I honestly can't see why you would need to back-skim!?! Surely if you are floating the tile into the addy it'll go into the voids too? I know when i've layed a tile, then pulled it up, the whole tile had adhesive on; it doesn't just sit on the ridges...

as whitebeam mentioned beanz, it's when the biscuit is profiled, it fills out the profiles and makes sure you get total contact

Thanks for all your input.

As its a shower room the floor will be getting wet regularly, so from your info I will need a solid bed under the 300x300 tiles going on the floor. I will get a solid bed trowel.

Now with the 600x300 wall tiles I take it I will be ok with a 10mm square notch trowel with adhesive only on the wall, no back buttering on the tile. Correct? If it makes any difference there is a sort of profiling of small squares on the back of the tile. What I am trying to say is that its not smooth!

Thanks very much for your help. Si

I would probably use a bigger trowel if the walls arnt to flat but would back skim the tiles to fill the profile

Pete, do you mean you use a 13mm square for floors? What would you use if your after 100% cover on walls?

Depends on the tiles i use 13mm on the walls with 600x600 that what i tile most of the time 😛ete

I'd back skim them Si

Thank you all for your input. Very much appreciated!

The walls have been skimmed, lovely and flat so no excuses!

So 10mm square notch to spread on the wall should be ok, and then back skim the back of the tiles just to fill the profile. Is that just to build the sunken areas level with the rest, or should the skim be over the back of the whole tile?

Sorry to ask more, but when putting the big tile on the wall how much pressure should I put on it to bed it in. If spreading 10mm on the walls, should this be pushed down to about 5mm or more? I don't need a rubber hammer for it do I !!!!

Thanks for your time and help. Si

Just to fill the whole of the tile profile which should give more a solid bed behind the tile, check the tile by putting one on and pushing and perhaps sliding slightly to one side and then taking off to give some idea how much coveridge there is on the tile.
