skimming already skimmed walls

[andreas]

I had 2 walls partially re-skimmed, above cabinets, due to damage caused removing tiles. They did an okay job, scored and sealed the walls first and put 2 coats over. It was not a great job though a bit uneven. Plan has now changed and cabinets are being removed. Due to unevenness of upper section I am thinking to have the whole wall re-skimmed completely. Is it O.K. to keep skimming a wall? At the moment upper section has brick > base render > original plaster > skim plaster (about 4mm thick) so would then have a second skim assume around 4mm thick on top of that.

If O.K. to do any extra precautions or steps?

You should just be able to PVA the wall, but then I'd never do less than 2 sets over PVA, if you want it perfect.

would get 2 coats done as usual I just was not sure if there would be any issue with re-skimming a wall that's already been skimmed on top of the original plaster.

None whatsoever, and even less of a worry here as you’re skimming new over new.

 

This is perfectly fine for refurbishing old houses, so fill your boots. 🥾
