replacement of aged silicone seals
• Sealing between ceramic tiles, enamel surfaces and glass installations

When it may not be suitable

This sanitary silicone is designed for typical bathroom and kitchen joints; it may not be suitable for applications requiring paintability or where solvent-based adhesives are specified. It is not intended for structural bonding or for use on some porous, uncoated substrates without a primer. Surfaces heavily contaminated with old sealant, grease or loose material should be cleaned or prepared before application.

Key specifications

• Volume: 280 ml cartridge
• Type: sanitary silicone, neutral cure
• Properties: elastic, waterproof, mold- and mildew-resistant surface protection
• Suitable substrates: glazed ceramics, enamel, glass, many coated surfaces
• Curing: forms a flexible sealing bead after curing

How to use

Ensure all surfaces are clean, dry and free of dust, grease and old sealant. Cut the cartridge tip to the required bead size and load into a caulking gun. Apply a continuous bead into the joint, maintaining steady pressure to avoid gaps. Smooth the fresh sealant with a compatible tool or a wet finger within the skin time to produce a neat finish and ensure contact with both joint faces. Allow the sealant to cure fully according to ambient temperature and humidity before exposing to water.

What to consider before purchase

• Check compatibility with the specific substrate and any primers required for porous or coated surfaces
• Confirm the color (Toffi) matches or complements surrounding materials
• Ensure a 280 ml cartridge size is sufficient for the planned sealing work
• Consider ventilation and curing times in the intended installation area

Usage recommendations

For best results, prepare joints by removing old sealant and degreasing surfaces. Apply at temperatures recommended by the manufacturer and allow full cure before exposing to continuous water. Use a compatible smoothing tool and avoid painting over the cured silicone unless specified as paintable.
