Different Size Tiling Trowels - Tile Advice

[ChiversTiling]

Was just on my mind and like to hear your views,

have all the rubi trowels 3mm 4.5mm 6mm 8mm 10mm 12mm

Obviously use trowels for small tiles for either
Mosaic for 3mm
Small ceramic 4.5m

Then my 10mm or 12mm for bigger tiles

For me it's:

6mm for walls
12mm round for tiling to ply or cement boards
15mm homemade trowel for large format

That's it.

I use a 12mm trowel for everything
walls ,floors the lot

So get a life chivers tiling

[ChiversTiling]

There's not a moan, so I an't got a clue what your going on about

What's your game this evening? Bit of trolling? Give it a rest, or to use your words, "get a life".

U should really ask your supplier about some new throwels. With large format and newer science, adhedsives and throwels have changed. It alle depends on the surface, enviroment and product. Or are you still caught in the 90's: View: https://youtu.be/pyt2US_SSBM

It's not science
Put the adhesive on the walls or floor stick the tiles

Sound like a true professional.. I've seen water leaking out of doorframes by showers, tiles showing different shades due to lack of coverage, not to mention outdoors. People with three sons and four daughters showering three times a day, times haven't changed, water damages arent a problem, science aren't a part of our proffesion and you're just right!

For me it's more a case if surface over tile format. But of course format comes into it.
I don't think you can generalise anymore. Having just done a mosaic feature 2" porcelain with my 8mm trowel.
I tend to use 6mm for ditra now rather than a 4/4.5.
10mm square or 12mm TB on floors, unless it's stone, and again depending on how good the sub is.

 

[ChiversTiling]

Yer I use 10mm or 12mm for floors as ya get a good thick bed

Walls bit different,
Obviously use 3.5mm for mosiac then all depends on the size of the tiles for me something like 600x300 I'll use 10mm or 8mm never really use my 6mm trowel

trowel sizes and notch shapes aren't that important when trying to gain full coverage on large format , adhesive companies want ever increasing deeper notches so you use more of their products , substrate flatness and back skimming the tiles and combing the adhesive the same direction all help , but its the classification of the adhesive that is far more important , most of the adhesives we use here in the uk are c2ft or c2fts1 which wont help you get the full coverage unless you mix them up so runny that it weakens their cured strength , the T part of the classification means thixotrophic or anti slump it actively holds the notch shape to stop the tiles weight compressing down or slipping if you use it on vertical surfaces , if you are looking to achieve solid bed fixing on floors use adhesive that dont have the the T rating , like PTB adhesives and similar , these readily slump under the tile and give you the coverage needed on large tiles

Would not recommend c2ft unless it's hurry up. I normally use c2teS1, as the E gives more open time.
The S is how flexible it it is. S1 can bend 2,5mm before cracking, s2 5,0mm. Full coverage on bigger tiles than 40*40 using T rating it is advised back buttering as u can see how much pressure needed.
