Colour Hardener & Release Agent
Colour Hardener
Specially made Concreation Colour Hardener is designed to be worked in the surface of newly placed concrete. Colour hardener provides a streak free, consistent colour throughout the installation.
Hardscapes or exterior, colour ardeneris a durable colouring method. Time tested for over twelve years, Concreation Colour Hardener is resistant to freeze-thaw cycles.
A mix of Concreation Colour Hardener and water may be used as a plaster for vertical applications such as curbing and risers, to match hardscapes or interior floors.
Concreation Colour Hardener is commonly used in the impressed concrete industry to achieve the look of natural stone. It provides a dense, easy to work surface allowing various stamping tools to create a distinguished and detailed finish. All of the impressed finishes are completed using Concreation Powder Release (CCI-300) and a final finish using Concreation SB Acrylic Sealer (CCI-1000)
Limitations
- Coverage rates provided in 6.
- If not applied properly, the desired outcome will not be achieved and possible areas of the concrete substrate may appear. In addition, abrasion resistance on finished surface could be compromised.
- Concreation Colour Hardener is not recommended for a large amount of vertical concrete application. However small vertical areas can be covered by mixing Concreation Colur Hardener with water.
- Fluosilicate type chemical hardeners should not be used.
- Non-reactive aggregates (fine and coarse) must be used in the concrete substrate.
Composition and Material
Concreation Colour Hardener is a cementitious based product containing hard aggregates to achieve maximum strength. Concreation Colour Hardener is a streak free formulation, designed for use on freshly placed concrete substrates.
Finishes
Concreation Canada Inc. recommends finishes such as broom, spin float and imprinted when using Conreation Colour Hardener. Light sandblasted finishes are recommended for additional abrasion resistance.
Packaging
Concration Colour Hardener is available in 55 lb. bags.
Coverage
Coverage may vary according to the intended use and the type of colour. Concreation Colour Hardener should never be applied at a coverage rate less that 55 pounds (1bag) per 100 square feet. Heavier amounts of Concreation Colour Hardener should be applied for commercial applications or when light sandblasting is required.
Curing
Until completely cured, the colour of concrete is normally less uniform and appears darker than the final colur. Use of Concreation Acrylic Sealer (CCI-1000) will properly cure colour-hardened concrete, enhance the depth of colour, improve colour uniformity and provide surface protection. Once thin coat of Concreation Acrylic Sealer should be applied by sprayer at an approximate coverage rate of 1200 sq. feet with a live gallon pail.
Shelf Life
Concreation Canada Inc. advises that product should be used within 6 months from the purchase date. Also, Last in-First Out method should be used with inventories.

Powder Release Agent
CONCREATION POWDER RELEASE adds color variations and highlights to the textured surface, providing an attractive two-color antiqued look that very closely resembles natural materials such as cobblestone, brick, tile and slate.
The release powder is the highlighter not the primary colorant in the concrete; coloring of the concrete achieved by using color hardeners. Color hardener provides a greater color selection including light hues and pastel, the resulting finish has a harder more wear resistant surface and the material cost is low.
Features and Benefits:
- Allows a clean bond break between fresh concrete and stamping mats.
- Adds color variation-antiquing affect for stamped surfaces.
- Easy removal process allows for controlled removal to achieve desired shading effect.
Limitations:
- The final color of the concrete is affected by many factors. It may be a function of the basic concrete mix ingredients (fine aggregate, coarse aggregate, water and cement), the weather, finishing techniques, experience of the applicators, and coloring method used (color hardener or acid stain).
Factors Affecting Final Colour:
- Rapid moisture loss from within the concrete due to absorption from dry sub-grade or formwork.
- Rapid moisture loss at the concrete surface caused by wind, elevated temperatures or sunlight.
- Over working the concrete surface. Surface water should never be worked into the concrete. Always wait until bleed water has dried or evaporated before finishing concrete.
- Poor workmanship: Workers should be experienced in finishing, texturing, coloring stamp placement and removal, and curing and sealing decorative concrete.
- Troweling release powder into concrete.
- Weather; follow ACI guidelines when pouring on cold or hot weather.
Concrete Mix Design:
The concrete shall have a minimum compressive strength of 3,000 psi in non-freeze areas, 3,500 psi in moderate freeze-thaw areas and 4,000 psi in severe freeze-thaw areas. Portland cement shall conform to ASTM C 150 Type I, II, or V, depending on soil conditions. Aggregates shall conform to ASTM C33. Mixing water shall be fresh, clean and potable. In freeze-thaw areas only, an air-entraining admixture complying to ASTM C 260 shall be used to achieve an entrained air content for the particular mix used in accordance with the published recommendations of the Portland Cement Association. No admixtures containing calcium chloride shall be permitted.
Water reducers, plasticizers, accelerant, retarders and other admixtures are allowed as long as they have been thoroughly tested and approved to be compatible with color hardener, release powder and liquid release. Some admixtures while providing an enhanced performance for the mix may cause negative effects on the finishing and color of the slab; discoloration, stickiness (causing the stamps to “pull” concrete up) and other adverse effects have been observed.
Direction for Use:
After concrete is colored with Concreation Color Hardener and it reaches the proper set for imprinting, hand broadcast the release powder evenly over the surface to be stamped. Care should be taken not to trowel the release powder into the wet concrete; this will cause a permanent discoloration. After release powder has been applied, follow your regular procedure for stamping concrete.
Tips:
- It is helpful to also coat the stamps with release powder before placing on wet concrete for the first time.
- Never drag anything on the surface or trowel over release powder. Discoloration will occur.
- If the stamps have been recently washed, they must be fully dry before starting to stamp. Any moisture still left on the mats will decrease the release powder efficiency resulting on concrete adhering to the stamp.
- Always cover walls, columns and plants with 1 mill plastic liner to avoid excessive clean up labor.
- Before pressure washing the concrete, broom off the release powder or pick up with a wet vac.
- The release powder may also be removed without pressure washing by using a liquid soap and brooms to remove excess.
- If after pressure washing and cleaning there is still too much release on the surface a very mild water/muratic acid solution may be used to complete the removal. Use this process with caution.
- If too much release is removed you may antique the concrete with a liquid antiquing mix made with Concreation Clear sealer + solvent + release powder sprayed onto the surface.
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 need will depend on a number of factors including traffic conditions, geographical location and weather.
Caution:
Use face mask or respirator. Do not allow getting into eyes. Keep out of the reach of children. Prolonged breathing will cause throat and lung irritation. Protect all adjacent areas. See Material Safety Data Sheets for further information.
Shelf Life:
Indefinitely if protected from moisture.
Coverage:
1000 to 1200 square feet per 38-pound pail / 93 to 112 square meters per 17.24 kilogram pail. Coverage rates vary with application technique, wind conditions and texture of the concrete prior to application.
Packaging:
Pail, 38 pounds/17.24 kilograms.
Warranty:
CONCREATION POWDER RELEASE is warranted to be of uniform quality within manufacturing tolerances. Since control is not exercised over its use, no warranty, expressed or implied, is made as to the effects of such use. Seller and manufacturer’s obligation under this warranty shall be limited to refunding the purchase price of that portion of the material proven to be defective.
