How to remove stains from leaks on the ceiling. How to remove yellow water and rust stains on the ceiling and walls with your own hands How to remove yellow stains on the ceiling after a leak

It is very disappointing when, literally immediately after the repair, the neighbors from above drown you. How from the ceiling, so that it becomes perfectly white again?

The main reason for the appearance of yellow spots after flooding is not completely dried floor slabs. Even if the plaster dries completely, yellowish stains can still remain. In addition, the reinforcement in the floor slabs can begin to rust, which makes the stains even brighter.

Of course, the best way out of this situation is to present an invoice to a neighbor for a damaged repair. However, it often happens that you have to deal with the consequences of the flood yourself. How to remove rust spots and how to remove yellowness?

Removing yellow stains after flooding

The first thing to do if you are flooded is to turn off the electricity in the panel. You don't know how far the water is from the wiring. After that, proceed to the removal of yellowness.

The first method that can be used is the mechanical removal of stains. This option does not require the use of chemicals and is completely safe. You will have to clean off the paint, putty, remove wet plaster with a spatula. All damaged surfaces should be thoroughly cleaned.

After cleaning, you need to wait a bit until the ceiling dries completely. After that, a primer is applied and the ceiling is covered with a finishing putty. All defects on the putty are polished with sandpaper. It remains only to repaint the dried ceiling.

If you plan to whitewash the ceiling, it is best to apply two coats of whitewash after the flood. You can just whiten the yellow spot in two layers, but only if it is small.

Can . You can use whiteness or any other product that contains chlorine. Many even use the duckling toilet product.

In order to remove yellow stains with bleach, you must:

• Clean the surface of damaged finishing materials with a spatula.
• Pour whiteness into a container, prepare sponges.
• With a sponge soaked in bleach, you should carefully wipe off the yellowness, moving from the edges of the stain to its center.
• When the sponge turns red, it needs to be washed or changed.
• When the ceiling dries after processing, you can begin finishing work.

Preparations for removing yellow spots

Instead of bleach, you can use some other means. Which also effectively remove yellowness.

For example, by diluting 250 g of copper sulfate in a liter of water, even rusty streams can be removed. They must work with gloves, wiping the traces of the flood with sponges. Many owners use warm blue vitriol in such cases. To do this, dilute 500 g of vitriol in 5 liters of water and heat the solution to 70 degrees.

If copper sulfate does not work, then 250 g of grated laundry soap, as well as 40 g of drying oil, are added to the solution. The resulting solution wipes the stains.

A more dangerous, but most effective method is the treatment of stains with hydrochloric acid. A 3% solution of hydrochloric acid should be heated to 40 degrees, and then they should be washed with stains.

You can also use a homemade mixture to remove traces of the flood:

• 2 parts of chalk and part of citric acid are mixed.
• A part of pharmacy glycerin and a little water are added to the resulting mixture.
• The mixture is thickly applied to the stains on the ceiling and left for 40 minutes.
• It remains only to rinse the ceiling with warm water and repeat the procedure again if necessary.

Rust control

To get rid of rusty streaks after a flood on the ceiling and walls, copper sulfate is again useful. The product is poisonous, so you need to work in personal protective equipment and with open windows.

Bright red stains can be removed. You will need:

• Copper sulfate 10%.
• Brown laundry soap 72%.
• Bone glue.
• Drying oil.
• Sponges or brush.

You should grate a bar of soap on a grater. And then mix the chips with 250 g of vitriol. 200 g of glue and 50 g of drying oil are also added there.

Before work, you need to carefully clean the drips to the possible depth. Then the prepared mixture is applied with a brush or sponge to the stains.

You can do it easier if rusty streaks appear on the ceiling. To do this, the affected area is treated with vitriol, then primed, puttied, painted over with paint. It is best to use oil paint, which forms a dense film. Rust will not show through this film again. If the ceiling before the flood was painted over with water-based paint, then it can also be used for repairs.

