Streetscape® Sopro HSF 748 Flexible Bonding Slurry with Trass

Streetscape® Sopro HSF 748 Flexible Bonding Slurry with Trass is a one-component, trass-bearing, polymer-modified bonding and contact slurry for laying ceramic tiling, natural and cast stone coverings, and paving units. Low-chromate to Regulation (EC) No 1907/2006, Annex XVII.

Sopro HSF 748 is a trass-bearing, polymer-modified, cementitious bonding slurry, offering smooth, easy workability and suitable for indoor and outdoor applications. Sopro HSF 748 promotes a strong bond between absorbent and non-absorbent coverings and bedding adhesive or between substrate and bedding adhesive/screed. When fully set, Sopro HSF 748 is resistant to water, weather and freeze-thaw cycles and is able to accommodate mechanical and thermal loads.

Can be used as a polymer-modified bonding slurry for installation of stone and ceramic coverings using vibrat­ed floor system or conventional thick-bed method.

As bonding layer applied to mineral, cementitious bedding mortars/adhesives and to mineral, cementitious substrates.

As bonding layer for mineral and cementitious bonded screeds.

As bonding layer in conjunction with Sopro DM 610 drainage mortar, Sopro DMX 619 drainage mortar eXtra or suitable mineral, cementitious screeds with single-size aggregate by others.

For application in conjunction with Sopro TVM 858 thick-bed mortar with trass.

Also for tiles with low water absorption (fully vitrified stoneware), stoneware, clinker floor tiles, mosaic, split tiles and split tile fittings, cast stone and Discoloration-resistant natural stone, e.g. limestone tiles, granite, quartzite, slate etc
