Stripping basement concrete floor and then I ran into an unknown substance


I was stripping my concrete floor in the basement as most of the paint was coming up and we did see water (not much) during last winter's thaw through some fine cracks in the concrete. after letting the stripper sit for a couple hours I scraped and then scrubbed with a hard bristle broom designed for concrete. I had originally thought the concrete was dyed red but then in some areas, the red started to come off and it became very messy/slippery. I searched google but cannot find anything that relates to the material; it is red but when scrubbing off it is almost a metallic copper colour and it sticks to everything. I am assuming this is a concrete sealer so now my plans have changed. I was originally going to strip, etch, bonding primer then paint but now I am unsure of how to proceed as I cannot confirm what the material is. Does anyone have any idea? I have attached photos of the products I am using and the floor. Any help would be greatly apprecaited.

I can't recommend coating the floor with anything since you have known water issues. Even water vapor and/or liquid water can cause most floor coatings to fail within a few years.

The goop on your finger reminds me of carpet adhesive.
