Hi. I have just had a lounge wall and large stairwell wall (that includes a window) damp proofed. Membrane, then kingspan 18 thermal board, and then supposed 2 skims. Lounge looks like one skim in places, and stairwell has a couple of vertical long humps on lines I can see. Wooden window ledge stuck out an inch, now embedded as new thermal plasterboard is thicker. Is that ok to be embedded? I had new plasterboard/wall 10 yrs ago and never saw the lines last time. Would appreciate your thoughts, especially as whether you think there are two coats, as ideally I would like them back to put the extra coat on, finish bits better, or am I being unreasonable? Photos attached. Many thanks. Sue
