Hi,
I have recently pointed a section of my sandstone patio with dry mortar mix (the one that's a little bit damp and can be squeezed into a clump) and it mostly looks ok. I have some patches where it is a bit flaky and sandy but I think it wasn't mixed properly.
After about 2-3 days I have noticed white areas around my flags, like salt marks in some areas, but others are unaffected. Is that just a natural process with cement setting and will it pass? or have I done something wrong? It does wash off the surface but re-appears a few hours later. How can I avoid it on the rest of the patio?
Many thanks
Kristina
