Im currently doing a kitchen,one of the walls above a worktop bows inwards almost the full length of the wall and has a gap in the middle of about 15 mm.The wall is just a basic wall with no plug sockets or anything and is about 1.6m x 0.6m with cupboards above.I have tried to bed the adhesive out but is turning out a bit too much hassle.Would you reccommend just skimming the wall or do you have any tips as i can see this being an issue quite often?Also what is the maximum gap you can have before it needs plastering? many thanks guys.

Have you got enough play to put some board on?thats what i would be looking at to flatten it out

I would have skimmed up the wall with rapidset using a plasterers float to get flat. may have to have been done in a couple of hits though, first skim with a shorter straight edge.

Yeah i could use board.Would normal plasterboard be ok or would you use wedi board? I may have a small bit of flex in the middle tho,could i use anything to support this behind? Thanks for the replies

if you use plasterboard adhesive you can put enough behind the board to give you a solid face in the area where the depression is.

cheers grumpy i think that board would be the better option.

would you recommend a plasterboard adhesive too cheers

Someone mentioned expanding foam on a previous post squirt behind to push the board out
