EXTRATOP® ENDURO Ultrametallic hardener for industrial floors CT‐C60‐F10‐A1,5OPIS PRODUKTU DESCRIPTION EXTRATOP® ENDURO ‐ an ultrametallic, dry shake topping (DST) for monolithic concrete floors. It contains hard aggregate, high‐performance cements and proper admixtures and pigments. Applied and troweled on freshly‐made concrete, it creates a coloured, marble‐like, abrasion and dusting resistant, smooth floor of increased resistance to the penetration with oils, grease etc. ZASTOSOWANIE  Making of new surface‐hardened floors of very high hardness and   resistance to abrasion and dusting in facilities of extreme usage con‐ ditions – steel and power plants, factories, logistic centres etc. Anti‐electrostatic floors Making of floors in potentially explosive areas. Easy to clean Sealed and non‐dusting surface Frost‐resistant Wide range of colours Highest dusting resistance Highest impact resistance CONCRETE SLAB EXTRATOP ENDURO is used on surfaces of freshly‐made low‐shrinkage concrete:  class C20/25 or higher  w/c ratio ≤ 0,50  amount of cement ≤ 350 kg/m3  alkali contents in cement <0,5%  cement CEM I, CEM II/A‐S, CEM II/B‐S or CEM III/A  aggregate ≤ 16 mm  contents of fraction ≤ 0.25 mm ‐ min. 4%  sand point about 35%  total amount of cement and aggregate of fraction ≤0.25 mm – max. 450 kg/m3  addition of steel fibres BAUMIX and polypropylene fibers BAUCON by recommendation of BAUTECH ‐ if an anti‐electrostatic floor is being made, the concrete must have an addition of BAUMIX steel fibres in the amount of no less than 20 kg/m3; also a discharge of electrical charges must be performed.  consistence on the construction site: S3, Abrams cone slump about 12 cm. Addition of steel fibres decreases the slump. In case of outdoor surfaces, concrete of exposure class XF4 should be used. CAUTION! Do not add any volatile ashes, as these tend to accumulate in the top layer of the slab, which may cause the dusting of the floor or detachments of the hardenER. It is forbidden to add water to concrete mixture in order to increase its workability. This causes a significant loss of the strength of the concrete and a clear increase of the chemical and physical shrinkage, leading to the creation of uncontrolled scratches and cracks. The concrete must be properly compacted. APPLICATION CONDITIONS The temperature of the ambient and foundation during the works and for the next 5 days should be between +5°C and +30°C. The surface made should be protected from losing water too quickly as a result of, for example, high temperatures, draught, sunlight operation etc. In order to ensure high quality and uniform colour, all works should be performed with suitable tools in an area protected from dust, EPS balls and similar impurities. METHOD OF USE Before surface hardener EXTRATOP ENDURO is used, the concrete must achieve proper hardness. The setting time of concrete depends on the temperature, relative humidity of the air etc. The surface of the concrete must not get too hard, therefore its condition must be frequently checked. As a result, selection of the optimal moment to begin applica‐ tion of the surface hardener will be possible. The works may be com‐ menced when the imprints of feet on the concrete are not deeper than 3‐4 mm. Remove excess of cement paste from the surface of the con‐ crete with rubber squeegees and refresh the surface with a disc. Then spread about 3,5 kg/m2 of EXTRATOP ENDURO hardener. Perform rough troweling of the surface with a disc, spread the hardener again, in the amount of about 3,5 kg/m2 and trowel the whole of it once more with a disc. The amount of spreaded hardener is about 7.0 kg/m2. Continuously control the consumption, as careless distribution of the hardener may decrease the quality of the floor. Perform the subsequent stages of troweling with blades set gradually at increasing angles. CURING Immediately after the troweling is completed, the whole surface should be treated with a selected preparation in order to prevent too quick loss of water: BAUSEAL® EKO A water‐diluted sealer for industrial floors applied with the spraying method, with a low‐pressure sprayer. Sealer should be applied once, with a thin layer, paying attention that no puddles are left. Efficiency: 1 litre per 8‐12 m2 BAUSEAL® ENDURO A solvent‐based sealer for industrial floors applied on freshly made con‐ crete floor, immediately after the last mechanical troweling is done. Sealer should be applied with the spraying method, with a low‐pressure sprayer. Sealer should be applied once, with a thin layer, paying attention that no puddles are left. Efficiency: 1 litre per 8‐10 m2 BAUTECH FORMULA® Silicate and polymer based agent for the maintenance, strengthening and sealing of concrete surfaces. BAUTECH FORMULA should be applied evenly on the surface with the spraying method in the amount of 0.1 ‐ 0.2 l/m2 until complete coverage is obtained. The surface should stay wet for 15 ‐ 20 minutes. An additional amount of the agent should be applied in places where it dries up faster – a microfi‐ ber mop helps distribute the agent evenly

The mixture contains cement ‐ mixed with water gives an alkaline reac‐ tion. Avoid breathing, protect eyes and skin. In case of contaminations: clean eyes with plenty of water, wash skin with soap and water. Working areas should be ventilated. Keep away from the children.