Plastic and stretch ceilings

PVC ceilings are prone to mold. Voids are ideal places for fungus to spread. A temporary measure, if it is necessary to remove yellowness and mold from the stretch ceiling, is a household bleach with chlorine of the Whiteness type. Such products help to quickly clean surfaces, and their fumes inhibit the development of fungi. But completely with the help of bleach on a stretch ceiling, traces of mold and yellowness cannot be completely eliminated. There is only one way out - repairing the ceiling. Otherwise, polymer ceilings are very unpretentious, and you can simply wash them even with a dishwashing sink or washing powder.

Drywall

If the plasterboard ceiling is flooded, then you first need to clean the surface with large sandpaper as deep as possible. Surrounding objects need to be covered, as a lot of dust will fly.

Then, using a spatula, a starting putty of medium viscosity is applied. After it dries, the finishing mixture is applied. When the ceiling is completely dry, it must be sanded. This time, grinding is done with the finest sandpaper.

When the surface becomes perfectly smooth, it needs to be primed. But doubts may arise when it comes to painting. An excellent solution is to paint the entire ceiling so that there are no streaks left. But many owners repaint only the area affected by the flood. At the junctions of the ceiling and walls, brushes should be used so that there are no islands that are not covered with paint.

Stains after painting

Sometimes after the repair it may turn out that the yellowish stains still remain. Most often, the decision is made to paint the surface again. But it doesn't really solve the problem. How to neutralize the error in the work and what are their causes?

If the paint was too thick, then it could lie unevenly. It is necessary to choose a liquid paint that will lay down in a thin and even layer. If the work was carried out too slowly, then the paint could harden before the second layer lay down. So all the joints between the strokes become very noticeable.

If the roller was too fleecy, then the paint layer could lie unevenly. It is necessary to select only high-quality tools for work. Also, the fault of poor painting can be a poor-quality primer.

If the work was carried out in poor lighting, it may turn out that they were performed poorly. The work area must be well lit. You can not apply paint in only one direction.

To correct errors, you can grind all the flaws with fine sandpaper. Sand until the surface is smooth.

You can apply the finishing mixture again, and then repeat the light sanding. It needs to be primed twice for painting. After priming, the ceiling should be painted over twice so that yellowness and rust do not show through.

Prevention

It is also necessary during the overhaul to make sure that the ceiling is well insulated and check how far the pipes go. Be sure to monitor the condition of pipes and sewers, replace them in a timely manner. The simplest solution is a plastic or stretch ceiling that is easy to clean.

Clogging of ventilation should not be allowed, and you should also organize your life in such a way that there are no various incidents.

Living in an apartment is always associated with the risk of flooding by neighbors from above. Of course, not all owners are faced with such problems, but if the apartment is already flooded, then you have to figure out how to eliminate the consequences of this unpleasant factor. The most noticeable part of the problem is the appearance of stains or damage on the ceiling. How to remove stains on the ceiling after flooding an apartment will be discussed in this article.

Whitewashed concrete floor

An ordinary concrete floor slab very often acts as the main ceiling in an apartment. The finishing material in this case is whitewash. Repairing the ceiling after the flood under such conditions will be quite problematic, but still possible.

To remove yellow spots on the ceiling after flooding, you can use one of the following methods:

• Mechanical repair of the ceiling;
• Chemical repair;
• Combined method.

The latter option is quite relevant - flooding often leads not only to stains, but also to other damage, so a complex of operations may be required to restore the ceiling finish. Of course, before you remove smudges on the ceiling, you need to consider the available methods used in such cases.

Mechanical repair of the ceiling after flooding

Ceiling restoration after flooding is carried out as follows:

• Before you remove the stains on the ceiling after flooding, you need to assess the extent of the damage. If, as a result of flooding, putty or plaster crumbled, then this coating layer must be removed. The resulting bubbles are broken with a hammer, and all exfoliating elements are removed with a spatula. Spots that have reached entire areas of the coating will also have to be completely scraped off or cut down. The cleaned ceiling must be left to dry completely.
• The ceiling that has undergone a leak may contain metal elements. Of course, the bare fittings located next to the rust must be restored and necessarily separated from the ceiling finish. It is recommended to carefully tap the concrete with the sharp edge of a hammer to find delaminations.

