Zeroflame Fire Retardant Paint is a matt white, single-pack waterborne coating for wood, and other wood derivatives that achieves Class 1 and Class 0.
Zeroflame Fire Retardant Paint is a waterborne fire protection coating for interior use. This coating has been successfully tested on a variety of timber substrates to BS 476, Classes 0 and 1, which achieves B-s2, d0 classification. 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.
Zeroflame Fire Retardant Paint can be applied to reduce 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. 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.

Each tin has a certificate application form on the back of the label. To receive a 'Certificate of Supply' for your purchase, after application of the product, simply complete the form on the label and send to the stated address and a certificate will be returned to you within 7-10 working days.
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. Building Regulations classify C-s3, d2 as being equivalent to Class 1, and B-s3, d2 equivalent to Class 0. Zeroflame Fire Retardant Paint exceeds both these classifications on timber surfaces when applied according to the manufacturer's recommendations.
| Appearance When Dry: | Matt White |
| Mass Density: | Approx. 1.29 g/cm³ |
| Solids by Weight: | Approx. 65% (according to EN ISO 3251) |
| 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.
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 higher relative humidity may extend drying times. Allow 48 hours before overcoating.
Immediately after use, clean the equipment with water.

Question: I have a wooden store cupboard situated to the side of a staircase which is designated as a potential escape route in the event of fire. Would this product give me 30 minute protection as specified by our local fire service if painted inside and out side the cupboard? |
Answer: Zeroflame Fire Retardant Paint achieves BS Class 1/0 Surface Spread of Flame protection, if 30 minute fire resistance is required we would instead recommend Thermoguard Timbercoat 30 & 60 Minute System. | |
| Francis on 13/02/2019 |
Question: I have a loft space which is fitted out with 50mm tongue and groove pine cladding. It’s not painted, but I would like to fire proof it then paint in my chosen colour. The Zero Flame paint seems to fit what I need. Can I ask your advice before purchasing. Yours Francis |
Answer: Zeroflame Fire Retardant Paint achieves Class 1 and Class 0 on timber substrates so if this level of protection is what you require then it would be suitable. We do suggest priming pine with something like Zinsser B-I-N first to prevent bleeding/staining through of knots, etc. | |
| Becky on 19/12/2018 |
Question: Is the paint very thick? I.e. if applied over a woodgrain would the grain still be visible beneath the layer of zeroflame and a top coat of coloured emulsion? |
Answer: The total DFT (Dry Film Thickness) of Zeroflame Fire Retardant Paint after the required 2 coats should be 180 microns. To give some perspective to this, a normal single coat of emulsion would usually be in the region of 20-30 microns DFT on average. | |
| Said Attia on 27/10/2018 |
Question: I want to know if this product can be used in concert wall or cement surface |
Answer: We're assuming you mean concrete wall, so instead to achieve BS Class 1/0 and EN Class B surface spread of flame protection we would recommend Thermoguard Wallcoat BS Class 1/0 & EN Class B System. | |
| Colin on 23/10/2018 |
Question: Hi, My fire officer wants confirmation that an FR paint like Zeroflame when applied to FR Euroclass B MDF 18mm, will maintain the substrates Euroclass B rating. Can you confirm this will be the case is i use the 2 coat on 1 coat Zinsser mentioned in your 04/09/19 question answer to Brian? |
Answer: In the previous answered question you are referring to we have assumed that the customer wants to upgrade normal, non-fire rated MDF to EN Class B-s2, d0. In your instance, if your MDF already has the level of fire protection you require and you simply wish to decorate and maintain the level of fire protection we would instead recommend Thermoguard Wallcoat Smoke & Flame Retardant Topcoat. This product is available in a Matt or Eggshell finish in nearly all RAL and BS colours and can be applied directly to the prepared MDF without the need of a primer and does not require anything to be applied afterwards. After use of the product certification can be applied for by completing a short online application HERE. | |

Question: How many coats on bare mdf for zero flame paints |
Answer: 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. | |
| graham jones on 17/07/2018 |
Question: 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. |
Answer: 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+. | |
| Craig on 10/07/2018 |
Question: Do you sell a 1 litre tub? |
Answer: No, 5lt is the only pack size available in this product. | |
| David on 23/06/2018 |
Question: 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? |
Answer: No, Zeroflame Fire Retardant Paint can be applied directly to bare timber. | |
| paul on 05/06/2018 |
Question: 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 |
Answer: 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. | |
| Elizabeth Fisher on 02/05/2018 |
Question: 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. |
Answer: 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. | |
| Paula on 20/03/2018 |
Question: 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 |
Answer: 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. | |
| Paul on 10/10/2017 |
Question: Is this product suitable for mdf ? |
Answer: 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. | |
| sam on 11/05/2017 |
Question: can this product be used on glossed painted surfaces? |
Answer: 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. | |
| Donovan Cook on 07/12/2015 |
Question: 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? |
Answer: 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. | |
| arwel on 13/10/2015 |
Question: Is Zeroflame Fire Retardant Paint half hour fire resistant? |
Answer: 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. | |
