I need to fireproof my steel. Usually I’d use fire rated plasterboard and skim cost of plaster. The height is too tight for this. So I wanted to cost with intumescent paint then plaster over this to give me the same rating. Can I do this?
You can certainly coat the steelwork with intumescent paint to provide the level of fire protection you require but you cannot then plaster over it. It would need to remain as the intumescent paint and topcoat only.
If you wish to proceed, 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.
