My chronicle and thoughts while I create a green corner of Galicia of my own.
I'm assuming you are referring to pointing between the stones? All good subministros should have bags of ready mixed sand and cement of different colours,it comes in a large number of colours I think they might have been 20kg bags. We chose a slightly lighter colour than the stone work. You mix it with water, you can buy pointing trowels, but I preferred to use a butter knife. To start with you will be slow, but you gain speed. I don't know if you remember our sitting room but that took me 3 months doing a couple of hours a day. I enjoyed doing it.
Thanks Anne! Good to have confirmation that its a DIY project. I´m wondering if anyone has thoughts on lime mortar v.s. cement.
