Stone adhesive with expansion? Do you want that?

[Mikolino]

I'm going to make a custom build where I need to glue together a bunch of classic "tumbled byasten."

Biltema has a stone glue, one line should be enough on each stone, but it says that it...

"

• Expands 5–10% during curing.
• No expansion or shrinkage after curing.

I don't know how to interpret this (never glued stone before) I want the stones to be tightly glued block to block type!

Educate me please 👍

Some glue will seep into the gaps, but the stones are not pushed apart.
