Advice on trowel choice

[quackfly]

well fellas,
Was wondering if any of you can tell me which floor trowels are used for which jobs, i thought a 10mm trowel was for floors but there are 12mm and upwards, also why does the notch shape matter, why are some trowels u notched and some v notched and some are square. its the small details like that that all help in confidence when approaching each new job. Cheers:smilewinkgrin:

Trowel notch size depends on a couple of things, evenness of floor, bigger notch = more room to play with the levels to get it right, size of tile and type. The different notch shapes are for coverage IIRC V is 25%, square is 50%, U is 75%

u-notch trowels are prefered for floors as they give more coverage therefore better adhesion especially considering it has to deal with traffic moving over it,10mm u-notch is the prefered choice but if you have a floor that is uneven then using a 12mm can be more helpful
