cement and aggregate screed applicable at thicknesses ranging from 4.5 to 6 mm (3/16 to 1/4 in). It is designed to provide good resistance to abrasion, impact, chemical attack and other physical aggression, including thermal shock, when applied at 6 mm (1/4 in). Selected aggregate can be broadcast onto the wet screed to produce a surface texture
