Deffo not tubbed addy, Must be powder stuff. SPF will be fine, 16hrs before grouting though, and shower must be left 2 weeks after grouting (says BAL if you use their stuff).

Absolute max size tiles for tubbed stuff is 300x300mm in my opinion. Would still use powder stuff now though. I find it quicker and easier to work with. Tubbed stuff is quite thick and heavy to trowel.

I agree

A tubbed adhesive would stick big ceramics. The problem is the air passing through the open joint to aid the curing process needs more time to get to the centre of a tile the bigger it is. If you remove your spacers and tile stays on the wall, the adhesive in the centre may still be wet reducing the set coverage. You well may think all addy has set, so you grout. This in effect is like placing the lid back on the tub,the addy in the middle is still wet. This is why we will recommend cement based addy for large format, even ceramic ones. Hope this helps explain it .....Gaz

Even if tubbed addy did eventually fully dry,i'm not saying it would btw, the chances of getting through the entire job without needing more than a 3mm bed are pretty slim.

Bagged is better to work with too.

Just finishing of the second of 2 bathrooms which I have tiled with 600 x 300 porcelain. Customer supplied adhesive etc. The first bathroom I used the supplied addy.....Granfix tubbed as recommended by the tile shop. What a pain to work with.....It was heavy, difficult to work with despite being stirred and I had to leave it over the weekend to dry before I could grout. I told the customer that on the second bathroom I would use bagged addy. I used BAL and found that it was very easy to work with and dried overnight. Converted now never to use tubbed addy.

You should not have used any tubbed addy for that size of porcelain, mate.
I would never use tubbed at all for porc, but Granfix do say that Multifix is suitable for porc' but only up to 300x300.
WHat shop reccomended that addy?

I don't want to worry you, mate. but if you have used SuperGrip

you could have major problems ahead of you.
Even if you have used Multifix

Granfix will not have to honour their gaurantee.
Good luck.

Ardex D20 and D30 as well as BAL white star can be used to fix porcelain as long as the substrate is porous and the tiles aren't too big!

I imagine that 300x300 is their max too then?
