Tile adhesive?

[ray99]

Can I ask some advise about tile adhesive please.
Tiles are ceramic, 250 x 200mm and each one weighs about 600g. Wall is mainly skimmed plasterboard with some bare bits where the old tile adhesive pulled the plaster off.
I had some Unibond fix and grout ready mix from B&Q but took that back after reading in the sticky that was cr*p and got some Mapei fast set adhesive (powdered) from B&Q. However I have since read that although Mapei was recommended buying it from B&Q was not.
I am now somewhat confused as to whether or not this is suitable.
Can someone advise please?
Thanks for your time. Raymond.

I make that 12kg/sqm & even adding a max 4kg/sqm for adhesive will still put you below the limit of 20kg/sqm. You need to fill the damaged areas before tiling, easiest way is to use powder adhesive just before you tile. You must always prime plaster & plasterboard with an acrylic primer when using powder adhesive to prevent a possible reaction between the cement in the addy & Gypsum in the plaster. Tank any wet areas.

Wise move.

B&Q started selling what was (is) purported to be Mapei some time ago but after checking the stuff out for someone else (I use BAL), I became suspicious as the packaging & product names were completely different to the trade stuff, this link should explain how the story progressed;

My guess is that it’s a coalition attempt between the two to launch a well know trade brand name into the DIY market & give a credible alternative to the current crap they offer; personally I think it’s a bit sneaky to prostitute a respected brand name in that way & am slightly at a loss to understand why Mapei would do it. Weather it’s any good I can’t say as I’ve never used it; budget powder addy is probably a safer bet than tub mix & fix & grout products which border on being not fit for purpose but personally I would never use or recommend DIY tiling products anyway.

Thanks for clearing that up.
I have found acrylic primer here if this is the right stuff.

but not having any joy with the tanking stuff. Will try Travis Perkins tomorrow.

Your looking in the wrong places; stop searching the DIY sheds & the major BM’s, the majority certainly won’t be of much use when it comes to decent tiling products; you need to be seeking out you local trade tile outlets (even Topps at a push but be prepared to haggle) or on-line.

This is the sort of primer you should be using;

or others of the same ilk if you get my drift!

There is a Screwfix newly opened just along from my work. I'll call in tomorrow.
Thanks for that Richard.
