i use 13 mm trowel then pick them up and at least notch the floor again 😛ete

 

[hillhead]

If the floor is nice and level a 10mm or 12 will do well,13mm if its bad or use different depths if levels are off,i laid 34m of 600x600 polished porcelain in the middle of this week with a 10mm,good floor.

10-12mm trowel 3mm is the maximum I'd go.

can you use a round notch trowel, solid bed i think its called. i read that this is what you use for floors. maybe i'm wrong.

yes ross thats a good trowel for large format tiles i lay about 400 mts of 600 x 600 a week they have to be laid with a solid bed never been able to do that even with a 13 mm trowel, are you guys skimming the backs ? as i use PTB 😛ete

hi

20mm notch,or 10mm but do a back skim,,

If your wanting a solid bed coverage, try a 15 - 20mm round notch trowel and lightly float the tile away about 10 mm diagonally away from the rib then bring back to the grout joint you require.

I'd use a euro notch trowel.

I'd use a euro notch trowel.

They look nearly as good a my Platinum trowel...:lol:

Large Format Large Trowel 20mm PTB and back butter with 600 x 600 to ensure 100% coverage. If they are porcelain make sure the addy has got porcelbond in. If you are tiling on to concrete clean it and prime first.

Also PTB usually does away with the need to back butter but check periodically for coverage ............The key is in the prep work...flat floors make tiling easier.....

 

[ross lewiss]

hi
what is the maximum gap under a straight edge you can have over 2meters in order to tile. is it normally 2-3mm or can it be more.
thanks, ross

[ross lewiss]

thanks, ross

 

[Perry]

Ross its Dave i was getting at Dave's a Bal man I use PCI just a Little banter between ourselves nothing to do with you hope i didn't offend you always help newbs if i can regards Pete

 

[ross lewiss]

just found out today that there is no point using a 10mm, 12mm, 13mm square notched trowel on 60cm x 60cm. it should be a solid bed radius trowel. anything else is incorrect and this came from bal. coverage and compression is the reasons.

 

[Perry]

and bal would know lol i am not so sure

 

[ross lewiss]

well i am sure a multi million pound company who test and produce would know slightly more than a self taught merchant like your good self pjc hmmmm let me think, bal or 1, 109 post pete lol lol lol there you go , i sound like you now..i am sure you know your stuff pete, but dont fall into the trap of all the old timers who think they know it all. science over opinion every time!!

i would still use 10mm or 12mm notched trowel. never had any problems with these trowels and laid 1000's of metres. used ardex 7001 today on 6oox300 with 8mm trowel and got excellent coverage.

 

[ross lewiss]

if you are laying 600x 300 tiles with an 8mm trowel, then you should not be laying tiles for a living. you need to get re trained and i mean that in a constructive way not insulting..

 

[wayne]

check out the pdf file on ardex 7001 which tells you to use 8mm notched trowel before you tell me i should give up tiling. it isnt me starting threads on how to spread adhesive or how to mark lines on floors if you are on your own. if you are a newbie fair do's but dont come on here telling people they shouldnt be tiling if you dont know what you are talking about.

 

[sWe]

If the tiles are flat enough, and the substrate is flat enough, there is nothing wrong with using 8mm square notched on 600x300mm tiles. Really. It's about the coverage/contact between the tiles and the substrate. If it's full or very near full with an 8mm trowel, there is little sense in using a trowel with larger notches.

 

[ross lewiss]

the fact is i am new, and the other fact is you are using the wrong trowel! sorry that a newbie has educated you. i would rather have a little bit of knowledge and know its all right, as opposed to having a lifetime full of knowledge and most of its wrong. sorry to have upset you wayne...

 

[ross lewiss]

hi swe, i am a massive fan of yours and you know that, but british standards dont agree with your statement. 8mm sorry, wasting your time..

 

[wayne]

not upset mate you just need to know different companies use different methods. you better ring ardex and educate them as well as they have printed it on their adhesives. i dont claim to know everything you learn new things every day at work.
