Every other ceiling i am doing at minute seems to be artex to flat. Always recommend taking off as many high points as poss then because of painted finish always use bonding agent nowadays as pva just hangs around for ages. Wickes is good stuff but really like using Thistle bond it on ceilings and although can take 24hrs to set is worth wait in my opinion. Then lay first coat on and flatten out as much as poss. Let this tighten up before doing normal 2 coat skim on top. I found that it helps to let first coat stiffen up as much as you can get away with before going onto it with other 2 to prevent any ridges/bumps from appearing. Hope this helps. Just finished 30x12 artex ceiling last week so got plenty of practise. Hardest bit tbh is feathering joints between each section when doing large area.
I can honestly say I take pride in my artex to flat I am always doing them.
I use a hamilton scraper...rake it back real messy... get the labourer to do it
Then I use wickes bonding agent, 2 hours is ok if your not raking the artex back but because you are scraping it back the agent sucks in quicker and normally i rake it back first then go over it with agent then by the time I have unloaded the van with skimming gear its ready to start slapping it on.
I do however sometimes do a 3 coat skim, not the gold trowel way but I still sometimes give them 3 coats.... this also looks wicked on the invoice and people pay me more for doing it...lol
If you notice any high spots when starting to skim just give a scrape or t**t it with a hammer...lol
Are you crazy of course you can skim artex, sometimes you get probs but nothing that cant be rectified quickly. thats only in my opinion, If the artex is bad i bond it first and bonding sticks like SH!T to a blanket. (this is only my opinion)
HELLO mate the best thing to use on artex ceilings is to unibond the ceiling first dosnt matter about the big bits unless they are really big but go and buy a couple of bags of bondng coat fron builders or b and q . Aply the bonding coat to the ceiling first , that will get rid of the artex then let that go off ,, then scratch it up with a scratching comb then aply your first coat of plaster let tac up then put your lay down coat on and i promise you now if you are as good as me then you will get it perfect L.O.L
REMEMBER if the ceiling is old or should i say if the artex is old say 20 yrs or older the chances are that the artex is of the old type of powder and the chances are that once you put unibond or even just water onto it then your plaster etc your in trouble .
EXAMPLE ... if you run your fingers over the artex and tou get dust on your fingers that is the old type of artex . Its no good you will have to eighther scrape all the artex off (easy once wet ) or you will have to over board
If wen rubbing fingers over artex and it sticks in your fingers depending how hard you press and it feels solid then you know it is of new artex
If it is old artex and you skim that your in trouble cos it will proberly have distempa in it .
Yes i know you may think of distempa as being assoscated with dogs but its true
you do get distempa in old artex
SORRY FOR KEEPING YOU SO LONG BUT I TRY TO HELP AS MANY PEOPLE AS I CAN
I normally scrape off the high points of the artex with an old cheap trowel untill its as flat as i can get it.
Then make sure that the artex has not been aplied on top of lining paper :
I try not to bond out ceilings, as it adds a helluva lot of weight to a ceiling that someone else has artexed on.
If it needs bonded out, then i normally either rip it down and put up a new ceiling, or just lower the ceiling.
But if its just a fine stipple or something, i scrape it down as flat as i can get it, then PVA it a couple o times.
Then hit it with Multi.
Sometimes after i have taken the lines out the second coat, and flattened it a bit, i will mix a little bit on the hawk to fill in any pits etc....This can make a world of difference.
If the artex has been put on top of lining paper, then either re new the ceiling (Gyproc) or you might get away with just plastering it, but with no gaurentee
do pretty much the same as that but i tell customer that i wont go over it if there is sign of backing paper and recommend they use wallpaper steamer as this strips it pretty well!
Stopped using pva on artex now since using bonding agents as spent ages hanging around with pva whereas thistle is good if doing ceiling following day, with wickes once on can do anything else you need to do (couple of walls etc) and go straight onto it as only takes couple of hrs to dry so you keep working and earning!
Hello there the names Craig i'm from Middlesbrough. Just bin reading through the convo bout skimming ova artex. Remember that after all this discussion bout lining paper, two coats, three coats, bonding agents n pva that artex is not a weight bearing product. Its not happened to me yet (fingers crossed) but I do know plasterers that have had full ceilings come down on them bcos the artex cant hold the extra weight. Its a good way of putting a bit of extra cash in your pocket if you explain this to the customer as you can charge mor for ova boarding.
Same as Wickes Bonding agent really. It's an acrylic based gloop (as opposed to PVA which erm isn't) and it has a gritty aggregate in it. The gloop dries (thistle 24 hours and wickes 3-4hrs) and seals the suction creating an acryllic barrier and the grit provides the dog's b******s of a key.
Hi Hve done quite a few Artex covers, and what you said is spot on....only thing just be prepared to do 2-3 skims to get that perfect finish. I think if you have other rooms to do, set out to do 3 fast skims, rotating rooms, works out a bit quicker and much better finish
