INTUMESCENT FIRE PROTECTION When exposed to a fire Intumescent Timber Varnish expands to create a fire resilient barrier, insulating and protecting the timber surfaces from heat and the oxygen required for fire.
Flame Varnish v. blowtorch - note, no flames. SAFE MINIMUM THICKNESS OF WOOD - for 30 Minute Standard Softwoods need to be at least 16mm thick and hardwoods 12mm thick in order to withstand 10mm (softwoods) or 6mm (hardwoods) of 'charring' without collapse. If the wood is less than these thicknesses it can be supplemented with additional panelling - we will be please to Quote for precision panels made to measure for your project. These can be sealed in place with our Intumescent Mastic.

FINISH AND COLOUR RANGE Intumescent Timber Varnish is clear and can be overcoated only with the following decorative clear finishes: Fire Varnish finish - top coating: Available in Gloss, Satin or Matt - it is clear, with no colour. COVERAGE Class 1 and Class 0: Apply 2 coats of Intumescent Timber Varnish at 6.5 square metres per litre per coat. 30 Minutes: Apply 3 coats of Intumescent Timber Varnish at 6.5 square metres per litre per coat. In all cases apply at least one coat of Fire Varnish finish at 10 square metres per litre per coat over the Intumescent Base Coats. APPLICATION METHODS Brush, roller or spray. Contact us for spray equipment advice WARNING - The base Intumescent Varnish is a water containing Epoxy, two pack product. It must be very thoroughly mixed in the supplied proportions for at least 3 minutes. ALWAYS apply a small test patch and wait until fully dried before proceeding with full coating. Uneven drying or patchy coverage may indicate 'cissing' - a condition caused by lack of surface preparation. If this occurs please consult us for help. APPLICATION CONDITIONS (critical) Ensure surfaces are clean and dry. Maximum timber moisture content 18%. Maximum relative humidity during application and drying 65%. Minimum surface temperature 3°C above dew point, and at least 8 degrees C. Important warning - these Varnishes will take longer to dry in cool conditions. Do not overcoat unless the previous coat is totally hard and completely tack free. METHOD AND DRYING TIMES Prepare the surfaces by cleaning with a degreasing detergent (e.g. Sugar Soap) and abrading to an oil free, matt finish. Carry out a water droplet or Emulsion Paint dab test - if a water droplet is absorbed or ordinary Emulsion Paint spreads and dries without 'marbling or cissing'. Then try a test patch with the Intumescent Varnish. If it puddles, marbles or pools it will not set properly and the surfaces need more preparation. This problem is called 'cissing' and usually indicates that the surface is repelling the Varnish - it may be affected by wax, oil, natural resins in freshly planed timber, timber treatments, greasing hand prints. If 'cissing' occurs repeat the Preparation process and then call us for help. Apply one coat of Intumescent Varnish (Epoxy based, two pack - if part mixed, use 2 Base to 1 Activator, or the complete pack.). If the first coat does not spread evenly and set in a totally uniform coat you must strip the surface back to bare wood and solvent clean. Check that the surface will absorb water (droplet test) before re-coating. After 24 hours (minimum) apply the second or third (subject to Specification) coat of Intumescent Varnish (Epoxy based, two pack). Leave these two, three or four base coats for 7 days to initially cure. This allows moisture to leave the product. Ensure adequate ventilation and heating during this initial drying period. Apply one or two top coats of Finish Varnish, with a minimum drying time of 24 hours between coats. Ensure adequate ventilation and heating during drying, but do not accelerate the drying of these coats with more heat, or directly applied heat - this may cause crazing or cracking of the finish coats.
