PC Products PC-Crete Moldable Epoxy Putty, 4 oz Stick, Concrete Gray by PC Products

I bought this because a bird bath I inherited had two cracks in it and was losing water.I expected it to be a bit softer. It took a bit of work to get it blended and by then it was starting to dry. It pushed into the crack easily and dried quickly. When it's dry it looks just like the surrounding concrete. When the bird bath gets wet though, it looks like white plaster, almost. It is obvious it's a patch. I wouldn't use it on anything really obvious and expect it to blend but the birds don't seem to mind.

I used it to repair a stone lion by the entrance. Some work was previously done on it by contractor who did not distinguish himself. The composite worked nicely and we not only fixed the cracks, but restored a "missing" tongue. Not for large repairs since the amount is small and I had to nut it three times to get the job completed.

Perfect product for small concrete repair of any kind. Easy to use, set fast. Once mixed (uniform color), don't delay in application (takes just 3-5 min to firm up, 24 hours to ROCK hard, stainable/paintable concrete). Portion-able product packaging left material for another use.

Took a little longer to get so I had to use something different to make my repairs. I plan to keep it, seems like it is a good item to have around.

I got this for patching bolt holes on rock climbs. I've used Instacrete in the past and the two products seem pretty much equivalent. Knead it well, pound it into place, rub a little dirt on it, and the hole is erased. I'm docking a star because the packaging isn't that great and they initially sent me a tube full of air, presumably because the lid popped off at the warehouse and the putty fell out and some stoner dude shipped it anyway. This was a minor inconvenience -- they sent a replacement and I returned the tube full of air. Maybe they can give it to the stoner dude and he can make a bong out of it.
