ᐅ Permanent joints for paving around the house?

Created on: 6 Jun 2019 15:40

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

By the way, DanSand is known for joint sand, stone dust, etc., but these were only dry jointing products. I have not personally used their joint mortar.

That is not mortar. It is very fine broom sand with a bit of cement mixed in, which hardens when sprayed with water.

Sand + binder (cement) + water = mortar

Yes, that was exactly what I meant regarding the joints in rubble paving or chamfered pavers, where some moss tends to grow.

And does pressure washing work well on hardened joints? Does it cause any damage?

I checked Dansand’s products. They offer a standard jointing sand called "no grow," which is simply brushed in, and the "Top Lock no grow," which is applied with water. However, the latter may carry the risk of the binder leaving a gray haze on the paving surface. Has anyone tried this one, or only the regular "no grow" jointing sand?

Best regards,
Sabine

I use the Top Lock. No problem.

I suppose if you follow Nordlys’s method: sweeping in and then pouring over, you won’t get any cement haze. Right?

If you apply a slurry from the start (spreading, wetting, and sweeping in the slurry mix), my guess is you would get cement haze on the surface as well.
