Hi... and welcome..

1: Use a slow flexible set cement based adhesive if not a quick worker.
2: hard to sat without seeing the room layout..
3: Silicone..
4: Sounds ok to me
5: 3mm min..

Hope that helps.

Try a 10 mm square notched trowel. It gives a deeper bed on rough concrete floors and can help take out small dips in the floor.
A tiler friend once said to me try 1 u won't go back to a half moon trowel. Half moon are good on flat floors. Give it a try smg let me know how u get on.

I would go with a half moon trowel myself as these are designed to give a 100% coverage of adhesive, also I would back butter each tile before laying them into the adhesive bed.

Apart from that Dave has covered everything I think.

With Dave and Rich on this one, round notch for all my floors. Tip top advice.

Just to add, if the floor is uneven and you think that you would struggle to get the tiles flat and even with a half moon trowel then you are much better sorting the substrate out before you begin tiling, substrate preparation is soooo important.

half moon on floor for that size tile as you have to get 100% coverage.

Thanks everyone for replies

I would even go up to a 13mm trowel for a tile that size, even if your floor is perfect!
