    I have converted the back of the house and added a new room on the back of the kitchen.

    As part of the build i have taken off the plasterboard from the original back wall of the house and this will be oiled brick when the room is finished.

    On this wall there is a steel holding up the back of the house when this was knocked into in the 1970's i think.

    I was planning on boxing in the steel with a fake oak beam (using oak pieces for the sides and underside, however while it has all been exposed the last few weeks i am thinking it might look ok if this was painted a blackish colour.

    So my question is, i know i need to paint the steel with a fire paint, but can i then paint over this paint with a standard gloss etc or do i need to buy a specific fire proof paint which is coloured to the desired colour ?

    We painted grey over the standard red oxide the steel came with.

    Is that standard red paint fire proof though ? Mine is painted the same. Did BRegs have anything to say about a certificate with your paint ?

    It’s not signed off fully yet but he has seen it and not said anything about it.

    Ok i think the steel does need some fire protection with a special paint, unless it is protected by fire board. If yours is on show it should need this paint on it. I would ask him about this because even if you get a cert it can bring up issues in the future (selling etc). So worth looking into.

    The steel supporting the wall will need intumescent paint to give it fire protection. The steel supporting the roof does not need fire protection.

    Because it only applies to structural elements to the walls and floors (unless it is a portal frame when the walls and roof are combined). The roof usually burns out quite quickly in a fire and it does not affect the structural integrity of the main building. I assume it is to do with the building not collapsing on top of the fire brigade in the early stages of the fire.

    I agree with Wessex. if the beam is only supporting a roof in which the only access of for maintenance I wouldn't expect it to need fire protection.

    Beams supporting floors and accessible roofs (e.g. plant decks) need fire protection in order to allow people to escape.
