A clear solution for solid timber. It is waterborne and non-toxic and can be overcoated. It is suitable for both interior and exterior use. It soaks into the wood and seals it but leaves the surfaces unchanged, so you can still overcoat with a varnish or stain. The fire protection will last for the lifetime of the wood surface.

 

  • Final Finish - Natural.
  • Zeroflame Fire Retardant Treatment achieves Class 0 on solid timber and Class 1  on veneer and plywood laminates, due to the bonding glues resisting penetration. 
  • 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. Zeroflame Fire Retardant Paint is recommended instead.

Certification

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.

  • 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.

 

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 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.
