I don't post much, I think this is my second time!! I am opening a studio this year and I have a question about the "cheap flooring". I went to home depot and found what I think everyone is talking about the shower pan liner, my question is did anyone find it without the writing on it? The stuff I found was gray and had the company name and some other writing on it, on both sides. Is this the right stuff?? I am looking for a cheaper option for floor!! And the roofing rubber liner, is it sticky on one side?? Thank you.
