I am about to paint a wall (emulsion) that has a couple of grease stains on
it, would PVA act as a sealer? The 2 spots of grease are about 4 cm in
diameter.


You can try it and let us know because my kitchen has a few near my bin that
I want to paint over, I don't know that PVA would stick to grease though -
you may have to sand it a bit first to give it a key.



Give it a scrub first with sugar soap - that takes rather more grease
out than basic detergents.
