Recommended Primers

A range of primers have been fire tested and approved for use under FIRETEX FX5090. Please consult Rawlins Paints for detailed information. Must not be applied directly to galvanized steel and zinc rich primers. 

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 our Technical Team 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 Terry  on 2022-09-07 13:22:15

Hi Just wondering how much m2 would the 20litres cover? Would need to cover 478 steel plates at 400x400mm per plate. Have done a calculation of roughly 7.5m2 per 20liters , would this be correct? Can't seem to find the m2 coverage in information sheets. You're help is greatly appreciated. Regards, Terry

Answer from Rawlins’ Technical Team: 

Thank you for the enquiry, unfortunately this product does not have fixed coverage rates and a specification will be required.

Please send the information below to [email protected]

- 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.)
- Structural Steel Design Code (i.e. EuroCode, BS5950, BS476; Part 21, etc.)
- Building type (i.e. office, domestic, storage, 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.
