Default casting concrete

Quite a while ago some one had a post about using a castable and moldable concrete, I believe produced by Kwikcrete. They showed casting it in a mold and then post forming it by hand. I have lost this information and would be grateful if some one could tell me where to find it. Thanx

I use Rapid set Cement All, there is an additive for smoother castings and a slower set... but not hand formable.

I found what I was looking for. It is called ShapeCrete made by SackCrete available for order at HomeDepot. Instructions for use are at


home page is www.shapecrete.com


I plan to try some to make replacement tile roofs for my Alvarado hotel. The vacuum formed plastic sheets have not held up well.

I posted a while back about Shapecrete and was promptly informed someone had posted about it much earlier, even though the article I found on it spoke of it as a relatively new product. Ordered mine from Home Depot. Never have fooled with it. I bought it because they spoke of using it to do sculpture. I understand many use quick set concrete or repair concrete to do molds. I have molded with that and also years ago bought some special concrete for molding from some guys that cast yard statuary. Was called Fast Cast. Worked nicely.
