Salt in internal brickwork
Posted: Mon Apr 13, 2009 10:03 am
I live in an old single brick bungalow and salt keeps showing on the internal walls.I have used several sealants without success.Can anyone help ?
Its called efflorescence. Brush it off (don't wash it off - that only makes it come back again) and treat wall with an anti-alkaline primer. But you'll also have to find and deal with the source of the damp that's causing the salts to leech out of the plaster / brickwork.
Cheers
