The premium natural stone silicone OTTOSEAL® S 70 is perfect for all marble and natural stones indoors and outdoors and does not cause any marginal staining on natural stones. OTTOSEAL® S 70 is available in a large number of different colour shades. As a special feature here, matte colour tones and “structure” colours with a surface that is similar to stone are also available. The very good weathering, ageing and UV-resistance as well as the resistance to mould infestation ensure a durable and visually appealing overall look. Thanks to the ISEGA clearance certificate, OTTOSEAL® S 70 has been tested and approved for use in the food-related sector and is therefore perfect for these applications. Attention: To smooth, we recommend the special OTTO natural stone smoothing agent.
