Hi all. Got a new garage/outhouse built a couple of years ago, concrete floor - which was allowed to properly dry out before painting. Put on a couple of coats of floor paint. After a few months I noticed that I had a problem with water ingress near the door and, where this had happened, the paint had started to blister and break up. I duly stripped it back and repainted. I had some further issues with water ingress near the door and again had to re-do the paint in that area.
More recently though, like over the past year, the paint has started to flake and break up in areas that were never damp. Then I happened to leave the door open one drizzly and windy day and I noticed that where the drizzle had blown in, the paint was blistering badly. I then experimented by spraying water onto parts of the floor that I hadn't already scraped away lookse paint from - and the wet paint blisters within seconds - it's as if I'm spraying paint stripper onto it instead of water!

Is this just a case of poor quality paint or is there something else going on? I'm going to scrape the floor right back all over to re-treat it. To be honest this blistering thing will actually make it easier to clean it back, but I 'm wary about putting something else down if it's going to go the same way. Anyone seen this issue before? The paint used was 'No Nonsense Trade Floor paint' from Screwfix.
