Wall and floor tiles - adhesive amount to use

[figurinitout]

Hello all. Am tiling a bathroom with these 900x150 tiles. Will be using them on the floor and to a wall height of 1.2m. Haven't tiled with such a shaped tile before (long and thin) and am struggling to figure out the correct amount of adhesive (and appropriate trowel) to use for them on both the walls and floor.

Will be using a decent S2 adhesive for the floor as it'll be covering UFH. Not so concerned for walls - may save a few quid and use an S1 for those instead.

Floor is cement board covered with UFH decoupling mat and walls are Jackoboard panels, all pretty level.

Thanks in advance for any advice.

Personally, I’d go for an 8mm notch on the walls. That length:height ratio for the tile dimensions lends itself perfectly to a brick/staggered bond - the downside is they’ll highlight any lippage, so check your wall throughly first for high/low spots.
On the floor I’d use the biggest PLASTIC notch trowel you can find, probably 12mm. With 4mm spacers.

For those 900x150 tiles, a 10mm notch trowel should work well for both walls and floors. Use an S2 adhesive for the floor (especially over UFH) and an S1 should be fine for the walls. Back buttering the tiles will help with coverage. Since your surfaces are level, you shouldn’t have many issues—just keep an eye on lippage with those long tiles. Good luck!

Thanks guys. Am guessing the plastic trowel was in relation to not nicking the UFH cable as the addy is laid down?

Will be using the spinner spacers to reduce lippage as I figured that may be a concern with that tile size. Was shocked to see such a product even exists - so much more on the market than when I did my last bathroom just 5 years ago.

A wee hint before you start - take the tiles in pairs and put them back to back to check for daylight between.
I can guarantee you’ll find 1 or 2 heavily bowed tiles in every dozen; best to know which ones they are before you press them in !
