Square notched trowels on floors

[RDTiling]

Over the last few weeks I've been called out to replace singular floor tiles in a few bathrooms and kitchens.

From looking at the dried adhesive patterns, after the loose/cracked tile was removed, they look as though they have been laid using a square notched trowel dagger than a u notched trowel.

It got me thinking, was the original trowel type used part of the reason as to why I was called, or is it ok to use square notched trowels on a floor?

Usually a u notched trowel is used to give full adhesive coverage, but if the tile was back buttered and then laid using a suitable square notched trowel then I would think full coverage would be achieved?

Yes, you are right in thinking that. Square notch is absolutely fine on floor. I rarely ever use u notch nowadays

Thanks Geoff.

To get the replacement tiles level with the surrounding tiles I ended up using either a 10mm or 12mm square notched trowel.

I actually found it much easier to lay them using the square notched trowel.....particularly when I lifted out the damaged tile and five others around it came loose and lifted up too!
