Area of application: • ASO®-EZ4-Plus is a fibre-reinforced pre-blended factory produced mortar for producing water repellent cement-based screeds, which develop high early strength and can receive floor finishes early. Can be used for bonded, unbonded or floating quick setting screeds as well as for heated screeds as a wearing surface or a substrate for tiles, slabs, textile flooring, parquet or vinyl. Due to its water repellent properties, ASO®-EZ4-Plus offers increased protection against frost damage and efflorescence when used as a rapid hardening mortar bed for the installation of natural stone, tiles and slabs in exterior and wet areas, on balconies, terraces, loggia, steps, in swimming pools, wet rooms, car washes and water containers.

Product preparation: For mixing we recommend the use of suitable mechanical equipment, batch mixers, screed mixers with a 65 mm pipe diameter or other conventional screed mixers e.g. PFT, Putzmeister Mixocret or similar. Pay attention to the moisture content of the aggregate and avoid excess water. The working time is approx. 60 minutes at +20° C. Mixing, application and finishing must follow each other swiftly. Only measure out areas that can be completed within this working time. For bonded screeds firstly brush ASOCRET-HB-flex onto the prepared, e.g. mechanically abraded, concrete substrate. Lay the screed into the wet slurry coat.

*2) R eductions in thicknesses are possible as a result of structural calculations and measurements by means of product characteristics. Application: The substrate must be dry, load-bearing, adequately flat, free from penetrating cracks and free from separating substances such as e.g. oil, paint, laitance layers and loose components. It must have a largely closed surface texture and a surface condition and strength commensurate with its type. For application and installation, the general guidelines for cementbased screeds in accordance with DIN 18560 and DIN 18353 are applicable.
