Pva trouble?

[Mac82]

Hi just wondered if anyone else has had trouble with plaster peeling off a pva,d wall, ceiling I uni-bonded the day before so sure it's not because it's still wet? Really annoying!!

 

[thebigfella]

Was you using board finish or multi ?

 

[gdplastering]

I was using multi pal it was just peeling off in a couple of spots whenever I went over it so annoying!

 

[thebigfella]

I've had it a couple of times last week small areas just flattened it with plastic trowel and left it as long as I could before going over it again

Was it on distemper?

no, November.

Maybe frost got to it in tub over night in the van?

 

[leebo02]

i always give it a coat the day before then give it a coat before setting and wait for this coat to go tacky before setting

Cheers for that pal I've not tried tha plastic yet.

I always mix a bit of sand with pva and roll on the day before:RpS_biggrin:

Do people still do that like, put PVA on the wall and wait for it to go tacky before you hit it, all nonsense to me.

didny recognize Flynny with the sunglasses lol

 

[leebo02]

i still do it this way ,, never had a problem with setting coming away

 

[Skimble]

By peeling off do you mean chicken skins? Normally occurs when pva is too wet and/or not mixed well enough.

colder times of year I normally make pva mix a
bit more watery so it tacks quicker.

every wall needs a different approch when you apply pva. some need two coats some just a light coat.
we pva as soon as we arrive on the contract,open the windows to try to get the pva to dry.
i do not like the pva to be to wet when i skim, if it is i would put a sponge over it to take some off.

If your going over d̶i̶s̶t̶e̶ limewash you'll need stabilising solution first, as pva wont stick to the dusty surface & will peel :RpS_wink:

You could patent that idea and call it Muchbetterercontact or such like. :RpS_cool:

 

[faithful]

Are you mixing it too thick ? Is it peeling ?

 

[johniosaif]

Possibly not the pva but perhaps glue from old paper on the wall or dust or grease or old distemper paint(not tiny tempah)

for or the guys who use stabiliser ,how long do you leave it before you pva, I have never used it myself

 

[Nisus]

The water based stabilising solution is dry in 20-30mins, depending on temps could be quicker could be longer.

No never had a problem.

its great for overskimming!brilliant key but the walls do take a long time to set but if you got the runs you can easily do 3 to 4 bag sets :RpS_thumbsup:

I only skim over hard PVA these daysd and tend not to have any problems... if I do get problems its normally due to the something else on the wall Or I am just shite
