DUSTONE
COLOR RELEASE AGENT
Description and Uses: Dustone antiquing Release
is broadcast over the surface of freshly placed
colored-concrete hardscapes or interior floors before
imprinting with MATCRETE® or other type of
texturing tools or rollers. It forms a bond-breaking
barrier that helps prevent the tools
from sticking to the fresh concrete and marring its
fragile surface. During the process, a portion of the
Colored antiquing release becomes embedded in the
surface where it is trapped by the hardening concrete.
When the surface is subsequently washed and sealed, an
attractive, variegated, mottled, and antiqued appearance
is obtained with colors ranging from that of the
underlying concrete to that of the antiquing release,
with mixtures of the two the most likely.
To protect the antiqued appearance from wearing
or weathering away over time, the imprinted concrete
must be sealed and maintained with clear sealer.
It produces an attractive, low-maintenance, semi-gloss
film that is resistant to abrasion, many chemicals, and
surface staining. Joints should be sealed with
calking in a blending color to provide harmonious
transitions at the joint lines and allow the beauty of
the design to dominate and to keep excess water from
getting under the slab to help resist soil expansion or
cracking due to it.
Limitations: Dustone antiquing release is
not intended for use on vertical surface or for use as a
curing material, It should not be used as the primary
concrete-coloring agent, but must be applied over
freshly placed color-hardened or integrally colored
concrete. Dustone antiquing
release is intended to produce a variegated
appearance, Timing, finishing, application and removal
techniques, mix design, texture of the imprinted
pattern, color combinations, weather, experience in use
of the materials, sealing and other factors will
significantly affect the amount of antiquing ultimately
obtained and the final appearance of the antiqued
surfaces.
Enough material must be applied so that moisture
does not migrate to the surface, causing the texturing
tool or roller to stick. The powdered antiquing release
is very finely ground and should not be applied when
wind conditions are such that it may drift during
broadcasting or be displaced from the surface of the
concrete after application. Surrounding areas should be
protected to reduce the possibility of staining during
application.
Applicable Standards: The coloring materials in
antiquing release conforms to ASTM C 79 for color
stability. Professional concreting standards and
practices, including those published by the American
Concrete Association, should be followed. See
Application below.
Available Colors : Dustone antiquing release is
available from stock in colors approximating selected
colors from Dustone Color Release / Color Hardener
Chart. Due to dissimilarities in composition of
materials, these colors are similar to, but not an exact
match for colors. Unique
coloring and antiquing
effects are produced by using antiquing release in
a different and normally darker color than that of the
concrete surface. If less antiquing is desired, a color
that is more similar to the color of the concrete should
be chosen.
Product Sizes: Dustone antiquing
release is available in 33 pound (15kg) pails.
Coverage: Coverage will vary depending on timing,
method of finishing prior to imprinting, application
techniques, effect desired, tools used, and job or other
conditions. For most applications, the coverage rate is
approximately 3-4 pounds per 100 square feet (1.5-2.0
kg/10 m2). A more exact coverage rate can be determined
after producing Jobsite samples and noting the
amount of material needed per square foot. Usually
1000 sq. ft. per Pail.
Shelf life: under normal conditions and when kept
dry, the shelf life of antiquing release is at
least one year from the date of purchase . inventory
should be rotated.
Cautions: do not breath dust. Do not take
internally. Keep out of the reach of children. Use with
adequate ventilation, dust mask (niosh/msha tc 21c
approved), safety goggles, and gloves are recommended.
First
Aid: eyes-do not rub eyes. Immediately flush
thoroughly with plenty of water. Skin-Wash thoroughly
with soap and water. Remove soiled clothing.
Inhalation-move to fresh air. If symptoms persist or
develop, or if ingested, get medical attention. Wash
thoroughly immediately after handling. close container
after each use. Before using or handling, read all
applicable material and follow directions.
