Tiling straight on timber or fix layer of ply?

[Wylie]

The jobs done now i have seen ply and pva used in showers and there still there years later

sounds like pure luck if they are still there check recent posts on pva i have seen jobs done with pva and would not recomend it :mad2:

This is it as you say,though seen loads of jobs done like that on ply and stirling board and pva was used on some of them that i know
Was on a job last week retiling a bathroom,a lad was removing the floor tiles from a chip board floor he had half the floor done they where well down,of course i had the floor replaced with 18mm ply

Just because pva and ply was used..this dose not say it is the correct prep/method...

And the old saying i have had no problems isn't to say nothing has gone wrong...it just means you have not been called back...:smilewinkgrin:...

PVA has no place within the tiling industry...

I liken it to drink driving, you might not crash, or get caught everytime, but one day.............

And... no offence intended to the PVA "crew", but if you do this, like a drink-driver you're a blinkin' wally who should know better!

Well well

You say PVA has no place in tilling trade.

Why did I hear ever since that PVA should be used on walls and especialy ply when tilling?(to seal it)
When I was learning from old trades man he always said to seal walls or ply with PVA.
Even when I was working in refurbishment company.
Even friend tiler told me to use it.
And you hear it even in the shops often.

It seems to me that PVA nicely penetrates all dust on the surface of walls and make addhesive stick better rather than just tile staight on dusty wall.
I feel it is like plastering. Have you ever done plastering on dusty wall or existing old plaster without pva? It would just peal of (most likey).

And with ply I was told many times that it seals the top of the wood so it do not soak in water.

I was using PVA for years when in emploiment and never hear not to use it.
now selfemploied I do not know reason why I should not use it. Never heard about no problems with it.

PLEASE explain to me why is it so bad and what would you use?

I will be happy to learn som.. new

people just say I hope you did not use this and that but they never say why or what they would do. Dont make people ask just show what you got.