• The metal elements found as a result of the check must be cleaned with a steel brush or sandpaper to remove rust from the ceiling. In the future, the metal is covered with two layers of paint, and it is desirable to choose compounds that can neutralize rust. Protection of the floor reinforcement will prevent further staining of the ceiling, which can occur due to moisture remaining in the thickness of the concrete.
• When the paint hardens, the damaged areas of the ceiling must be treated with a primer. Different compositions are suitable for this - for example, an aqueous latex solution in a ratio of 1: 3. In the absence of visible metal parts, the repair technology does not change - the ceiling is still primed, since in the future it will be covered with a fine finish, for which the structure must have good adhesion.

• To eliminate potholes and failures of the ceiling structure, you can use moisture-resistant leveling compounds made on the basis of cement. A good option for such a composition would be tile adhesive. In any case, the composition is prepared for work in accordance with the instructions attached to it and applied in layers to the ceiling. After applying each layer, you need to give it setting time, but you should not wait for the final solidification.
• After preparing the ceiling, it remains only to carry out the final work, covering the ceiling with a fine finish. As a rule, gypsum putty is used for this. It is applied in several (usually two) layers, leveled and left in this form until dry. In the future, it will be necessary to sand the coating so that it is as even as possible.
• Before you paint over smudges on the ceiling, it will need to be treated with a primer again. Of course, to completely eliminate stains and uniform coverage, the ceiling will have to be covered with several layers of paint, the amount of which directly depends on the saturation of the composition.

As you can conclude, the repair technology is quite complicated, and such a restoration will require a lot of effort and financial costs. But these shortcomings are compensated by the high quality of such repairs.

How to remove stains on the ceiling with a chemical method

If there is high-quality waterproofing of the floor in the apartment from above and if the flooding was eliminated as soon as possible, then it will be easier to solve the problem with damage to the ceiling. The thing is that under these conditions the risk of damage to the finish is not so high. That is why there is a possibility that from the damage there will be only red spots on the ceiling and characteristic stains.

You need to understand that washing the ceiling from stains is not one operation, but a whole range of activities. The problem is that the characteristic yellow spots that appear on the ceiling after flooding are not uniform damage, so it will not work to find a universal solution to this problem. When deciding how to fix a leak on the ceiling, it should be borne in mind that the mechanical repair method is more effective, but with the help of chemistry, you can achieve the right result.

The technology for removing stains on the ceiling by a chemical method consists of the following steps:

1. Before you clean the leaks on the ceiling, you need to remove a layer of paint from the surface of the ceiling. Since the ceiling is already wet, this operation will require minimal effort. It is not worth hoping that the wet paint is not damaged - its structure is guaranteed to be destroyed when exposed to water, and in the future the coating will simply peel off, so it will be much more reliable to completely renew it.
2. The dried ceiling must be degreased in order to remove various oils from the surface that have fallen into the ceiling along with water. For this operation, you can use any suitable composition - for example, a nitro solvent. Degreasing will make it possible to remove contamination on all layers of the structure, and not just on its surface. A clean rag cut is quite suitable as a tool for applying the solvent.
3. Further, the prepared ceiling must be rid of coloring pigments, due to which smudges appear on the ceiling. Any household chemicals intended for cleaning will do. The main condition is that the composition of the substance must contain chlorine. Since chemistry discolors any colors, care must be taken before work that the floor is not damaged due to the product dripping down. The ceiling is cleaned with a sponge. It is not worth keeping a sponge soaked in bleach in one area for too long - as a result, putty may begin to crumble, and the ceiling finish will have to be updated.
4. At some point in the work, the stain will stop losing color. As soon as this happens, you will need to stop the operation and leave the ceiling in a soaked state for about an hour - thanks to this, the chlorine will finish interacting with the stain. This is an important point to consider before whitening the yellow spots on the ceiling.
5. After an hour, the ceiling can be washed further, but this time you need to use ordinary detergents - for example, laundry soap or washing powder. This operation allows you to solve two problems at once - firstly, to remove all ordinary pollution from the ceiling, and secondly, to wash the chlorine remaining on the ceiling.
6. The last stage of work is washing the ceiling with clean water. As a tool, you can use a sponge or a piece of foam rubber. At this stage, it is necessary to completely remove all detergent residues from the ceiling surface.

