OTTOSEAL® S 70 - special silicone for marble and natural stone without edge zone staining
OTTOSEAL® S 70 is the premium silicone for demanding grouting in natural stone - indoors and outdoors. It was specially developed to prevent discolouration and staining of the edges of sensitive materials such as marble, granite or sandstone. This preserves the natural beauty of the stone in the long term.
Whether in bathrooms, on terraces, on façades or around the pool: OTTOSEAL® S 70 impresses with its excellent adhesion, weather and UV resistance as well as its fungicidal finish - for clean, mould-free joints for many years to come. The silicone is available in numerous colours, including matt and textured shades that perfectly match natural stone surfaces. You can of course also find more silicone caulk and decorators caulk in our shop.
OTTOSEAL® S 70 is also tested and approved for use in food-related areas (e.g. kitchen worktops made of natural stone) - a real all-rounder for craftsmanship and design.
You can remove old acrylic or silicone quickly and easily with our joint cutter.
