Precision Hardener

COMPOSITION:

APC Precision Colored Hardener is formulated with specially graded silica quartz aggregates, top quality Portland Cement Type I, light fast synthetic and natural iron oxides, for fading and U/V light resistance and proprietary additives. APC Precision Colored Hardeners meets or exceeds ASTM C-979 for color stability and ASTM C-4060 for abrasion resistance.

PHYSICAL PROPERTIES:

Aggregate Size 35-60 US Mesh
Aggregate Type Quartz, Silica Sand
Cement Portland Type I
Pigment Synthetic and Natural Iron Oxides

CONCRETE MIX DESIGNS:

The same plant should batch all concrete to avoid variations All concrete should be placed at the same slump. A 3" to 4" slump is recommended, with 5" maximum. Normal air entrainment, water reducing agents and delay set admixtures may be used. CAUTION: DO NOT USE CALCIUM CHLORIDE OR CALCIUM CHLORIDE BASED PRODUCTS IN COLORED CONCRETE. In cold weather, a non-chloride accelerator should be used.

USING POWDER RELEASE:

  • After the Precision Colored Hardener has been fully applied, and immediately before placing the mats on the concrete, the release agent should be broadcast onto the still plastic, colored concrete, and it is applied at a rate of 30 lbs. or 14 Kg per 1000 square feet or 93 square meters.
  • APC Precision Colored Release Powder forms a release barrier between the texture mat and the concrete. When the texture mat is impressed into the still plastic concrete, the moisture in the concrete disperses the pigment particles, which have been mechanically processed to encapsulate the release agent particle, thus leaving grout lines and stone indentations with the color of the Precision Colored Release Powder.
  • After the concrete has achieved it's initial set, in hot climates as soon as the next day and in cold climates as long as ten days, the release agent may be removed by pressure rinsing with a high power pressure cleaner, or a soap and water solution, and scrubbed with a broom. Care should be taken not to remove all the release agent from the concrete, especially from grout lines and deeper indentations.
  • To protect and help cure the concrete two coats of APC Precision Clear-Seal or Clear-Seal 30 is recommended

MAINTENANCE:

It is highly recommended to develop and follow a routine maintenance schedule for all colored concrete so that it will maintain a top quality appearance. Every 24 to 60 months, colored concrete installations should be inspected, cleaned and resealed as required by volume and intensity of traffic. The frequency will depend on a number of factors including traffic conditions, weather and geographical location.

CAUTIONS:

Use a facemask or respirator. Do not allow getting into eyes. Keep out of reach of children. Prolonged breathing will cause throat and lung irritation. Protect all adjacent areas. See Material Safety Data Sheets for further information.
