Method for tint rehabilitation of rocks

摘要

A method is disclosed for rehabilitating an exposed cut surface of a rock formation after rock cutting has occurred so that the fresh cut surface becomes weathered and natural within several weeks to facilitate restoration back to its original shade as a part of the natural scenery. Weathering occurs by applying a solution containing FeCl2 or MnSO4 to the surface of the rocks to be colored. These rocks are limestone, dolostone, phosphorite and concrete. A method for preparing a weathering solution is also disclosed.
