QC Color Hardener - Page 8

PRODUCT DESCRIPTION
QC COLOR HARDENER is a premixed, dry-shake, colored concrete hardener. It is used for coloring and hardening freshly placed concrete flatwork to produce an aesthetically pleasing pavement with a surface that is substantially harder and more wear-resistant than regular concrete. This coloring method can be utilized for concrete flatwork applications (salt finishes, broom finishes, rotary finishes, ect.), as well as verticle surfaces and other types of architectural concrete. Extensive quality control measures insure uniformity of color and virtually eliminate color drifts. QC COLOR HARDENER, a blend of specially selected and gradated hard aggregates, architectural cements, plasticizers and synthetic oxide pigments, produces a brilliant, streak-free, non-fading, wear-resistant surface. All the pigments used in QC COLOR HARDENER meet or exceed ASTM C 979.

QC HEAVY DUTY COLOR HARDENER is manufactured with additional ingredients, including natural aluminum oxide, and is used on high traffic and/or heavy utility, industrial and commercial concrete flatwork. These additional ingredients improve surface density and slip resistance.

DIRECTIONS FOR USE
QC COLOR HARDENER is hand broadcast evenly to the surface of freshly placed concrete when the concrete reaches the point where no  bleed water remains on the surface. In order to develop proper bond and adequate density, the moisture for wetting the hardener must come from the concrete substrate. QC COLOR HARDENER is usually applied in two shakes, with two-thirds being applied in the first shake and one-third in the second shake (holding back a small amount for touch up work). After the first shake, the surface is floated. Do not trowel between applications. Apply the second shake perpendicular to the first application in a uniform manner. Float in and trowel to the final finish desired. Install construction or control joints as soon as possible. Care should be taken during hard steel troweling to prevent trowel burns, especially at tooled joints and edges.
QC COLOR HARDENER may also be used as a "plaster mix" when doing steps or other vertical surfaces. During the final set stage of the concrete, add only enough water to the QC Color Hardener to achieve a workable consistency, then apply the plaster mix to the vertical surface and finish as normal.
Cure per specifications. (See suggested QC Cures below.)
