Bollom Intulac Ultra Basecoat

Bollom Intulac Ultra Basecoat is a clear high performance fire protection varnish coating for interior wood surfaces. Use with Bollom Intulac Ultra Topcoat Satin or Matt Finish to complete the protective coating system to deliver Class 0 and fire performance.

The Bollom Intulac Ultra Varnish system provides a high performance fire protection coating system for interior wood surfaces. It comprises a clear, intumescent base coat – designed to form a protective carbon char in the event of fire, delaying the inflammation of the wood – and a clear, protective top coat (available in Matt and Satin finishes).

It is not suitable for surfaces exposed to mechanical stress, such as floors, doors, stairs etc.

Recommended Uses

  • Communal areas
  • Softwood
  • Hardwood
  • Plywood 
  • Chipboard
  • Fibre insulation board
  • Hardboard
  • Veneering less than 12mm thick

Intulac Ultra Base Coat 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. It also insulates against heat, checks fire, prevents propagation of fire and diminishes flue-gas density and flue-gas temperature.

NB: Bollom Intulac Ultra Basecoat must be overcoated with Bollom Intulac Ultra Topcoat after 48 hours and not more than 4 days. It is important to speak to our Technical Department and refer to the product data sheet prior to using this product to ensure the correct specification has been chosen for your surface.

Features and Benefits

  • Can be applied over existing varnish - Maximum of four, single, well-adhered coats
  • Simple 3 coat system to achieve Class 0
  • Single pack products so no mixing required
  • Protects and highlights the natural beauty of the wood - ideal for timber in communal areas.
  • For interior use only. Not suitable for surfaces exposed to mechanical stress, such as floors, doors, stairs etc.

Coverage and Application

Bollom Intulac Ultra Basecoat should be applied undiluted by brush, roller or spray. Surfaces to be painted must be primed with Bollom Intulac™ Ultra Intumescent Base Coat
and dry, free from dust, oil, wax, grease and release agents. Apply two coats of Bollom Intulac Ultra Basecoat to a coverage rate of 5m² per litre, per coat (this means a 5lt tin will cover a total of 12.5m² after the two coats). The Intulac Ultra system requires the application of both the Intumescent Base Coat and Protective Top Coat. The Intulac Ultra Basecoat must be left a minimum of 48 hours and max of 4 days prior to applying the Intulac Ultra Topcoat. Apply 1 coat of Bollom Intulac Ultra Topcoat at 25m² per litre.

Dear seller Can you please advise what I will need to fire protect my bare wood ceilings ( tulip wood ) . I would like to achieve a satin finish that will not detract friom the beauty of the wood . My indoor house vaulted ceilings project is approximately 80 square meters . My mobile number is 07904571744 . I would appreciate your best price including vat and delivery in addition to your recommendations . Thank you


Assuming the level of fire protection required is Euroclass B (BS Class 0), then we would recommend Zeroflame Fire Retardant Treatment. 80m² would require 22 litres of the product.
