DESCRIPTION AND BASIC
USE • MATCRETE® Dustone Antique Release Agent™ is a very fine colored
powder formulated for use in the texture stamping of concrete. It
improves results by preventing transfer of the wet paste when the tools
are removed to create beautifully antiqued and imprinted concrete
surfaces. Dustone Antique Release Agent is broadcast over the surface of
freshly placed colored concrete prior to imprinting, forming a bond
breaking barrier that helps prevent the tools from sticking to the fresh
concrete and marring the imprinted pattern in its fragile surface. During
the process, a portion of the colored antiquing release becomes embedded
in the surface, usually where there is relief in the texturing tool,
where it is trapped by the hardening concrete. When the surface is
subsequently washed and sealed a mottled, 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.
STORAGE • Store in
a cool, dry place, away from oxidizers and acids. Keep containers tightly
sealed. Shelf life is approximately 12 months.
COVERAGE • Coverage requirements 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 kilograms per 10 square meters).
PREPARATION • Before applying Dustone Antique Release Agent,
protect all surrounding areas where color is not desired.
APPLICATION
• Application on a still day is recommended, since Dustone Antique
Release Agent is very finely ground, and wind conditions will severely
affect its application. The required pails of Dustone Antique Release
Agent should be distributed around the perimeter of the area to be
antiqued. Immediately prior to imprinting, the antiquing release agent
should be applied using a soft, long-bristle masonry brush to broadcast
the material evenly across the surface, normally in one broadcasting
operation (shake). Hand-broadcasting will cause clumps of antiquing
release material to form on the concrete surface and is not recommended.
To prevent drifting, the antiquing release should not be broadcast from a
point above knee level. To prevent adhesion during imprinting, a complete
and adequate layer of Dustone Antique Release Agent should exist between
the concrete and the mat-type texturing tool or embossing skin.
Sufficient material should be applied so that the sheen disappears from
the surface of the concrete, but since texture detail may be diminished,
the application of an excessive amount should be avoided. Timing is
critical to successful application. If the antique release agent is
applied while the slab is too plastic, more material than desired may
become embedded in the concrete and be difficult or impossible to remove,
causing the final color to be closer to that of the antique release
agent. If Dustone Antique Release Agent 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 removed 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 antique release agent than
flat finishes. Troweling Dustone Antique Release Agent into the surface
will result in permanent discoloration.
REMOVAL • To reduce tracking and staining of other areas, excess
antique release agent may be removed by brooming or vacuuming the
imprinted concrete surface after it is hard enough to walk on without
marring. After the imprinted concrete surface has hardened sufficiently,
the remaining unembedded antique release agent should be removed to the
degree desired, using high-pressured water, by scrubbing or by buffing.
Care must be taken not to damage the curing, colored concrete surface.
The amount of Dustone Antique Release Agent adhering to the concrete
surface will depend upon how hard the concrete surface was at the time of
application and texturing. A softer surface will retain more antique
release agent than a harder one.
