Specifications

Color Hardener is a premixed dry-shake product simultaneously colors, improves finishing, and hardens freshly placed flatwork

QC COLOR HARDENER is a formulated, dry-shake, colored surface hardener. It is used for coloring, hardening and conditioning freshly placed concrete flatwork. QC COLOR HARDENER is a surface-concentrated coloring method that hardens and densifies. Uses and Benefits

QC COLOR HARDENER increases abrasion resistance and surface density and reduces porosity..

Used in conjunction with QC RELEASE POWDER, QC COLOR HARDENER is the preferred product for creating vibrant colors for imprinted/textured concrete. (See separate Product Information Bulletin for complete instructions on QC RELEASE POWDER.)

QC COLOR HARDENER is an excellent choice for the following types of projects:

Colored, imprinted concrete flatwork and a variety of architectural concrete treatments that would benefit from improved pattern transfer and increased abrasion resistance.

Surfaces which require increased abrasion and impact resistance, such as street paving, warehouses, shipping/receiving areas and distribution centers. Interior and exterior surfaces exposed to heavy daily wear and high-impact use. When concrete has been properly air-entrained, surfaces in cold, harsh climates exposed to freeze-thaw cycles. With its blend of select and gradated aggregates, architectural cements, and plasticizers, QC COLOR HARDENER creates surfaces that are substantially harder and more wear-resistant than concrete not treated with color hardener.  QC COLOR HARDENER is available in 42 standard colors and a wide range of custom colors.

QC COLOR HARDENER is an excellent choice for coloring concrete in order to achieve lighter colors and/or more brilliant colors.  Light-reflective surfaces can be achieved through the use of a selection of white or light QC COLOR HARDENERS.  The synthetic iron oxide pigments used in QC COLOR HARDENER meet or exceed ASTM C 979 and produce brilliant, streak-free, non-fading surfaces.

To produce enhanced and richer effects, white-based QC COLOR HARDENERS* can be excellent base choices for the application of QC PATINA STAIN* and QC CEMTINT*.

Due to extensive quality control measures in product manufacturing, QC COLOR HARDENER is designed to produce uniformity of color without color drifts. In addition, use of color hardener does not risk day-to-day variances experienced in ready mixed integral coloring.

For high-traffic surfaces as well as commercial and industrial surfaces, QC HEAVY-DUTY COLOR HARDENER* may be used. A detailed Product Information Bulletin for QC HEAVY-DUTY COLOR HARDENER* is available.

 

Application

 1. Once concrete reaches the point when no bleed water remains on the surface, QC COLOR HARDENER should be evenly hand-broadcast or mechanically applied on the surface.

 2. QC COLOR HARDENER is usually provided in two shakes, with two-thirds of the product being applied in the first shake and one-third of the product being applied in the second shake (while also holding back a small amount for touch-up work).

 3. After the first shake has been uniformly applied and has absorbed water from the slab, the surface is floated. Wood floats are recommended during this first application.

 4. Apply the second shake perpendicular to the first application in a uniform manner.  Magnesium or fiberglass floats may be used after the second application, providing all bleed water has left the surface.

 5. Saw cuts should be made as soon as possible without disturbing the joint edges.

 6. Care should be taken to prevent hard-steel trowel burns, especially at tooled joints and edges.

 7. In dry, hot or windy conditions, the use of an evaporation retardant/finishing aid may be considered.

 8. For high-traffic surfaces as well as commercial and industrial surfaces, QC HEAVY-DUTY COLOR HARDENER* may be used. A detailed Product Information Bulletin for QC HEAVY-DUTY COLOR HARDENER* is available.

 

Application to Vertical Surfaces

 

1. QC COLOR HARDENER may be used to finish vertical surfaces such as curbs or the faces of step risers, but the product is not designed for use on large areas of vertical surfaces.

 2. A plaster mix of QC COLOR HARDENER may be used when doing steps or other vertical surfaces. To create this mix during the final set stage of the concrete, add only enough water to QC COLOR HARDENER to achieve a workable consistency. Then apply the plaster mix to the vertical surface while the concrete is fresh and finish as normal.

Curing and Sealer Color Hardened Concrete

 

1. For curing concrete treated with QC COLOR HARDENER, choose from a variety of QC cures appropriate to the project requirements: QC CLEAR CURE*, QC COLOR CURE* or QC COLORWAX*. QC CLEAR CURE* and QC COLOR CURE* conform to ASTM C 309. QC CURE AND SEAL SB* conforms to ASTM 1315.

2. For sealing concrete, choose from a variety of QC sealers appropriate to project requirements: QC CEMSEAL*, QC SOLVENT-BASED SEALERS*, QC PERMASEAL*, QC SURPRO* or QC ULTRASEAL*. If further protection is needed or a membrane-forming cure is not appropriate, a new, non-wrinkled, non-staining, reinforced, kraft-curing paper may be used.

 

Maintenance

 It is highly recommended to develop and follow a routine maintenance schedule for all colored concrete so that it maintains a top-quality appearance. Colored concrete installations should be routinely inspected, cleaned and resealed as required by the local conditions. Cleaning and resealing schedules will depend on a number of factors including, but not limited to, volume and intensity of traffic, maintenance procedures and weather.

 

Shelf Life

QC COLOR HARDENER has a shelf life of one year if stored in dry conditions.
