Permanent joints for paving around the house?

DanSand is known for joint sand, stone powder, etc., but these have only been dry infill products; I myself have not yet experienced their joint mortar.

That is not mortar. That is very fine brush sand with some cement in it, which then hardens when sprayed with water.

Sand + binder (cement) + water = mortar

yes, that was also meant that way, with the joints in rubble paving or in chamfered pavements, that some moss then grows there

and pressure washing on hardened joints works well? doesn't damage anything?

I checked with Dansand. They have regular joint sand "no grow," which is simply swept in, and the "Top Lock" "no grow," which is slurried with water, but with the latter, there is apparently a risk that the binding agent contained may leave a grayish haze on the paving surface. Has anyone tried that one or only the regular "no grow" joint sand?

I the Top Lock. No problem.

I guess if you do it as Nordlys described: sweep in and then pour over, then no cement residue will form. Or?

If you slurry it from the beginning (spread, wet, and sweep in the slurry mass), then you will also get cement residue on the surface, would be my guess.
