We have a sandstone patio that was laid about 2 years ago by a contractor. Almost immediately the 'concrete' between the paving slabs started to crumble in some places. We had the contractor back last year, but again we have the same problem. we want to re-point the whole patio now ourselves.
Please can you advise on the best concrete/sand mix for sandstone laid 2 years ago and the best method to use. Thanks very much
