Had a chance to give this a go today.

Usually I scrape it, pva, put a thick coat of skim over it, flatten and let it go bone dry

Then I pva again and do your standard 2 coats of skim.


Was given advice from zombie and a few other members on here about part mixing bonding with skim as a first coat then second coating with skim



So today I got on it!

Ceiling was horrible too, thick stipple effect.

Got the first coat mixxed with bonding and went away with it, have to say it was absolutely perfect over this sort of crap, the first coat filled all the artex very well, went on flat and pulled in nicley so when I came to second coating with skim it was like skimming on board!


My advice to anyone skimming over artex is to use this method, its a dream to lay on and makes your life so much easier.

Big thanks to @zombie for his advice and anyone else who had input on the subject.

The timber down the edges of the breast?

Yes, I cut them off this afternoon and put a piece of 3x1 timber on the face then filled it with sand cement, ill skim bead it tomorrow
 
Yeah most would, including me if it was a little cash job, but I do damp proofing work as a job and this house is riddled with it so bonding on pretty much anything is a big no no haha.
 
@Royston.....your more than welcome buddy im glad that all went well...and I also appreciate the thanks!:RpS_thumbup:

that little mix will become your best friend for refurb work mate...

ps... I had a wall today which included tile addy,skim,paint,artex and a couple of chases...just glued it all up and covered it all in the magic mix let the deep areas pul in then top as normal job done...its awesome!!!:RpS_thumbsup:

How does the 50/50 mix Handle with a speedskim ??
Click to expand...

works well for a first pass mate if its on to thin it pulls the bits out of the bonding but not that its a problem as it then gets covered by the 2nd coat...

I use it most days windy with a speedskim bud as I work for a bathroom company and use it to go over bits of tile addy/exposed bricks/ paint/skim /chases just make sure I glue up well first...

its the bollox mate
 
@zombie

Cant thank you enough mate, I go over at least 3/4 artex ceailings a month, i wouldn't say I struggled with doing it with 3 coats of skim but I struggled to fit in enough sets in a day to make it look like i done enough haha.

I had this ceailing flattened and polished by 10.30 and managed to fit in a couple more sets afterwards to fill the day out.

Using the "magic mix" is going to be a life saver on cash/price jobs that I do for myself.
Cant thank you enough mate!

if you're getting 4 a month,then i would advise you buy some thistle bond-it primer.

a much better product to use than PVA


PVA is a glue your only bond is once it goes tacky,if you start in one area,buy the time you have applied the PVA it will begin to set hence loosing your bond.

if you was to get a natural draw through the room like a front door open and a window,over time with the door slamming hence causing vibration,hence the plaster breaking its bond and cracking and likely to come away from the ceiling.

i will not use PVA as a bonding agent,Thistle Bond-it is much more superior,and the product for the job.

well that was probabley the most bullshit ive read in a long time!!!

nearly 20yrs of skimming pva that I purposely let go dry before starting has never caused me any problems...dry pva re-emulsifies with we plaster...wet pva just smudges the plaster all over!!!
 
just to add if that concerned with the bond etc then realy it should be an overboard irrelevant of pva or any other solutions!!
 
I've never once had a problem using pva.

I dont skim over ot it when its wet eather, creates tiger marks and wet patches

Thistle bond has only been around for about 6 years, pva is essential to skimming. I.dont know.anyone who has used it properly have had any problems at all.
 
So do a 50 50 mix and then put on multi finish as if it's just a single coat of finish then trowel up as normal ?
 
Used 1.5 bags of multi with about 2-3 bucket trowels of bonding and plastered a ceiling, sloped ceiling under stairs and a wall. Went round a few days later and there is a crack in the ceiling with a number of coloured spots shining through the mist coat. I haven't investigated above the ceiling but any ideas of what these may be? I thought possible water leak but wondered if it was anything to do with bonding in mix. This ceiling was over blue grit and the other ceiling and wall were just PVA and they are fine.

Oh & a courteous first post hello to everyone. Long time lurker coming out of the shadows.

Looks like freckles or liver spots.
 
Could be grease or nicotine although doubtful as its under the stairs. The crack will most likely be due to movement when walking up and down the stairs
 
I think your right about the nicotine @beddy as the hall on the same floor has the same colour coming through the new paint and it hasn't been skimmed. (left as original artex) I did some more work in another room today and it stunk of ciggs. The ceiling in the pics was a bathroom though, not the stairs. The stairs and hall came out fine from the same mix.
@brandon I wouldnt fancy a 50/50 mix but a couple of bucket trowels to a bag or so of multi seemed to do the trick. It did take a while to go off but then apparently it was good to paint a couple of days later. That being said it was a hot house.
I do think I'll be using this mix on refurbs from now on. Chucked it on, flattened with eze spat, Let it go off quite a bit, 2nd coat as per usual, eze spat again. 2 wet trowels and a quick polish brought it up a treat.
Cheers @zombie & @roryston for discussing it in more detail. I've known about it for a few years but decided to try it after reading this thread.

Use a stain stop paint first then a emulsion over that, could be a number of reasons but unavoidable in most cases, I've even sugar soaped a ceiling before now and still had these come through
 
Zinsser Bulls eye is a very good sealer/ primer, a little pricey but it will defo block the stains.
 
I've found that pre gritting Artex, bonding then skimming you have trouble to getting it to pull in. Just hangs around forever. I think your better off pvaing,bonding,skimming or pre gritting day before then just skimming but then the ceiling needs to be nice and flat!

I have heard that you shouldn't really bond over Artex as it can cause it to come off any one know if this is true?
 
I've never bonded artex, usually just scrape, pva as necessary or grit and skim. That was the first time I put bonding in the mix. Heard of plenty of people doing it and they all think its good.

I'd imagine that if the artex is going to fall away with bonding on it then its going to fall away whatever you put on it.

I'm also thinking that you shouldn't need to pva a surface like artex if your putting a bonding coat over it as bonding and pva are doing the same thing; reducing suction, giving adhesion/key and giving you a surface to skim. Each to their own. What ever works though I guess.
 
Not a kitchen mate. It was a toilet and landing. They moved a wall to make it larger. Definitely nicotine I think. The same stuff came through every ceiling they painted upstairs but not downstairs. I skimmed all of downstairs but upstairs was a mix of re-skimmed and original artex.

Tomuch bonding.and it takes ages to dry.what woud british gypsun say about.this mix.maby they could do itin bags you could by at b andq hahaha
 
Luke Holmes said:
Excuse my ignorance but if using this bonding/finish mix do I still pva first? I must give this technique a try

PVA/or Primer such as blue grit as its ultimately still multifinish.

In my limited experience of this mix, it hangs around a bit but you need to flatten it off quick as it will tear or drag if you trowel it too much or too late. Lay it on and run a speedskim/eze spat over it would be my advice.

Im sold on it for refurbs etc.
