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

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

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..
