water proof paint for basement
If you get water in basement when it rains it will help some.I put 2 coats of this on my neighbors basement and she still gets water.
All I can say is it will help,this is about $20.00 a gallon.You need to put it on with a nice big brush do not roll,and yes the paint is gritty and chunky to answer your question early for when you open the can.
It will do NOTHING to keep out gaseous water or water vapor, however.
That said, one usually need sto apply BOTH a product like ThoroSeal And a vapor barrier coating like DryLok to keep out both liquid and gaseous water from a basement.
