The nine most popular colours of Ottoseal S 70 natural stone silicone are now also available in a matt finish.

Ottoseal S 70 for flexible joints in natural stone projects is available from stock in 46 colours, including ‘structural’ colours with stone-like surfaces and, now, nine popular matt finishes.

The subtle palette of Ottoseal ranges from Carrara white to graduated beige and grey for limestones and granites, as well as bold dark green, anthracite and black for jointing Verde Aosta, Tauerngrün, slate and the near-blacks of Nero Africa, Nero Assoluto and Star Galaxy.

Otto’s neutral curing silicone sealant is specifically produced for working with natural stone and causes no migratory staining.

The matt versions of Ottoseal S 70 have also been tested and certified as LEED-compliant.

Otto introduced the matt finish to keep up with the current trend for slip-resitant matt surfaces to classic floor coverings in natural stones.
