Application and maintenance tips
To ensure proper adhesion, surfaces must be thoroughly cleaned before sealing. Bonding surfaces must be dry, clean and structurally sound. For smooth materials like glass or stainless steel, a suitable primer may be required. After application, the joint can be shaped immediately using a finishing agent or appropriate tool.
Once cured, joints can be cleaned easily with a damp cloth, keeping them hygienic and visually appealing over time.

Frequently Asked Questions (FAQ) about OTTOSEAL® S 100 Silicone sanitary grey glossy (C18)
How does the colour "sanitary grey glossy (C18)" differ from other greys?
Sanitary grey (C18) is a soft, light grey tone with a slightly warm undertone and a glossy finish. Compared to, for example, Manhattan (C43) or Cement grey (C706), it appears softer and more neutral – making it ideal for white or grey sanitary fittings where the joint should be discreet.
Is this silicone suitable for direct water exposure?
Yes, OTTOSEAL® S 100 in sanitary grey is specifically designed for continuous exposure to moisture in areas like shower enclosures or bath edges. Its fungicidal formulation reliably protects against mould growth.
Can this silicone be used on natural stone?
No, OTTOSEAL® S 100 is not suitable for sensitive natural stones such as marble or slate, as it may cause edge staining. OTTOSEAL® S 70 or S 80 are the recommended alternatives for natural stone applications.
How should I apply this product at low temperatures?
The silicone can be applied from +5 °C. In cooler conditions, the cartridge should be warmed to room temperature to ensure smooth extrusion and clean joint formation. After application, the joint can be shaped as usual.
How long before the joint can be exposed to stress or moisture?
The silicone becomes skin-dry after approx. 10 minutes and cures 2–3 mm deep within 24 hours under standard conditions (23 °C, 50% rH). The joint should not be mechanically or water-loaded until it has fully cured.
Is colour C18 suitable for concrete-look tiles?
Yes, sanitary grey glossy (C18) is an excellent match for concrete or cement-look tiles. Its soft and neutral hue provides smooth transitions and subtly enhances the texture of the tile surface.
How can I ensure long-term mould resistance in the joint?
Besides using fungicide-equipped silicone, regular cleaning and proper ventilation are essential. For example, after showering, removing water residues and airing the room will help keep the joint clean and hygienic for longer.
