Key applications: OTTO S70 natural stone silicone sealant for sealing joints between worktops and upstands, or bonding worktops to carcasses. Suitable for interior and exterior use where a stone‑safe, non‑staining silicone is required.

Suitable for use on the following stone types: Natural stone, granite, marble, quartz and engineered stone.

Instructions for use: Proper application of silicone sealant is essential to ensure durability and performance. We recommend maintaining 5–6mm joints for flexibility, using a 45° angle smoother to achieve an even finish and reduce the risk of mould build‑up, and widening the nozzle to minimise air pressure and apply a consistent bead. Incorrect application may compromise results. For further guidance or support, contact us or arrange training at our Innovation Hub. Download the safety data sheet.
