Hi Guys, looking for some advise, we have a room attached to the house ground floor it is double skinned brick walls but no cavity 3 of the walls are outside walls all sound , basically we had a plasterer out to plaster it for us he said he would need to put a sand and cement base coat on before the plaster , he did the sand and cement coat on the Saturday then came back the next morning to do the skim , after a week I started to get air line cracks all over the walls the plasterer told me this was a settling process , then I notice when pressing in certain areas I could ear a cracking sound , We got the plasterer out he said the areas with the crackerling sound had not stuck to the wall properly he told me he would chip away the bad bits and use hardwall on them areas and re skim , the problem is im a little confused its just when he first came out he said he could not use hardwall due to the walls being non cavity and outside walls ?? But now he can :?:
Would be grateful for all advise , Thank you
