I own a BISF house in Nottingham, I feel the interior wall cladding in the bedrooms needs to replaced. It appears to be hardboard that has been wall papered over. There is cracking along the board joins and some of the boards are loose.

Is it possible to replace the hardboard panels with plaster board then skim over with plaster? I’ve been told that this is not possible due to movement (expansion and contraction) in the steel frame, will just cause the plaster skim to crack.

Any knowledgable advise welcome, well any advise welcome.

Complete tosh.

The only thing that would cause significant cracks would be significant stuctural movement, which doesnt happen, and even then you have to remember the steel frame is not what youre plastering directly to, the more flexible wooden frame is which would reduce the movement ever felt by the extra layer of the somewhat flexible but equally strong top layer of plasterboard, so you’ll have no more reason for cracks in a BISF house than that of a brick built one.

Either way its a messy job I can warn you of that 🙂

My whole BISF house has been plasterboarded and fully skimmed, and considering the strong winds we’ve had throughout this time theres not been a single crack FYI – Youl have more movement but you leaning on the wall than the frame of the building flexing slightly.

Get a different plasterer
