Description

Intended Use – Clear Fire Protection Overcoat for Fire Varnish System for Exterior 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 system is made up of a basecoat and an overcoat that must be used together, the special formula provides a tough, durable finish to external wood (for interior surfaces see Thermoguard Fire Varnish Overcoat (Interior)). 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.

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) available 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 Brian Hepworth on 06/03/2018
Question: 

Good morning. Can your clear varnish 2 coat system work on plywood that has been painted with acrylic paint (various colours) and still be classed as fire retardant?

Answer: 

No, clear fire retardant systems can't be applied over previously painted surfaces. Certain clear fire retardant systems can be applied over existing stains and varnishes but not opaque paints. To upgrade previously painted surfaces you should use something like Thermoguard Timbercoat BS Class 1/0 & EN Class B System or Thermoguard Timbercoat 30 & 60 Minute System in the colour and finish of your choice.
