Treating mould/mildew wall before wallpapering

Discussion in 'Builders' Talk' started by Bargain Bucket, Oct 11, 2017.

  1. Just about to re-wallpaper a wall that until recently, formed part of a built in cupboard in the bedroom. The corner of this wall was a little damp with some mildew (mould?). I think I've rectified the source of the damp (cracked render outside) but I guess I need to treat the wall inside before I wallpaper. Any suggestions as to what in use to kill off any mildew and stop the stain from coming through the wallpaper?

    Many thanks.

    Apply a Fungicidal Wash as per instructions on container or weak bleach solution (Domestos) rinse off when dry, when that has dried apply a couple of coats of Zinsser Cover Stain to seal over the affected surface.
