Project Description
Thermoguard Fire Varnish basecoat is the intumescent part of a varnish system for Fire Protection of new and previously varnished timber and timber derivative substrates.
Special formula provides tough, durable protection to internal and external wood.
Clear or stained varnish finishes enhance the natural beauty of the wood.
Fire Varnish Overcoat matt or satin provides protection against UV and wear.
When exposed to fire, Thermoguard Fire Varnish basecoat expands to create an insulating barrier, protecting timber surfaces from flames, heat and oxygen and suppressing emission of deadly smoke & gasses.
- Saves Money and Time!
- Class 1, Class O, new Class b s2 dO –
Interior – 1 coat basecoat + 1 coat Overcoat – 2nd coat for stained varnish
Exterior – 2 coats Exterior Overcoat. - For 30/60 minutes – 3 coats basecoat + 1 coat Interior /2 coats exterior Overcoat.

Fire Varnish Overcoats available in a range of woodstain shade shades:
www.thermoguarduk.com/bs-ral-colours-woodstains-charts/
OTHER WOODSTAINS, WOOD-DYES Etc
Recommended. Penetrating Wood Dyes / Spirit Stains based on low flash solvents (eg Xylene, Toluene, Alcohols) Benefits are – Quick drying, do not seal wood.
Acceptable. Penetrating Wood Dyes based on Water (not water repellent)
Precaution – wait for all water to come out of wood before overcoating.
Usable with Caution. Nitrostain, White Spirit Penetrating stains (single coat of matt only)
Precautions-Allow to dry thoroughly (up to 2 weeks for white spirit) Degrease with warm detergent solution necessary with some sanding required if a solid film has been formed.
Not Recommended. Stains containing Water Repellents, Waxes, Oils, Coal Tar Distillates / bye-products, satin or gloss woodtains or other stains which seal the wood or stains that deposit a weak film of underbound pigment. “Home recipes” combining stains and lacquers.
N.B. Consult Thermoguard Technical if these have been applied already or if in doubt.
Compatible Pre-Existing Coatings
Long oil Varnish, Yacht Varnish or Polyurethane Varnish- Require thorough sanding to give a “key”.
Non water-repellent organic solvent preservative (provided thoroughly dry).
For others please consult Thermoguard Technical.
Incompatible Surfaces. Photographic faced hardboard, CCA “Tanalised” or water-repellent grade preservative treated timber. Emulsion paint, old “1st generation” type clear fire coatings ***
***If these may be present, contact Tech Dept for specific advice, tests etc.
Paint
Paint should be overcoated with Timbercoat & SFR Dualcoat in chosen BS or RAL colour, Because > Paints cannot be successfully coated with a clear fire varnish because – adequate abrasion of hard or smooth paint damages the colour, while softer emulsions & acrylics cause varnish to craze or shrivel
Important Application Notes
- basecoat is abraded to obtaing a key with 120 grit abrasive
- apply a light coat of basecoat to replace material removed during abrasion
- apply Overcoat within the ideal window or as near to it as possible
