Hi all, recently I got an underground leaking pipe fixed in the kitchen, removed the lino and been drying out the cement since, it was very wet. I have noticed a number of small patches of white mould on the cement. Should the whole floor be treated before I get it tiled.
It has been a week drying out and probably has another week to go, but will this disappear when fully dried?
Thanks for any help.
Could it be salt leeching out of the cement ? (you see it on brick walls sometimes)
Its almost certainly not mold,but efflorescence - salts carried out of cement by water moving through.
If you are tiling, brush it off and tile away.
BUT i'd wait a few weeks to get the floor really dry beforehand.
