for Release Powder Ideal for clean release of patterns in textured concrete
QC Release Powder II is specifically designed for use with color hardened textured concrete
QC Release Powder
The original QC RELEASE POWDER is specifically designed for use with color hardened textured concrete. This product allows for the clean release of texturing tools from the concrete surface, and at the same time, creates highlighting color (also called an antiquing effect) with mat-type texturing tools. QC RELEASE POWDER II can be used with all textured concrete.
QC Release Powder Uses and Benefits
RELEASE POWDERS - dry-mix formulated powders and color pigments - are designed for the clean release of mat-type texturing tools.
These products add color-embedded variation to the textured surface, providing highlighting and antiquing effects that closely resemble natural material.
QC RELEASE POWDER is available in 25 standard colors. See QC COLOR HARDENER and RELEASE POWDER Chart. Custom colors are also availble, with no minimum orders required..
1. The surface is ready for release once concrete reaches the point when no bleed water remains on the surface and when concrete is sufficiently firm to withstand texturing tools and the weight of a work crew. QC RELEASE POWDER should be evenly hand-broadcast over the entire surface of freshly placed concrete. An alternative application method is to spread QC RELEASE POWDER with a long-handled scrub brush in order to achieve light, uniform coverage.
2. QC RELEASE POWDER should remain in a dry state on the concrete surfacethe product should not be worked into the surface. Care should be taken not to trowel the powder into the wet concrete. Troweling powdered release into the surface will result in permanent discoloration.
3. QC RELEASE POWDER may be removed as soon as the concrete has hardened to the point that it will not scratch or mar easily (normally two to three days). Pressure-washing the surface is the typical removal method. For hard-to-remove release or for heavy texture work with release, a mild muriatic solution may be used (15 parts water: 1 part muriatic acid).
Curing and Sealing Concrete
1. For curing concrete treated with QC RELEASE POWDER, new, nonwrinkled, nonstaining, reinforced, kraft-curing paper should be used.
2. After release has been washed from the surface and once concrete has dried to a uniform color, sealing the concrete may take place. For sealing concrete, choose from a variety of QC sealers appropriate to project requirements: QC CEMSEAL, QC SOLVENT-BASED SEALERS, or QC SURPRO WB or SB. (See separate Product Information Bulletins for complete instructions on these products.)
It is highly recommended to develop and follow a routine maintenance schedule for all colored concrete so that it maintains a top-quality appearance. Colored concrete installations should be routinely inspected, cleaned and resealed as local conditions demand. Cleaning and resealing schedules will depend on a number of factors including, but not limited to, volume and intensity of traffic, maintenance procedures and weather.
Inconsistencies in job site conditions, finishing practices, timing of imprinting, and curing methods may produce variations in the color of the finished product.
QC RELEASE POWDER may be used on vertical faces of step risers and curbs.
Note - Actual coverage may vary depending on color choice, application method, concrete surface finish, wind conditions, and other local conditions.
All Colors - 1,000-1,500 square feet per 30-pound pail.

3.01 Installation Procedures
a. The area to receive imprinted concrete shall have the subgrade prepared as required as for any concrete slab on grade.
b. The formwork shall be installed in accordance with the drawings. The slab thickness shall be consistent with that of ordinary concrete slabs under the same conditions.
c. Provide reinforcement as specified.
d. Control joints and/or expansion joints shall be provided in accordance with the drawings and the guidelines established by the American Concrete Institute. As with any concrete slab, imprinted concrete usually contains construction joints, control joints, and expansion joints. The contractor shall advise and work with the architect/engineer to determine the best location for these joints to minimize the visibility of the joints and to minimize unsightly cracking.
e. The concrete shall be placed and screeded to the finished grade and floated to a uniform surface using standard finishing techniques.
f. QC COLOR HARDENER shall be applied evenly to the surface of the fresh concrete by the dry-shake method using a minimum of 60 pounds per 100 square feet. Lighter colors and commercial/industrial applications may require heavier application rates. Consult the QC COLOR HARDENER Product Information Bulletin for coverage guidelines. It shall be applied in two or more shakes, floated after each shake, and troweled only after the final floating.
g. (Optional) QC RELEASE POWDER shall be applied evenly to the troweled surface prior to imprinting.
h. All imprinted surfaces shall be cured and/or sealed with QC CURES and SEALERS, depending on the architectural specifications and application. Consult the respective QC Product Information Bulletin for complete product information and application instructions.
