I've artexed my ceilings and have had problems with it peeling in all rooms. I think this was because I didn't allow it to dry properly most of the time (the box says wait 7-8 days before painting) and when I ran paint over it with the roller, it disturbed the drying artex and caused it to bubble (this was the artex itself bubbling and not just the paint). Then, other times, the paint itself bubbled. I've gathered that the second problem of the paint bubbling was caused by failure to use a mist coat first and simply putting on a normal coat that got the water sucked out of it into the artex, thereby drying too fast.
Anyway, all that is history ... this time I've followed the instructions and allowed the artex to dry thoroughly before painting with two thin mist coats followed by 3 full coats (I used B&Q Colours Brilliant White Matte Emulsion for this and the ceiling just wouldn't go white, hence the multiple coats). Anyway, on one patch, the paint has cracked and bubbled and I can't understand why. I don't think this is a vinyl paint (would that matter?).

I tried dabbing paint back into the patch but it just cracked again at the ends. So, I've now attempted to seal it using Zinsser BIN, which is why the patch appears darkened (BIN is a yellowy-white because of the shellac content). I'm then planning to dab on successive coats of the remaining B&Q Colours Brilliant White Matte to blend it in.
***Is this a good idea or a dumb one?***
I now also have a tub of Dulux Trade Supermatte which I'm planning to use on the ceiling in the other room. Should I expect better results with that?
Anyway, I gather from various internet sources that the best thing for the next room is:
1. artex
2. 8 days later do 1-2 mist coats with thinned supermatte
3. do a final coat with supermatt
But since mist coats have still resulted in problems, I was thinking of:
1. artex
2. 8 days later seal whole ceiling with Zinsser Bin instead of mist coats
3. do a final coat with supermatt
Thoughts?
Thanks a lot for any answers.
