Special, rapid-set, cement-bound premixed dry mortar with ternary binder system, special single-sized grading and rapid strength development. For indoor and outdoor laying of tiles and natural stone units, particularly on balconies and patios. Extra reliability thanks to highly pervious, largely efflorescence-free mortar bed, which offers full protection against water-induced damage, e.g. microstructural failure through frost action. Drainage performance may be enhanced by incorporating Sopro DRM 653 drainage mat. Covering material is subsequently laid wet-onwet using Sopro HSF 748 flexible bonding slurry with trass.
