Pan fire

[STI]

Hi,

Bought a house where they had had a chip pan fire. The walls and ceiling are covered in a black film. Does anyone have any suggestions on how to get this off ready for decorating. The walls and ceiling are painted in a silk finish. I have tried soap and water it gets some off but there is still a black stain left in place, i tried soap and water and imediately vacced this with a wet and dry. This lifted the dirty water but then left a dirty black gathering when i lifted the vac head.

As a follow on question, all the ceilings need to be re boarded. Can i just put new boards over the old or do the old have to come down.

Trying to save time and mess
Thanks

Just reboard over the old ceiling. I have done this through out my house.
(and have it plastered)

You can try using sugar soap and then rinsing with clean water, or to seal the affected areas you could as your first coat apply an Alkali Resistant primer. prior to re-decoration.
