I have constructed a multi-level patio with concrete steps joining them. On the patios I have used a cement and sharp sand semi dry mix as a bedding layer. But what should I use to bed the flags onto each of the concrete steps. Should I use a cement sharp sand mix again, or should I be using a cement building sand mix for extra adhesion (as I obviously don't want the flags to work loose off the concrete steps as this would be a safety hazard). Any help or advice would be much appreciated.
i would add PVA or ronafix if you can get it to the mix, and yes would make it a lot wetter
and would ask the client not to stand on the edges for a day or 2 (which they normally seem to love doing)
