How to prevent irregular cracks in the wall after decoration?

If you want to keep the wall from small cracks after the house is renovated, it is best not to let the windows open often, because the wind will blow the walls dry, and then it will be easy to crack.

It is necessary to ensure the details of the decoration, use high-quality materials for decoration, and choose qualified products, which can avoid irregular cracks in the wall.

Choose high-quality materials, and try to choose high-quality wallcovering and white latex, so that the crack resistance will be better, and pay attention to the details.

1. The cracking of the putty layer will cause cracking on the surface of the wall.

Wall scraping putty can make the wall look smoother and more delicate, and the flatness is much higher than that of the cement wall, so that the wall painting effect is better, and it can also save paint. However, if the putty layer cracks, it is easy to cause cracking on the surface. Therefore, it is necessary to avoid cracking the putty layer during construction.

Treatment: If the crack has penetrated deep into the putty layer, you can first use a sharp tool to expand the crack to a cone size, fill in the caulking plaster and polish and level, paste the mesh cloth or kraft paper and then use putty for leveling, and finally paint or paste wallpaper according to the normal process.

2. Cracking of the plastering layer can be avoided by abnormal cracking.

The cracks of the wall plastering layer are divided into two kinds: normal cracking and abnormal cracking, normal cracking mainly refers to the cracks in the plastering layer caused by the shrinkage of cement mortar, and the non-normal cracking is mainly caused by improper materials or construction technology. Normal cracking is difficult to avoid, but abnormal cracking can be avoided.

Treatment method: If there is a large area of hollowing in the plastering layer, the original plastering layer should be knocked out, the plastering layer of cement mortar should be redone, and then painted according to the normal process after leveling. However, the cost will be relatively higher after this treatment.

If there is only a small area of cracking, there is no sand, hollowing, or falling off, you can paste a good cloth all over the wall, and then paint it according to the normal process.

You can use putty to refill the gap, and then apply paint again, if it is only a small gap, you can directly cover it with paint.

Apply the interface agent. After shoveling the wall skin, clean the base layer to ensure that it is free of dust and stains, and then apply the interface agent. This is conducive to better adhesion between the interface agent and the wall.

After brushing the wall paint once can be covered.

1. Pressure grouting method: the air compressor will pour the adhesive into the cracks of the brick wall and re-bond the cracked walls together.

2. External force repair method: open the original gap, repair it with elastic putty, or use a good cloth to fix it.

In most cases, cracking in the wall is caused by the evaporation of moisture in it. Moisture may continue to evaporate, so it may continue to crack even if it is repaired. In addition, if you only repaint a small area, there will be a color difference between the new paint and the old paint.

With wallpaper, the fastest and most effective.

This was supposed to be used when laying the base, and the seam king would not be,

There are small cracks on the newly renovated wall: there are many cracks in the gray layer of the original wall, and the trouser shouts that the painter has not done the wall treatment on the top of it, and the putty will still crack behind it.

Whether it's a colored wall or a large white wall, painting the wall is a complex and lengthy process, and every link cannot be omitted.

Wall painting procedure: general wall painting process: shoveling wall skin - brushing interface agent - brushing plaster - scraping putty twice - wall polishing - primer - topcoat twice.

Shovel wall skin: Shovel wall skin must be repeatedly inspected to ensure the quality of the basement wall, and there must be no excessive hollowing, cracks, irregularities, no matter how good, it is easy to crack.

Brush interface agent: The brush interface agent is mainly used to remove the floating dust on the wall, compact the wall, and enhance the adsorption force of the base layer.

Plaster: The main function of plaster is to adjust the flatness of the wall, make up for defects, repair cracks, and straighten the yin and yang corners of the wall.

Scrape putty twice: Inject the warning to wait until the plaster is dry before starting construction. In general, it is necessary to scrape at least twice, and each time it is not too thick, otherwise it is easy to crack.

What should I do if there are small cracks in the wall of a newly renovated house? Scraping putty is mainly because the wall surface looks smoother and plays a fine and flat role.

Grinding the wall: Grinding the wall is mainly to make up for some small silver digging defects on the wall, usually using sandpaper to polish by hand.

Primer: This is also a step that cannot be ignored. It has the functions of anti-corrosion, yellowing resistance, alkali resistance, etc., and can improve the adhesion of the topcoat and the fullness of the sharp core.

Painting twice: Painting is the last process of painting the wall, and it is also the process that most intuitively reflects the quality, usually brushing twice. We have to find good craftsmen and high-quality finishes.

If you have cracks in the walls of your home, check them quickly. Are you all in place?

After living in a new home for nearly a year, there may be times when you look up and find subtle cracks on the wall, and the mood may not be very good at this time. However, for the existence of such cracks, different methods should be adopted according to the causes of their occurrence.

If it is only the paint layer cracking, it may be because the topcoat is very thin during the decoration and the climate at home is relatively dry, so there is cracking. In this case, you can use fine sandpaper to sand the cracks so that the entire wall is flattened, choose the same wall paint and repaint.

If the crack has penetrated into the putty layer, first use a sharp tool to expand the crack to the size of a screwdriver, then the crack is to be replenished, fill the empty hole, polish the surface, smooth it with kraft paper, then smooth it with putty, and then apply the primer and topcoat according to the normal procedure.

If there is a large area of empty plaster on the plastering layer, the original plastering layer should be knocked off, and the plastering layer of the cement mortar should be reprocessed, then leveled, and then painted according to the normal process. However, this kind of engineering procedure is more complicated, which is tantamount to re-decorating the wall, so the cost of this painting method is relatively high. If only a small area is cracked, and there is no hollowing and peeling, the wall can be flattened and then painted according to the normal process.

For this problem, it is recommended that the owner can wait until the deformation of the entire building remains fixed, and then take relevant measures to deal with it, otherwise it may be modified in a hurry, and cracks will continue to occur, because the symptoms are not cured.

Therefore, even if there is a small crack in the wall, it should be divided into several situations for relevant discussion and then decision, and it cannot be repaired blindly.
