DESCRIPTION
FEATURES
AND BENEFITS:
DECOSUP LIQUID Integral colors are pure natural
or synthetic pigments with no fillers or artificial adulterants.
Consistently uniform from pail to pail, their extremely small particle
size gives them the highest possible tinting strength. They are
light fast, lime proof and weather resistant. DECOSUP colors meet
ASTM C-979 and are formulated for mix-in only.
USES:
Architectural Block, Cast Stone, Decorative and Imprinted Concrete,
Poured in place Concrete, Freeway Sound Barriers, Sidewalks, Landscaping
and many other applications
KEYS
TO SUCCESSFUL COLORED CONCRETE:
The key to successful colored concrete results is adherence to approved
concrete practices. Successful colored concrete requires more attention
to detail, proper planning and above all UNIFORMITY than standard
gray concrete. Uniformity of raw materials, site conditions, placing
and finishing methods and curing are extremely important for quality
concrete applications. The color should be accurately measured by
weight or volume. Thorough mixing of the color with the other ingredients
is necessary for consistent uniform color
BATCHING,
PLACING, FINISHING AND CURING OF READY MIX CONCRETE:
The same cement aggregates, sand and water source should be used
throughout the job. At the batch plant add the color by weight directly
to the mixer along with the aggregate, cement and water while the
mixer is operating at the mixing speed. Continue mixing 5-10 minutes
or from 50-100 revolutions. Make sure the pigment to cement ratio
remains the same for all mix designs. Maintain a 4”-5”
slump, ALL CONCRETE SHOULD BE PLACED AT THE SAME SLUMP. The addition
of water to the mix will result in light or washed out spots. Place
all colored concrete in a uniformly graded, compacted and damped
surged. Use the lowest slump compatible with a workable, placeable
mix. Troweling may begin after the disappearance of bleed water
from the surface.
Be sure the concrete is stiff yet plastic before troweling or brooming.
Late or hard troweling will cause burning, light broom finish is
recommended, and will less likely discolored than smooth finishes.
Do not add pigment, cement or water to the fresh surface of the
concrete. Excess water should be removed from broomed surface before
contact is made with fresh cement. A non-yellowing curing and sealing
compound should be lightly sprayed on immediately following final
finish.
LIMITATIONS:
Inconsistencies in concrete mix, water cement ratio, batch to batch
slump, job site conditions, finishing practices, and curing methods
may produce variations in the color of the finished product
CAUTION:
Variation of color can occur when the actual job-site materials
and individual finishing methods are applied. Lighter or deeper
shades can result by varying the weight or color, pigment use d
or the color of cement and sand used on the job. The addition of
fly ash to the mix can also result on a color variation. Changes
on the water to cement ratio or water added at the job site will
affect the final color of the concrete. A test pad should always
be poured using actual job-site materials and conditions. Calcium
Chloride accelerator should not be used with any pigment. The use
of Calcium Chloride may result in uneven coloring and spots (bleached-out
areas). Evaporation of water sometimes leaves a white powdering
film (efflorescence) on the surface of the concrete. Soluble salts
present in the water or aggregate escaping to the surface cause
efflorescence. It’s common in standard gray concrete. Although
it is not as noticeable as in colored concrete. To avoid efflorescence
always be sure water and aggregates are clean and free of soluble
salts.
