Thermoguard Thermoproof Interior Fluid is a clear, colourless, one coat penetrating fluid for fire protection on wood. There is an optional sealer to give a wipe clean surface on wallboards with protection against wear, damp and UV. In a fire, the Thermoproof fluid reacts with the woods cells to create a flame & heat resistant barrier. The optional sealer is flame-retardant. Resists light cleaning & handling. Allow Thermoproof to fully dry (min. 4 days) before applying any sealer.

For treatment with Thermoproof to be effective, it needs to be able to penetrate the wood. Thermoproof can be applied over water-based penetrating wood dyes that do not make wood water-proof.
Please Note: If certification is required, an intumescent enquiry form must be completed prior to purchase of the product, as this will ensure the correct quantity is applied to achieve the fire rating. The enquiry form is available to download from the ‘Data Sheets’ tab.
