Primer, adhesive and grout for coping stones

[Steve111111]

I bought some coping stones to lay over a low 'wall' in the garden. Looking for advice on how to fit them.

In the store I bought them in they sold me a big bag of adhesive (only comes in one size) and some grout. They convinced me the adhesive was a lot easier to use than mixing up mortar. I had assumed it would have been like a tub of PVA that I would just 'paint' on to the wall and stones, not a like a bag of cement.

I asked them about fitting them and all I was told was to prime the stones first. So I just need to figure out how to install them. Unfortunately the bags are in German.

I do have some primer (Evo-Stik Primer 918) that I used to prime a concrete floor before. Would this be suitable for priming the stones?

I presume I should apply the adhesive just like mortar? I'm wondering when to apply the grout for between the stones. Should I lay the stones first and let the adhesive dry and then apply the grout? Should I get some spacers to put between the stones. Or just roughly leave a few mm between them? I don't have any spacers and would rather not buy a bag of them if I don't need them.

Those products have English data sheet if you need instructions.
You should use the correct matching products and not use the primer you have.
It might not work as not tested like the correct matching products.
I think you need Botament BotaGreen Primer? Look online at data sheet for confirmation

Just apply like laying tiles.

5-10mm gap between the copings.

Apply the grout as you wold with tiles though you may have to shutter the overhang to stop the grout just falling through.

My Tilers van is full of bags of spacers:- I still used clothes pegs when I done my coping stones !

I was hoping to have a tight finish like in the attached photo where's there only about 1-2mm between the copings. The copings are a lot thicker than tiles so wondering the best way to completely fill the space between them, or is this even necessary. I suppose I could use a scraper to feed the grout down through the space.

t 1-2mm between the copings.

I wonder if I really need to prime the copings. If I back buttered them with some adhesive and had a layer of adhesive on the wall would that be sufficient?

No short cuts when using building materials.
If you do it to spec then you should have no problems.
If you want to try an alternative method then take the risk
Up to you

I've always used mortar with a good drop of SBR in for coping stones, and they don't come loose.
