Thermoguard Thermoproof Exterior Fluid

Thermoguard Thermoproof Exterior Fluid is a penetrating fire proof fluid for wood.

Please Note: Timber must be a minimum of 12mm thick for the treatment to be effective.

Intended Use

Fire protection for bare timber sleepers, fencing, cladding and decking.

Description

Durable clear fire and flame resistant fluid for external and internal wood. Weather resistant. Water-based, non flammable formula enables safe application by untrained and inexperienced users.

How it Works

Penetrates deep into porous wood. When exposed to fire Thermoguard Thermoproof Exterior Fluid creates an inert layer within the wood’s surface which insulates the wood from fire, preventing flamespread.