Of course, the result of cleaning the ceiling will not be immediately noticeable. It will take a couple of days for the structure to dry completely. In addition, the likelihood of complete removal of yellow spots using a chemical method is minimal, at least in one step. However, if you mask the damaged area with paint of the right color, then you can postpone more radical methods until the next full repair. That is why it is necessary, before painting over a leak on the ceiling, to choose the right paint - even a temporary solution must be of sufficient quality.

Plasterboard ceilings and stains after the flood

For the arrangement of ceiling structures, moisture-resistant drywall sheets are often used, designed for use in conditions of high humidity. However, if we are talking about flooding, then even protected sheets cannot remain intact - gypsum tends to absorb water, so the structure will have to be repaired. There is no single answer to the question of how to remove stains from a plasterboard ceiling after flooding.

If the volume of water was not very large, and the ceiling structure did not interact with it for long, then the repair technology will directly depend on the finish of the plasterboard ceiling:

1. Dye. The soaked layer of paint must be removed before it dries. You need to work carefully - the sharp edge of the spatula may well damage the drywall sheet if it is not handled carefully enough. The dried finish is primed with a water-latex mortar, and gypsum putty is applied on top of it (after another hardening). Next, the coating must be sanded, treated with a primer and covered with new paint. It is worth remembering that even with the right paint, the damaged area will still be noticeable.
2. ceiling wallpaper. When the ceiling is flooded, the wallpaper pasted on it usually peels off and becomes covered with red spots. It will not be possible to restore their original appearance by any methods, ranging from trying to simply remove stains and ending with replacing the damaged area. The simplest solution is to return the dried wallpaper to the repaired plasterboard ceiling and paint it.

Sometimes plasterboard ceilings are used without finishing. Of course, such situations are extremely rare, but you need to be aware of them. When flooding, the primary task is to restore the original technical characteristics of drywall, and not its visual data.

When figuring out how to remove rust from the ceiling after a leak, you need to immediately pay attention to the most obvious way to solve the problem - the complete replacement of the damaged sheet. However, you can also replace a separate piece of drywall, for which you first have to cut out the damaged area and fix wooden bars (or metal profiles) on the floor, to which you can attach a patch.

The patch is cut in such a way that a gap of about 5 mm remains around the entire perimeter after installation. Having fixed this fragment with wedges, you need to align it with the rest of the ceiling structure. To fill the joints around the perimeter of the patch, a special mixture is used. After the mixture has completely solidified, the wedges are removed, and all remaining irregularities are sealed with putty.

PVC tile repair

PVC tile itself has good water resistance, so flooding the ceiling will not affect performance. This statement does not apply to the visual side of the issue - spots on tiles appear in the same way as on other materials. It will not work to wash the tile, because the dirt is absorbed into it due to the low density of the material.

However, you can get rid of the problem even in this case - all you need is to perform the following series of operations:

• First you need to thoroughly wash the tile using foam rubber and detergents (compositions with chlorine can also be used);
• Then the tile is primed with a latex composition, due to which a protective film layer is formed on the material;
• When the primer dries, the tiles can be coated with water-based paint in a suitable color.

The technology is quite simple and almost completely copies the algorithm for conventional painting of ceiling tiles. To understand the details, it is worth reading an article on this topic.

Repair of stretch ceilings

It also happens that the neighbors flooded the stretch ceiling, and something needs to be done about it. Stretch ceilings, although considered one of the most resistant to leakage, are still susceptible to water. Even if the volume of water was not very large, and all the consequences of flooding have long been eliminated, yellow spots on the stretch ceiling can still appear. The fact is that traces of water do not appear immediately, gradually appearing on the canvas.

The most common conditions look like this - a special elastic film is used as a canvas, and the reason for the appearance of red spots is the ingress of water from the apartment from above. The simplest option for repairing damage is a suitable stretch ceiling cleaner. Such products are available in a variety of formats - gels, sprays, various solutions, etc. You must use a cleaning agent strictly in accordance with the instructions.

If there is no opportunity to use such means, then you will need to think about how to whiten the ceiling using improvised means. For example, you can make a tampon from gauze and cotton. Such a swab is wetted in a 10% solution of ammonia, after which they need to wipe the stain with a call to clean areas. To complete the work, you will need to wash the entire ceiling with ordinary detergents - then the surface of the ceiling will look uniform.

