Abstract
Protective and decorative coatings of about two mills and greater thickness are produced from hydraulic cement slurries formulated with finely divided mineral aggregates, a film-forming synthetic polymer latex, a 'super' water reducer, and a rust inhibitor. These constituents are formulated into liquid and powder components which are mixed prior to spraying or brushing to produce the coating. The coatings are non-burning and are applicable for interior and exterior use. Very fast set of the cement are obtainable by admixing an accelerator to either the liquid or powder component and mixing the two components continuously by passing through a static in-line mixing device located in a feed line duct just before a spray nozzle.