Jobsite samples. Producing antiqued, imprinted
concrete requires skill and practice. Timing, finishing,
application and removal techniques, mix design, texture
of the imprinted pattern, color combinations, weather,
experience in use of the materials, sealing and other
factors will significantly affect the amount of
antiquing ultimately obtained and the final
appearance of the imprinted, antiqued surface.
Representative jobsite samples should be produced and
approved prior to installation. For safety
considerations, the jobsite samples should be inspected
after completion to verify and approve the adequacy of
wet and dry slip resistance.
Antiquing Release Application:
Surrounding areas, landscaping, and adjacent
surfaces should be protected. The work area should be
roped off, nearby vehicles removed, and appropriate
sections closed to traffic. Application on a still day
is recommended, since the powdered antiquing release is
very finely ground, and wind conditions will severely
affect its application. The required pails of
antiquing release should be distributed around the
perimeter of the area to be antiqued. Immediately prior
to imprinting, the antiquing release should be
hand-broadcasted evenly across the surface by the
dry-shake method, normally in one broadcasting operation
(shake). To prevent drifting, the antiquing release
should not be broadcast for above knee level or for more
than a few feet, less under windy conditions.

To prevent adhesion during imprinting, a complete
and adequate layer of antiquing release should exist
between the concrete and the mat-type texturing tool or
roller. Sufficient
material should be applied so that the sheen disappears
form the surface of the concrete, but sine texture
details may be diminished, the application of an
excessive amount should be avoided.
Timing is critical to successful application. If
the antiquing release is applied while the slab is too
plastic, more material than desired my become embedded
in the concrete and difficult or impossible to remove,
causing the final color to be mostly that of the
antiquing release. If the antiquing release is applied
when the concrete is not plastic enough, little material
will be able to combine with the concrete and most of it
will be remove from the surface without producing the
desired color effect.
The finish applied to the surface of the concrete
prior to stamping will also affect the amount of
material that embeds in the concrete. Rough finishes
will retain more antiquing release than flat finishes.
Antiquing release removal: After the
imprinted concrete has been installed for a minimum of
1-10 days, the remaining un-embedded antiquing release
should be removed by a thorough rinsing off. Followed by
washing with a high pressure water sprayer, or a carpet
back or pad scrub, depending on desired finish.
An adequate area should be tested prior to
washing and rinsing the entire surface to insure that
the concrete is strong enough to resist damage and
scaling. Sufficient antiquing release should be remove
to obtain the desired effect. Care should be taken so
that adjacent surfaces are not stained, and runoff
should be controlled in accordance with local, state,
and federal regulations. All surfaces should be
thoroughly inspected to verify and approve installation
and safety prior to opening the area to traffic.
Sealing:
To seal and protect the antiqued surface, one or
two coats of Sealer must be applied.
Our Renew-Crete® sealer
is a premium-quality, environmentally compatible coating
that offers excellent durability while complying with
the most stringent air-quality requirements. It reduces
surface staining and is resistant to abrasion, deicing
salts, many chemicals, weather, and ultraviolet (UV)
radiation. It can
be applied by using a Sprayer Like our SP-35
Big Mouth. Care should be taken in
preparing the surface before application of the clear
sealer as the antiquing release may affect the adhesion
between the sealer and the color-hardened surface,
particularly if the non embedded material is not
adequately removed.
As soon as possible after the antiquing release
has been removed and after the moisture content of the
concrete is low enough so that alkali and other salts do
not become trapped beneath the sealer, normally 4-28
days after placement, one or two coats of sealer should
be applied evenly by airless sprayer at
the rate of
approximately 200-300 square feet per gallon
(7-10m2/L) per coat. The second coat if any should be
applied after the first coat is completely dry, a
minimum of 4-24 hours after application of the first
coat depending on temperature and humidity.
All surfaces should be thoroughly inspected to
verify and approve installation and safety, including
wet and dry slip resistance, prior to opening the sealed
surface to traffic.
