If you wipe half of the wall after the decoration, and then wipe it again after half a year, will th

Before plastering the wall in the room, the first thing to remove is to remove the wall, and remove the "slurry" that the workers leave until the brick joints are raised when cutting bricksThere was also smallpox.

The cement mortar dripping from the interface of the mold when the top of the ceiling is irrigated with the floor slab.

and nails and wire heads and other foods are cleaned neatly to prevent harm to the work of batch putty. After the wall is "wetted", the adhesion of the cement slurry can be improved, so that the mixed mortar and the wall are more firmly and closely connected, and the quality of the batch putty layer can be improved! And the wall has not been watered, you can directly criticize the putty.

The stucco layer wall hollowing occurs in the middle and late stages.

The peeling condition is inseparable from this, so the wall must be watered when the wall is plastered! Cracking has nothing to do with your early putty and late plastering. Just worry about finishing the putty powder.

After not brushing paint for a long time, the putty powder layer will delamination. Endanger the adhesion of wall paint in the middle and late stages, and even the service life after spraying. Be sure to wipe the whole surface at one time, so that the wall plastering layer is not easy to have uneven dry and humidity, inconsistent water consumption and cracking, which will cause harm to the interior decoration of other raw materials for the wall in the middle and later stages.

Interior decoration wipe half, if it is a batch of putty, the old and new joints will be gaps, the old has been dry, put away the shape, the new to be dry, folded. After the new batch of putty is dry, paste anti-cracking five defenses at the butt.

cloth, in the scraping putty.

If it is an interior decoration, half of it is a small white (putty powder) that is not easy to crackThe permeability of the wall watering, especially the original wall of the putty, also needs to be watered, and the putty will increase the initial setting of the mortar after the wall is watered, so that the cement mortar will gradually converge and reduce the possibility of cracking the stucco layer.

Chisel off some of the stucco layer at the junction (chisel into a steep slope type), and make the handover of the batch putty work longer, so that the new cement mortar and the cement mortar on the old wall are fused more densely, resulting in that kind of "impeccable" practical effect, and then reduce the cracking of the socket! Whether the joint will crack depends on the specific situation, but there is no doubt that there are significant tight joint marks at the joint, which is inevitable because the wall is not a timely batch of putty workOn the contrary, the spacing is more than half a year and gradually progresses in sections, so it is inevitable that there will be problems at the seams.

It is easy to crack, because in this case, the dryness and humidity of the putty on the old and new walls will be different, and it will probably crack.

The position of the old and new wall oblique street is generally not cracked, even if it is cracked, this phenomenon can be avoided, and it can be lapped with steel wire mesh at the junction of the old and new walls, so that there will be no cracking between the balloon walls, which does not affect the aesthetics, and is also particularly practical.

It will crack, and if there is no way to ventilate it well, this situation will definitely crack.

When making wall latex paint, it is necessary to wait for the new batch of putty to dry the wall before it can be carried out, and the intersection of the new and old walls should be pasted with a wide grid to carry out anti-cracking solutions, how to minimize the risk of cracking at the intersection in the middle and later stages. Not only is the area where the new and old stucco wall layers are docked to be pasted with a grid to carry out anti-cracking solutions, but these water and electricity pipes are opened in the slots in the wall. Construction steps The joints of the old and new walls and the concrete layer of the old walls are removed.

When building a new wall, the embedded parts are pressed to connect the new and old walls with each other; When the concrete is brushed on the wall, the joints of the new and old walls are hung with fiberglass mesh; (There are some ways to hang iron mesh, as much as possible with chemical fibers, iron is very easy to rust). Long-term drying: In order to prevent unbalanced dryness, the new wall can quickly be as dry as the old wall, and it is recommended that the maintenance period after the new wall is built, do not rush to scrape the gypsum and putty, let the bare wall dry for as long as possible, and let the water volatilize as much as possible. Unified materials It is proposed that in the case of building a new wall, we must pay attention to one point in the case of thin and thick, that is, the new wall of the wall must be concave 1-2 cm than the old wall after painting, and then put a layer of gypsum board on the upper edge after drying, <>

Leave 3mm up and down to scrape gypsum or putty and its mesh cloth or kraft paper bag, pay attention to the surface layer is all unified raw materials, gypsum or putty, the difference between heat and cold contraction is very small, and the harm will be relatively small, which can have the effect of slowing down or avoiding cracking. If it is necessary to paint it, it should be covered as much as possible to avoid dry cracks at the junction of the old and new walls. Unified materials It is proposed that in the case of building a new wall, we must pay attention to one point in the case of thin and thick, that is, the new wall of the wall must be concave 1-2 cm than the old wall after painting, and then put a layer of gypsum board on the upper edge after drying, and then leave 3mm up and down to scrape gypsum or putty and its grid cloth or kraft paper bag, <>

Note that the surface layer can be made of uniform raw materials, gypsum or putty, and the difference between heat and cold contraction is very small, and the harm will be relatively small, which can have the effect of slowing down or avoiding cracking. First, the old wall is chiseled into arbitrary burrs, and the butt between the old and new degrees is scraped flat, but the shrinkage of the concrete is likely to cause gaps, and in the case of the final decoration of the wall, the mesh cloth is used to paste it, which is not easy to affect the overall wall. Before batch putty, the wall plastering at the junction between the old wall and the new wall is removed 150 width, and then the steel wire mesh is pasted.

Then carry out the batch of putty that plugs the leaking wall. It is best to pre-bury a 20-wide dividing joint at the junction of the old and new walls, and then replace the separating joint with a closed type of bonded mortar 15 days after painting.

This may happen and needs to be treated to avoid it, and the location of the articulation may need to be watered.

In the process of new and old decoration, the part of the wall connection is likely to crack, so the connection is very important at this time, and you should look at the original decoration condition before deciding.

Depending on the situation, the material used and the specific temperature will affect whether the cracking will occur.

No, but there are a few things to keep in mind when reapplying:

1. Make sure that the paint used is the same as the previous paint type.

2. The surface of the front paint should be kept clean, no oil stains, no impurities 3, and then the paint is the surface of the front paint to be sandblasted, to achieve grade 4, color selection, not because of the selection of paint lighter than the previous paint, otherwise it will not cover the color of the front paint, affecting the appearance.

Exterior wall painting is generally used outdoor acrylic or fluorocarbon paint, if you can not detect the specific type of paint of the front paint, you can consult Hangzhou Yasheng paint, exterior wall paint recommended Zhejiang Bridge paint, Hangzhou Zhuoyue paint.
