Hi,
I skimmed a wall but ended up with a slight bow into the wall which I think I can correct with another thin application of multifinish plaster. Essentially, it's not quite flat. I guess my preparation was insufficient.
I left it two weeks, applied liberal amount of 2:1 PVA, let it dry overnight and then more PVA before the attempting the skim.
As I was putting on the first (scratch) coat, within a few minutes of starting, cracks started to appear in the wet plaster. They were quite big. No way would it have been a decent finish. So I scraped it straight off.
Was two weeks too soon? Could I have used too much diluted PVA?
Are cracks are only caused when the background is too absorbent, or are there other reasons?
I'm just a DIY'er.
Any advice would be appreciated. Unfortunately I didn't think to take photos.
Thanks,
Dave.
