The special formula provides a tough, durable finish to internal and external wood. 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 (a two component product consisting of a base and activator mixed together before use - see image above) 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.
