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).

The Basics

What you really need to know...

  • Each 5L will treat 18.5m² and 20L 74m² (If applying to Cedar woods coverage reduces to 13.5m² per 5L and 54m² per 20L)
  • Protects internal & external timber to Euroclass B (BS Class 0)
  • Provides an almost invisible fire retardant treatment to the wood
  • Must be applied to bare timber ONLY.
  • Can be applied with a brush, roller, spray, dip or vacuum treatment.

Application Areas

Zeroflame Fire Retardant Treatment is a fire retardant system for the fire protection of hardwoods, softwoods and other cellulose based substrates.

Zeroflame Fire Retardant Treatment treated timber must only be used above the Damp Proof Course level and/or above ground contact. Trials should be carried out on decorative timber species to check any shade changes prior to the full application of the Treatment.

Un-Matched Performance

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.

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.

Limitations

  • Final Finish - Natural. Can be overcoated with certain stains, varnishes and paints. (contact Technical for details of coatings which are suitable).
  • Zeroflame Fire Retardant Treatment achieves Class 1 only, on veneer and plywood laminates, due to the bonding glues resisting penetration. If Class 0 is required on such materials, Zeroflame Fire Retardant Paint or 1002 Fire Retardant Varnish is recommended.
  • Discolouration may occur on some types of timber or on heavily knotted wood. If this is a concern it is recommended that a sample area is completed before application to the whole project. Alternatively, application of a compatible varnish or stain may help overcome this phenomenon if it is unacceptable.
  • Zeroflame Fire Retardant Treatment is not suitable for wood-derived particle board or similar as it cannot penetrate. Again, Zeroflame Fire Retardant Paint or 1002 Fire Retardant Varnish is recommended.

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

Dave Budworth from Bristol (Uk) - 29/03/17

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.

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 testedMany thanks

graham walsgrove from winchester (england) - 15/03/17

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

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!

Michael from Brighton and Hove (England) - 24/11/16

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.

will this product fireproof building felt if not any ideas would be helpful Regards Roger

roger lister from cambridge (england) - 21/07/16

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

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

Vicky from Eastbourne (UK) - 18/07/16

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).

Hi can zero flame be applied ontop of a impregnation fluid to a log cabin

DEB from BRISTOL (UK) - 16/07/16

Zeroflame Fire Retardant Treatment can be applied to pressure treated timber as long as the fluid used was water based.

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

Wayne Lovelock from Coventry (England ) - 25/01/16

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.

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?

Jonathan cooper from Cheltenham (England) - 23/01/16

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).

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

Rob Smith from North Yorkshire (North Yorkshire) - 08/01/16

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

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?

Robert Jakes from Pembroke (UK) - 03/06/15

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