How to remove yellow spots on the ceiling after a leak. How to remove yellow spots on the ceiling: types and methods of elimination How to remove stains from the ceiling after flooding

This problem is familiar to many residents of high-rise buildings. It can seriously affect the state of the wallet, because we are talking about flooding the apartment. It can be caused by neighbors living upstairs or a leaky roof. In any case, the appearance of yellow spots above the head always causes unpleasant feelings. It is useless to paint over them, because over time they show through again. Then you have to decide whether to repair the ceiling after a leak with your own hands or call in specialists. Our article will help you do without them.

First of all, you should shut off the water supply and wait until the wet surface dries well. If the leaky roof became the culprit of the problem, then before the start of repairs in the apartment, it must be “patched up”.

Repair of suspended structures

Stretch ceiling

This is exactly the case when the investment justifies itself. Although the tensile structure device is more expensive than other types of finishes, it eliminates many problems in the future. For example, when a not very large leak hits a stretch ceiling, it only sags under the weight of water and prevents the liquid from pouring into the room.

Stretch ceiling is a reliable protection for your property

In this situation, the losses will be minimal, since the film will protect the floor, walls and furniture from water. All that is required from the residents of a flooded apartment is to block the water riser and call the master. He will pump out the accumulated water, rinse and dry the film, and then stretch it again. That's all!

Plasterboard ceiling

With suspended structures, everything is much more complicated. Eliminating the consequences of a leak can cost a lot of money and require a lot of labor. Everything will depend on the amount of water that has fallen on the ceiling and the complexity of the suspended structure. Naturally, the greater the leakage of the ceiling and the cost of finishing materials, the more significant the repair costs will be.

But you should not panic, because almost everything in our world is subject to restoration. A damaged plasterboard ceiling can be refilled, sanded, primed and repainted.

Such stains will spoil the mood of any tenant.

painted surface

How to fix a leak on a ceiling that is covered with whitewash or paint? The main thing is to follow the recommendations below and then you can do the work yourself.

First of all, remove pieces of putty and peeled paint from the dried surface with a spatula.
Then you need to discolor the yellow spots. How to process the ceiling after a leak in this case? Normal white. Apply the liquid to the sponge, then apply it to the yellowed area, press down and hold for a few seconds. After some time, the yellowness should disappear.
After that, be sure to treat the surface with a solution of copper sulfate or a solution of isosulfate.
Wait a few days, if the spots do not reappear, you can do further finishing.

On a note! Not all putties equally fall on the remnants of glossy paints. Therefore, it is better to putty the treated surface through a reinforced fiberglass mesh (mesh size 2.5x2.5 mm).

Paint the entire surface of the ceiling, not just the areas where there were stains. If yellowness appears immediately after this, cover it with paint a few more times. Water-based compositions are not suitable in this case, since after them the spots appear again. When using oil dyes, the color of the ceiling may only slightly change.

Thoroughly sand swollen plaster and loose paint

Ceiling tiles

Such coverage is in a winning position. The material for ceiling tiles is polystyrene, and moisture is not terrible for it. The question of how to remove a leak on the ceiling in this case is easily solved. You just need to blot the wet area with a napkin or sponge.

Note! If water has spoiled the putty or plaster under the tiles, the coating will have to be dismantled. Subsequently, the tiles are easily and quickly installed in their original place.

If you do not have the desire to engage in repair work, you can approach the problem creatively. For example, places where yellow smudges remain can be veiled with an original element. The main thing is not to be afraid of experiments and approach the problem creatively. As a result, the result may be better than with the standard solution.

Now you understand what to do if a leak on the ceiling, after all, has appeared. The main thing is not to lose heart, because there is always a way out! Good luck!

I greet the distinguished assembly and ask for advice. Most recently, he made a good repair in the apartment, in particular, he leveled and painted the ceilings with rather expensive paint. And now, due to a pipe break at the upper neighbors during the start of heating, all my work and expenses were in vain. Large yellow stains flaunt on the surface in one of the rooms. Tell me how to remove yellow spots with minimal cost?

