is PVA primer ok?

Hi guys,

I am about to tile my shower and have a question.

I have fitted mositure resistant plasterboards and I have brought "unibond tile on walls" to stick the tiles.

The packet says I should prime the walls using a mix of 1 part PVA to 5 parts water, but I read many sites like the one linked below saying that using PVA is bad as it can reactivate if it gets wet and the tiles can fall off.

Should I just follow the manufacturers advice?
Can I use another primer like a BAL primer with unibond tile adhesive?

Not sure what to do, people seem to have different opinions :S.

Thanks in advance

Use an acrylic primer not pva.Always tank in a shower.
