Review: Colorant - Bluetiful!
Review: Worked great - We spent $750 on real flagstone in our back yard project but needed another $650-$700 in additional flagstone to complete our walkway. We decided to make our own flagstone using vertical blinds as forms that we shaped, bagged concrete and this incredible dye to turn the concrete black by spreading about 2 -3 tablespoons of dye to the top of the freshly poured concrete. Total cost was about $100 in concrete, $20 for the vertical blinds and the coat of the dye. Get creative and save a ton of money by making your own flagstone pavers. The dye comes in various colors.
