Construction method for repairing old brick wall

Abstract

The invention discloses a construction method for repairing an old brick wall. The construction method includes the following steps that the brick wall is cleaned; removing, digging and mending by replacing damaged parts are conducted on bricks of the wall space of the brick wall, wherein the bricks are locally flaked and severely defective; the polished and cleaned wall space is washed; parts which are removed, dug and excavated are filled with bricks; pointing is conducted again on parts of the brick wall space through a preparation method of original pointing materials, wherein the original pointing materials are weathered or damaged or bulged and dropped on the parts; a process for local repairing and painting by utilizing permeation color paste through site configuration is adopted for parts of the washed brick wall space to achieve the effect that the parts are basically consistent with the whole wall space in color, wherein the parts are large in color difference; the processed wall space is wholly painted with a brick wall permeation protective agent; color alternation and antiquating are conducted on the whole wall space. The construction method is convenient and easy to implement and low in construction cost.

Description

technical field [0001] The invention relates to a construction method for repairing walls, in particular to a construction method for repairing old brick walls. Background technique [0002] In the past, there were many houses with red brick masonry structure in our country, among which single-storey factory buildings also accounted for a certain proportion. With economic development, many red brick masonry houses have been demolished. However, some single-storey factory buildings have a relatively stable structure and are still useful in a short period of time, but some parts of the red brick exterior wall are alkalized, weathered, and seriously stained, and the surface texture and color also affect the appearance. This requires a simple fix.
