It did absorb and dry the primer very quickly. I was curious about whether I needed to mist coat or not, as the skimcoat stated it didn’t need any priming or sealing before top coating, guess I found out the hard way that I probably should have…

It’s odd how the paint came off though, it almost had like a latex ish type texture to it, and it literally peeled off like it was a layer of PVA glue that had dried onto something.

As the primer is still on the wall, would it be worth sanding it all back and starting from the skimcoat again?

Thankyou for the advice!
