Product Description

Trass cement-bonded bedding mortar for laying natural stones, pavers, flags and tiles in outdoor areas. Due to grading curve, a highly-water-permeable mortar bed is achieved which has virtually no capillary suction, thereby effectively preventing water damage, such as efflorescence and structural damage caused by frost, on balconies, patios, stairs, landings and other external areas. The covering material is laid wet-on-wet using Sopro HSF 448.
