Some years ago, I had a new tarmac drive - with a line of pavers all round to finish it off. The people doing it pointed between the pavers using a mortar gun - and made it look very easy, but I suspect that there is a steep learning curve! I later bought a mortar gun but have not thus far had the courage to use it.
I have a patio which is in need of re-pointing - and would be an ideal candidate for the mortar gun.
I would be grateful for any pointers(!) as to:
- what sand to use and what sand to cement ratio
- what - and how much - plasticiser to use make the mortar flow
- anything else relevant
TIA.
