Actual Tapecrete brand acrylic concrete is very expensive and hard to get here in the USA, however I did some research on it a few months back and found this alternative.

It is readily available at Home Depot and other DIY stores:

Quikrete Acrylic Fortifier

Use this stuff instead of water when mixing up your batch, then apply it with a paintbrush or sponge.

I mix it with this:

Quikrete Quick-setting Cement

You can also use it with tile grout and plaster of paris. I do not suggest using plaster for wet type set ups.

This stuff is a bit strange to work with at first. You want to mix the concrete with the acrylic using no water. It needs to be the consistency of pancake batter. Then brush it on your form that you carved out of white floral foam. It is better to use many thin layers rather than one or two thick ones. Mix up only what you can use in ten minutes. It dries fast but wait at least 24-48 hours between coats.

Here is a picture from one of my in process projects using this stuff:
