Where to buy reagents for technology "Washed concrete"?
Many articles on this channel devoted to describing the manufacturing process of decorative blocks, tiles, etc., having a surface made of natural gravel. Made by the so-called technology "Washed concrete."

One of them - is the use of retarder or hardening of concrete whose composition does not quickly gain the strength of the thin layer of concrete in the forms. He scraped or washed off.
