Blender Color Hardener®


BLENDER COLOR HARDENER® is a manufactured prepared mixture which is ready to be used. BLENDER COLOR HARDENER® is an aggregate hardener of silica quartz, non-metal, that has been scientifically qualified. This aggregate has been designed specifically for early applications on concrete floors that require color and that will be stamped.

BLENDER COLOR HARDENER® may be applied on freshly placed concrete. Blender Color Hardener® has been made to be applied in concrete plastic conditions with ranges of up to 0.6 lb/ft² (3 Kg/m²), although it may be applied with higher ranges if a sample is realized previous to application.

Basic use: BLENDER COLOR HARDENER® is durable, it does not leave spots nor does it rust. It may be used on concrete works like pavements, streets, avenues, boardwalks, garage flooring, hallways, walking aids, malls, hotels, buildings, and in general areas where there is a color specification and abrasion resistance required.

BLENDER COLOR HARDENER® is available in polyethylene reinforced bags of 60 lb (27 Kg). The standard range of application of BLENDER COLOR HARDENER® is from 0.4 to 0.6 lb/ft² (2 to 3 Kg/m²), that is to say 107 ft² (10m²) per container of 60 lb (27Kg). The theoretical performance in lighter colors diminishes between 10% and 15%, consult the local representative of Blender Group® for a specific recommendation in order to satisfy your individual needs.


Standard Method ACI 302:

● This method may be used if BLENDER COLOR HARDENER® will be applied by hand or with a spreader.
● The concrete should be cleared and smoothed before the emergence of bleed water. The smoothing tool of the surfaces is a magnesium trowel.
● After the concrete bleding, BLENDER COLOR HARDENER®, has to be distributed evenly in approximately ⅔ of the product over the specific area. If the hardener breaks throughout the surface while being applied, this indicates that the concrete is too plastic for this product.
● When the material briefly darkens due to the absorbed humidity, this should be integrated using an aluminum or magnesium trowel (do not use both trowels). Be careful not to tear the inferior concrete surface of the BLENDER COLOR HARDENER®.
● Do not apply more BLENDER COLOR HARDENER® until the humidity of the concrete helps covering the material of the first layer of the BLENDER COLOR HARDENER®.
● Apply immediately after ⅓ of the product, which is the remaining amount of specified hardener and the first application is preferably applied in a perpendicular form.
● The existing humidity in the concrete should cover the second application 100%, otherwise the floor will delaminate.
● Allow the shading caused by the humidity and smoothen.
● Once the concrete has been colored in a homogeneous way and in case of a stamped concrete proceed to the application of the BLENDER REALEASE AGENT® once the concrete surface has the sufficient plasticity that allows you to leave a finger mark.

Curing: If it is not a Stamped Concrete job use the curing surface methods used for conventional concrete. (Consult the local Blender Group® representative for further instructions)


For situations of extreme heat or windy conditions, it is recommended to utilize an evaporation control method or product. This will help avoid cracks from plastic contraction and it will give a longer work time to the surface without the use of extra water which furthermore provokes irreversible damages to the resistance of your Concrete. (Ask for more information regarding this type of products with the Blender Group® representative).

In windy conditions, locate partitions to diminish the direct wind attack which will help prevent the loss of the product and by default a low efficiency of such.

– Do not locate the concrete over a dry subgrade.
– Do not utilize air-entrainment agents.
– Do not use admixtures, aggregates, and water mixtures that contain chlorides in the target concrete.
– Avoid the rain or drizzle over the product for at least the first 24 hours. Otherwise, cover the surface with plastic to avoid spots or unwanted marks.
– Blender Group® is not responsible for delaminations, breakdown, cracks or resulting pores of an inappropriate application of the finish.
– The work conditions that influence the drying of the surface and the concrete setting time can affect the application time of the BLENDER COLOR HARDENER® and the finishing procedures.
– To lengthen the life of the BLENDER COLOR HARDENER®, seal the surface BLENDER SEAL ACRYL® 30% or BLENDER SEAL ACRYL® WB.
