I was wondering if anyone here had any comment about the white marks on
the bricks. Is this effloresence? Do all bricks do this or is this a
sign that these are not of low salt content thus I would need to use
sulphate resisting cement? Does the white go away once washed off?


Its not salt as you think of it, but salts ie chemical compounds formed
from the reaction of acids and alkalis.