Another good option is soda ash. It is diluted with water to a 5% solution, after which the resulting composition is applied to the contaminated areas of the ceiling. The dried solution is washed off the ceiling surface with warm clean water. However, if we are talking about using a film ceiling for cleaning, then most suitable products will do - you can’t use unless aggressive compounds. It's all about the smooth surface of the stretch ceiling, which is quite easy to clean.

If a fabric cloth was used to decorate the ceiling, then the stain cleaning process may be delayed. The list of acceptable products is the same as in the case of film materials - but they can only be applied and washed off with soft-bristled swabs. Detergents should be designed for delicate work. To get rid of very strong pollution, it would be better to replace the canvas or contact a specialist.

Conclusion

Ceiling flooding is a serious problem that can cause characteristic yellow spots on the ceiling surface. There are several ways to solve this problem, so before you eliminate the stain on the ceiling, you need to take into account the features of the overlap and finish. If the overlap itself remains intact as a result of the leak, then the problem will be purely cosmetic in nature, so it will be possible to get rid of it both by fairly radical methods and by temporary methods that only mask the damaged areas.

The most sophisticated interior of the room loses its appearance when yellow spots appear on the light background of the ceiling. Usually their appearance is associated with water leakage through the ceiling as a result of some kind of accident. Neighbors sometimes heat in apartment buildings, and in private roofing, over time, it loses its tightness. Since most people are not interested in causes, but in eliminating the consequences, it is worth considering in detail how to get rid of yellow spots on the ceiling of a room.

Where to begin?

Tip one: do not rush to conclusions, be patient and follow this algorithm:

1. Make sure that the cause of the stain is corrected and that water leaks through the ceiling do not continue.
2. Examine the nature of yellow spots and choose a remedy. Do not rush to paint them right away.
3. Perform removal and, if necessary, finishing work.

If the place where the yellow spot appears continues to dampen, then the flow of moisture is clearly not stopped. This does not have to be flooding; for the appearance of a visual defect, water dripping onto the ceiling is sufficient. Such leaks are often observed in the corners of the bathroom and toilet, where the water coming from the neighbors has already “plowed” its way. The same with a leaky roof of a building, moisture can seep inside in small portions in inconspicuous places.

Not so bad when the spot is dry and has yellowish edges. Perhaps he can be easily defeated by folk remedies. It is more difficult if rust appears on the ceiling, then you will have to work hard so that the yellow stains do not appear after some time. There are also grease spots, but they have nothing to do with leaks.

FOR REFERENCE: RUST COMES FROM THE REINFORCED FRAME OF THE FLOOR PLATE IN CONTACT WITH MOISTURE AND AIR

Ways to fix the defect

A dry spot with yellow edges can be removed with a caustic bleach called Whiteness. Putting on rubber gloves and wetting a piece of foam rubber with "Whiteness", you need to thoroughly wet the unsightly stains on the ceiling. Then let the surface dry and, if the result is positive, repeat the operation 2-3 times, sometimes it helps well and the stains disappear.

Surface cleaning

In the case of rust or fungus that has appeared, bleach will not help. The issue will have to be resolved radically, up to repainting the entire surface. Applying paint in one place is advisable for recent repairs, otherwise the difference between the new and old coating will become noticeable. The procedure is as follows:

• cover furniture and household appliances with plastic wrap;
• clean with a spatula the place where the stain appeared, removing the layer of paint and putty to the very plate;
• treat rusty stains on the stove with a solution of copper sulfate or citric acid and wait until the iron oxide dissolves (the stains change color);
• wash off the acid with water and dry the treated area well.

TIP: WHEN WORKING IN THE AREA OF THE CHANDELIER OR OTHER PLACES WHERE THE ELECTRIC WIRING IS, DISCONNECT THE ELECTRICITY IN THE HOUSE

Ceiling putty

After drying, it is necessary to apply an antifungal primer Ceresit CT99 or similar with a brush, followed by a deep penetration primer (Ceresit CT17). Between applications it is necessary to withstand the time interval indicated on the package. And the last step is to make finishing work by applying a layer of putty and new paint. Before painting, the hardened putty is leveled with sandpaper.

