Abstract: The present invention provides compositions and methods which are adapted to impart color to concrete or mineral substrate surfaces. Specifically, the present invention relates to a composition and methods adapted to treat concrete surfaces which have the advantage of using a non-corrosive acid-based solution.

Abstract: The present invention provides acidic compositions and methods that are adapted to impart color to cementitious or mineral substrate surfaces. Specifically, the present invention relates to acidic compositions and methods adapted to treat cementitious or mineral substrate surfaces that have the advantage of using a less corrosive acid-based solution. The acidic composition incorporates species including a weak base in equilibrium with a conjugate acid. The presence of such species moderates the corrosive behavior of the acid while still allowing excellent coloring action to occur.

Abstract: A concrete cleaning and preparation composition is described, which includes urea hydrochloride, surfactant, water, and one or more glycol ethers. Also described is a method of preparing a concrete surface, including pre-wetting a concrete surface, using a cleaning and preparation composition, including urea hydrochloride, a surfactant, water, and one or more glycol ethers, and rinsing the concrete surface. Furthermore, a kit for cleaning, preparing, and coating concrete including a cleaning and preparation composition including urea hydrochloride, and a coating is also described.
