My indoor walls are concrete. I've painted one room with a water-based paint. Now 12 hours later it's cracking and peeling. I think it's because two thick layers were added without proper drying in-between.
For info, prior to painting only one layer of original paint was on the wall and a primer was applied first and properly dried, so the wall was pretty much clean before the real paint job started.
What do I do now? Do I have to scrape the entire wall prior to paining again, or is there some easier solution? I'm assuming painting it over again will only make it worse.
