Recommended Primers

A range of primers have been fire tested and approved for use under FIRETEX FX5120. For use on concrete, a number of Epoxy Primers have been approved.

Must not be applied directly to galvanized steel, zinc rich primers or concrete. 

Recommended Topcoats

If it can be guaranteed that application and subsequent in-service conditions will be in a C1 environment as defined in ISO 12944-2:1998, then no topcoat is required.

For any other situation a topcoat must be applied, consult Sherwin-Williams for advice.

The above products should be used for subsequent re-decoration. 

Additional Notes

In common with other water based coatings, the drying of this material is retarded by high humidity conditions. Lack of air movement also slows down the drying process, and under such conditions it is advisable to introduce some method of circulating air over the coated surface in order to speed up the drying. A ventilated air speed of 2 metres per second is recommended.

Numerical values quoted for physical data may vary slightly from batch to batch.

questions Aleksandrs on 2019-08-06 10:56:06

Hello! Which product do you recomend for application for steel structures that will be used (commisioned) in cold storages (-25C). Fireproofing calculations for R30, 550C. Can FX5120 be used?

Answer from Rawlins’ Technical Team: 

Thank you for your enquiry, in order for us to be able to answer you query, please provide us with as much of the following information as possible;

  • Level of fire protection required (i.e. 30, 60, 90min, etc.)
  • Each steel section dimension (i.e. 254x146x37 UB)
  • Quantity and length of each section (or overall meterage for each section)
  • Orientation (horizontal or vertical)
  • Number of sides to be painted (all sides, 3 sides, 1 flange, etc.)
  • Environment (internal, external, car park, chemical exposure, etc.)
  • Application on site or in shop

Alternatively you can just forward us drawings, fabrication/cutting lists and we'll extract the information from them but in that instance we'd need some guidance as to what to allow for i.e. all steels on first floor, etc.
