I’ve plastered my ceiling over artex with multi finish and I’ve never done it before and by the time I finished the first coat it had gone off to quick before I could put on a second coat. Is it possible to still put on a final 2nd coat if so how and if I also muck up the final coat is it possible for a professional to do a 3rd final coat or will it be to much weight for the ceiling?
First the best way to take on a artex ceiling is plenty of pva and use a thistle bonding its much thicker let it go off preferablly 24hours then come back and put your finish coat on (multifinish). Also you couldnt put a third coat on its to much weight best way to do it is either strip the ceiling or overboard it with new plasterboard
Post your job & get responses from local tradespeople. Read reviews before you decide to hire.
No you need to remove the pointed bits of the artex. Then plaster so you see no artex then use multi finish.oh don't forget to bond it after removing the snap bits
Even one coat of skim over Artex can be too heavy. To be honest (sorry it's bad news) at this point your best bet is scraping it off and skimming over the boards. Obviously check there's no asbestos in it first.
You should have uni bonded the artex first. That would have slowed down the suction process. With plastering it is all about speed that comes with experience. If you unibond over what you have done let it tack up you can lay another coat on ceiling and you will get longer to get it flat.
Did you apply 2-3 coats of PVA prior to skimming with multi finish? This process must not be missed out, as it gives you the sealed ceiling surface that you need to work with, ceilings are the hardest surfaces to plaster, if you are in doubt I would get a professional in. Steven George Cook
Put lots of pva on it mate if you get stuck let me no
Did u use pva first as u must do a couple of coats so it doesn't dry to fast but to answer your question yes you can do as many coats as you like just PVA first 1 coat 5part water 1part pva second coat 3water to1 pva
Artex always should be removed before plastering.
You need to apply a form of a pva substance first. What we use is Blue Grit, which is a branded name for plasterers grit. You use a paintbrush or roller to apply it to the artex after you have scrapped off any peaks to the artex. The drying time is still quicker than if on clean plasterboard, however you have more time with it. Also as you laying it on, if you get it as flat as possible with less lines then there isn't do much you have to go over and start chasing your tail.
