using dry mortar between stones

| i just laid a small L-shaped landing underneath a fence gate using sandstone fieldstone. nothing fancy, just something to walk on through the gate so i don't have to mow there.
these stones are set on a gravel base, then in leveling sand. they are irregular and what i'm planning on doing is dry sweeping mortar into the spaces between the stones, wetting it down, sponge wiping the stone to remove the mortar, and then just letting it dry. i'm pretty sure that the small spaces will dry up hard, but am wondering if the mortar in the larger spaces 2-4" will harden up or will remain soft. has anybody done this and what were the results? |

| i wouldnt recommend using mortar between the stones, it will definetly crack with the movement of the stones. only use a cement base product when you are setting your hardscape material in cement. i would recommend sweeping in sand, soil or screenings[stone dust] for your application. |

| The logic is that the surface will set but the sub-base won't. The sub-base will shift breaking up the surface. |

| It all depends how big are your flagstones. I did a walkway with 2'x3' and 2.5" falgstones, filling the spaces (never wider than 1") with dry mortar. Nothing is moving or cracking, no way! |
