Description

Intended Use – Clear Fire Protection Overcoat for Fire Varnish System for Interior Wood

Thermoguard Fire Varnish is a clear varnish system for the Fire Protection of timber and timber derived substrates to BS Class 1 and Class 0 Surface Spread of Flame as well as BS EN Class B s2 d0 (For 30 or 60 minutes Fire Resistance see Thermoguard Fire Varnish 30 & 60 Minute System). The special formula provides a tough, durable finish to internal wood (for exterior surfaces see Thermoguard Fire Varnish Overcoat (Exterior)). The clear finish enhances the natural beauty of the wood while providing protection against UV and wear as well as fire protecting new and previously varnished surfaces.

Thermoguard Fire Varnish Overcoat doubles up as Thermoguard Thermoproof Clear Sealer. The product is labelled on the containers as 'Fire Varnish Overcoat & Thermoproof Sealer' and is available in 20m² and 80m² pack sizes.

The Thermoguard Fire Varnish System is made up of Thermoguard Fire Varnish Basecoat which is a clear, intumescent varnish to be finished with Thermoguard Fire Varnish Overcoat (Interior) or Thermoguard Fire Varnish Overcoat (Exterior) in a clear matt or satin finish (a gloss finish is available in both interior and exterior versions in batch quantities for large projects). The Thermoguard Fire Varnish Overcoats provide protection against UV, weathering (exterior grade) and wear whilst Thermoguard Fire Varnish Basecoat provides the Fire Protection.

Intumescent Fire Protection

When exposed to fire, the Thermoguard Fire Varnish System expands to create an insulating barrier, protecting timber surfaces from flames, heat and oxygen and suppressing emission of deadly smoke & gasses.

questions Simon fowler on 14/11/2016
Question: Can this product be used straight on varnished wood, I think I've read it can but just want to make double sure before I purchase. Regards Simon
Answer: 

The Thermoguard Fire Varnish system can be applied over firmly adhered standard clear varnish. Surfaces to be coated should be abraded thoroughly with medium grade silicone carbide abrasive when dry to provide a good key.

Thermoguard Fire Varnish Overcoat (Interior) must be used in conjunction with Thermoguard Fire Varnish Basecoat and NOT on it's own to provide BS Class 1, Class 0 and EN Class B s2 d0 fire protection.
