OTTOSEAL S 100 Sanitary silicone sand grey 300 ml – mold resistant & permanently elastic

OTTOSEAL S 100 sanitary silicone is a high-quality sealant for joints exposed to constant moisture in bathrooms, showers, and kitchens. From the very first application, it becomes clear that this product was designed for demanding sealing work. It reliably protects against penetrating water, creates clean transitions, and helps joints remain both functional and visually appealing over the long term. Especially in areas with high humidity, dependable sealing is essential for hygiene and value retention.
This one-component, acetoxy-curing silicone offers an excellent balance of adhesion, elasticity, and easy handling. It bonds perfectly to non-porous substrates such as glass, ceramics, enamel, acrylic, and aluminum. That makes it ideal for connection and expansion joints where different materials meet and movement must be absorbed.

Properties and benefits at a glance

The formulation is tailored to the typical requirements of sanitary environments:

• mold-resistant thanks to fungicidal protection
• permanently elastic for durable joints
• excellent adhesion to smooth surfaces
• resistant to UV, aging, and weathering
• easy to tool for a uniform finish
• suitable for indoor and outdoor use

These features make OTTOSEAL S 100 sanitary silicone a strong choice for new installations as well as for renovation of existing joints. The result is a tight, resilient seal with a neat appearance.
In addition to technical performance, application comfort is a major advantage. The silicone is dispensed evenly from the cartridge and offers a short skin formation time, allowing precise work. After tooling, the surface becomes smooth, enabling water to bead off effectively.

Application and processing

Before application, the substrate must be clean, dry, and free from grease or dust. Old sealant residues should be completely removed to ensure optimal adhesion. Insert the cartridge into a suitable caulking gun, apply the material evenly into the joint, and smooth it within the open time using an appropriate tooling agent.
Once cured, OTTOSEAL S 100 sanitary silicone demonstrates its full performance. The joint remains flexible and withstands even significant temperature fluctuations. Continuous exposure to moisture does not compromise the seal, which stays stable and visually attractive.
Because of its high resistance, the product is suitable not only for private bathrooms but also for heavily used sanitary facilities. Reduced maintenance effort and long service life make OTTOSEAL S 100 sanitary silicone an economical solution with professional standards. Anyone looking for reliable sealing, a clean finish, and lasting protection will make a well-considered decision with OTTOSEAL S 100 sanitary silicone.
