What to do if the wall is damp and the paint is slag, and what to do if the wall is damp and peels o

Lift the wall up, do waterproofing, and then do latex paint, if the base layer of the wall is not treated well, you can do it according to the following method:

1. The wall is wet (wetting the original wall, saving effort when shoveling) 2. Shoveling part of the wall around the place where the original wall has fallen off can be appropriately expanded.

3. After the wall is dry, scrape the putty (depending on the condition of the original wall to do two to three times, each time to wait until it is completely dry before doing the next time), 4, sandpaper grinding and smoothing, 5, brush the primer and the topcoat (or roller brush) in turn, the primer twice, the topcoat three times, each time to wait until 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.

If the wall is damp, it is normal for the local climate to be humid or the back of the damp wall is damp, and the wall is damp due to water seepage from the back.

1. Thoroughly clean the peeled and damp wall with a shovel.

2. Continue to remove the floating ash on the wall to prevent the floating ash from affecting the bonding strength.

3. Evenly brush the separator with a brush and apply it 2-3 times, with an interval of about 3 hours between each time.

4. After the isolator is dried, the putty can be scraped in batches, and the batch scraping time is not less than 24 hours each time.

5. After the putty is dried, carefully polish it with No. 180 sandpaper.

6. Clean the surface dust and paint latex paint 2-3 times, with an interval of about 6 hours between each time.

Tools: Wall Repair Kit.

1. First remove the damaged and damp wall to the cement layer, clean up the dirt and dust on the construction surface, and keep it clean and dry.

2. Take out the wall repair kit purchased from the Internet**.

3. Brush the cement surface 2 3 times with a separator, with an interval of about 3 hours between each time.

4. After drying the next day, use water-resistant putty paste to scrape the construction place, and after 4 6 hours of drying, polish the wall with sandpaper.

5. After the putty paste dries the next day, clean the surface dust and paint latex paint 2 3 times, with an interval of about 3 hours between each time.

The reasons why the walls are wet and peeling are as follows:

1. Water seepage on the exterior wall: cracks that occur when the insulation layer of the exterior wall is not done, or the waterproof layer of the exterior wall of the building is damaged, resulting in dampness and peeling of the wall.

2. The waterproof of the bathroom is not good: the waterproof height of the bathroom is not done well, which causes the wall to be damp and peeling.

3. The putty powder and paint used in the decoration do not meet the environmental protection standards, or the putty powder is painted before it dries, resulting in dampness and peeling of the wall.

First of all, the wall is wet, and then the part of the wall around the place where the original wall has fallen off is removed, and after the wall is dry, scrape putty. After that, sandpaper is sanded and smoothed. Brush the primer and topcoat in turn, the primer is used twice and the topcoat is applied three times. Finally, the cracks on the wall should be treated with anti-cracking.

Sometimes the decoration is not long after the completion of the wall, and the wall appears to be a block of putty floating and falling, the main reasons are poor construction technology, putty, poor paint adhesion and shrinkage performance. The quality of the construction process requires a professional construction team and experienced construction personnel, which reminds us that we must be cautious when looking for a decoration company and do not be greedy for cheap. The solution to this problem requires the reinforcement of the base layer, the removal of the wall surface in the peeling area, the complete removal of debris from the wall, and the repainting of putty and painting.

There is a difference in the lacquer applied to the interior and exterior walls. The worker's craftsmanship, the layman is completely indistinguishable, first of all, the finch skin to choose high-quality products, especially high-quality putty, should choose well-known enterprises water-resistant putty. These putties have high whiteness, good water resistance, high bonding strength, no peeling, no chalking, and no falling off after use, which can solve the trouble of wall skin peeling; Before painting latex paint, you need to scrape the putty shed at least two or three times; Add 108 glue with gypsum powder to increase the viscosity.

This answer is applicable to the slag disposal of the wall in most of the chain bureaus.

How to solve the slag of the new house wall: 1. Shovel the original latex paint and batch ash to dig the omen, and shovel to the stage of the blank layer, so that it is better to plaster in the later stage.

2. Re-plastering, re-painting with cement mortar, and after drying, you can brush a layer of wall treasure, the function of this layer is to resist jujube powder alkali bench rock, moisture-proof, and increase viscosity.

3. To brush putty powder, you can use exterior wall putty as a base first, because exterior wall putty is more waterproof and sunproof. Therefore, it is more durable to use exterior wall putty as a base.

4. After brushing putty powder, you can polish it after drying, this depends on your own requirements, generally more than two times, polish it is completed, and brush latex paint.

What to do if the wall is damp and peeling: 1. Reinforcement of the base layer: If the wall is peeling and peeling on a large scale, then first see if there is a problem with the bottom layer of the wall.

During construction, it is necessary to re-reinforce the substrate with Gordon Refresh Wall Reinforcing Agent, and then do a series of steps such as plaster leveling, pasting mesh cloth, brushing primer and painting. 2. Brush the topcoat to cover the cracks: After the survey, if there is no chalking or peeling off on the wall, you can directly paint the topcoat to cover the place where the peeling is not very serious, which is almost the best one.

3. Demolish the old wall and install a new wall: If the wall peeling is very serious and affects the aesthetics, at this time, when the simple repair is useless, it is necessary to remove all the decoration of the old wall, and then carry out a new decoration, first of all, to remove the cement layer, and then follow the basic steps of brushing the wall for construction. This answer is applicable to most cases where the wall is damp.

The wall is damp and peeled off after repairing, because the wall is still in a state of moisture, the wall should be waterproofed before the wall skin is repaired, and the damp wall should be removed and then painted, and the waterproof coating is painted on the base layer, that is, the cement layer. Relevant popular science knowledge: 1. For a wide range of wall peeling, the wall should be reinforced during construction, and the form of gypsum or iron mesh cloth should be reinforced, and the reinforcement work can be carried out in accordance with the normal decoration steps after the reinforcement work is completed.

2. In the process of painting, we should pay attention to the primer and the stucco of the topcoat, the primer is generally painted twice, the topcoat is generally painted three times, and each time the painting must wait until it is completely dry, and then the second time of painting. 3. When the wall is damp, we must first know the cause of the dampness, because the weather should open the window frequently and ventilate, because the water pipe should be repaired in time, and the wall should be repaired in time in the process of repairing the paint. If the wall is touched up in a wet state, a large number of cracks will occur after the wall is dry, and there will be bubbling and falling off at the connection of the paint repair.

4. When touching up the paint, the latex paint on the surface must be cleaned up, and then brush the latex paint for the second time, the latex paint has a certain waterproofness, and the old latex paint is not removed, and the oil stains and stains on the surface of the latex paint cannot be glued together.
