DUROCRET-DECO FINISH is a premixed, polymer-modified, decorative microcement coating, without corrosive ingredients, suitable for indoor and outdoor applications, offering:
- Smooth final surface
- Abrasion resistance
- Excellent adhesion to the substrate
- A special aesthetic result
Certified according to EN 1504-3 and EN 13813, classified as a PCC R 3 mortar for concrete repair and as a screed material CT-C25-F6-AR2, respectively. CE marked.
DUROCRET-DECO FINISH is used as a microcement coating in numerous applications, such as stairwells, floors, walls and special constructions, such as built-in beds, built-in sanitary ware ( wasbasins, showers, etc). For interior and exterior applications in houses, hotels or wherever a special aesthetics result is desired. Applicable in thin layers (1-3 mm), in most cases as a final coating over DUROCRET-DECO and DUROCRET-DECO FLEX, to deliver a smooth surface.
Substrate preparation
The substrate should be clean, free of dust, oil or grease, loose material, etc. Before applying DUROCRET-DECO FINISH to 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 absorbency of the substrate. DUROCRET-DECO FINISH is applied after 2-3 hours, depending on the weather conditions, provided that the primer has sufficiently dried. Gypsum board surfaces should be first primed with UNI-PRIMER; and then DUROCRET-DECO FLEX should be applied as a base coat, reinforced with 160 g/m2 fiberglass mesh. Twenty-four hours later, the hardened surface of DUROCRET-DECO FLEX is primed with UNI-PRIMER and while is still fresh DUROCRET-DECO FINISH may be applied (fresh on fresh). Non-absorbent substrates such as old tile layers or terrazzo should be primed with SUPERGRUND. DUROCRET-DECO FINISH may be applied 24h later as long as the primer has completely dried.
Application
DUROCRET-DECO FINISH is gradually added to water under continuous stirring, until a mixture of desired workability is formed. The product is applied with a smooth trowel at a thickness of 1-3 mm in 1 or 2 layers. After hardening, ti 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 varnish may be applied.
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-matt). 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 is soaked, then drain it in the paint tray and apply it on the surface. VARNISH-PU 2K (gloss or satin) in two 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 the intens darkening of the microcement surface caused by VARNISH-PU 2K. Also, the use of VS-W can significantly improve the final surface appearence of the microcement when used diluted with water 1:1, in one layer, prior to the application of VARNISH PU-2KW water-based varnish.
