Overview
The Bollom Intulac Ultra Intumescent Basecoat system provides a high performance fire protection coating system for interior wood surfaces. It comprises a clear, transparent, water-based intumescent base coat designed to form a protective carbon char in the event of fire, delaying the inflammation of the wood and a clear, transparent, solvent-based protective Bollom Intulac Ultra Topcoat.
The basecoat is designed to form a protective carbon char in the event of fire, delaying the inflammation of the wood. It reduces ignitability of soft and hard wood and other wood derivatives I.e. plywood, chipboard, fibre insulation board, hard board and also on veneering (a minimum of 12mm thick). It also insulates against heat, checks fire, prevents propagation of fire and diminishes flue-gas density and flue-gas temperature.
Please Note: Not suitable for surfaces exposed to mechanical stress, such as floors, doors stairs etc.
Preparation
Preparation
Back
Surface must be dry, free from dust, oil, wax, grease, release agents, etc. Wood substrates with wetting difficulties should be roughened thoroughly with abrasive paper. The moisture content of the timber should be below 15%. For particularly resinous or knotty timber apply 1 coat of Zinsser Sealcoat. Application over a maximum of four, well adhered, single coats of existing varnish is possible, sand lightly before applying Bollom Intulac Ultra Intumescent Base Coat.
