Quick question on the best mix for a waterproof, bonded, anti-dusting mix. I am guessing a 1:6 mix for the concrete is sufficient for 10cm depth, my question is on what additives I need to put in there?
If internal, I would add plasticizer and waterproofing agent. 1:6 might be a little weak, 1:4 would be my choice. And to reduce dusting it can be sealed.
