Pva Versus Primers | Always Use A Primer When Tiling, And Not Pva

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

I was looking in tile suppliers near where i live and asked only this morning how much a bottle of primer was now of course they had the dreaded pva but also sold everbuild SBR and i was wondering if the sbr is ok as a primer as it is only £11 + vat for 5ltr bottle cos i have a large job next week that all needs priming.

Cheers

I have just read this after coating horizontal wood framing around a bath with Evostick waterproof PVA. I also went part way up the wall to cover a repaired area of lath and plaster. Should I remove it, and how?

Always said pva should be outlawed as a primer.........

Why spend a tenner on 5 litres of PVA, when you can get 5 litres of Nicobond acrylic for nearly the same price! I hate a certain builder who I have told time & time again not to use PVA.

Have been reading with interest many many posts and i have been taking note of a great many thing that i feel could / should have been included within a recent 2 week training period at an establishment highlighted in a not so encouraging light in the past on this forum. (i didn't know before i went down there is my defence!!!).

One great thing about the training was that i was introduced / recommended to check out this forum.
An example of some of the thinking where i was being linked to this topic. I raised the matter with my trainer and he vehemently rebuffed the argument against PVA and proudly declared his loyalty to the stuff and that he slaps PVA onto every surface. Something which i am quickly learning is not quite the recommended action.

Ah well, you live and you learn.

I was also told when i went on the Bal course never to use pva as it sits on the surface and doesn't inpregnate the substrate, when he showed us it just peeled off like a rubber film...nuff said eh!!!

I noticed that some of Topps adhesives (tubs) specify the use of PVA as a primer!

(sorry Gaz!) :joker:
