TEKNOFLOOR AQUA

Clean new surfaces from dust and dirt. Wash previously painted surfaces with RENSA SUPER paint cleaner. Matt down hard or gloss surfaces by sanding and thereafter remove the dust. NEW CONCRETE SURFACES: The concrete must be at least 4 weeks old and well-hardened so that all moisture from casting is bound and the surface dry. The moisture of the concrete must not exceed 97% as relative humidity or 4% by weight (by 54 / BLY 12). Remove dense laitance from steel trowelled concrete surface by sanding or etching. Sanding is the best method for removing laitance. Brittle and powdery surfaces are sanded until hard ballast layer appears. After sanding the cement dust is vacuumed or brushed away. The surface is etched if sanding can not be performed. Use RENSA ETCHING Etching liquid or diluted hydrochloric acid (1 part hydrochloric acid and 4 parts water). After the etching the floor is rinsed with water and allowed to dry. OLD CONCRETE SURFACES: Unpainted greasy floors can be cleaned by emulsifying wash. After the emulsifying wash the floor is acid etched if it is covered with laitance. Loose and poorly adherent old paint coats and laitance can be removed by scraping or machine grinding. Wash previously painted surfaces with RENSA SUPER paint cleaner. Matt down hard or glossy surfaces by sanding and remove the dust. NEW WOODEN SURFACES: Untreated wooden surface is cleaned and/or sanded even, if required. Sanding dust is removed. OLD WOODEN SURFACES: Untreated wooden surface is cleaned and/or sanded even, if required. Sanding dust is removed. Remove loose and poorly adherent old paint coats by scraping or machine grinding. Wash previously painted surfaces with RENSA SUPER paint cleaner. Matt down hard or glossy surfaces by sanding and remove the dust. FILLING and SMOOTHING: If required, holes and other irregularities can be filled with TEKNOFLOOR-KOVAKITTI Epoxy Putty or a cement-based filler which suits the hardness of the surface. Wooden surfaces are smoothed with putties that are intended for wood.

Stir thoroughly before use. Apply once or twice. Suitable airless nozzle size 0.015 - 0.019".

The surface to be treated must be dry. During the application and drying period the temperature of the ambient air, the surface and the product shall be above +10°C and the relative air humidity below 80%. Drying is faster in low air humidity and/or above + 21 °C. Application will be easier if air is humidified and/or temperature is lowered in the working space. Ventilation after the painting will quicken the drying.

Must not freeze.
