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, or immersion it achieves Euroclass B s2 d0 (replaces UK Classes ‘0’ and ‘1’ BS 476 Part 6/7*) on solid timbers. Zeroflame Fire Retardant Treatment can be used inside or out and the fire retardant properties will remain active for the lifetime of the substrate.
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 stains, varnishes and 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 in commercial and domestic environments, can be used internally and externally, classifies solid wood as having little or no contribution to fire, is non-hazardous, non-corrosive and virtually odour free, 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
Check the surface is absorbent and has not been previously sealed by other coatings. The substrate must be absorbent. It is possible to apply to previously painted or varnished wood if removed completely by sanding back to the original surface.
Each square metre of wood requires 250ml of Zeroflame Fire Retardant Treatment. 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 as supplied. Do not dilute.
Test on a small area first to ensure finish is acceptable.
Ambient temperature should be above 10°C.
Moisture content of wood should be below 15%.
The use of eyewear, gloves and mask is good practice and recommended.
Clean tools and overspill with absorbent paper and water.
Apply by brush, roller, spray or immersion.
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 time is 6-12 hours @ 20°C / 65% relative humidity
- Protect externally treated surfaces from exposure to weather for 48 hours immediately after application
- Minimum temperature for application is 10°C
- Do not apply to frozen substrate
Please Note: Drying times are dependent upon the absorption characteristics of the substrate and drying conditions. At low temperatures and/or conditions of relative humidity, drying times will be extended.
Zeroflame Fire Retardant Treatment does not need anything to be applied over it, however where a final decorative finish is required, a water-borne, non-flammable varnish, wood stain or paint 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.
Fire retardant properties will remain effective for the lifetime of the substrate.

- 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 AFTER application of Zeroflame Fire Retardant Treatment may help overcome this phenomenon if it is unacceptable
- Zeroflame Fire Retardant Treatment is not suitable for veneer, plywood laminates, wood-derived particle board or similar as it cannot penetrate. Zeroflame Fire Retardant Paint or Thermoguard Fire Varnish BS Class 1/0 & EN Class B System is recommended instead
