Zeroflame Fire Retardant Treatment for timber 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 with waterborne, non-flammable paints for decoration and/or protection if desired (care should be taken that the fire retardant properties are not compromised).
Please Note: Timber must be a minimum of 12mm thick for the treatment to be effective.
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.

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.

Directions for Use
The substrate must be clean, dry and free from contamination; existing coats must be removed by stripping or sanding.
Each square metre of wood requires 250ml 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.
- 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.
Where a final decorative finish is required, a water-borne, non-flammable varnish or wood stain maybe used. The 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.
Fire retardant properties will remain effective for the lifetime of the substrate.

- BS EN 13823 & BS EN 11925-2 Single Burning Item Euroclass B-s2-d0 (s2: 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.
- Final Finish - Natural.
- 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 Thermoguard Fire Varnish BS Class 1/0 & EN Class B System 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 Thermoguard Fire Varnish BS Class 1/0 & EN Class B System is recommended instead.
- Please Note: Timber must be a minimum of 12mm thick for the treatment to be effective
