Zeroflame Fire Retardant Paint can be applied to reduces the ignitability of soft and hard wood and other wood derivatives, i.e. plywood, chipboard, fibre insulation board, hard board, also on veneering ≥ 12mm thickness. Zeroflame Fire Retardant Paint insulates against heat, checks fire, prevents propagation of fire and diminishes flue-gas density and flue-gas temperature. For interior use only, not suitable for surfaces exposed to mechanical stress.

Stir Zeroflame Fire Retardant Paint thoroughly until free of lumps. Substrates must be dry (moisture content must not exceed 15%), free from dust, wax, grease, dirt, resin, etc. Existing coatings with poor adhesion must be completely removed. Coatings containing lime, chalk or lithopone should be removed.


Airless Spray

  • Zeroflame Fire Retardant Paint should be applied undiluted
  • Airless spray equipment with pressure ratio 30:1
  • Hose diameter not below 3/8"
  • Whipline 1.5-2m. NW6 may be used
  • Recommended tip size 0.34-0.66mm or 0.17-0.027"
  • Hoses must be used only for water based coatings


  • Zeroflame Fire Retardant Paint should be applied in supplied viscosity


Object temperature not below +10°C, to max. +40°C, relative humidity max. 70%.

Application temperature shall be at least ≥ 3°C above dew point. In case relative humidity exceeds 80%, special measures must be taken to prevent condensation forming when applying. If the moisture content of the substrate exceeds 15%, the coating is unlikely to dry and blooming may occur. Moisture content should be at, or near that anticipated when in use.


At approx. 20°C temperature and 65% relative humidity approx. 6 hours. Lower temperatures and higer relative humidity may extend drying times. Allow 48 hours before overcoating.


Immediately after use, clean the equipment with water.

questions Paula on 20/03/2018

Hi, When using a decorative paint over the top of Zeroflame you mention using a 'latex' paint. Do you mean any water based paint / emulsion or something more specific? Many thanks, Paula


The data sheet for Zeroflame Fire Retardant Paint states 'When overcoating use only waterborne latex paints, applied at a total dry film thickness not exceeding 35 microns.' This is because it was a latex based paint that was used in the fire test. Zinsser Perma-White Interior is an example of a latex based paint. However, in some countries what we call an acrylic is called a latex. Zeroflame recommend a waterborne paint, preferably latex based is used.

questions Paul on 10/10/2017
Question: Is this product suitable for mdf ?

Zeroflame Fire Retardant Paint can be used on MDF to achieve Class 0 spread of flame. It is recommended that Zinsser Bulls Eye 1-2-3 is used as a primer to ensure good adhesion before applying the Zeroflame Fire Retardant Paint.

questions sam on 11/05/2017
Question: can this product be used on glossed painted surfaces?

Yes as long as the surface to be painted is first thoroughly abraded to provide a suitable key for the Zeroflame Fire Retardant Paint to adhere to.

questions Donovan Cook on 07/12/2015

Once applied, what is the life span of Zeroflame Fire Retardant Paint before needing to be applied again to ensure BS 476 parts 6 and 7 are maintained?


The fire protection provided by Zeroflame Fire Retardant Paint remains effective indefinitely as long as the coating is not damaged. Any areas of damage, wear, etc. can be remedied by the re-application of Zeroflame Fire Retardant Paint to the affected area to restore protection.

questions arwel on 13/10/2015

Is Zeroflame Fire Retardant Paint half hour fire resistant?


No, Zeroflame Fire Retardant Paint upgrades timber surfaces to European Standard EN13501-1:2007, achieving B-s1d0 Classification which is a superior equivalent to our British Standard 476 Classes 0 & 1. If you require 30 or 60min protection please contact our Technical Department on 0113 2455450 for suitable systems.
