I have a cement basement floor that has never been sealed or painted. I am
getting a white residue from time to time. Bleach does not get rid of it, so
I'm figuring that maybe this is a mineral deposit? The basement has high
humidity and is musty at times. Ideas?
I was wondering if applying a seal coat would elimate this.
Thanks for any suggestions.
I would get a dehumidifier and get all the moisture out of that basement.
Then seal it with a specialty pain that will not allow water to seep
through. You'll need to keep running that de-humidifier too.
if youre in the souther states, getting a ventilated basement would
work. you have to help minimize the water going to your foundation.
start out with the downspouts, make sure they extend out from the wall
about 6ft, the further the less water outside your foundation. and
check the slope of your property, if it slopes to the house, thats
bad. water just keeps going in your foundation wall and thats whats
keeping it damp. same thing if theres a hill, water cascades down to
you. is your sump pump covered?

yah, i know that its efflorescence from that stagnant water presence
from the outside sipping through that wall. if that water drains
faster or producing less pressure for it to sip into that walln that
efflorescence would not be there. dont you think so?
