How to paint the wall after soaking in water? Are there any precautions?

First of all, the first question:

The wall is wet, because the original wall is wetted, and it will be more labor-saving when the wall is shoveled;

Remove the part of the original wall that has been flooded, if there is no uneven place that needs to be hung putty, you can not shovel off the putty layer, otherwise you must shovel off the putty layer together;

When the wall is dry, scrape the putty.

Do it two to three times depending on the condition of the original wall, and each time you have to wait until it is completely dry before doing the next time), no need to make putty to omit this step; <>

sandpaper sanding and smoothing;

Brush the primer and topcoat (or roller brush) in turn, the primer twice, the topcoat three times, and wait until it is completely dry before doing the next time;

For the cracks on the wall, it is necessary to do anti-crack treatment. That is, before scraping the putty, use 108 glue at the crack to glue a "really good" cloth that is at least 20 cm wide on both sides of the crack, and then scrape the putty <> after drying

Secondly, the second question:

1. Pay attention to the weather conditions before painting construction and avoid working before the rain and snow come. The old wall must be completely removed from oil, mildew, floating ash and loose coating, and the hole leakage should be repaired in time, and polished with coarse sandpaper.

Second, when painting, you should master the principle of top-down, one-stroke and vertical brush, and you can also brush horizontally from left to right, and do not miss the pen. in the brush lime slurry.

The lime slurry should be constantly stirred during the process, otherwise the lime slurry will precipitate and there will be different stripes on the wall after brushing.

3. Paint and decorate the newly brushed paper stash wall until the outer layer of lime is completely dry, otherwise it will cause spots on the wall and affect the beautification effect. If the lime wall has been painted for less than half a year, add acidic colored wall powder, if green, sky blue and other colors, it is easy to produce neutralization and overcoloring, so you need to pay attention.

The condition of the wall before painting is to apply latex paint.

One of the important foundations, it directly affects the adhesion, decoration and longevity of coatings.

First of all, the humidity of the wall should not be too large. Generally, it is required that the humidity of the wall of latex paint construction should be less than 10% (some paint manufacturers require it to be less than 6%). If the humidity is too high, on the one hand, the moisture in the pores of the wall will block the penetration of the primer and affect the adhesion of the paint film; The continuous evaporation of water will cause the paint film to blister and fall off.

On the other hand, the alkalinity of the new wall is generally large, especially the lime plaster wall, when the moisture in the wall evaporates outward, the alkali of the wall will be brought to the surface, and the concentrated alkali cream after the water evaporates will gather on the surface of the wall, which will cause great damage to the color and luster of the paint film.

It is necessary to pay attention to scrape off all the parts that have been soaked to the skin on the outside, then dry them, blow them with a hair dryer, and then paint them, first apply a thin layer, and then deepen them.

The first point should be painted, so that you can, the second point is that you should pay attention to clean all the damp places, and the third point should be noted, that is, if you apply the powder again, it must be very classic.

When the wall after soaking in water is to be painted, the wall should be dipped in water, then the blistered wall skin should be removed, and the primer and topcoat should be brushed in turn after the wall is dry, and finally the cracks should also be treated.

The viscosity of the wall stucco material after being blistered will be reduced, if the wall decoration material is directly constructed on the surface of the cement mortar, it is likely to appear hollow, falling off, cracking and other phenomena in the later stage, and the soaked cement sand must be all removed until the wall base.

There are many reasons for wall cracking, such as wall cracking caused by the settlement of the foundation, or cracking caused by uneven shrinkage of wall mortar between the old and new walls, and as you said, after immersion, the wall putty screed.

Bulging, cracking, and falling off. When water seepage occurs in the house, it is even more overwhelming, so you need to do some related treatment. Water seeping from the exterior wall to the interior wall is also a common occurrence in our lives.

So, what should you do if the exterior wall seeps into the interior wall? What is the cause of water seeping from the exterior wall to the interior wall?

The first thing we need to do is to find the existing water seepage points on the wall and the cracks in the external wall, and chisel along the cracks to remove the external wall plastering layer and parapet at the interface between the masonry and the structural beam.

Cracked plastering layer and large area of cracks on the exterior wall, before chiseling off the application of a hand-held cutting machine to cut the plastering layer, if the wall cement base cracks, then the surface is shoveled off to expose the cement base surface, the use of waterproof cloth paste to cover the previous cracks, and so on, according to the normal base construction! If there is a large crack in the cement base, this situation is due to the uneven decline of the wall base and needs to be dealt with by professionals!

<> wall cracking is mainly related to the wall and soaking water has little to do with it, if the base treatment is better, the problem is not big, if the treatment is not good, it will be delamination in the later stage. That is, peeling, falling off piece by piece. The nature of the subsidence cracking of the exterior wall surface and the inlet cracks, the settlement cracks, the construction quality factors, the improper use of the fracture, the maintenance is not timely, such as cracking.

Regardless of the cause of the crack, it should be rigorously evaluated, carefully analyzed, and the crack should be found"pathogens, eliminating hidden dangers.

