Description
Technical Field
A method for repairing the cracking of latex paint is used for repairing the hollowing and cracking position of a wall surface, and belongs to the technical field of building construction.
Background
The building wall is generally divided into an outer wall and an inner wall, the base layer of the building wall is a concrete wall, and the inner wall and the outer wall of the building wall can be decorated in order to improve the aesthetic property of the building wall; the latex paint coating is the most common construction method, the process is complicated, and the latex paint is easy to hollowly crack after being coated, particularly the latex paint is close to the upper area of a baseboard of a toilet or a kitchen, the hollowly crack can be caused after being used for about 2 years, and the attractiveness is seriously influenced.
For the inner wall body with the hollowing crack, the traditional repairing method mainly comprises six steps:
step one, shoveling off all the hollowing cracking areas by a shovel blade;
step two, scraping and coating coarse putty to fill pits;
step three, polishing the dried coarse putty by using coarse sand paper (100-200 meshes);
step four, coating fine particles for leveling;
step five, the fine particles are dried and then polished by fine sand paper (200 meshes to 300 meshes);
and step six, coating the latex paint with the corresponding color.
Although the method can be used for repairing cracked latex paint, the steps are complicated, the time consumption is long, the environment pollution caused by polishing putty is serious, meanwhile, the method is high in specificity and needs a professional matched tool, in addition, when the hollow drum part meets a wall surface crack with the width of 2mm-5mm and the skinning height of 1mm-3mm, if the latex paint is directly coated by roller, the cracking area of the bag part is increased due to high adhesiveness and strong cohesive force of the latex paint, and even the phenomenon that the hollow drum completely falls off occurs.

(2) after the paint film in the step (1) is dried for 5-10min, brushing the cracked and peripheral area of 3cm by using diluted latex paint once by using a shading brush, wherein the mass ratio of the latex paint to water is 1: 4-6;
(3) after the paint film in the step (2) is dried for 15-20min, brushing the cracked and peripheral 2cm range area with diluted latex paint once by using a row brush, wherein the mass ratio of the latex paint to water is 1: 1;
(4) and (4) after the paint film in the step (3) is dried for 30-40min, brushing the cracked and surrounding area of 1cm once with diluted latex paint by using a row brush, wherein the mass ratio of the latex paint to water is (8-12) to 1.
Preferably, in the step (1), the brushing process is started from the upper part of the crack, the shading brush is inclined upwards and is brushed with the wall at an oblique angle of 30 degrees, and the dry film thickness of the brushing is less than 10 μm.
Preferably, in the step (2), the brushing process is started from the upper part of the crack, the shading brush is inclined upwards and is brushed at an oblique angle of 45 degrees with the wall, and the dry film thickness of the brushing is less than 15 μm.
Preferably, in the step (3), the brush is arranged vertically to the wall at a 90-degree right angle during brushing, and the thickness of the coated dry film is less than 30 μm.
Preferably, in the step (4), the brush is arranged vertically to the wall at a 90-degree right angle during brushing, and the thickness of the coated dry film is less than 50 μm.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:
1. compared with the traditional process, the process is reduced from six steps to four steps, the process time consumption is reduced from 8.33 hours to 1.5 hours, the process steps are simplified, the repairing time is greatly shortened, tools and materials such as a scraper, sand paper, putty powder and the like are not needed in the repairing process, the indoor environment cannot be polluted due to the polishing of the putty powder, and even non-professional personnel can carry out repairing.
2. The method for repairing the latex paint is simple to operate, only corresponding latex paint is required to be coated, and the latex paint is coated in batches, so that the adhesion of the latex paint after repairing is improved, the latex paint is not easy to fall off, and the structural stability after repairing is improved.
3. When the emulsion paint is coated in batches, the coating range of the cracking area is gradually reduced (from cracking and the periphery of the cracking area is gradually reduced to 1cm from 3 cm), so that the cracking position is effectively repaired, the stress strength of the cracking position is favorably improved, and the color difference range after repair is reduced, so that the repaired wall body is more attractive.