I don’t want to quarrel with my neighbors and I won’t - they are very elderly people. They have no money to compensate, and they themselves will not do such a job. I'll have to do everything again with my own hands.

How to remove yellowness and smudges after flooding

Hello, Alexander. You're out of luck, sorry. And to tinker to return the ceiling to its former appearance, it will take a lot.

The main thing is that this situation does not happen again, so it is advisable to get the management company to revise and overhaul all the old pipelines in the house.

Ways to eliminate yellow spots

The nature of the spots may be different. If it's just dirt from washed out cement, then getting rid of it will be the easiest. Worse, if water oozed through old rusty pipes, metal mortgages and fittings, causing them to corrode and washing all of the above to the surface.

It is important. There are several ways to get rid of yellow spots on the ceiling, but before applying them, you must wait until the ceiling is completely dry and clean it to the ground from the old coating.

Method one - putty

Whatever your ceiling is finished with, the coating from the damaged area will have to be ruthlessly cleaned using a spatula or power tool. It is desirable to free the ceiling even from plaster. Then it must be rinsed with clean water and allowed to dry.

Remove the consequences after flooding and whiten the surface

Further instructions are:

Treat the exposed area with a deep penetration primer;
After it dries, level the surface with putty. Its appearance and number of layers depend on the thickness of the finish on the undamaged areas, since you need to bring the entire ceiling to one level. In any case, a thin layer of finishing putty is applied last;

Sand small defects with a plaster mesh or sandpaper;
Reapply primer;
Paint the repaired area the same color as the rest of the ceiling.

Method two - whitening

If stains remain on the ceiling even after removing all the finishing layers, there is a risk that they will show through the new coating over time. How to remove yellow spots on the ceiling in this case?

Bleach containing chlorine. It can be a plumbing gel or a laundry bleach. But you will not find anything better than ordinary whiteness. Moreover, the price of this tool is mere pennies.

So, after completing the required procedures, we do the following:

We put on old clothes and rubber gloves;
Pour whiteness into a bowl;
We moisten a sponge in it and treat the stain until it disappears, or brightens a lot;

Advice. If the sponge has turned red from rust, and the stain is still in place, change it to a new one. You may need to change it several times.

Wait for the surface to dry and finish it as described above.

If the whiteness did not cope with the stains, prepare a mixture of 250 g of 10% copper sulfate, the same amount of bone glue and grated laundry soap. Add 40 g of drying oil to it and treat the ceiling with this composition using a roller.

Method three - coloring

It is guaranteed to prevent the appearance of yellow spots on a freshly repaired ceiling, their isolation with an impermeable film will help. Such a film on the surface is created by oil paints.

What should be done:

Rinse stains with 10% copper sulphate;
Prime and putty the treated area;
After the putty has dried, paint it with oil paint;

Apply a layer of finishing putty;
Paint the ceiling or whitewash it with the same composition as the rest of the surface.

Alternative Methods

All the described methods complicate life, as they require protecting walls, floors and furniture during repairs, diluting dirt and dampness. If you are not ready for such difficulties, there are other ways to rid the ceiling of leak marks.

For example, you can paste over it with wallpaper or ceiling tiles. Or install a stretch ceiling. But in any case, you first need to make sure that the base is completely dry and a new flood does not threaten you.

Otherwise, under such a finish, mold can start, which is even more difficult to deal with.

Conclusion

There are a lot of videos on the Internet on this topic, filmed both by the owners of flooded apartments and by professional finishers. You can see one of them on this page.

By learning how to remove yellow stains from the ceiling, you can decide whether to do it yourself, hire a specialist, or use more reliable and faster alternative methods.

Causes of spots
Spots from flooding
oil stains
Rust spots
Smoke and soot stains

Capital repairs of an apartment require a lot of effort, but how pleasantly pleased with the result! Sparkling white ceilings, transformed windows and floors, new beautiful wallpapers look favorably against the backdrop of new furniture and high-quality household appliances. But, unfortunately, the joy often does not last long, because the interior is spoiled by yellow spots on the ceiling that have come from nowhere, which become more and more distinct every day. What to do?