What to do if the wall seeps, the first step is trachoma.

The wall seepage caused by the water seepage, we need to find the existing water seepage points and external wall cracks on the wall, cut the plastering layer with a hand-held cutting machine, and then chisel the plastering layer at the interface between the masonry and the structural beam along the cracks, and clean up the base layer after chiseling off the plastering layer.

At this time, the walls should be completely dried before they can be painted again, otherwise they will be smudged. Completely dry the walls, then scrape off the upturned skin, sand, and paint.

After soaking in water, the strength needs to be dried as a whole, waterproof, and then used putty to find a flat, and then painted.

If it is a water-soaked wall, then the putty underneath has also been soaked. Therefore, if it is to be repaired, the wall should be completely removed, shoveled to the end, and then the putty should be scraped again, and then painted.

If you don't understand the condition of the car and want to buy a second-hand car, you must find a professional inspector, don't look at it yourself, including half-understood half-hangers, although the professional master of the soaking car can detect it in a few minutes.

There is some sediment left in <> places, which are not easy to clean, so it is important to look at the details. For example, if there is mud and sand at the junction between the floor and the door, you should be alert.

In addition, the trunk is also a key part, if there are water traces at the bottom of the spare tire or the current scraping of the wall, there must be measures, otherwise the wall decoration will definitely be moldy and peeling back to alkali.

There are cabinets made of carpentry or modeling or something that have also been soaked, and they must be dismantled and redone, otherwise there will be big problems after a long time. The solidification time is 5-8 hours, at the normal indoor temperature of about 20 degrees, the solidification time should be longer at low temperature, and the solidification time should be shorter at high temperature. The cement mortar generally begins to set in about 45 minutes, and then continues to solidify, no more than 10 maintenance.

I heard you feel that it should only progress to the bricklayer process at present, and it should take about a month for the painters to enter the site, and it will take at least two months for the entire renovation project to be completed. If it's custom furniture, then don't worry, if it's on-site furniture, it's more professional. Disassemble the door lining.

Tear off the dustproof film in the door lining plate to see if the lifter track is rusty, generally this place is not easy to find, and no one will disassemble it. First of all, we have to talk about the appearance, the appearance of the general soaking car will be carefully cleaned by the black-hearted merchants, so we can hardly see anything, but a closer look you can find that most of the soaking car will have yellowing traces in his headlights, and sometimes query 4S maintenance records and accident records. Because most of the cars are blistered, they are often insured and then towed to a 4S shop for repair.

So, that's the most straightforward. If the screws and slides are soaked in water, they will definitely rust, and the seat sponge will definitely have traces of soaking and swelling or hardness! I don't rule out the possibility of a full seat change, after all, it's not much.

If we find that the wall of our home is soaked, do not do anything to treat the wall at this time. We open the windows to allow natural ventilation, which accelerates the evaporation of moisture from the surface of the wall as well as from within. Until all the moisture is dry.

The easiest way to judge is that the surface of the wall is dry, without any moisture and patches, then it means that the wall has seen through. After that, the next step is carried out.

If our walls are plastered, then no special treatment is required. If the wall was originally scraped with putty, then we need to treat the original putty. Whether it is ordinary putty or water-resistant putty, after being blistered, I personally recommend that everyone remove the putty layer to expose the plastered wall inside.

This is one of the most important steps that prevents the walls from experiencing alkali treatment. The most common method is to brush a layer of oxalic acid on the surface of the wall to neutralize the alkaline material inside the wall. Avoid alkali re-alkali re-alkali caused by water immersion in the future.

You only need to shovel off the soaked wall skin and you can repaint, but you must pay attention to make a layer of waterproofing before painting, otherwise it will be like this next time.

For such a wall treatment, we have to go in several steps:

The first step is to check the water leak again, find out the cause, and completely solve the water leakage problem.

The second step is to dry the wall. Drying the walls is mainly solved by time, and at the same time fully open the windows for ventilation. Pay attention to rainy days, and close doors and windows when returning to the south.

If it is a new wall, the drying time will be longer, because it will have to wait for the water in the wall to evaporate, and if it is a water leak, the wall will be damp

1. The wall is wet, because the original wall is wetted, and it will be more labor-saving when the wall is shoveled;

2. Remove the part of the original wall that has been soaked in water, if there is no uneven place that needs to be scraped putty, you can not shovel off the putty layer, otherwise you must shovel off the putty layer together;

3. After the wall is dry, scrape the putty (do it two or three times depending on the condition of the original wall, and wait until it is completely dry each time before doing the next time), no need to make up the putty and omit this step;

4. Sandpaper grinding and smoothing;

5. Brush the primer and topcoat (or roller brush) in turn, the primer is used twice, the topcoat is repeated three times, and each time it is completely dry before doing the next time;

6. For the cracks on the wall, it is necessary to do anti-crack treatment.

That is, before scraping the putty, use 108 glue at the crack to glue a "really good" cloth that is at least 20 cm wide on both sides of the crack, and then scrape the putty <> after drying
