WARNINGS: Mortar thickness is maximum 20 mm and minimum 5 mm. In the summer period protect the mortar from quick drying with suitable protection and where necessary, moisten the bricks, blocks or substrates before applying. Do not apply to blocks, bricks or substrates that are frozen, thawing or with frost risk in the 24 hours after applying. Using an excessive amount of mixing water determines the reduction of mechanical strength and the increase in hydraulic shrinkage of the hardened mortar.
