    ​MasterFinish HC

    Surface retarder for exposed-aggregate concrete

    How does MasterFinish HC work?

    MasterFinish HC is a chemical retarder specifically designed to produce uniform exposed-aggregate finishes on architectural precast concrete. Its excellent heat resistance makes it ideal for producing medium to deep etch exposed-aggregate concrete on panels that may reach 160º F (71º C) while curing.

    Recommended uses:

    • Architectural precast/prestressed concrete
    • Cast stone
    • Steam curing, heated beds, hot concrete temperatures up to 160º F (71º C) (Lilac, Pink, Tan and Brown only)

    What are the unique features of MasterFinish HC?

    • High heat resistance
    • Controlled penetration delays the set of the surface only
    • Wide range of etches available, including light etches
    • Depths of etch are color-coded
    • Can accommodate high-pressure water washing

    What are the benefits of MasterFinish HC?

    • Allows for year-round casting
    • Consistent water-washed, exposed aggregate surfaces
    • Variety of exposed aggregate appearances
    • Easy identification
    • Ease and speed of production
    • Saves time and labor when used as an alternative to sand blasting
