Adhesive spread direction - TilersForums.com

[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?

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

You say tomayta ... I say tomatoe...lol
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.

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..
