Manually-aged structure of granitic plaster painted wall space of historical building exterior wall

Abstract

The invention provides a manually-aged structure of a granitic plaster painted wall space of a historical building exterior wall. In the manually-aged structure of the granitic plaster painted wall space of the historical building exterior wall after local repair and vacancy filling, through a colouring agent coating covering the surface of a mortar bonding layer between the granitic plaster painted wall spaces after local repair and vacancy filling, the colouring agent coating is formed by mixing mineral color powder and an inorganic siloxane solution, and is formed by mixing an acrylic polyurethane solution and an inorganic siloxane solution. A transition zone is arranged between the mortar bonding part of the granitic plaster painted wall space after local repair and vacancy filling andthe mortar bonding part part without repair. The transition belt is coated with the colouring agent coating for transition. The color of the colouring agent coating for transition is a transition color between the target repair color of the repaired part and the original color of the mortar bonding part part without repair. The structure can achieve the effect that the mortar bonding layer of thegranitic plaster painted wall space of the historical building exterior wall is repaired to be the same as the original.

Description

technical field [0001] The invention relates to an old-fashioned structure for the wall surface of the historical building exterior wall painted with water-brushed stone. Background technique [0002] The exterior walls of historic buildings have experienced natural erosion and man-made damage for nearly a hundred years, and many diseases can no longer be restored to their original state through simple repairs. [0003] For the sake of the unity and appreciation of the appearance of historical buildings, the principle of repairing the old as the old and repairing the old as the old is still advocated. The repair is as old as before, and the ideal repair is to use the materials retained on the original exterior wall or the secondary use of some materials removed by itself. When there is no remaining material or part of the removed material cannot be reused, it is necessary to find similar alternative materials for repair. However, under such circumstances, the restored buil...
