To provide a mortar-based outer wall finishing material capable of being applied to houses up to three-story houses by a dry construction method throughout the year.
The mortar of the outer wall material comprises white Portland cement, inorganic lightweight aggregates, inorganic aggregates such as silica sand, an inorganic cement colorant such as a metal oxide, and a chemical additive based on a polycarboxylic acid, a modified lignin sulfonic acid or their mixture and used for concrete. The mortar is mixed with alkali-resistant glass fibers and combined with a vinylon (R) net for reinforcement to give a lightweight aggregate-mixed lightweight color mortar plate having a bulk density of 1.4-1.8, a prescribed size and a prescribed shape and further having the reinforcing vinylon net at an inner position of 7 mm-12 mm from the back surface of the weight aggregate-mixed light weight color mortar plate.
