The mortar between my patio slabs has cracked due to age. I would like to replace it with some light coloured mortar/cement. The mix I have tried uses builder's sand with the cement - but the colour is too orange for my liking (due to the orange sand). I wonder if I could use playpit sand which looks much lighter in colour to mix with the cement or would this somehow compromise the durability of the resultant mortar?
I would be grateful for any advice please - thanks.
