The present invention relates to a product (1) so arranged as to reduce the occurrence of so-called lime precipitation in connection with the application of rendering, surface colour finish or a combined product thereof, containing a hydraulic binding agent, to a facade (2) or some other similar surface, and as to permit the appropriately slow binding of the substances present in the product (1) in order to permit its manageable application along the intended application surface. The following are included in same according to the invention: a rapid-binding binding agent in the form of aluminous cement, preferably Lafarge R SEC 71, at a level of 5-30 percent by weight and filler at a level of 60-95 percent by weight. The binding process of the product is slow, in spite of the normally rapid-binding characteristics of the binding agent. The absent or low lime-precipitation characteristic of the binding agent is also utilized.
