Re: P.v.a. Versus Primers......

Hi guys

This has probably already been covered but could you recommend a primer? to go directly onto a painted wall prior to tiling? can i use a basic builders one? and what mix would i need?

the room is a en suite with a shower cubicle in it. The walls have several layers of paint on them. I was oblivious to the need for primer - but my mate mentioned that i 'would need to PVA the walls first' so any help would be most welcome! Many thanks Dan :smilewinkgrin:

i would strip the paint off,prime with a suitable acrylic primer not pva

Hi All,
I am feeling ever so slightly gutted at the moment.
Just joined your forum and just read this thread. (God do I wish I had fund this 3 weeks ago).
Guess what?
Just spent the last 3 weekends filling and preping my bathroom walls (4) ready for tiling.
Finishing it off with 2x coats of 5:1.... PVA!
The prospect of tiles falling from walls in the not to distant future is not a vision I wish to contemplate.

Anyone got any suggestions on the best way to resolve this problem?

And please don't ask why I did this. It was on advice from a friend of a friend of a work friend (who I have subsequently just found out..... is a plasterer!).

Many thanks

I would remove the PVA mate, I presume you haven't started tiling yet. You will need to soak the PVA to soften it then scrape it off, make sure you allow the wall to dry completely before applying SBR primer. Good luck.

as above you can use an abrasive pad to losen.

Yes Plasterers use PVA, but Tilers do it properly.. :lol:.. we use Acrylic or SBR primers.. never PVA..

Thanks for the advice.
To be honest the prospect of trying to get this PVA off is not one I particularly relish.
Could I get away with covering with a thin skim of plaster and then use a primer?

Dont beat yourself up too much victic - I found this "Expert" on the internet telling prospective floor tilers it was essential to put PVA on ply before tiling.......... Yes its a Tommy's Trade Secret (lol)
