I have Mark's on my sitting room wall

dubdvd

I have Mark's on my sitting room wall from mushrooms I used to fix damp boards to my wall in my sitting room they are only on the exterior facing wall . I looks like lots of 2 ' grey circles I painted it last year and due to this I'm about to do it again . My question is what can I use to cover this before I paint it again ?? is it primer or a Damp coat ??

Wtf ?

Use some white gloss paint over the spots before you paint it again. 2 thin coats and let it dry. Bingo !

Don’t do this as the gloss will be oil based and the emulsion won’t adhere to it

Try a shellac based primer, give the marks two coats of primer and then carry on with the emulsion. If it bleeds through the shellac primer then it’s still damp behind

I just spray mine with a mildew and mould spray. Does the job.

This is the best advice, seal and then do a coat of emulsion over it.
