Product Description

Fire Retardant Treatment For Wood and Timber

Zeroflame Fire Retardant Treatment is a water based, clear solution that soaks into wood to leave the appearance of the timber virtually unchanged. Applied by brush, roller, spray, dip or vacuum method it achieves Euroclass B (BS Class 0) Fire Propagation and Spread of Flame fire protection on solid timbers. Zeroflame Fire Retardant Treatment can be used inside or out and the fire protection remains effective for the lifetime of the wood surface.

Zeroflame Fire Retardant Treatment soaks into the woods surface, without leaving a clear glaze on top like a varnish. It then dries with virtually no evidence of the wood ever been treated, allowing you to keep the woods natural beauty. Zeroflame Treatment does not require over coating however it can be over coated for decoration and/or protection if desired (care should be taken that the fire retardant properties are not compromised).

To say that Zeroflame Fire Retardant Treatment is revolutionary is an understatement, this remarkable product will protect timber substrates to British Standard Class 0 certification standard, can be used internally and externally, is not affected by moisture when dry, is non-toxic and non-allergic, the list goes on! Never before has there been such a simple product to use for the protection of timber against fire.

Directions for Use

Substrate

The substrate must be clean, dry and free from contamination; existing coats must be removed by stripping or sanding.

Application

Each square metre of wood requires 270ml (360ml in the case of Cedar) of Zeroflame Fire Retardant Treament. Application method, site conditions, absorption rate of the timber, etc. will all impact on the number of coats it takes to achieve the require coverage rate. Do not mix with other solutions, stir well before use.

Use brush, roller, spray (use appropriate mask when spraying), dip or vacuum method.

After treatment of the substrate with Zeroflame Fire Retardant Treatment, the appearance of the timber should be virtually unchanged.

Please Note: For both internal and external use it is recommended that a sample of the substrate is coated to establish both absorption properties and possible colour change, particularly when used externally without a protective finishing coat as moisture may create a change in colour.

Care must be taken to comply with the coverage rate, including allowance for wastage, as inadequate application will affect the fire protection.

Drying Times

  • Coats should be applied at intervals of 40-60 minutes.
  • Drying time is 24 hours @ 20°C.
  • Fully cured after 7 days.
  • Minimum temperature for application is 5°C.
  • Do not apply to frozen substrate.
  • Maximum fire retarding capabilities acheived after 7 days.

Please Note: Drying times are dependent upon the absorption characteristics of the substrate and drying conditons. At low temperatures and/or conditions of relative humidity, drying times will be extended.

Overcoating

Where a final decorative finish is required, substrate must be fully dry before over-coating. We advise checking the moisture content of the substrate prior to application and applying the top coat to the manufacturers instructions. A small area of the substrate should be tested for compatibility before the full, final coat if applied. Contact the Technical Department for more information prior to overcoating Zeroflame Fire Retardant Treatment.

Protection Period

Fire retardant properties will remain effective for the lifetime of the substrate.

Certification

  • BS EN 13823 & BS EN 11925-2 Single Burning Item Euroclass B-s1-d0 (s1: Smoke Production, d0: Flaming Droplets) (Equivalent to UK "Class 0" BS 476 Part 6/7)
  • NT 053 & NT 054 Accelerated weathering of fire retardant wood for fire testing.
  • Euroclass C (Equivalent to UK Class 1) for plywood.

Questions



questions Jacqui Watson on 09/06/2018
Question: 

Is this the correct product for fire protecting chestnut cladding on the external wall of my extension?

Answer: 

Zeroflame Fire Retardant Treatment achieves Euroclass B (BS Class 0) Fire Propagation and Spread of Flame fire protection on bare, solid timbers. You must ensure this level of fire protection is acceptable to your authority for the requirements of your project before use. If this is not the correct level of protection required by your authority please contact our Technical Department who will be able to provide an alternative product/system for you.

questions Dean Smith on 24/05/2018
Question: 

We are using recently felled Larch which has only been airdried is this product suitable. Kind regards Dean

Answer: 

The timber should have less than 20% moisture content. We would also recommend you do a drop test with water to see whether it can soak in. As always we would recommend you do a small test area before coating the full project to confirm suitability.

questions Howie on 19/04/2018
Question: 

Is this suitable for tanalised wood?

Answer: 

Yes, tanalising timber doesn't normally seal it so the Zeroflame Fire Retardant Treatment can still soak in. If in doubt, try a drop test with water.

questions roula on 04/04/2018
Question: 

can you please advise on fire retardant product that could be used for solid maple wood floor . product shall keep the wood aspect unchanged. kind regards, Roula

Answer: 

We don't know of a problem with maple wood but as long as the maximum density is no more than 780 kg per m3 then it should be fine. A drop test with water will also show whether Zeroflame Treatment can soak in. We recommend you try a small area first to assess if there is any colour change.

questions LENA BALESI on 06/03/2018
Question: 

All leaseholders have to have a fireproof door in a block of flats built in the 1930ies. They all have to be an exact replica of the existing doors which are hollow. Would it be possible to strip the doors and apply your fire retardent paint to bring them up to 30 mins resistance time? With many thanks Lena Balesi

Answer: 

Zeroflame Fire Retardant Treatment achieves Euroclass B Fire Propagation and Spread of Flame on solid timbers, not 30 minute protection. The products we do have to provide 30 minutes fire resistance to doors (Door Upgrade Kits) cannot be applied to hollow doors.

questions Jonathan Potts on 04/03/2018
Question: 

Can you please advise on the wood stains that are compatible with the Zeroflame Fire Retardant Treatment. I am looking for the specific manufacturer and product names that have been tested with Zeroflame.

