large format tile gaps

[Gary Freeman]

I am laying some large format tiles 100cm x 50cm soon and i always thought the gaps should be 4mm plus ? however you see many tile jobs with small gaps eg, 2mm ?
I would really appreciate some feedback please

 

[Flintstone]

The area they are being fitted too plays a part in the spacing, where are they going ?

 

[Dumbo]

Also where are you getting the tiles from , this may reflect on quality of sizing and therefore have a knock on with tile spacing

 

[Waluigi]

The main thing to do is get the walls level.

Tell yourself that a perfectly plumb wall is the shortest possible distance from the bottom of the wall to the top.

If your adjacent wall isn’t Plumb then that same point from the bottom of the wall to the top of your wall will be longer so the spacing between tiles has to increase.

 

[Waluigi]

Ignore that if you’re laying on the floor.

Hi All,
perhaps i did not explain myself properly so apologies,
the floor is 75 Sq meters, 40 Sq meters of this is is a perfect rectangle for a new built extension, the rest is through a hall way and kitchen / Diner.
The tile sizes again are 100 cm x 50 cm and to clarify what tile gaps would you be looking at ?

If the tiles are rectified i would use 3mm if not then i would
use 4mm

 

[Qwerty]

3mm is usually my choice in that scenario

I think I read recently the B.S. has changed re joint sizes for large format tiles, not that 1 x .5 is counted as large, or maybe it is under the B.S.

 

[GoneGuy]

3mm dependent on quality of tiles

 

[Gary Freeman]

Hi All
thanks for coming back to me, it looks like what i thought 3 to 4 mm
best regards

New BS regulations don’t come in to effect until the piece exceeds 1200 x 600mm.

...and a 5mm joint full of micromax2 will SOOOOO good on very large formats!

Bal worrying they won't sell much grout . So persuade working group to increase joint size

Vested interests and over-speccing.

 

[Dumbo]

Think how grout sales have diminished over the years 6" quarries with wide joints to 300 x300 with 5 mm joints to 600x600 with 3mm joints some tighter .

 

[Waluigi]

Look at what Bal are charging for a 10kg bag of Microflex. £30 odd. They can whistle.

My last floor size was a similar rectangle , laid 120x60 rectified porcelain onto Kerakoll idro build Mat , followed expansion gaps on liquid screed floor , with ufh and put a soft joint in the middle of floor with matching silicone used 2mm spacers ! Can’t see anyone wanting a 4 mm joint with an expensive tile, but that’s just my opinion!

I've just done 50m2 the same size and used 3mm. Tiles were perfect and could have done smaller but it's always nice to have some breathing space!

All my quarry tile were always done in sand & cement...... cheap as chips

Personally I hate anything over 2mm. I'll go to 3mm on a large floor tile if I must.

Hope not to offend by sabotaging thread but I'm just about to tile a wall with 120x60 porc. and was going to use 2mm or 1.5mm gap. Is there any reason I shouldn't? the wall is only 1.8m long two tiles high. (shower cubicle)

If your wall is stable and load bearing and has no deflection, 2mm will be ok.

...and if the tiles are rectified or straight enough and evenly sized to allow a 2mm gap.
