What size of spacers do you guys use for floor tiles? Tiles being 300mm square.

I've used 2mm spacers on my wall tiles which are 400x230.

A lot depends on tile type, on polished porcelain I like a small joint, travertine a bigger one, ceramics ..... any more details ?

Ceramic and these tiles

Bought from a local tile shop though.

i would go for a 4 mm on those

3 or 4mm

whitebeam how do i get a picture on here to show

Go to FAQ at the top of the page and put in photos, that will give instructions.

I struggled with photos for quite a while

nice tile,,id do a 3mm

I normally go no smaller than 3mm with floor tiles

did this today 4mm spacer this my first pic so hope it works

Should go no lower than 3mm for a floor

so with those it would be 3 or 4mm

I'am using 2mm joint with calibrated 610mmx405mm Jura Stone.
The tile has a 1mm chamfer on the edge and any wider would give a massive unsightly joint - IMHO.

For 300x300mm tiles like yours I'd go for 3mm, but tile sizing can be an issue so check first.
Joint size and grout colour with floor tiling can often determine the aesthetic picture of the completed job - so great care is required in making that choice.

Thanks guys, some helpful replies there.

Grout will be Mapai Cement Grey 113

Also, 10mm notched trowel?

If the edges are recitified Id use 3mm with that grey grout as its quite light and you should end up with the same look as the kitchen pic above. If they are bevelled id go smaller as timeless john said or it can look huge otherwise

solid bed trowel Gary, (half round)

Thanks all - I opted for 3mm spacers.

Don't you just hate it when you run out of adhesive with 4 tiles left to go?

Inded especially if you were doing it on a Sunday!

I try to give weekends a miss now, did them for 30yrs+ leave them for you young guys now but yes to 3mm 4mm joints.
