Also having a problem with effervescence, the white powder forming. I read I can just wire brush the powder and drylok will cover it. Is this true, I have linoleum flooring and do not want to deal with Muratic acid.
I put a new gutter and downspout on and extended past the grade on the house. d I am dealing with the water problem first!
NO, Drylock can only be used on previously un painted masonary.
I would go with the oil based, maybe that will cover the stains, maybe. If not, then after the Drylack cures, you can paint it( first hitting the stains with Bin)
applying DRYLOK in a closed area, such as a
basement, be certain there is good air flow. Open
windows and doors and use an exhaust fan to
provide adequate ventilation.
