Thanks. One of my main concerns is that the mortar is so fragile. I could just keep scraping and it comes out like sand.
So I could repoint like an inch all the way, but if the middle is like sand, what does this mean?
Do o just keep scraping it out and filling ever deeper voids or what?
A mate of mine is a pointer. I often work on the same site with him. He normally rakes out about an inch, dusts off and puts in a bedding joint and later points over that.
