Try a Mr. Clean Magic Eraser...these work for me on everything! We removed permanent marker from a white latex painted wall! :O)
If it is vinyl tile and it's latex paint, rubbing alcohol will remove it. If it is a ceramic or porcelain tile, you can carefully scrape it off or if it is also latex paint, the same thing,,,alcohol will remove it.
I found out that Rubbing alcohol will remove dried latex paint on hard wood floors.
You can remove latex paint with denatured alcohol. (You should be able to find it in a hardware store.) I do not know how denatured alcohol would react on cowhide. I would suggest testing a very small spot to check the results before proceeding with paint removal.
i have dried white latex paint on car seat. what do i do to remove it?
Since most stains are oil based, proper cleanup would be mineral spirits aka paint thinner. Denatured alcohol will clean latex based paints.
how can you remove walnut stains from your car paint with out hurting your paint on your car
If I was going to repaint this, then I'd remove both the latex and the old oil base with a chemical stripper. Then re-prime it and paint.
If it's not synthetic latex, go to the store and look for a product called Goo Gone Power spray... It disolves latex paint, so I assume it will take the latex off of the carpet backing as well.
Acetone is usually used to test if a paint is alkyd or latex, though rubbing alcohol will work as well. Use a Q-tip soaked in either acetone or rubbing alcohol on a surface painted by the paint. If it comes off, it's latex.
You can try using denatured alcohol if it was latex paint. But it is probably cheaper and easier to just replace the vinyl cove base.

Possibly if it's latex paint.
