System

10mm + thickness boards/3mm loss to char beams & joists (see below red text for full details)

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

15mm + thickness boards/7mm loss to char beams & joists (see below red text for full details)

• Apply 2 coats of Thermoguard Timbercoat @ 4m² per kg/per coat

Either application of Timbercoat should always be followed by;

• 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 30 minute protection minimum wood thicknesses apply of which approval must be sought before purchase.

Drying Times

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

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

Preparation & Application

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.

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 Disaster” 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

• 30min protection - 10mm + thick boards minimum (select ‘10mm + thickness boards/3mm loss to char beams & joists’ above when ordering)

• 30min protection – 15mm+ thick boards (select ‘15mm + thickness boards/7mm loss to char beams & joists’ above when ordering)

Beams and Joists

• 30min protection - For wood which can afford to lose only 3mm to charring from exposed faces without collapsing, flame penetration or excessive heat penetration (select ‘10mm + thickness boards/3mm loss to char beams & joists’ above when ordering)

• 30min protection - For wood which can afford to lose 7mm to charring from exposed faces without collapsing, flame penetration or excessive heat penetration (select ‘15mm + thickness boards/7mm loss to char beams & joists’ above when ordering)

Application to OSB/Sterling Board

Only surface spread of flame protection can be provided to OSB, for BS Class 1/0 & EN Class B s1 d0 ONLY see Thermoguard Timbercoat BS Class 1/0 & EN Class B System for details.

Spray Equipment Suggestions

• Pressure Pot & Gun conventional unit with small compressor
• Ensure all traces of solvent flushed out
• Thin 5 > 10% with water to spray viscosity
• Adjust fluid flow & air flow as normal for acrylic emulsion paint

OR

• Airless Graco 1500, 3500 or equivalent
• 3/8” line, 30 mesh filter on machine, not filter in gun
• 521,523, 621 or 623 tip

Ensure coverage and product quantity is applied as per specification.
