Plastering over Artex that has asbestos in it

50/50 pva & water, all tho I would recommend blue grit paint on & let it dry for a day then skim over.

Always mostly recommend over boarding to.

It is possible to skim over artex by diluting PVA 1 part water/1 part PVA.
It all depends on how thick the artex is. If it is too thick it would need to be scrapped back and prepared properly for a skim coat. But if it’s been tested and it has asbestos in then this would need to be removed by a proper asbestos removal company in a safe way.
I always recommend over boarding artex ceilings when possible to get the best possible finish.
Hope that helps!
Thanks

Hi there, I too complete a lot of plastering and especially over artex, I mix pva with water 50/50 and give the ceiling a good coat allow it dry and then apply another once tacky get your self a bag of multi finish and start your mixing process but in your first coat add a couple handfuls of bonding…. It helps fill out a bit better…. Then fresh mix just multi for your second coat…. Always apply your first coat slightly thicker… you want to have pretty much covered the artex with first coat….

Hope that helps you

Do not attempt to scrap the artex. Apply a sealer coat on the ceiling. Then apply the first coat of plaster.

The best way around that is to over board the celing and then skim the plaster board.

Do a 50/50 mix of PVA and water and apply that to ceiling, wait to go tacky and then if stipple are big you Will mostly likely need to put a coat of bonding on first before skimming, if stipple are small then two thick coats of plaster should do the trick

There is a better additive then PVA! I would recommend Bluegrit to prime your ceiling.
Once ceiling is ready to plaster i would recommend to use multi-finish plaster.

You can dilute the PVA with water in a bucket and paint this all over the ceiling with a paint brush once this starts to dry skin the ceiling as normal I'd recommend a slightly stiffer mix in the first coat do cover the deep artex.

I would recommend you use blue grit it is a PVA with grit in it then leave for 24. hours
Then 2 coat plaster Over the artex
The only other way is to over board the ceiling

Mix the pva with water into a bucket large enough to fit a roller into, apply it with the roller, if it dries fairly quickly, then apply another coat,. Then you will need to float it out with a coat of bonding to cover the artex, this will tske a couple of hours to dry before finally applying the finishing coat.

The PVA can be mix with water is about 4/1, four time PVA and one time water, if the PVA is thick, if is already deluated you can paint it straight away, or Thistle Bond-It Ready mixed Plaster & bonding Agent, 10L Tub, from British Gypsum, one Tub should be enough or can cover about 45 m2, you must let it dry properly, to dry can take about between 3/8 hours summer time, if is cold between 12/24 hours, after that we can plaster it.

You should under no circumstances try to scrap it off. Or take it down your best option is to either over board and set or. Two coats of pva and plaster straight over it.

Yes can plastic over it

You can plaster over artex with asbestos but make sure they don’t scrape off any of the artex. If a bonding coat is required first do that then apply multi finish for finishing.

the appropriate asbestos removal team must remove the asbestos first, only then can any work be undertaken

You need to bond over rates first if rates is thick pattern then skim over bonding for better finish and pva on ceiling

Pva mixed with 40% water and applied directly to the artex. Allow pva to dry. Use bonding for the first coat and then two coats of multifinish plaster.

You mix PVA with water hand apply all over the area that is being plastered 2-3 times leaving to dry in between. It gives the plaster something to bond/stick to. Usually a 2:1 ratio of water:pva

Hello.

First of all, I would always highly recommend having any asbestos removed professionally, if you do have any in your house.

The advise I'm giving is for artex ceilings without asbestos in them, but the process would be the same if you were to choose to go over asbestos artex.

You'll need to use 1 part PVA and 2 parts water. Some will say 3 parts water. For a good coat, I use 2.

Mix together with a brush (roller can be used on flat surfaces but brush is better to get in the crevices of artex). Brush over the whole ceiling.

Once it's dry or tacky to touch, apply a thick coat of multi finish plaster. Then flatten the ceiling so there's no lines.
Once the ceiling is damp to touch, but not leave any finger prints.. this is the time to apply the 2nd coat of multi Finish plaster.

Once this is on, I use my refina flexi trowel to flatten the ceiling and finish it. Usually takes around 4 trowels overall.

Do not try and scrape any artex off . It is better to PVA seal it and use a bonding coat a good plaster coat

You can't use PVA best to use plasterers grip (blue grit)etc.
Or if you can it would be better to plasterboard over it wearing a P3 rated mask
Blue grit
Bonding coat or finish plaster to take out the pattern then skim over that
