(OP)
Do you spec structural steel receiving fire spray to be primed if it is in non-corrosive environment? . What is the standard practice?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Interior Steel receiving fire spray
The removal of loose mill scale and surface contaminants is generally required before application, so that the bond between the coating and the steel is not compromised, whether it is the direct applied SFRM or the primer for an intumescent coating.
RE: Interior Steel receiving fire spray
So, for the cementitious SFRM it is a no no and for intumescent it is yes. Why?
If corrosion is a no problem then priming should not be required in either case and if it is bond problem, I think the SFRM doesn't provide corrosion protection. Do you prime steel not receiving fire protection in a non corrosive environment?
RE: Interior Steel receiving fire spray
Intumescent is a paint so it's no suprise that a suitable primer will increase bond.
