👷 📋 The Master Tiler's Verdict

"Stop using standard silicone on high-end stone. I’ve seen too many beautiful stone installations ruined by staining from cheap silicone. The OTTOSEAL® S 70 is my go-to because it is specifically engineered for natural stone (marble, granite, quartzite)."

Pro Tip: It’s neutral-curing, meaning it won't corrode your metal fittings, and the 'no-staining' guarantee is your insurance policy for premium finishes.

Why the Professionals Choose OTTOSEAL S 70

No Migratory Staining: Guaranteed not to stain natural stones like marble, sandstone, quartzite, granite, gneiss, and porphyry in interior and exterior areas.
Excellent Workability: Extremely long-lasting joint that is resistant to mould, ideal for sealing expansion and connection joints in floors, walls, and facades.
Versatile Application: Perfect for bathroom areas, swimming pools, external mirror sealing, and movement-compensating bonding of natural stone on metal (e.g., stairs on a metal construction).
Highly Durable: Features excellent weathering, ageing, and UV-resistance.
