Minerals On Cement

stacker

ohhhhhhhhhh,this is getting old.yesterday when i left the job,i asked the homeowner to turn on the water sprinkler "near" the stucco wall i had just finished.i set the sprinkler so that it would not hit the wall,but get close,hoping enough mositure would keep the wall from cracking.when i got on the job,this morning,the wall was soaking wet.and after 2 hours or so of drying it was WHITE.i think i can respray the wall,but i am afraid the minerals from the water will leech thru.
my question is,what can a man use to stop that?we talked about maybe using diluted vingar.maybe someone else has an idea.
thanks.

Dilute vinegar will work, as will a mild acid solution, (600 sureklean, diluted 15-1).
