Is it ok to use white undercoat instead of white emulsion paint.
I would need to buy the emulsion but unfortunately I am overspent at them moment!

This is the bqackground. I found I have got a nearly full 10 litre tin of Johnstone high opacity white undercoat.
I want to re-paint the inside of a cupboard which has brick walls and is plastered in the same way as conventional indoor walls are. The cupboard walls are already painted white but it was several years ago.
I just wonder if undercoat might change colour over time or might be poorer wearing or might have some other disadvantage? Can someone advise please.
