 Substrate preparation

The substrate should be clean, free of dust, oily or loose materials etc. Before applying DUROCRET-DECO FINISH on absorbent substrates, such as masonry, concrete or plaster, they should be first primed with the acrylic primer UNI-PRIMER in 1-2 layers, depending on the absorptivity of the substrate. DUROCRET-DECO FINISH is applied after 2-3 hours, depending on the weather conditions, provided that the primer has sufficiently dried. On gypsum boards, the surface should be first primed with UNI-PRIMER; then, DUROCRETDECO FLEX should be applied as a base coat, reinforced with 160 g/m2 fiberglass mesh. 24 hours later, the hardened surface of DUROCRET-DECO FLEX is primed with UNI-PRIMER and while the resin is still fresh (fresh on fresh), DUROCRET-DECO FINISH may be applied. Non absorbent substrates, such as old tile layers or mosaic should be primed with ISOMAT SUPERGRUND primer. DUROCRET-DECO FINISH may be applied after 24 hours, as long as the primer has completely dried.

Application

DUROCRET-DECO FINISH is gradually added to water under continuous stirring, until a mixture of the desired workability is formed. The product is applied with a smooth trowel in a thickness of 1-3 mm in 1 or 2 layers. After it hardens, it can be optionally sanded, depending on the required smoothness of the final surface. Two or three days after the application - provided that the surface is dry - the protective varnishes may be applied.

Coloring DUROCRET-DECO FINISH

DUROCRET-DECO FINISH is available in 6 ready-mixed colors (white, grey, light grey, light ocher, mocha, crocus). It may also be colored with DECO COLOR high-quality inorganic pigments. DECO COLOR pigments are available in 10 colors and may be combined to achieve an unlimited number of colors. There are 96 combinations indicatively recommended and presented in DECO COLOR SYSTEM, with a lot more potential tones available to the end user. In order to achieve better mixing, the pigment should be dissolved in the mixing water, before the mortar is added. It is also possible to add the pigment after the mortar has been mixed with the water, but in that case, it should be thoroughly mixed, in order to avoid uneven coloring of the mortar.

Application of the varnish

The microcement coating is protected with the application of the polyurethane, solvent-based varnish VARNISH-PU 2K (gloss or satin) or the polyurethane, water-based varnish VARNISH-PU 2KW (satin-mat). The water-based varnish is ideal for interior, poorly ventilated spaces, as it is almost odorless. VARNISH-PU 2K and VARNISH-PU 2KW are applied with a roller in two layers. The second layer is applied 4-24 hours after the first one, as long as it has sufficiently dried. Consumption: 70-120 g/m2 per layer. For better distribution of the varnish, it is recommended to dunk the roller in the varnish until it is soaked, then drain it in the paint tray and apply it on the surface. VARNISH-PU 2K (gloss or satin) generally darkens the surface. In case this is not desirable, it is recommended to combine two varnishes in the following way: First, the acrylic, water-based varnish VS-W (diluted with water 1:1) is applied in one layer at a consumption of 150-200 ml/m2 . After 24 hours, the polyurethane varnish VARNISH PU-2K (gloss or satin) is applied in 2 layers. The second layer is applied 4-24 hours after the first one, as long as it has sufficiently dried. The use of VS-W prevents intense darkening of the surface of the microcement coating, caused by VARNISH-PU 2K.
