This photo shows US SPEC H2 that was not properly mixed resulting in a finished color that is not homogeneous.  Please always follow the mixing instructions on the packaging or data sheets when using US SPEC products.  For this product we recommend using a mechanical mixer with rotating blades or a heavy duty 1/2" or larger low-speed corded drill and mixing paddle.  We recommend also mixing for a total of 3 to 5 minutes.  This would have provided a consistent color match to the existing concrete.
