Zeroflame Wood-S 12.5kg Intumescent Fire Retardant Coating for Internal Timber and Wood Surfaces

Zeroflame Wood-S 12.5kg Intumescent Fire Retardant Coating for Internal Timber and Wood Surfaces

Zeroflame Wood-S is a high-performance, waterborne intumescent coating designed to slow the spread of fire on internal wood and wood-based surfaces. Independently tested to European Standard EN 13501-1, it achieves Class B-s1, d0, helping you meet fire safety regulations in both commercial and domestic interiors.

Applied directly to wood and suitable substrates, it dries to a matt white finish, which can be left as is or overcoated with Zeroflame Topcoat W for added protection or decorative flexibility.

Whether you're treating timber cladding, ceilings, or panelling, Zeroflame Wood-S offers professional-grade fire resistance without compromising design.
