Product details

The low odour natural stone silicone OTTOSEAL® S 80 doesn't cause any marginal staining when sealing and jointing marble and different types of natural stone, such as sandstone, quartzite, granite, gneiss or prophyry. Thanks to the very good weathering, ageing and UV-resistance, as well as being equipped with fungicide, OTTOSEAL® S 80 ensures long-lasting joints, both indoors and outdoors. Attention: To smooth, we recommend the special OTTO marble silicone smoothing agent.
