​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
