Got a medium sized job on using 250 x 400 porcelain on skimmed plasterboard.
Have used tubbed or powdered on previous jobs, depending on the m2, but just like to know what the concensus is.

Tubbed gear isn't suitable, mainly 'cos your tile is porcelain, and it's bigger than your average tile. Single part flexible or mosaicfix is the way to go...........Gaz

I second that.

Powdered here too...

Deffo powdered......

Powdwer as well

Powder, quality minimum C2T acc. to BS EN 12004

Why not C1T Pawelzik?

Has anyone used Palace SuperGrip Acrylic Tub Adhesive? Its technical data says it can fix all types of wall tile (porcelain,stone,etc), even the largest and heaviest. It does not say what the limitations are tho.

Taken from Palce website PDF

"When fixing porcelain tiles the drying time of the adhesive will be significantly extended therefore grouting should be
delayed until the adhesive is fully dry, additionally any porcelain tiles of size 300mm x 300mm or greater should ideally be fixed using a
cement based adhesive. Additionally, all types of large format ceramic tile, i.e. those with dimensions of 300mm x 400mm or more, will also
significantly prolong the drying time of this adhesive and a cement based alternative is strongly recommended in such circumstances."

Thanks Sir, can you send me the link for that technical data, i cant seem to find what you say, on the site im on.

Because its porcelain. For these I recommand addy with C2 adhesive force minimum.

Just an add on to this thread. I am going to be starting a job soon involving 300 x 600 ceramic tiles onto plasterboard. Never tiled a wall with this size before but will be using a powder based adhesive. My local supplier stocks bal adhesives. They have a C1 tile powder adhesive called CTF3, which i am thinking will do the job after the plasterboard is primed with acrylic primer. Has anyone used this type of adhesive before, good? bad? or other recommendations?

If they are ceramic it will be fine....but for added security i would use a flexi one maybe bal spf or mapei adesliex p9...

BAL Mosaicfix is ideal too...

It is...but it's a fortune..lol lol..

Don't cry Russ but the Mapei Adeslix p9 is only about £10 a bag...20kg..

Cheers lads, this will be my first powder based adhesive used on plasterboard. Only ever used rapid set adhesive on floors, but this has more open time, which i think is ideal for wall tiling.

The 3 i mentioned all have about 5hrs pot life and about 16hr set time.....

Dave I can get Mosaic fix for about the same price as white SPF and cheaper than White Rapidset flexy.

Mapei...bah humbug
