Hi, a novice here and i have such a small job most plasterers wont even come to look.
Recently moved into an old renovated barn, all internal walls are celcon/thermlite blocks and some bright spark decided to chase and backfill hot and cold water pipes into the walls.
I have a 30mm deep, 200mm wide and 6ft long wobbly channel running down my walls. I want to fill and reskim ready for decorating. I have spoken to gypsum who were useless, so im after some advice
1) Is hardwall the best plaster to build up the depth before skimming?
2) do i need to build up using 2 or 3 layers and if so how long between next layer
3) do i need to use pva solution or gypprime before the hardwall to help reduce drying?
4) i was thinking of using some expanded aluminum mesh in the hole to give a bit of strength is this a good idea?
5) Once the backing plaster is in i may not be able to skim it straight after as i work away. It may be left a week before i get to skim, do i need to do any prep to the backing before i skim?
