Internal plastering - scud coat or not

Dugsy

Just about to start the internal plasterwork. My plasterer is telling me that a sand and cement scratch coat and top skim coat are all that is required. Is an initial scud coat required or is that just used on the external walls?

Poor Uncle Tom

A scud coat is used to provide a key between the blockwork and the plaster/render coat. So, it is wise to use it wherever there is a blockwork wall needing a plaster or render finish in case the blockwork is not rough enough on its own to take a heavy coat.

Can I ask you,for some advice please?

I had my fireplace replastered recently.The plasterer used a scatch coat on the bare brick,and then a top plaster coat applied.But the plasterer will not come back to re do it,just keeps on giving me silly excuse afer silly excuse.:mad:

I havent used my fireplace yet,but the plaster is cracked to bits,long cracks all over the front and sides of the fireplace.

A different builder told me the best solution is to scrape off all the plaster and re do it from scatch.

But he says that a large sheet of plastering mesh put up on the chimney breast wall will prevent any cracking in the future.

Does this sound right,as I didnt know that there was such a think as plastering mesh sheets??

Thanks.

From what you describe I agree with the builder about using the mesh for your fireplace wall
It will actually help prevent cracking where you will have temprature varients.

Thankyou,good to know that the builder is talking sense to me,as after the hassle I had with the last builder and plaster,er I was a tad wary of what I was being told this time around.

Thanks again.:)
