👷 📋 The Master Tiler's Verdict

"When you are working on commercial sites, apartment blocks, or around sensitive electrical and HVAC installations, you don't mess around with standard sealants. Building control will check your fire seals. The S 94 is the industry standard for compliance. Because it's a neutral cure, it won't corrode bare metals or pipework, and the B1 rating gives you total peace of mind on sign-off."

Pro Tip: To ensure compliance with passive fire protection regulations, always verify that the joint depth and backing material meet the specific fire-rating requirements of your substrate before applying the sealant.

Why the Professionals Choose OTTOSEAL S 94

• B1 Fire Retardant: Complies with the stringent DIN 4102 building material class B1, essential for joints requiring increased passive fire protection.
