Painting water damaged wall

[Aidan123G]

Was looking for some advice on how to deal with a water damaged wall from a leaking box gutter. The gutter has now been fixed and I was wondering if the wall can be sanded and painted or will it require skimming.
Any advice appreciated.
Regards Aidan.

Orbital sand area. 5 to 1 pva.
-Toupret filler over area. Sand. Paint. See if it stains and if it dose stain block. Rattle can of BIN warmed up is easiest to block stain or roll some on if you prefer

Cheers Wayners, really appreciate the quick reply. Going to give the gutter about a month to confirm no more water then crack on with it.
Many thanks Aidan.
