I finished relaying the paver stone pad in front of one shed.
Ended up re-cutting , with a stone saw, some bricks as the pattern changed even though I did not change the pattern but while it looks like it was planned by a drunken Irish Man, it looks better than before.
I used Polymeric sand both as a base and as crack filler so it should not move or sand be washed out of the cracks and it is supposed to be good for stopping weeds. (Though on another side walk I found it does not stop ants from digging holes in it.
