Help - Trying to do tonight...Just pulled liner, foam falling from walls as are concrete and covered in green slime. Do I need to pressure wash them?

hi that is the question in the title. I have solid concrete walls and the foam will not stick to them. Thinking I need to pressure wash the walls and I want to do this tonight so I can start on the floor and hang new foam tomorrow and hang liner on Saturday.

Sure sounds like you do. Some pics would help us understand your situation better.
