Advise On Trowel Type And Which Spacers For Quartz 600x600 Floor Tile

[Paul Panteli]

Hi,

Going to be installing over the next few weeks Gulf Quartz floor tiles 600x600 on a concentre floor in the kitchen.

Floor will be primed first and tiles back buttered.

I have read on this forum different opinions on which type of trowel and size to use - can you please advise best possible option please.

Also, i know min standard is 3mm for the spacers, should i be going for 3mm or 4mm? or is it simply a matter of preference

Appreciate your advise.

I would say 3mm is fine and that's what I would use, trowel wise, if the floor is nice and flat, a 12x12mm notch trowel should be spot on.

 

[Paul Panteli]

Thanks for the advice, does it matter if its a square or U shape trowel?

 

[Flintstone]

12mm square.

 

[Paul Panteli]

Great thank you.

 

[Flintstone]

You could go bigger if floor isn't perfect, I have just been doing one myself with same tile size and had to use 12x12 on floor and an 8x8 on the back of the tile too.

Did you put ditra mat down or not

How flat is your sub floor?
I've yet to see a concrete floor that doesn't need some slc on it.

Same here ,

 

[Paul Panteli]

Sorry I should have said that SLC will be laid just to level the floor. Do I still need a 12x12 trowel then?

 

[Flintstone]

Did you put ditra mat down or not

Me? No

 

[Stef]

I use a minimum 10mm square notch on a good substrate.
A 12mm trowel will do as you will end up with 2-3mm adhesive underneath.

Something that I am surprised no one has mentioned. You should be using a latex adhesive for quartz.

 

[Paul Panteli]

Yes will be using the two part adhesive Keraquick with Latex.

Tilemaster ultimate is rated for quartz I'd go with that coz all 2 part adhesive are miserable to use
