Hey guys - I'm a novice to this whole home improvement thing so was looking for some advice. I live in Cleveland in a home that is over 70 years old. The basement has slight moisture issues. I don't have puddles but there is always a few spots on the floor and near the walls that are damp. The spots are never bigger than, say, an iPhone. The block walls were painted previously and are now bubbling and peeling. The floor was also painted and has almost completely flaked off. The walls have some small black areas from moisture, though I am not sure if it is mold (it doesn't look like a growth and hasn't changed or expanded). First question - can I use a pressure washer on my block walls to remove the paint? It is a fairly large area and in the interest of time and laziness this would be the easiest method. I have a drain in the basement and a dehumidifier to try to remove the moisture after I am finished. I don't want to damage the walls. Second question - can I use a product like Drylok on the interior of the walls? If moisture is coming through now, I am concerned that a product like this will just trap that moisture in the blocks and cause further damage. This is a starter home and I won't be here longer than 5-7 years so it isn't worth digging out the outside of the house and resealing the entire place. I need a cheap but decent fix so my wife isn't terrified to go into our basement.
