Painting over cooking oil

[emmaamme]

My husband managed to cover the kitchen ceiling with cooking oil when it all splattered out the pan on the hob. There's hundreds of drops on it looking a real mess. I tried painting over them this afternoon with emulsion only for them to show through again.
Any ideas around this before I kill him? I have zinnsser perma white mould resistant satin paint which has a built-in primer. Would it work covering the stains and then applying emulsion?
Many thanks.

Give it a try ,if not it's stain block you need

Trying to figure out if your husband did that on purpose to get out of cooking !

I wouldn't care but he used to be a chef! No excuses .
Thanks - would you recommend something like zinnsser B-I-N?. Really don't want to do whole ceiling as it's quite an area so would just be dabbing it on.
(Tried the zinnsser perma white on a small bit but didn't work)

Have you tried kitchen paper held to the wall with an iron?
It may help to draw the oil out of the paint

Obviously don't set fire to the paper/ get the iron oily or scorch the paint

Hi Emma
Go for the Zinsser BIN, being based on shellac (soluable by methylated spirit) it's the best stain covering compound there is, in my opinion.
Better than the 123 mix, which is water based.

Thanks John - I'll see how it looks in the morning then order that if needs be. Nice to hear from you again.

Nothing worse than vegetable oil for sticking, Emma - I think covering is your only option!
