Good morning,

My question pertains to a few interior walls in a 50 year old house that I’m going to paint. The joint seams on these walls are showing thru. However, these joint seams measure 16” x 48”, and on a wall of 12’ it resembles a patchwork quilt or some type of artwork. The next-door neighbour has the same type of house and the same wall irregularity. He has told me of the construction history. 50 years ago the builder used a new type of wallboard that was available. It consisted of 16 x 48 inch panels attached to the studs then covered with a plaster. This process measures a total thickness of 1”. Good sound deadening properties but needless to say this was labour-intensive and was no longer used. It is structurally sound but is ugly.
My question is, do I remove these finished wall surfaces and replace with new gyprok, or do I simply install new gyprok over the walls as is?
I’m a little concerned with mould and mildew (although there is none now) and with good work practices. The neighbour has suggested re-taping the present joints, but there are so many of them I’ll be there for weeks. There are no cracks in any of the joints.

Thanks,

Craig
