I didn't use any additional aggregate, just the Quickrete Quick Setting cement. I started by mixing it at a 5:1 cement:water ratio as recommended for a more watery mix (they say 5.5:1 for a less watery mix). It seemed to be too dry though, especially to get it into the nooks and crannies of the teeth, so I added a bit more water to the mix. It seemed to be ok then, if still slightly on the dry side, but looking at your pic of the mix in the mold under Step #1, mine definitely wasn't as watery as yours. I tapped on the mold and then put it on a piece of plywood that I vibrated by holding an orbital sander underneath. I did everything, including letting it set for about 5 hours, indoors figuring it's too cold out in the garage lately with nightime temps getting close to freezing some nights.



And yes, I'm in the US, specifically Maine. I got the Quikrete two days ago at a Home Depot store. The only way it could be old is if it's been sitting at the store for a long time. They had the Cement All also, but the Quikrete was in a smaller container, so I got that because I don't know when the next time I'll use it is. Looking at the labels, the mix ratios, drying times, and other info seemed to be very similar, so I thought the Quikrete would be a very similar product to the Cement All.



I'll try it again with a more watery mix, aiming for a consistency like in your pic. And, I'll give it a longer drying time in the mold before taking it out.
