Six weeks ago I finally got my dirt floor covered with concrete. And I thought everything was going to get better, but it hasn’t.
The pad was poured over a plastic vapor barrier with a steel reinforcing grid. The concrete had way too much water in it and it took until 4:30 am for it t set up and finished with a power trowel. The temperature was around 50*F.
A week later it looked OK. I left it alone for five weeks so it would completely cure and dry and I could paint it with epoxy paint. Now I’m ready to paint and I a lighter color, but full of almost black patches. What can this be? I’m worried if the epoxy will adhere properly.
I have a rat problem and vacuumed up the poop before taking the pictures. I have been going through a lot of poison, but they seem to thrive on it. Is there any chance it could be from rat pee? If so what do I need to do before I get paint it. Unfortunately, there is no drain, so large amounts of water will be difficult to use.
Any ideas
