Hi Folks
What a great website it inspired me to do a bit of paving, 18 sq/m of Indian sandstone. Flags are layed on concrete with 20-30mm sharpsand/cement bedding. Job was going well until I did the pointing. I used sharpsand/cement 4 to 1 semi-drymix with a touch of plasticiser. Joints vary between 8-14mm. I packed the pointing into the joints.
I did this yesterday which was quite hot day so after pointing I used a water spray bottle to dampen the mix. 24 hours later I find that the pointing hasnt set hard still loose. Can anyone shed any light waht has gone wrong please?
Thanks

It's too hot and your mix is to dry.

Thanks, confirmed my suspicions. MSH I had read that section but decided to go with a dry mix, what do I know`! So it looks as if it needs re-doing with a wet mix or could I get away with a dry mix if I give the flags a good hosing down the night before so as there is plenty of moisture to set of hydration?
Not look forward to re-doing my sodding back is killing me
