I've listed this in two topics as I wasn't sure where it should go.
I have a concrete base that was once used for a shed. It's in good order, no cracks. I want to lay a blue black natural slate paving circle design on top of it. They are machine cut but still vary a little in thickness.
What is the best method of laying these? I keep reading conflicting results! Whether it should be dabbing each corner with mortar mix or onto sharp sand and cement mix. I'd prefer it not to be cement mortar direct onto the cement base as you never know that at some stage I may want to change it and then they'd be hard to remove. So what would be the right method please.
How do I deal with drainage or is that not a problem? the area is approx 2.4m squared. And is just a patio in the garden not joining the house.
What about the pointing or can grey grout be used?
Any advice much appreciated as I've never done anything like this before but would like to have a go! Many thanks

If you are going to lay it then it will need to be done properly.
1. Dabs are not sufficient for any paving let alone slate. Slate is not as porous as other stones so it needs to go down on a full bed with a bond bridge.
2. If you dont use cement as you have mentioned then the slabs will be rocking and moving within no time. If you did opt to not use cement then there is no value in pointing the circle either because the movement of the slabs will render the pointing useless.
3. The circle will need to be laid on a fall (check out the main site for specifications think 1:40 is the right falll but double check the main site)
Unless you do it properly its going to cause you nothing but trouble.
Spend an hour reading the main site and you will find all the techniques detailed.
