How best to Tile a room?

[mp3wizard]

firstly thanks for taking the time to write,

I was told that I should buy a 12mm trowel earlier,

well as i'm laying on big boards not floor boards, is that still relevant? I'm not sure what brick bond is, today is the first time I've realized i'll need the levelling boards, so i'll have to do some research.

Mechanical cutter is Jokosit Professional Tile Cutter 800mm/80cm Plus Extra Titanium Gold Tile Blade

Wet cutter is Vitrex 113402NDE 450W Torque Master Tile Saw 240V

The adhesive is - Keraquick white fast setting adhesive 20kg x 5

The Grout is - keracolor sf 100 white grout 5kg x 1

I realise that i'll have to do small areas because the adhesive sets quickly.

I have read somewhere that for small grout lines of 1mm the floor would need to be very stable and a high quality tile, seeming its a level floor which will have levelling boards and I believe the tiles are high quality could I reduce my grout line?

You can change the adhesive for slow set,give you time to set right.

Take the fast set adhesive back and get standard set, it'll have gone off in the bucket before you've got your first tile laid. White grout on a floor isn't usually the best idea either as it won't stay white for long! 3mm is the British standard for floor tiles.

First things first, honestly, I'd suggest you exchange your adhesive for a standard set.
You won't cope with a rapid with those tiles.
You'll be mixing one batch per tile probably,
and you'll have no time to makes adjustments if needed.
Measure your tiles from corner to corner diagonally, that'll give you an indication as to how good they are. They should measure exactly the same on both axis.
That's two measurements per tile, both diagonals.
Measure a few and make sure the result is constant.
Then lay them face to face and see if they are flat. If they're not, they will rock or spin about the centre.
That'll indicate how you'll need to apply adhesive.

This is brick bonding the insulation boards.
And taping the joints. It's a scrim type tape, covered with tile adhesive.

it's from Tile Mountain, i'll have to see if they will exchange.

if they do come back as consistent after measuring could I reduce my grout line?

Yes i'm living in dream land where I think no-one will actually walk on the tiles, they'll just gaze from afar at how nice it looks

great ok, thanks for the pic, so providing its taped at joint I can use the tile adhesive I already have.

[mp3wizard]

Yes British standard, but I've seen other forums that say if they are high quality tiles with optimum floor levelling it can be reduced to 2mm.

If not already mentioned, invest in some levelling clips, you'll be glad you did. Definitely go over your UFH wires with SLC, it will protect the wires from any mishaps with the trowel etc while you're tiling, follow the installation instructions to the letter with the UFH, particularly the bit that says check the mat after each stage with a multi meter. Don't forget to back butter the tiles. 🙂

The insulation boards have nothing to do with the adhesive you use, no.
You need to change your adhesive to a standard/slow set.
Your existing floor, is it completely stable?
Is there ANY bounce anywhere?
Get a totally brim full glass of water, place it in various locations around your floor and walk around it and see if it spills.
And don't tip toe so that it doesn't.
You should be able to try and make it spill and it not!
You can't do anything else until you have a sound base to start with.
If these basics are not followed, it will end in tears!
