Bollom Intulac™ Ultra Top Coat is a clear, protective varnish designed to be applied over Intulac Ultra Intumescent Base Coat, completing a high-performance fire protection system for interior timber.
Forming part of a 3-coat system, this topcoat seals and protects the intumescent layer beneath while enhancing the natural look of the wood. Available in matt and satin finishes, it provides a clean, decorative appearance without compromising fire performance.
When used correctly, the system achieves a Class B-s1, d0 fire rating, significantly reducing flame spread and heat release - making it ideal for public buildings, commercial interiors and communal areas.
Designed for ease of application, this single-pack varnish can be applied by brush, roller or spray, making it suitable for both site work and controlled environments.
