Extremely reliable: The grout has a very good adhesion on smooth surfaces, which prevents moisture damage to the surface, for example, in sinks, showers and baths, and promises a long-lasting grouting.
Easy to process and smoothen: The high-quality formula of the sealant allows quick and easy processing and thus a rapid progress in grouting and sealing – whether moving or renovating, you are prepared for all sealing work.

Areas of application: The silicone reliably seals joints, whether they are corner joints, movement- and connection joints in sanitary facilities, expansion joints between tiles, or window and glass sealing.
