This silicone is particularly well-suited for bathrooms and showers, especially for sealing expansion and joint areas in moisture-prone areas such as showers, bathtubs, and WC rooms. It is also perfect for use in kitchens and around washbasins, providing reliable sealing around sinks, countertops, and washbasins. Additionally, it is ideal for sealing glass and tile joints, offering a dependable solution for joints between glass, tiles, ceramics, and acrylic baths. It also reliably seals window connections and glass blocks, offering durable and seamless solutions for sealing joints in glass blocks, window frames, or profile glass. With its matte finish, the silicone offers long-lasting and subtle sealing solutions that are perfect for modern construction concepts and contemporary design projects.
Before application, ensure that the substrate is clean, dry, and sound. If necessary, use OTTO Cleaner T to thoroughly clean the surface. To maintain the matte appearance of the silicone, it should only be smoothed once using a smoothing tool. Avoid using any smoothing agents that may cause a glossy finish. Pay attention to material compatibility, especially with bitumen-containing or plasticiser-releasing materials, and ensure that materials are tested for compatibility beforehand. When removing old sealants, they should be completely removed before starting the re-jointing process. For long-term mould prevention, it is recommended to treat the joint with an anti-mould spray if necessary.