By painting the area of ​​the ceiling where there was a yellow spot, you risk getting a new defect, and here's why. A conflict between new and old paint is possible, as a result of which the coating may swell and peel off at the contact boundary. Hence the recommendation: clean off the old paintwork over the entire area and re-paint the ceiling with a roller. Another option is to paste over the surface with wallpaper or polymer tiles.

Other types of ceilings

The previous section describes the removal of stains resulting from flooding or leakage through a standard concrete slab covered with putty and paint. But now in apartments the ceilings are trimmed with other materials:

• suspended drywall systems;
• stretch ceiling;
• plastic panels.

Ordinary drywall absolutely does not tolerate contact with moisture and, after getting wet, must be replaced. The moisture-resistant version of the material is also not designed for water to flow onto it. Worst of all, the leakage of accumulated water occurs at the junction, which is why you have to change 2 adjacent sheets. But do not rush, it is better to first cut out the material that has become unusable. Check if a small piece of drywall can be inserted into its place by screwing it to the lintels between the grid profiles.

IMPORTANT: DRYING AND PROCESSING THE CONCRETE BASE UNDER THE FACING IS ALSO NECESSARY, OTHERWISE THE FUNGUS WILL APPEAR IN THE PLACE OF STAINS

Removing rust stains from plastic can also be difficult, but changing 1 or more panels is not difficult. The main thing is to match them to the color of the old ones, for which the panels must be thoroughly washed. There will be no leak spots on stretch ceilings, but after the bubble is eliminated, the material may deform and not return to its original state. Here you can not do without the help of specialists, they will correct the tension coating or replace it entirely.

Often there are situations when various yellow spots or stains appear on the ceiling or walls.

We find out the reason for their appearance

Before you remove the stains that have appeared on the surface of the ceiling, you need to find the cause of their appearance. This will determine how they are removed. This may be damage to the roof on the roof, high humidity, dampness, poor ventilation or lack of it, but most often this happens after flooding by neighbors from the upper floors.

In our case, the batteries were turned off in the middle of winter. The risers are plastic, and the neighbors did not notice that they had a pipe flowing at the junction. We see the result in the photo.

We use chlorine-containing products - checked by the editors

So, we had to remove yellow stains from the surface of the ceiling after water leaked from the upper floors. The simplest method was chosen - bleaching with "Whiteness" or another chlorine-containing agent.

Ideally, using a spatula, carefully clean the area from the top layer of plaster. Then, after complete drying, finishing work will be required.

But in our case, this was not necessary, the whitewash did not “lag behind”, the stain was even, smooth, it only remained to bleach it. Here is our step by step algorithm of actions.

Pour “Whiteness” into a convenient small container, moisten a foam sponge in it.

Apply with the soft side to the stain, fixing for 5-10 seconds. Walk like this over its entire surface.

Wait for the area to dry completely and repeat the procedure again. As soon as the sponge becomes dirty, it must be changed.

The method is quite laborious, but you can do it slowly, we stretched it out for almost a week. We processed it - let it dry, the next day, in the morning and in the evening, we went through “Whiteness” again, etc.

After the first treatment, and even the second, third, it seemed that this method did not work. But gradually the spot began to lighten.

Yes, there was a specific smell, especially in the early days, but it passed quickly.

Note: after processing the ceiling, do not open the vents or windows for ventilation, everything can dry out with stains and you will have to remove them as well.

Removing water stains mechanically

To get rid of them, you can resort to a mechanical method by doing the following:

1. From the problem area with a spatula, clean the layer of whitewash, paint, plaster to the base coat.
2. Wipe the cleaned area with a damp cloth and wait until the ceiling is completely dry.
3. Use sandpaper to clean up all the bumps.
4. Get rid of existing dust with a brush.
5. Apply a coat of primer with a roller.
6. After the final drying of the area, apply a layer of putty.
7. After drying the ceiling, clean it with sandpaper, if necessary, prime again, and paint or whiten.

To remove the yellow spot from the ceiling, everyone chooses the right way for himself. As you can see, in some cases, you can independently cope with a similar problem.
