Bollom Intulac Ultra Base Coat Intumescent Fire Paint for Timber

Bollom Intulac Ultra Base Coat is a clear, water-based intumescent fire protection coating designed for interior timber surfaces, forming a protective carbon char in the event of fire to delay ignition.

As part of the Bollom Intulac Ultra system, this base coat works by insulating against heat, inhibiting fire spread, and reducing flue-gas density and temperature. It must be overcoated with Intulac Ultra Top Coat (available in Matt or Satin finish) no earlier than 48 hours and no later than 4 days after application.

Suitable for both softwood and hardwood, as well as timber derivatives including plywood, chipboard, fibre insulation board, hardboard, and veneering up to 12mm thick. The simple three-coat system — base coat plus top coat — is designed to achieve Class 0 fire performance, making it suitable for use on interior joinery in commercial and residential environments where fire-rated finishes are required.

Supplied in a 5 litre container, the product is single pack with no mixing required and can be applied over existing varnish where the surface is sound and well-adhered.
