Liquiblack is an industry-leading carbon black pigment. While it is used widely in concrete, pool plasterers and other contractors also use it as a black pigment for a wide variety of projects.
LiquiBlack is popular among pool plasterers, who use it to darken swimming pool interior surfaces to achieve colors ranging from light grey to black, or to darken other colors when mixed with various hues to create intense shades. It can be used in plaster-only pool surfaces but is often used with pebble and many other types of aggregates. It is capable of achieving extremely dark, or evenly an entirely black color depending on the amount applied.
