Technical Leaflet DUROCRET-DECO is a pre-mixed, polymer-modified, fiber-reinforced microcement coating, without corrosive ingredients, suitable for indoor and outdoor applications, on floors and walls, offering: • Abrasion resistance. • Very good bonding to the substrate. • Water repellency. • A special aesthetic result. It is classified as a PCC R2 mortar for concrete repairs, according to EN 1504-3. DUROCRET-DECO is used both internally and externally, in numerous applications, such as stairs, floors, walls, as well as wherever a special aesthetic result is desired (e.g. Cycladic architecture). Also used in houses, stores, hotels etc. and special constructions, such as built-in beds, built-in sanitary ware (washbasins, showers etc.). Form: cementitious powder Colors: white, grey, light grey, light Bulk density of dry mortar: 1.45 ± 0.10 kg/l Bulk density of fresh mortar: 1.80 ± 0.10 kg/l Compressive strength: > 22.0 N/mm2 Flexural strength: > 6.0 N/mm2 Thermal compatibility Part 1 (50 freeze-thaw cycles): > 1.2 N/mm2 Application thickness: 2-10 mm per layer Capillary water absorption: 0.34 kg-m-2-h-0'5 Reaction to fire: Euroclass A1 1. Substrate preparation The substrate should be clean, free of dust, oily or loose materials, etc. Any cavities such as cracks or holes in the substrate should be properly filled. Before applying DUROCRET-DECO on absorbent substrates, such as masonry, concrete, plaster, gypsum board, they should be first primed with the acrylic primer UNIPRIMER in 1-2 layers, depending on the absorptivity of the substrate. DUROCRET-DECO is applied after 2-3 hours, depending on the weather conditions, provided that the primer has sufficiently dried. Non absorbent substrates, such as old tile layers or mosaic, should be primed with the primer ISOMAT SUPERGRUND. DUROCRET-DECO may be applied after 24 hours, as long as the primer has completely dried. 2. Application On walls: DUROCRET-DECO is gradually added to water under continuous stirring, until a mixture of the desired workability is formed. The product is applied with a 10 mm notched trowel. A 160 g/m2 reinforcing fiberglass mesh is installed on the 'combed' surface of DUROCRET-DECO, which is then embedded with the smooth side of the trowel, forming a relatively even surface. Twenty-four hours later, the hardened surface of DUROCRET-DECO is primed with the acrylic primer UNI-PRIMER. While the primer is still fresh (fresh on fresh), DUROCRET-DECO or DUROCRET-DECO FINISH is applied in a thin layer (1-2 mm) in any desired color, in order to form the desired style of the microcement coating .

On floors: The application is the same as the one on walls - the only difference is that ADIFLEX-B building resin should be added in the mixture, in a quantity of 1-2 kg per 25 kg of DUROCRET-DECO. In that case, the mixing water should be reduced, as much as is necessary in order for the mixture to acquire the desirable workability. Alternatively, DUROCRET-DECO FLEX, the flexible microcement coating that does not need to be reinforced with resin, may be used instead of DUROCRET-DECO. On walls made of gypsum board or cement board, DUROCRET-DECO will have to be reinforced with ADIFLEX-B. One...

• Instead of UNI-PRIMER, FLEX-PRIMER or ADIFLEX-B resin diluted with water (1:2) may be used. • Temperature during the application should be between +5°C and +30°C. • In the summer, it is recommended to take the proper measures in order to protect DUROCRET-DECO from water loss, due to high temperatures. • The product contains cement, which reacts with water, forming alkaline solutions, thus is classified as irritant. • Consult the directions for safe use and precautions written on the package.
