• For use in living areas with intensive use and in commercial use with extremely increased mechanical and chemical stress.
• Stress class C according to ÖNorm C 2354.
• With the help of built-in nanotechnology, extremely fast further processing and usability of the sealed surface is guaranteed.The product has an extremely long pot life.
• The sealed surface can be sanded quickly.
• For indoor use.
• The product can be used on underfloor heating.
  
• In combination with 873 Aqua Varnish Additive R9 it achieves the slip class R9 according to German BGR 181.
• Complies with DIN EN 71-3. Safety of toys - migration of certain elements.
• Very low emission laying material according to EMICODE EC1 Plus.
• Emission tested building product according to DIBt principles. 
• Declared by baubook, "ecological building product".

• The surfaces to be sealed must be clean and free of residues of oil, wax, silicone and other adhesion-reducing layers.
• Joints are closed with suitable Eurocol joint sealant. The fine sanding depends on the type of wood. The surface and edge sanding must be levelled out by means of a sanding grid.
• Use a Eurocol primer with barrier effect (e.g. for exotic woods, smoked oak, etc.) or to minimise absorbency and edge gluing (e.g. upright lamella parquet, parquet on sprung floors or on underfloor heating).
• In case of defects, objections are to be reported in writing.

Before use, temper the product according to the processing conditions.

• Stir before use!
• The hardener LE (component B) has to be added completely to base (component A). Once fully added, stir the mixture for a minimum of 2 minutes until it becomes a homogenous mass. Allow it to react for 10 minutes and briefly shake again and homogenize. Add the appropriate lacquer to a mixing container. Use a scraper grid during application.
• Application to be done with a Eurocol stainless double-sided spatula 27 cm (after intermediate sanding) or a new, clean Eurocol Aqua microfiber roller 25 cm.
• The application to avoid any footprints on the floor.
• Do not apply more than two roller coats of lacquer in one day.
• Do not use the product after the end of the pot life. End of pot life ist not recognizable by viscosity change!
• To achieve uniform surface, apply the lacquer uniform with subsequent top coat application with roller.
• Eurocol recommends 2-3 roller applications.
• In the same day, do not apply the product more than twice.
• Drying time in-between layers is approx. 3 hours but not more than 24 hours.
• The surface needs to be sanded with an abrasive grid 100 or 120. Remove the dust with an industrial vacuum cleaner.
  Intermediate sanding improves the surface finish. Remove dust remains on the sanded surface.

During the drying process, even ventilation must be ensured. Draughts and direct sunlight must be avoided.

Rare woods, bleached ash, acacia, cherry, exotic woods or smoked oak must be primed with a blocking primer because of possible discolouration or streaking caused by ingredients or the smoking process.

Recommended primers:

Eurocol 883 Europrime Perfect   
Rollable and trowelable, Low side-bonding. High neutrality of the wood tinting. Long wet-on-wet workability (rollability). No visible seams during rolling and filling. 
Eurocol 857 Europrime Block     
Exclusively for rolling. Especially for exotic woods, smoked oak and for renovation work. Pronounced accentuation/wood tinting in woods that are sensitive to this, such as oak, beech, etc.

Working conditions:
Required surrounding temperature: min. 18°C.
Material and subfloor temperature: min. 15°C.
Relative humidity: 35 - 75%, recommended <65%.

To achieve the anti-slip class R9, add the homogenized Eurocol 873 Aqua lacquer additives to the 2k aqua lacquer after its homogenization and before the addition of the hardener and mix well by shaking, then add the hardener and proceed according to the application instructions of the lacquer. The mixture with aqua lacquer must be processed within the pot-life. In this case, the mixture must be shaken regularly to prevent the setting of the structural agent during processing.

When used as a topcoat on Eurocol 869 Eurofinish Oil Wax Duo, the oil must be cured for a minimum of 16 up to a maximum of 48 hours without stickiness, with good ventilation and at normal temperature. Lower temperatures or low air exchange delay the drying time of the oil. Also the use on critical woods, e.g. very resinous woods (see indications in technical data sheet Eurocol 869 Oil Wax Duo), can delay the drying time. In these cases, the intermediate drying time must be extended by approx. 6 hours.

Before applying the varnish, the surface must be rubbed with a green pad and dedusted.

Depending on the frequency of the floor traffic, several varnish applications with an intermediate drying time of at least 3 to maximum 24 hours must be made, but not more than 2 varnish applications per day.
