Adhesive spread direction

[paulphur]

Laying 120 x 20 plank porcelain, should i spread in direction of length so in 120 cm direction or across tile so in 20 cm direction. Would the latter give better coverage?

 

[Rookery]

Apart from a restricted reach I don't think it matters though I do make an effort to comb out in the same direction.

so ribs running in short direction

so ribs running in short direction

Yes, shortest distance for air to escape when bedding in.

Thanks all. Short way it is then

If you back butter them ...They will bond irrespectively...

But if you trowel adhesive on the floor length ways when laying long planks you run the risk of trapping air in the ribs of adhesive, potentially leading to reduced bed coverage and voids. Yes they will bond, but maybe not as much as if you trowelled the adhesive the other way.

Morning Plan Tec....
Excuse my naivety .. and I am always willing to take on advice... But .... Surely when a floor is serrated.. North to South.. East to West.....(Or the back of a Tile) ..Let's say with a 10mm square detail..The coverage will be 50%
When pushed/ Rubbed home .. The serrations collapse and theoretically should meet making a full bond..
I understand that when you say that serrations through the length of the tile may trap air ... But then surely that must be the case for every large format tile then, and I'm sure we don't lift every tile up to check otherwise..The next plank job I do , I will certainly put to the test though and come back with the evidence ... Be it damning or not..
Cheers

in my opinion,
now you are looking for the hairs in the egg.
we are talking about 120x20,
trapped air,
It remains a speech for large formats and that's it.
after all, I'm just an aprendist ....
and I NOT have no floor that is raised.
this is enough for me, I'm not interested in the direction of the adhesive.
(Again, I consider the answers above,
valid for large formats, example 100x50 and above)

I was referring to the question in hand here..... planks. The best way to trowel the adhesive in this situation is across the width, not length as I stated.

It stands to reason with large format, anything square or even rectangular that it is virtually irrelevant, but with a plank it is different. It is no extra effort to trowel the shorter distance and you are likely to have a better bed coverage. I only see the positives with this method I'm afraid.

I agree geoff,
but a simple question,
he does not need answers from a pharmacist.
already it is complicated to lay plank,
enter and exit a room, work
in tight rooms, etc.
if I must also look at the direction of the adhesive .....
in large spaces, I can also do it.

 

[GAZ5518]

Lol...."Likely".....
In the scheme of things I don't think it would be critical that you have to serrate against he grain to achieve a better more secure end product ... But I do enjoy debating it ... We digress..

Splitting hairs I know but it would take longer to trowel several times across the width than trowelling along the length .

I don’t think anyone is struggling for 10 seconds !

Always short way and always one direction, it’s no more diffficult or time consuming really, so why wouldn’t you.

Is it? I wouldn't know as I've never done it. To be honest I have always trowelled towards me on floors. Spreading right to left first to key it in to the surface first, then trowel towards me. Works for any substrate to fully fill voids in Ditra, key in properly to screeds etc

Ooooo.. Sunday morning has arrived and everyone is waking to a brand new day...
Pictures I found enclosed ...how would you deal with this scenario .... To drive you serrater officionados going..lol

By trowelling towards me as I always do. It's not a plank tile is it? Wood effect yes, but not a plank.
I imagine everybody else will lay these as they would lay say 60x60 or 60x30 tiles, trowelling in whichever direction they normally do!
Why, would you lay each piece into adhesive trowelled along it's length?

 

[GAZ5518]

They are examples of patterns that are achievable using "Plank tiles".. Which would make the serrations against the grain an interesting project!... Especially the herringbone...
And to answer your question .. I wouldn't be so anal..!!
As long as I was happy with the the Tile ... Irrespective of its shape .. was stuck and adhered in the correct manner

 

[Qwerty]

I think you have lost the point with this. If large plank tiles were laid in that fashion then I would still trowel across the width rather than the length, changing the direction of the trowelling when the pattern changed. With herringbone it would actually be trowelling at 45° angle across its width as opposed to 90°.

My head hurts now...

 

[GAZ5518]

Can believe it .... The Blimmin "Serration Police" are a my door.... "You'll never take me alive".....lol
But seriously ... I get what you saying.. But really ... I was just pointing out that it won't make that much of a difference should someone go with the grain.... No lives lost..
Have a good day fella

Depending on the length of the plank I usually use 3 or 5 dabs, I prefer odd numbers as I find that gives me better coverage.

 

[paulphur]

I have started and spreading across the tile in short direction, seems to be working just fine so thanks for all the adviceView media item 15488
