Hello,
During our last two visits to different building material suppliers, I noticed samples of “polymeric joint sand” (one was called Stones Eco Fugensand) at the counter. This joint sand is supposed to be suitable for regular concrete pavers and hardens when watered. It is said to reduce weed growth in the joints. Does anyone have experience with this type of joint material, or is it better to avoid it?
Best regards,
Sabine

I guess if you do it as Nordlys described: sweep in and then pour over, you won’t get any cement haze. Right?Certainly for (clay) pavers.
No-grow is not intended for that. As far as I know, there is no version with trass cement. It is only for concrete paving stones.
I regularly clean the surfaces with a pressure washer; the joint mortar is resistant to pressure washing and sweepers. Even a stubborn stain (no idea what it was) came off well when targeted with a strong jet.
Regarding cement residue, I can recommend products from Tubag (Quick Mix). I know them from demonstration applications—they leave no cement haze and are very easy to clean.

What you describe sounds like the latter, which would be less helpful in this case since the question about pressure washing specifically refers to Dansand no Grow. This has different properties compared to conventional mortar.
