I adore concrete and it’s versatility.

The smear: Aim for lots of little streaks and chunks. Because white portland cement and white sand are significantly more expensive than the stuff you buy at home depot in 80-lb bags for a few bucks, I had a decorative layer with white and grays, then poured gray over it in a few layers. Once the first layer of gray was poured over the white streaky bits, I stuck my fingers in to blend the colors a bit here and there. You don’t want to blend too much – stone tends to have well-defined streaks created by layers of sediment built up over years.
Here’s where I encountered a sticky problem — make sure you have your mold raised up, so you can access all sides with a vibrating device (I like to use a power drill with a mixer bit, or hammers). Because I had it on the floor, I had limited access to the sides of the form, which meant more air bubble patching when it came out.
