Laying quarry tiles outside

alexisuk_2

We replaced our horrid cheap pine floor (overlaid badly on concrete) with lovely 4 inch quarry tiles. The guy that did this was fantastic. So it runs the length of the hallway, out the front door to a step (front door replaced afterwards so seemless tiling).
We now want to continue outside from the step to a gate. Unfortunately the guy has since retired, so is unable to do the job.
The area is about 1-1.5m2, so not huge. We need to cut a few tiles, but we have a tile cutter.
My question is - what sort of sticky stuff (technical me!) do we need underneath? Does it need to be anything special as outside? Or special as quarry tiles?
Thanks

Mortar - cement mixed with sharp sand or builders sand.

I can't claim much credit, I used to be a landscape gardener and my esteemed colleague Mr Google found that link which was pretty good.

Your bog standard DIY shed tile cutter won't do for quarries. You'll have a broken cutter and lots of broken quarries or lots of quarries that are marked but refuse to be cut. You need a professional heavy duty dry cutter or a suitable wet cutter or a grinder.

To stick em down the above will work but I'd prefer to use a proper tile addy rated for external use. Prime the substrate with an acrylic primer first and DON'T spot fix - make sure you use a solid bed.

I'd second keystones post. assuming your laying onto an existing concrete bed use a real tile adhesive (cement based not pre mixed).

may be worth hiring a decent watercooled cutter if you only have a few cuts

Make sure your insurance is up to date, when it snows you will have a death trap

these quarry tiles are not the red glaze shiny ones, but red/black with a slightly rough surface for non-slip (does not make cleaning with mop very easy as shreds them)

thank you for this. our tile cutter is a watercooled cutter, not the cheapest but pretty good. do we still need something more hard-core?

you may well be ok if you take your time. i take it they are the 8mm think ones rather than the big old welsh 12mm ones?

You need a product like Ardex S21 which is a frost proof bedding mortar. (available from specialists tile distributors - not B&Q type places).

The important thing with a job like this is making sure you have no voids under the tiles - that's where water gets into, freezes, then bursts the tiles up.

Hire a decent tile cutter, anything remotely DIY will not cut quarry tiles.
