Its hard to get a good photo of sparkly concrete, but I’m sure you’ve all seen it on a sidewalk somewhere. Some people call it “urban sparkle”
A few years ago I tried to find out how to make it for my own house. I tried mica flakes, but it didn’t shimmer like I was hoping. Recently I searched the internet again and found several sources for sparkly sprinkles to add on top of still -wet concrete:
Sparklegrain
“Sparkle Grain is an eye-catching, black or white sparkle, concrete finish for interior or exterior concrete surfaces. Specifically designed for light to heavy usage on sidewalks, steps, ramps; in shopping centers, houses, garages, and stores; and in wineries, schools and public buildings.
Sparkle Grain also adds slip-resistance to concrete, which also means increased wear resistance compared to untreated concrete floors.”
“Concrete Shake-on to produce a decorative, glitter surface that is hardened, non-dusting, and non-slip.”
(Also for “General purpose polishing, lapping, blasting, compounds, vitrified and resinoid wheels, primarily for grinding and finishing non-ferrous and non-metallic materials.”)
Next time I’ll be ready!!!

mi pregunta es obre este spakle grain se puede utilizar sobre losa de concreto en un segundo nivel de un edificio,
segun entendi este producto se aplica sobre concreto humedo y si ya hay una losa de concreto vieja en un segundo nivel que me recomiendan hacer
por favor ayudarme con mayor informacion y la mejor forma de aplicacion ya que me interesa este producto para mis proyecto de construccion a los que me dedico
Very Sorry Luis, but this product is no longer available and I do not know where to get anything similar. Please let me know if you find it!
For Luis: Sparkle Grain is still up. The US Concrete Materials may have been selling 60 grit silicone carbide powder, which is commonly used for polishing rough rocks. Search for that you should find something shimmery enough to add to concrete surface when wet.
On finished concrete, the best and most economical option is to add pearl mica flakes in an epoxy layer.
