Why'd this happen.

Was doing this job recently and didn't have time for extras and got another plasterer to come in and skim the walls and ceiling for the client. Ended up there was another 2 smaller walls in bedroom needing skimmed aswell but he couldn't do them. He left an excellent finish but ended up getting another fella in for the 2 smaller walls. Prepped with thistle bond, 2days later threw Bonding on to straighten wall(or so I thought) then skimmed next day or 2.

In one room, the wall became boast. The Bonding came off the thistle bond and the skim came of the bond. In the other room when I came back to look, noticed the joiner had to scribe the architrave because of the wall(see pics).

Thinking back now, when I was working in the house at the same time, I noticed the other fell throw on 2 heavy coats and was wondering WTF is he at because all it needed was the normal first coat then wee skim over for second coat. As a result, he caused the joiners to have to scribe this archi because the corners where to thick and a bow in the skim. Also one side was so bad it was an eye sore. I got the first plasterer back to sort it out but he also noticed even thou the skim wasn't boast as in hallow, he was able to scrape the skim of the bonding.


What I want to know is, why'd the skim and bonding didn't bond to the thistle bond and bonding. Was it a case of bad Bonding or the 2nd plasterer just made a balls of it.

Don.t f**k**g no and dont f**k**g care
 
Lurpack thistle bond it or gyprime is the only two products bg recommend for skimming mate obviously they make it so gonna only recommend that mate , did the guy stir the bond it before applying it maybe that was issue , might just of been to thick for it , did he key up the bonding coat for the skim to key to as well ? Next day could also of been to dry maybe ?

Also brick dust ? Was there work going on around in there after he applied the bond it ? Stupid as might sound I seen skim delaminate after primer applied then skim went on next day and it fell off
 
Thistle bond it I have never used, though I thought it was the top dog of grits. Call bg.

Only used pva and never had an issue every. Blue grit very occasionally.

That thistle bond it is mega money!? And I've seen it fail many times on jobs. Don't understand why people use it on basic over skims?

Expensive as f**k

Ballache to apply

Fails regularly

Not complicated is it lol. Heres why pva fails

You didn't scrape wall or ceiling PROPERLY. Lazy c**t.

You use cheap s**t pva and you add 30 part water to 1 pva. Cheap c**t.

What I've always done and i skim ceilings some of you pussies would probably double board as scared shitless

Scrape properly. Decent pva mixed about 50/50 ish. Nice generous coat. Let it dry and skim.

If pva goes straight in give it another coat, if it stays white for a little bit that's perfect.

I've also never skimmed onto 'tacky'
Pva. I pva day before or same day makes no difference but it's always dry. First thing i do on a job.

I cant agree strongly enough.
Piss Poor Preparation = Piss Poor Performance

This is everbuild pva,,,, note do not use in areas of constant dampness, which can be bathrooms with no fan, windows shut. Other areas, some other pvas will no doubt say same if you find spec.

Do not use for sticking plastics or where both sur-
faces are non-porous.

▪ Do not use for sealing garage floors.
When used as a wood adhesive, do not use on load
bearing applications (chairs/beds etc) or in areas of

▪ Do not use below 10°C.
It is always the user’s responsibility to determine
suitability of use. If in doubt contact technical
 
I've always been a pva man but was hearing good reports on the thistle bond so started using it on some jobs. I was the one that said to the client to get it in and labourer rolled it on before the plasterer came in to skim it a day or two later.

If it was the thistle bond that failed, whats baffling me is why did the skim come loose of the bonding on one wall and the bonding bonded to the TB
