After a little more knowledgable advice when it comes to having some ceilings skimmed. Late 90s with the artex style finish. Had 2 plasterers round, 1 says he will pva and skim over. The other says blue grit and skim. Both have a good reputation and have come from word of mouth recommendations.

Not looking to overboard as will mean having to remove the coving, plaster ceiling roses etc. But not sure what method to go with… if it makes a difference, the artex style finish will scrape off easily, leaving a not too hard a job to get a good finish.

My plasterer always used Bluegrit on all ceilings and any surfaces where there was any doubt. It does work, so does PVA, but I think it s worth the minimal expense to use Bluegrit. That being said it s all hanging on the strength of the bond of the previous layer of paint ..

Edit: I think Artex had asbestos in it until a certain point, no? I thought the advice was always to knock the high points off if really necessary but to generally leave it undisturbed.

as said above - Febond Blue Grit - its £25 for a large tub, that should do even the biggest ceiling - it'll stabilize the artex and give the Multifinish a good key.

All PVA really does is slow down the suction.

Either works provided it’s applied and left to seal, dry and harden for 24 hours. It’s all about the preparation.

In theory at least PVA is more about controlling suction, blue grit is more about bonding.

With PVA I think people get into a habit of using it for all sorts even when it's not a great idea.

We've had 200sqm of artex covered up this year (still a couple of bedrooms left but they can wait until we next redecorate).

Our plasterer knocked off the high spots, PVA'd (or the equivalent), and then skimmed. They all look good and despite the massive temperature fluctuations this year have been (knock on wood) crack free.

Our artex was in very good condition (ie. No cracks and well adhered to the ceiling) and was that stippled effect style.

My sister had slightly more crumbly and amateur looking artex and her plastered used blue grit. Her ceilings all look good now too.

If both plasterers are well regarded, I wouldn't worry too much about the approach they recommend - one would assume that they know what they are doing and have recommended what they believe to be the best approach

Did artex skim a few years ago with pva/plaster.

I Scraped the lot myself. Never heard of blue grit tbh.

I'm in a late 90s build so after free, but I've noticed a few cracks over the years, this was more down to the construction I think as it happened in the kitchen that was replasteboarded.

Yeah, surprised the OP is suggesting it will just scrape off, but be very careful if disturbing it, and or get it tested.
