Product Description

Sherwin Williams Firetex FX1003 is a single pack, thin film 120 minutes intumescent coating designed for site application via airless spray onto structural steel.

Best Uses

FIRETEX FX1003 is designed for site application by airless spray, to provide fire resistance for up to 120 minutes on structural steel. After appropriate drying, FIRETEX FX1003 specifications can be exposed to the weather for up to 6 months provided that the specific use does not lead to ponding water due to rainfall, condensation or other site circumstances.

FIRETEX FX1003 can resist normal weather conditions for up to 6 months without topcoat provided it has had appropriate drying prior to exposure. Once an approved topcoat has been applied as appropriate to the prevailing conditions, then durability will be substantially enhanced. If the specific use or storage could lead to prolonged contact with water due to rainfall, condensation, or other site/transportation/storage circumstances, then a recommended topcoat must be used to prevent damage to the base coat.


Recommended application via airless spray or brush. For certain dry, internal situations where the final colour / appearance is not critical, then FIRETEX FX1003 may remain un-topcoated. For externally exposed steelwork up to C4 and severe internal environments Acrolon C137V2 or Acrolon C237 must be used as a topcoat. For other internal environments where a topcoat is required then FIRETEX M71V2 or Sher-Cryl M770 should be used. In all instances for subsequent re-decoration, use FIRETEX M71V2, Sher-Cryl M770, Acrolon C137V2 or Acrolon C237 as appropriate.

FIRETEX FX1003 is designed for use over a suitably prepared and primed substrate. Ensure surfaces to be coated are clean, dry and free from all surface contamination. Under certain circumstances it may be possible to apply FIRETEX FX1003 directly to steel blast cleaned to a minimum standard of Sa2½ BS EN ISO 8501-1:2001, surface profile in the range 50-100 microns. FIRETEX FX1003 is capable of withstanding external exposure without topcoat providing:

The product is allowed to dry for at least 24 hours at 15°C in dry conditions with good air movement and ventilation. These conditions are based on a total dry film thickness of up to 800 microns. The drying time required will be increased if the film thickness is greater than 800 microns.
The substrate temperature is at least 3°C above the dew point at the time of application and during the drying period.
