I've just been to look at a ceiling that a customer has already boarded out, not sure what to do now. Not only are the joints all meeting ie crosses everywhere no staggering, but every board is the wrong way round cause 'they're getting plastered and not painted' (I don't know either) . The old boy looked so proud so I didn't have the heart to tell him. It's in a loft, so not full ceiling, infill between joists, 1.2 x 4m. Do you think I could pva a couple of coats and skim OK? Use big pieces of fibre glass on the bad joints? Sorry if this is obvious but I'm fairly new to plastering and I've never seen this before! Cheers.
