|Concrete feet test sample. Nikon D7000|
My concrete test samples are starting to look pretty rough now. They have been on the patio for a few years, being exposed to the elements to see how they fare.
This test was originally a cast of my toes, but in trying to make the concrete very white, I added an extreme amount of gypsum.
The cement was slightly porous and so the wet soaks in and the frost then blows apart the concrete.
I rather like the effect really; ever changing too.
I doubt you could get cream strong enough to cure it though :)
