OTTOSEAL® S 100 is known for its excellent weather resistance, UV stability, and ageing resistance, making it suitable for both indoor and outdoor use. Its fungicidal and bacteriostatic formulation prevents mould and bacterial growth, ensuring a hygienic and low-maintenance seal. With Item No. 13102, tilers, stoneworkers, and professional tradespeople get a reliable, efficient, and long-lasting sealing solution.
Advantages for Tilers & Craftsmen
The excellent workability of the silicone makes it particularly easy to use. Its superb smoothing and modelling properties allow for precise and clean joints, which significantly eases the work for tilers and craftsmen.
The matt finish provides a modern, elegant design with its silver-grey, matte appearance. This neutral look fits perfectly into various room designs and is particularly beneficial in modern bathrooms or kitchens.
Thanks to its high resistance to UV radiation, weather, and ageing, the silicone is ideal for outdoor use. Even after prolonged exposure to weather influences, it maintains its shape and function, making it exceptionally durable and reliable.
The silicone is fungicidal and bacteriostatic, ensuring a hygienic seal. This prevents the growth of mould and bacteria, contributing to a healthy indoor climate.
The excellent adhesion to ceramic surfaces such as tiles, glass, and ceramics ensures a permanent and reliable seal. These properties make the silicone particularly suitable for demanding applications.
Finally, the product has been tested according to the relevant EN 15651 standards (Parts 1–4) and meets the stringent criteria of EMICODE® EC1 Plus (very low emissions) as well as VOC Class A+. This guarantees a tested quality that is important for both professional craftsmen and end users.
Typical Areas of Application
In the sanitary sector, the silicone is ideal for expansion and joint seals in bathrooms, showers, toilets, and washbasins. Its high resistance and hygienic properties make it an excellent choice for these applications.
In the kitchen area, it is commonly used for sealing around washbasins, sinks, and cooktops. Here, it also ensures a clean and reliable seal, which is both aesthetically pleasing and functional.
For joints in glass blocks, the silicone is the perfect solution. It provides a discreet, yet durable seal for these specific applications.
It is also suitable for glass and tile sealing. It is ideal for sealing between glass and ceramics, as well as for sealing acrylic baths.
Practical Application Tips
To ensure optimal adhesion, the surfaces must be clean, dry, and grease-free before application. For non-porous surfaces, we recommend a thorough cleaning, while porous substrates should be cleaned mechanically.
For the best results when smoothing matte coloured joints, the smoothing tool should be used only once. Repeated smoothing can affect the matte effect, so a single application of the tool provides the best outcome.
Before applying to plastics such as PVC or rigid PVC, it is advisable to test the compatibility of the silicone. This ensures that no negative reactions occur.
For joint care, when renovating old, mould-infested joints, the old material must be completely removed. It is also recommended to treat the joint with a suitable anti-mould spray to prevent reoccurrence of mould.

FAQ – Frequently Asked Questions about OTTOSEAL® S 100 matt silver grey (C8678)
Is OTTOSEAL® S 100 suitable for natural stone?
No, due to its acetate-curing system, OTTOSEAL® S 100 is not recommended for use on natural stone, as it may cause edge discolouration. For natural stone applications, always use a silicone specifically designed for that purpose.
