I'm a bit of a cement novice, so I'm not really sure what to expect.
I'm trying to do a semi dry mix for the edge course. The sand has some moisture in it, it's not a crazy amount, but you could make a sand castle out of it.
I'm mixing it with cement in a 4 to one ratio. I'm then stomping down, topping up, and then tapping down the edge course pavers. It's up against a wall, so there's no haunching.
My concern is that after a couple of days it seems too crumbly. it has the feel of sugar that's been in a bag too long and has formed a crust: you can easily break it up with your fingers, and is very dry, and crumbles between your fingers.
It's in a shaded spot, but it is warm out there at the moment.
Should I just wait it out? will it harden over the next few days? can I help it along in any way? is it only ever going to be this crumbly? should I add a bit more water?
any comments gratefully recieved!
