Which trowel for 50mm travertine mosaic

[matthew_uk_666]

I'm new to tiling and about to tile my wet room floor so need a little advice.

I'll be putting down 8mm thick sheets of 50mm x 50mm travertine mosaic on to a floor that has been tanked with tilesafe using Keraquick (with latex).

What trowel would you favour for this ?

Either 4.5 or a 6mm trowel any larger and the adhesive will come through

I usually use a 6mm trowel when fixing 50x50 Trav mosaic in my wet rooms. May be ok with 4mm though, depends on how smooth the substrate is and how good the back of the mosaic is

I would go with a 6mm and pat them down with a grout float...

 

[prceramics]

as above 6mm

 

[thompsonbrown]

Same as everyone else 6mm

 

[AliGage]

thickness of stone will allow a 6mm trowel.
In other words. As above

Thanks all for your help, better to ask than screw it up

Definitely go for 6mm
