摘要

A colour rendering and/or colour finish product (1) for use on a facade (2) or similar surface and contg. a hydraulic mineral binding agent in the form of aluminous cement, e.g. Larfarge (R) SEC 71, of 5-30 percent by weight and filler of 60-95 percent by weight, such that the binding process for the prod. despite rapid-binding characteristics, is slowed down, and low line levels result in elimination or reduction of line pptn. in the prod. The filler comprises dolomite, calcite, feldspar, sard, pearlite, wollastonite and cenospheres. Additives that extend the open time and additives which control the setting process are included.
