After applying knotting solution, we painted (previously varnised) wardrobes with an oil based undercoat- (recommended to us by local DIY store).
We then went to paint over this today with a water based undercoat because we want to be able to use a water based satinwood for the final finish.
However, the paint wouldn't stick onto this other oil based undercoat and just completely separated on the surface:(
So we tried painting a patch instead with water based satinwood paint and the same thing happened. What can we put over this awful stuff to be able to continue painting the wardrobes?!
