Thermoguard Timbercoat 60 Minute System - Choose from 4000+ colours available from RAL, BS & NCS

Thermoguard Timbercoat 60 Minute System is a coloured intumescent paint system for interior and exterior timber surfaces. These packs has been created to help users ensure they are purchasing sufficient product for their project. Each pack contains the correct amount of basecoat (Timbercoat) and topcoat (Smoke & Flame Retardant (SFR) Dualcoat) to ensure protection is achieved inline with the manufacturers recommendations to the respective area in question.

Each component of the packs can still be purchased individually if required here: Thermoguard Timbercoat and here: Thermoguard Smoke & Flame Retardant (SFR) Dualcoat

For fire protection to doors, see Door Upgrade Products

For BS Class 1/0 & EN Class B only see Thermoguard Timbercoat BS Class 1/0 & EN Class B System

For 30min protection, see Thermoguard Timbercoat 30 Minute System

• 28m² Pack (Exterior Spec) = 1 x 20kg Timbercoat + 1 x 20m² & 1 x 40m² Thermoguard Smoke & Flame Retardant (SFR) Dualcoat

System

• Apply 3 coats of Thermoguard Timbercoat @ 4m² per kg/per coat

Followed by either;

• Internal Applications: 1 coat of Thermoguard Smoke & Flame Retardant (SFR) Dualcoat Satin or Matt
• External, Damp or High Wear Applications: 2 coats Thermoguard Smoke & Flame Retardant (SFR) Dualcoat Satin or Matt

2 coats of Thermoguard Smoke & Flame Retardant (SFR) Dualcoat may also be required for strong/dark colours - Thermoguard Timbercoat will be provided in a suitable undercoat shade to aid topcoat opacity unless instructed otherwise.

Please note: Timber must be clean and thoroughly dry prior to application (maximum 18% moisture content). Any gaps should be sealed with Thermoguard Intumescent Mastic. Fire should be prevented from accessing unprotected wood surfaces and for external applications it is recommended wood has been sealed on the reverse face to stop water ingress.

NOT suitable for the topside of floor surfaces that will be trafficked/walked on.

To achieve 60 minute protection minimum timber thicknesses apply of which approval must be sought before purchase.

Preparation:

All surfaces must be clean and dry. Remove all possible surface contaminates such as grease, smoke residues, silicates etc. Seal water-stain risks with stain blocking sealer suitable to overcoat with water-based acrylic paints. Abrade hard or smooth surfaces with wetted 120 grit wet-or dry abrasive or dust extracting abrader. Rinse off slurry while still damp. When dry, remove any loose or suspect material back to firm edge. Fill and repair any damage to the substrate using a good quality remedial filler.

Application:

Apply Thermoguard Timbercoat and Thermoguard Smoke & Flame Retardant (SFR) Dualcoat at rate stated on specification to protect surfaces & enable project Certification.

Touch Dry: 1 hours / Overcoat: 4 hours in normal conditions.

Ensure fully hard dry before next coat, only apply to dry timber in good drying conditions.

IMPORTANT - The below information from the manufacturer must be read and referred to your relevant authority for approval BEFORE purchase and use.

Half Hour and 1 Hour Resistance To Wood

In line with good common practice, we recommend that approval be sought for the use of our system, outlining our justification for the issuing of the Fire Certificate prior to the product’s use.

Authorities generally accept our Fire Test evidence (copies available upon request) as justification for the provision of One Hour Fire Resistance in cases such as this for up to 1 Hour Fire Resistance, depending upon the thickness of board in question.

We hold independent Fire Tests for Thermoguard Timbercoat to provide One Hour Fire Resistance to a mock-up of a ceiling comprising softwood timber boards on softwood joists, with the boards abutting one another and joined by metal tongues set into the abutting edges of the boards. Whilst the amount of residual undamaged timber was clearly adequate to have withstood office or accommodation design loads, the floor tested in the Fire Test did not have weight imparted to it, as we sought data to work from the test for sites with greatly differing make-ups.

The floor tested achieved One Hour Fire Resistance to BS 476 Part 22, with approximately 7mm of timber joist and board surfaces destroyed to charring during the test. Charring was greater up the open joints between floorboards, reaching 12mm, as one would expect being merely butt-jointed rather than tongue and groove jointed. Provided the calculated residual structure is adequate, we also issue Certification to BS 476 Part 21 to 30 or 60min Fire Resistance. The normal char factor of unprotected softwood for 60 minutes is approx 50mm, thus additional Fire Resistance provided by our Intumescent Paint was approximately 30 minutes.

A Fire Resistance test for 30mins was carried out at Warrington Fire Research Centre in January 2016 to 25mm softwood and 25mm MDF. Uncoated boards burnt through completely during the test.

• Application at 300 microns wet (12m² per 5kg) resulted in loss to char of 7mm on softwood and 5mm on MDF
• Application at 500 microns wet (8m² per 5kg) resulted in loss to char of 3mm on softwood and 2mm on MDF

Thermoguard Timbercoat was filmed by Channel 5 for documentary “Megastructures – Building from Distaster” which recorded in simultaneous parallel test to 18mm softwood that at 6mins uncoated board burnt through, while boards protected with Timbercoat @ 600 microns / 7m² per 5kg lost only 3mm to char at 45mins, with the protected board retaining insulation so that it was safe to put a hand on the reverse face while the burner continued on the front face.

Minimum timber board thicknesses;

• 60min protection - Board must be a minimum of 20mm thick, prevent flame penetration or excessive heat penetration after potential loss of 10mm to charring.

Joists;

• 60min protection - Wood must be able to afford to lose 7mm to charring from exposed faces without collapsing. Not suitable for the topside of floor surfaces that will be walked on.

Applications requiring 30 minute protection only can in most instances be achieved using a 'reduced' specification, for details see Thermoguard Timbercoat 30 Minute System
