Prep, adhesive and grout advice for bathroom

[Craig001]

Hi all,

Just wondered if anyone could offer some advice to me ahead of me tiling our bathroom at the weekend.
I have a limited bit of experience in that I used to fit bathrooms although the majority of tiling was usually done by someone else.

I basically have a bathroom with 3 walls that are plastered over block work and one stud wall that will be boarded in aquapanel board.
At present there is half height tiling and wallpaper on the walls.

I would just like to know how you pros would go about preparation of the surfaces and what adhesive and grout you would use, I have read so many posts re adhesives that I am more confused than when I first started looking!
The tiles that i am using are a mixture of white 600 x 200s and a raised split surfaced porcelain tile up the middle of one wall (Petra Negro 200 x 200mm) as a feature which i think will need a small joint size to look right, maybe 1mm?? I guess this will make them a real pain to grout though??
My worry is that if I don't get the grout into the joints properly that it will end up falling out and I will have a disaster on my hands.
Any advice on what products would be best suited and any for-see able problems would be greatly appreciated!

Thanks in advance

I know your Petra Negro is porcelain but what is your 600 x 200 & what do you mean by mixed?

I personally wouldn't even attempt to grout the split face tiles and as such would only use on a feature wall in a dry area.
Use a single part flexible bagged adhesive and a flexible grout and you won't go wrong.
Be sure to use an acrylic based primer on plaster surfaces.
