What i always thought was damp in avery small area of out lounge turn out to be salts or efforesence coming up and rotting the wallpaper making it look like damp... Anyway 2 mths ago the small area was hacked out and replastered.... I bought some salt away for the area as treated as instructed..... I let the area throughly dry and now lined over it.. What i would like to know from papering the area again how long before the salts or efforesence take to come through if its not worked...... Ta
If it hasn't worked I reckon 2-3 weeks max. before crystals start appearing Welcome to my world. I have a small issue on the front faces and inside faces of an opened up chimney breast that has had 110 years of continuous coal fires in it. I D&D fireproof board on and the wet in the dabs caused salts to come out the chimney where the dabs were. As yet I haven't managed to totally tame them. I am hoping once I get the stove in it will keep the efflorescence down (it's basically the salts absorbing water vapour out the air and/or any residual moisture in the wall coming out) I suspect my walls have a fair bit of trapped moisture inside the salts in the bricks. I did make the mistake, when the house was mid-refurb of jet-washing the back wall of the fireplace to clean it so I could keep the bare brick finish at the back. I suspect a fair bit of this water got absorbed into existing salts. At the moment, the solution is a quick sand and a coat of emulsion (mine is not papered) when crystals appear, and see if in time it goes away - it is reducing. Ultimately, I think the solution if it doesn't go by itself, is chop the brick out and replace with new concrete blocks.
Well i gave it a dose like the salt away bottle says and that was 2 weeks ago i think.. Ive waited until its dryed before giving a pva coating. Ive lined over it so its a waiting game.. I must say that after the initial dose of salt away nothing as appeared yet.... Time will tell.....
