Probably, personally I wouldn't use it on anything over 200x200. In fact I will, in all probability, only ever use powder stuff again.

defo powdered gear on a tile that size and always use powdered ady for porcelain ,im with Drew never use the tub gear as apart from the ones from ardex that grumps talks about,the others are not suitable as the dont contain a porcel bonding agents.

Hi all
sorry about the long post but this should explain why a cement based adhesive should be used for porcelain tiles.
Ready mixed ceramic wall tile adhesives require moisture to be lost from the adhesive in order to allow the polymer binder to dry and forma ‘FILM’ capable of bonding both to the substrate and the tile.
A High proportion of large format tiles, typically 30cm x 30cm or greater are typically porcelain and as such, by definition the tiles have a water absorption of 0.5% or less. Therefore this would slow down the hard formation between a ready mixed ceramic wall tile adhesives and a porcelain tile. If the background is also of a low porosity or is in fact impervious to moisture, the ability of the adhesive to “dry out” would be severely hampered, bearing in mind that the only rational escape route available to this moisture would be via the open grout joints. The larger the tile, the fewer the joints, thus reducing the amount of open areas where moisture may escape. For this reason, Building Adhesives Ltd would recommend the use of cementitious based adhesives as a general rule to ensure the adhesive is capable of drying and setting beneath the tiles.
hope this helps bal tas 2

totally agree...no tub addy on this size. Granfix supergrip no good for porcelain and multifix ok for porcelain mosaics or for tiling on ply as its self priming and flexible but only good 4 small areas at a time as evoporation is quick and you end up fixing to a dry film on the surface...blu tak wud prob stick better!!!! def powder if not you'll de in deep doo doo!

Having read all the posts relating to this issue, and all the doom and gloom merchants that have responded. I now appreciate that maybe this was not the best addy to use.......however the product was supplied to the customer by a reputable tile company, secondly the instructions on the product state that it can be used with porcelain and for large format tiles, there is no actual maximun size. That said when you go onto Granfix web site and download the fact sheet relating to this product it does state a maximum size of tile. Unfortunately I don't carry my laptop in my works van. So why not put this advice onto the Tub?
My main reason for contributing to this thread was to state that I had now switched to bagged addy for wall tiling....not realising the hornets nest that would ensue.

You have received nothing other than good advice on this thread, Yomper.
