Hello everyone!
We are having anthracite concrete pavers, 60x40x8 cm (24x16x3 inches), installed on our covered terrace.
I’m currently thinking about the best material to use for jointing. I’ve heard about using “hard” joint filler to prevent ants and other insects from nesting there.
What would you recommend?
I look forward to your advice!

I just went to the local hardware store and bought 80 kg (176 lbs) of solid jointing sand that is permeable to water. I hope basalt grey matches anthracite paving stones. Why so much? I think we had a 15 kg (33 lbs) bucket.
Best regards,
Sabine

I think it was called “Tubag PFK” pavement joint mortar. It was quite easy to work with.

SabineYeah, but that stuff smells really strong. Not for people with a sensitive stomach. The smell lasts for a few days.

Sabine Did you sweep it in dry first and then moisten it? Or did you mix it with water?
I'm worried we won't have enough and that the paver might be left waiting, so I'd rather take an extra bag... Our slabs are 8cm (3 inches) thick. That means quite a bit goes into the joints...

I’m worried we might not have enough and that the paver will end up just standing around, so I’m taking an extra bag... Our slabs are 8cm (3 inches) thick. That means quite a bit goes into the joints... We first pre-wetted the patio slabs using the garden hose, then immediately poured the mixture straight from the bucket and slurryed it onto the slabs with water. We swept it into the joints using a broom and a hand brush. We kept spraying a little water on top, then swept in any gaps that appeared again, and so on. At the end, we carefully washed off all the leftover mortar with a cloth and a bucket. It was easy but a bit tedious. I was glad we did it ourselves because I can’t imagine a landscaper crawling on their knees across the patio like I did, examining every single joint closely.
Best regards,
Sabine
