Product Description

Zeroflame Fire Retardant Paint will achieve Class 1 and Class 0 on timber surfaces, and will maintain Class 1 and Class 0 on non-combustible surfaces such as plaster walls. It is suitable for use over sound existing coatings and can be over-coated with standard latex paints where a decorative finish is required. This single-pack, waterborne product is extremely simple to use.

For internal use only, Zeroflame Fire Retardant Paint has been successfully tested on a variety of timber substrates to BS 476, Classes 0 and 1, which achieves B-s2, d0 Classification.

Once applied, this coating reduces the ignitability of soft and hard wood and other wood derivatives, i.e. plywood, chipboard, fibre insulation board, hard board, and 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.

Zeroflame Fire Retardant Paint has been tested to EN 13501-1:2007 on timber and composite wood substrates, European classes B-s1, d" and B-s2, d0 being obtained.

VOC Content :Max. 0g/litre (2010 EU limit: 140g/litre)


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

  • 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.

How many coats on bare mdf for zero flame paints


We recommend Zinsser Bulls Eye 1-2-3 or similar as a primer on MDF before applying 2 coats of Zeroflame Fire Retardant Paint undiluted at 7.4m² per litre/per coat.

questions graham jones on 17/07/2018

I have a circular hollow steel column 2.5m high. Building control insist I paint it with a paint to class 0 fire rating. Is there a paint you can recommend.


Class O would be an unusual request for steel, we would suggest checking with your building control as usually they would instead require 30min, 60min, etc.

If this turns out to be the case then we would recommend Zeroflame Aquasteel WB+.

questions Craig on 10/07/2018

Do you sell a 1 litre tub?


No, 5lt is the only pack size available in this product.

questions David on 23/06/2018

I want to use Zeroflame on a new internal timber roof. I plan to use Zinsser BIN for the wood knots. Does the rest of the timber need to be primed or can Zeroflame be applied directly to the bare wood?


No, Zeroflame Fire Retardant Paint can be applied directly to bare timber.

questions paul on 05/06/2018

i need a clear fire resistant paint for my decking its bare wood at the moment which do you recomend and can i put a wood stain over it thanks


Assuming Euroclass B (BS Class 0) Fire Propagation and Spread of Flame fire protection is required, for decking we would recommend Zeroflame Fire Retardant Treatment be applied to the bare timber. Waterborne stains or varnishes can be used over Zeroflame Fire Retardant Treatment as long as they are compatible, non-flammable and will dry. We always recommend the timber is allowed sufficient time to dry after application and to try a small sample area first to ensure the stain does not react with the Zeroflame Fire Retardant Treatment and will dry out.

questions Elizabeth Fisher on 02/05/2018

Hi, I'd like to use Zeroflame fire retardant paint so I can apply a decorative paint colour finish to some interior timber cladding. Will this meet building regs? Can you issue a certificate of supply for Zeroflame paints like you do for Thermoguard Timbercoat? Many thanks.


Zeroflame Fire Retardant Paint achieves Class 1 and Class 0 on interior timber surfaces, if this is the level of protection you require then it can be overcoated with waterborne latex paints, applied at a total dry film thickness not exceeding 35 microns. After use, certification can be applied for by completing and returning the Certificate Application Form included on the back of the label on the tin.

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.