Answer: 

Dedicated topcoats for Zeroflame Fire Retardant Treatment are being looked at but at present the advice is any waterborne stain can be used over Zeroflame Fire Retardant Treatment as long as it is compatible, non-flammable and will dry. We always recommend to try a small sample area first to ensure the stain does not react with Zeroflame Fire Retardant Treatment and will dry out.

questions paul sharpe on 06/02/2018
Question: 

Can this product be used on a boundary on featheredge cladding?

Answer: 

Zeroflame Fire Retardant Treatment can be used on internal or external bare wood. It is regularly used on cladding and achieves Euroclass B (BS Class 0) Fire Propagation and Spread of Flame fire protection on solid timbers.

questions louise killip on 02/02/2018
Question: 

hi, please can advise which paints or stains are compatible to use over timber that is coated with Zeroflame FR Treatments? Thanks

Answer: 

Waterborne paints and varnishes are recommended for overcoating Zeroflame Fire Retardant Treatment.

questions Paul shipway on 01/02/2018
Question: 

Do you have a copy of the test certificate. We are Firas approved and need to be sure all products have been tested.

Answer: 

Yes, a copy has been forwarded to your email address.

questions Dave Budworth on 29/03/2017
Question: Hi, Can Zero Flame be used on cedar cladding to achieve Building Regs requirements for non combustible materials on Dormer roof structures?
If so, does the product need to be applied to both sides of the cladding (i.e inner and outer faces)?
and would the product effect the natural weathering of cedar cladding over time if applied to outer faces?
Thanks
Answer: 

Zeroflame Fire Retardant Treatment achieves Euroclass B (BS Class 0) Fire Propagation and Spread of Flame fire protection on solid timber. You will need to refer to your authority to ensure this is the level of fire protection they are expecting you to achieve. Due to it being a Surface Spread of Flame rating usually only the sides exposed to fire would need to be treated. Finally, this product would NOT stop or affect the natural weathering process of the wood.

questions graham walsgrove on 15/03/2017
Question: Hi could you please tell me if your products have undergone third party testing and if so by whom??

It's just your product has been specified for a Building Regulation application and we need to know if it's been tested

Many thanks
Answer: 

We have sent copies of the test data to your email address.

questions Michael on 24/11/2016
Question: Would this be suitable for a fire surround/mantle? The fire Stove sides will be 100-120 mm from the upright beams. So need some kind of retardant to resist heat!
Answer: 

Zeroflame Fire Retardant Treatment would certainly increase fire resistance of the timber surrounding your fire but it can't be used as a substitute for the correct installation and required distances of your fireplace.


We have written an extensive article on Painting the Walls around a Fireplace or Multi Fuel Stove which can be found HERE.

questions roger lister on 21/07/2016
Question: will this product fireproof building felt if not any ideas would be helpful
Regards
Roger
Answer: 

No, Zeroflame Fire Retardant Treatment cannot be used on felt. Rust-Oleum Mathys Dacfill HZ has an external fire exposure roof test to BS 476: Part 3: 2004 and achieved EXT.F.AC

questions Vicky on 18/07/2016
Question: I am having 6 solid pine doors dipped back to bare wood. I need the door to be fire retardant up to 20 minutes. Is this product suitable. Thanks
Answer: 

Zeroflame Fire Retardant Treatment provides surface spread of flame protection but does not provide fire resistance for 20, 30 or 60 minutes protection so would not be suitable. The product that would be suitable is Fire Door Varnish (30min), this upgrades normal timber flat panel, raised and fielded and ledged and braced doors to 30 minute fire resistance. Each pack contains sufficient primer, intumescent varnish and topcoat (available in clear matt, satin or gloss finishes) to upgrade 4 door sides (including architrave and frame).

questions DEB on 16/07/2016
Question: Hi can zero flame be applied ontop of a impregnation fluid to a log cabin
Answer: Zeroflame Fire Retardant Treatment can be applied to pressure treated timber as long as the fluid used was water based.
questions Wayne Lovelock on 25/01/2016
Question: 

Does Zeroflame Fire Retardant Treatment need to be applied to bare wood in order for it to be effective?

Answer: 

Yes it does, it is designed for bare softwood and hardwood and relies on penetrating into the wood. It will only achieve BS Class 1 on veneer and plywood laminates due to the bonding glues hindering penetration. Zeroflame Fire Retardant Treatment also is not suitable for wood-derived particle boards or similar such as MDF and OSB due to it not being absorbent enough.

questions Jonathan cooper on 23/01/2016
Question: 

Could Zeroflame Fire Retardant Treatment be used on top of painted, unsealed timber or would the wood need to be sanded back first? Second, could you paint over the top once applied rather than applying stain/varnish?

Answer: 

Zeroflame Fire Retardant Treatment is a penetrative fluid that must be applied to porous, bare timber in order for it to soak in to the wood to be effective. It is not suitable for application over any previous coatings, these must be removed by stripping or sanding prior to application. Once Zeroflame Fire Retardant Treatment has been applied and allowed to sufficiently dry (usually around 7 days), you may apply certain stains, varnishes and paints for decoration purposes (contact our Technical Department for details of coatings that are suitable).

questions Rob Smith on 08/01/2016
Question: 

Is Zeroflame Fire Retardant Treatment suitable for use on Bamboo? This is for use in a hotel.

Answer: 

It isn't, but we do have a clear varnish system that is. Please contact our Technical Department on 0113 2455450 for details.

questions Robert Jakes on 03/06/2015
Question: 

Hi, we've just made some large flowers (out of willow withies, lantern tissue and pva) for decor to go inside a marquee at Glastonbury, can you tell us if Zeroflame Fire Retardant Treatment would be suitable to coat them with as a fire retardant?

Answer: 

No, the Zeroflame Fire Retardant Treatment would not be suitable but our 1012 Fire Retardant Solution would be.
