Prepping for Painting

[Mr Blobby]

This is probably a stupid question, but that doesn't normally stop me so here goes...

 

Plastering is done and it seems pretty good I think, but there are the dings and cracks in the usual places.  We will be getting the place spray painted as soon as SWMBO can decide a colour. 

Would it be sensible to fill in some cracks now before painting, or (as builder suggests) do this after the place is sprayed.  Is the raw plaster too absorbant to repair before painting?

 

Most of the cracks are only hairline, this one about 1 mm is the widest. A few dings where trades (and myself) have bashed into the walls.

 

I read somewhere that cracks should be dremmeled wider and then flexible filler used, is that a good idea to treat the few bigger cracks?

Once its mist coated it will show the imperfections and cracks easier. I'd do all the filling or caulking after that. I wouldn't be dremelling any cracks to make wider. A wet easi fill mix is pretty fine seems to get in cracks ok.

... thanks, this matches the builders preference to spray then touch up. 👍
