The constructional finishing material includes 70-85wt.%% of the aggregate coated with the pearl pigment and 15-30wt.%% of adhesive binder. The adhesive binder includes : 35-40wt.%% of water, 0.5-1wt.%% of dispersant, 50-60wt.%% of acryl based binder, 2-5wt.%% of acryl based thickener and 0.5-1wt.%% of pH regulator. The adhesive binder is mostly acryl based binder and especially, urethane or epoxy resin.
