Q:

I have a basement floor that has been painted at least once, and probably with an oil base.  The current topcoat was a latex paint. 

In preparing to paint the floor with a concrete water-based acrylic floor coating, we are seeing the current floor coating bubble and chip off. This is from damp mopping and we plan to use a TSP cleaner.   Do we need to completely sand all the paint off?  Do we need to scrape the floor and sand it?  Is there a sealer for the floor that will seal the old paint so it won't bubble and then chip and become the base for our new paint? 

The basement is unfinished and I'm simply trying to update the paint on the walls and floors to freshen everything.
