Thermoguard Thermoproof Exterior Fluid is a fire proof fluid for bare timbers such as sleepers, fencing, cladding and decking. The fluid penetrates deep into porous wood and when exposed to fire creates an inert layer to help insulate the wood.
The weather resistant, water-based, non flammable formula enables safe application by untrained and inexperienced users. Durable clear fire and flame resistant fluid for exterior wood which allows the wood to weather naturally.
Thermoguard Thermoproof Exterior Fluid must be able to penetrate the wood in order to be effective. Any water resistant coatings, sealer coats, waxes, paints or waterproofing treatments must removed before application of the fluid. Try Thermoguard Thermostrip
