Hi all,
I have just put down an 80sqm cobbled path and am looking into options to point/grout it. Wet grouting will take 2 workers 4 days they recon, and at
120£ per day, will be expensive. Have looked into geofix polymeric sand grouting, but I will need a box of the stuff for every sqm and @ £25 a box, will be also expensive. I am thinking about going with dry grouting, 1 cement to 3 sand mixed with mortar colorant to make it dark grey.Looking at washing the cobbles down the day before grouting to get the cobble base moist, then the next day (if its dry) brushing in the dry mix, pushing it down firmly with my fingers. Should I be ok just to leave it at that with no more watering, i.e. will it go hard without spraying it with water? How long will the hardening take?
Cheers
Steve
