How should wall joints be treated throughout the home improvement process

<> includes wall coverings. How to decorate the wall without cracking is a problem that decoration owners are more concerned about. The rough wall of the new house is rare, basically it is four white to the ground, and the putty on the wall of the developer is scraped, which plays the role of acceptance by the relevant departments.

Because it is not fine decoration, the relevant departments do not have higher requirements for wall decoration, so developers use ordinary putty to scrape the wall. Also known as stucco plaster, it is mainly used for wall caulking or smoothing mesh cloth. The initial setting effect of gypsum powder is particularly good, the amount should be small when stirring, so as to avoid drying up before it is used up, and the gypsum powder ** is also very high, reducing unnecessary waste.

When the gypsum powder smooths the mesh cloth, the wall is almost dry, and the advantages of the mesh cloth are mainly used to better protect the wall and avoid a series of quality problems after fine decoration. Effectively prevent the wall from cracking.

It's putty. The batch scraping of wall putty is the basis of our wall paint painting, so it must not be ignored in the painting paint. Because the quality of putty scraping determines the quality of our surface coating to a certain extent, and also determines how long the surface coating can be used in the future.

A common topcoat is a latex paint used in the home. The surface coating is applied to the bottom layer of putty by roller coating or spraying, and the paint is the final completion state of the wall in our home, so the good and bad of the paint are finally reflected in this step.

The key item that needs to be paid attention to here is whether our putty has a serious phenomenon of powdering and powdering. If there is serious powdering and powder loss of wall putty, corresponding measures must be taken to deal with it. In addition, whether the putty peels off and hollows, and the overall cracking, like these situations, the putty must be removed in advance, and then the putty is scraped again.

Because before the paint is painted, it is necessary to use fine sandpaper to carefully polish the surface of the putty, and after grinding, it is also necessary to use a hair dryer to blow the dust on the surface to ensure that there is no dust on the surface of the base layer before it is allowed to paint the coating.

It should be smoothed and the seams should be coated with more latex paint so that the seams are not visible.

The wall joints should be covered with some gauze first, and then covered with putty powder on top of the gauze, so that the joints of the wall can be treated.

The wall joints can be treated with beautiful seams, which will be more beautiful after the beautiful seams, and they are also very practical, which can be waterproof and moisture-proof.

The butt joints that often need to be treated in construction are the construction joints in the horizontal position and the post-pouring joints caused by structural design reasons, and the treatment methods of the two butt joints are different.

1. Treat the construction joints in the horizontal position

First, clean up the garbage and dirt in the construction joints, and also need to chisel the old concrete, and at the same time need to use clean water to moisten it. Secondly, the position of the rebar should be adjusted well, and it also needs to be cleaned. Then use cement mortar of the same strength grade to pour at the construction joint in the horizontal position, and the pouring thickness can be kept between 10 mm and 15 mm.

2. Deal with the post-pouring joints caused by structural design

Expanded concrete can be used to pour the construction joint location. If the construction joints between the cast-in-place concrete and the precast beams and columns are treated, then the gaps in the horizontal position should be dry-mixed with some cement mortar, and the construction joints in the vertical position should be poured with some expanded concrete.

1. When carrying out concrete construction, if the construction personnel have improper construction, the surface is prone to cracks, and if there are cracks on the concrete surface, it will cause the use of the building to be affected, so it is recommended that we must try to avoid cracking on the concrete surface when carrying out concrete construction.

2. In order to effectively avoid cracking on the surface of concrete, it is recommended that you must modulate the concrete in strict accordance with the correct proportion, and be sure to mix the concrete evenly.

Is it common for cracks to appear on the wall after the completion of the home improvement paint application? Wall cracks not only greatly reduce the decoration effect of the wall, but also affect the effect of our entire home decoration. Therefore, we need to patch it in time.

There are several main reasons for cracks in the wall:

1.cracks in the insulation layer of the original house, which is the most common factor causing wall cracks after renovation;

2.Improper repair and painting of the wall after slotting, resulting in the shrinkage of the wall and cracks;

3.When plastering, the cement ratio is too high, resulting in cracking;

4.Improper ratio of wall putty or uneven scraping;

5.Latex paint and whose ratio is inappropriate.

In home improvement construction, we can prevent wall cracking from these aspects:

1.Pay attention to the ratio of cement and sand, the optimal ratio is 1:3, improper ratio will affect the toughness and tension of the wall;

2.Find the ratio of putty and latex paint;

3.The circuit transformation should be carried out together with the carpentry foundation as much as possible to prevent shrinkage and sag when repairing after slotting;

4.When cracks appear on the colored wall, try not to take the method of local repair, so as not to form color difference;

5.If there are cracks in the wall insulation board, the cracks can be cracked with a putty knife, filled with gypsum, and the cracks are pasted with bandages and nylon mesh cloth, and then scraped putty or other processes after drying.
