To touch: 3 hours 1½ hours
To recoat: 6 hours 4 hours
To handle: This will depend on the total thickness of FIRETEX FX5062 to be applied.
These figures are given as a guide only. Factors such as air movement and humidity must also be considered.
A range of primers have been fire tested and approved for use under FIRETEX FX5062.
Please consult Sherwin-Williams for detailed information.
Must not be applied directly to galvanized steel and zinc rich primers.
If it can be guaranteed that application and subsequent in-service conditions will be in a C1 environment as defined in BS EN ISO12944-2:2017, then no topcoat is required.
For any other situation a topcoat must be applied, consult Sherwin-Williams Customer Service Department for advice.

6 months from date of manufacture.
This is designated by the "Use by" date on the pail. Both transportation and long term storage of the product must be in a covered environment, out of direct sunlight and in the temperature range 5° to 35°C.
Protect from freezing at all times.
Ensure surfaces to be coated are clean, dry and free from all surface contamination.
Application Conditions and Overcoating
FIRETEX FX5062 must be applied in a dry internal environment. It must not be exposed to condensation, damp or wet conditions during or after application.
In conditions of high relative humidity good ventilation conditions are essential. Substrate temperature shall be at least 3°C above the dew point and always above 0°C.
At application temperatures below 10°C, drying and curing times will be significantly extended, and spraying characteristics may be impaired.
A minimum ambient air temperature of 5°C is required to ensure proper film formation.
Relative humidity should not exceed 80% to ensure proper film formation.
Extended overcoating times may be required at low temperatures and/or high film thicknesses.
Occasionally impaired film formation such as cracking may occur on edges of flanges and external or internal angles of structural steel, depending on geometry, over-application and ambient conditions. This does not detrimentally affect the fire performance properties of the product.
If it is desired to overcoat outside the times stated on the data sheet, please seek advice of Sherwin-Williams.
