how much adhesive-am i being ripped off?

[tiler tom]

Go with Dave and Fred 20kg covers approx 5 sq m. So thats 4 bags. That is with a 10 mm trowel. Remember size of tile is irrelevant just floor coverage.

Each to their own but size of tile determines which trowel I would use so that would definetly have a bearing on adhesive coverage.

I totally agree with DS on this issue....Gaz

same here,i agree with DS aswell,every job is different and so you cant gauge how far you will get out a 20kg bag as it depends how flat the floor is and if its running off you will use more adhesive.

I have a 15mm solid bed round notch that I use for LF Tiles. It eats addy and caught me out big time the first time I used it. Brian C also very valid point IMO about floors being uneven. Most floors of late i have laid are LF tiles and some are getting extreme. The tiler is not ripping you off just not wanting to be left out of pocket for giving you as level a floor as he/she can....IMO of course.
