QUIKRETEÂ® Concrete Resurfacer is cement gray in color and can be. colored with QUIKRETEÂ® Liquid Cement Color (#1317) or with other. pigments approved for use in concrete and masonry products. QUIKRETEÂ® Concrete Resurfacer has been designed to match. typical concretes in color. Concrete colors vary. Compare color by. mixing a small amount, placing it in an inconspicuous area, and. allowing it to fully harden before proceeding with the entire project. Concrete color will also vary depending on water added and. variations in the underlying concrete.
The stain may not reveal its true color until it has been allowed to remain on the concrete for several hours or longer. Although acid stains are available in limited color selections, you can mix two or more stain colors before application to achieve a different shade or apply one color over another. You can also produce deeper color effects with a stain by making two applications. Water-based stains can also be mixed to achieve custom hues and often are used in conjunction with acid stains to add highlights or expand the color palette. But be sure to check with the manufacturer for compatibility.
