Thermoguard Timbercoat

Fire Protection and Decoration of Wood in Buildings

Thermoguard Timbercoat

Thermoguard Timbercoat is a durable, wear, weather and wash resistant fire protection paint for decorative interior and exterior timber surfaces. Thermoguard Timbercoat meets new Fire Regulations standard BS EN Class B s1 d0 and complies with British Standard Class 1 and Class O Surface Spread of Flame. Thermoguard Timbercoat can also achieve 30 & 60 minutes Fire Resistance in certain instances, see Thermoguard Timbercoat 30 & 60 Minute System.

Intumescent and Water Vapour Action

When exposed to fire:-

• Smoke & Flame Retardant Dualcoat releases a vapour to suppress toxic gasses & prevent flamespread.
• Thermoguard Timbercoat expands to create a barrier, insulating wood from heat and oxygen to prevent wood burning & fire penetration

Finish, Colours, Spread Rate and Pack Sizes

• Smoke & Flame Retardant Dualcoat is available in Matt or Eggshell finish in White, BS 4800, BS 381C, RAL and NCS colours (not metallic or fluorescent shades)
• Timbercoat is available in White as standard but can also be tinted to BS 4800, BS 381C, RAL and NCS undercoat shades
• Timbercoat and Smoke & Flame Retardant Dualcoat are sold in 20m² and 80m² cans

Specification & Application

Prepare & apply according to manufacturer’s instructions

• 1 coat of Thermoguard Timbercoat
• 1 coat* of Thermoguard Smoke & Flame Retardant Dualcoat

*Apply 2 coats of Thermoguard Smoke & Flame Retardant Dualcoat for external or damp areas. 2 coats 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.

For 30 & 60 minute protection please see Thermoguard Timbercoat 30 & 60 Minute System.

For fire protection to doors, see Fire Door Upgrade Kits

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.

Spray equipment suggestions for Thermoguard Timbercoat and Thermoguard Smoke & Flame Retardant Dualcoat;

OR

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

Ensure coverage is applied as per can - i.e. 20m² can covers 20m², 80m² can covers 80m², etc.

Application to OSB/Sterling Board

This is a board made of chips of wood glued together to form a hard non-decorative board. If it needs fire coating, Thermoguard Fire Varnish or Timbercoat System can be applied to it to acheive BS Class 1/0 and EN Class B only. However we first recommend a test is carried out by applying a small amount of the proposed coating to the board to check for "cessing" / "cissing" (where coating gathers together in lumps and may leaving bare patches between). If this occurs the board should be degreased/cleaned and allowed to dry before testing again - if this still does not provide a satisfactory application please contact our Technical Team for further advice on 0113 2455450 (option 2) or send a message to [email protected]linspaints.com.
