Before applying the pressed cement mortar, on cement-plaster-aggregate materials, first prime with Decor Primer. For application on other more difficult substrates, such as glass, ceramic tiles, metals, ask for the appropriate primer.
For application, use a stainless steel spatula in two or three layers of approximately 1mm thickness each. Each layer when dry is sanded with a mechanical sander (dust between layers and then apply the next). The two layers can be of the same or different color in order to achieve a different aesthetic effect. The last layer is also sanded with a mechanical sander in order to bring out the different shade of the first layer. After 1-2 days (after the surface has dried well) apply 2-component water acrylic varnish.
