Hello - I have read the topics on pointing and mortars in this forum and also the mortars section on this incredible site.
I had an Indian stone patio laid 5 years ago; I now need to repair a small amount of the pointing - only about 5 metres total.
Last autumn I repaired about 2 meters with a 4:1 mix. After the admittedly hard winter this is all cracked and looks worse than the stuff I replaced !:(
The flags are 20mm thick and the joints 20mm wide. Would the 2 sand + 2 grit sand + 1 cement be a better mix for this joint ? Any pointers to make a more durable joint would be appreciated. As it is only 5 meter repair job the Romex product suggestion in another post would be a tad expensive.
TIA
Harry