Causes of spots

First you need to figure out what was the prerequisite for the formation of unpleasant yellow stains. Knowing this, you can choose the most effective way to remove stains. Provoking factors can be:

Old pipeline system. Corrosion damages the metal, which forms rust. The flow of water leads to damage to the system and the ingress of liquid onto the ceiling. The yellow rust spots on the ceiling have to be removed regularly until the pipes are repaired or replaced.
old roofing system. Precipitation flows through the leaky material and seeps onto the ceilings of apartments located on the upper floors. To get rid of yellow spots permanently, it is necessary to replace the roof covering with a new one.
Soot and smoke. In this situation, the human factor plays an important role. An unattended pot of food on fire, children playing with fire, etc. can lead to heavy smoke in the living space and even a fire, resulting in extensive yellow spots on the ceiling.
Raw conditions. In an environment of high humidity, not only red stains appear on the walls and ceiling surfaces, but also mold, which is removed with great difficulty.
The carelessness of the neighbors from above. Upstairs residents can easily flood downstairs neighbors by leaving a faucet running or letting water leak from leaky pipes.

To quickly solve a problem, people use the method of painting over, which leads nowhere because the cause has not been eliminated. Ugly stains again appear through the painted places. It is necessary to understand the situation before choosing a solution on how to remove yellow spots on the ceiling, because otherwise efforts and time will be wasted.

Spots from flooding

After the cause of flooding by neighbors from above has been eliminated, you need to think about how to remove the yellow spots on the ceiling after flooding, because it is better to do it once and with high quality than to constantly finish what you started. You will need:

chlorine-containing agent (the most common, cheap and effective is "Whiteness");
thick rubber gloves;
solution container;
2-3 foam sponges.

"Whiteness" is poured, hands are protected with gloves, a sponge is at the ready - now you can start processing. After wetting the sponge in the solution, you need to press it against the yellow formation for 5 seconds, then moisten it again and apply it to those places that have not yet been processed. The lower part of the sponge will gradually turn red. It needs to be changed and manipulations continued until the yellow stains on the ceiling brighten.

oil stains

In a situation where greasy stains are found on the coatings, it is not easy to figure out how to remove yellow stains on the ceiling, because the oil soaks through all layers of plaster, and surface treatment causes unsightly formations to reappear on the surface. For work you need:

deep penetration primer;
spatula 5-8 cm wide;
water-based paint;
roller or brush;
paint container.

Damaged plaster is removed with a spatula. Then a primer is applied in one layer. You have to wait until it dries completely. The brush or roller is dipped into the water-based paint, its excess is removed, and then the masking compound is gently applied to the work surface with gentle movements. The ceiling is painted over several times until the stain disappears completely.

Rust spots

Old high-rise buildings, in which dilapidated piping systems lead to constant gusts and leaks of water, require an enormous amount of effort to maintain them properly. Tenants also suffer, looking for ways to get rid of yellow spots on the ceiling, because the sad story is repeated many times. Red stains appear again and again. For effective treatment of contaminated areas you will need:

solution of copper sulfate 10%;
container for vitriol liquid;
rubber gloves;
sponge or brush.

To prepare the mixture, it is necessary to mix 250 g of copper sulfate, 250 g of laundry soap shavings, the same amount of bone glue, 40 g of drying oil solution.

A brush or roller is dipped into this composition and the rust-damaged area is treated.

Yellow spots on the ceiling. How to remove quickly

Smoke and soot stains

The situation in a situation where the walls and ceiling are covered with soot and soot is very serious. Yellow spots occupy most of the surface in all rooms. Partial processing is not enough here. It is necessary to completely remove the entire area of \u200b\u200bdamaged plaster. The troubles result in large cash costs and long overhaul work.

Removing red stains on the ceiling is not an easy task, so you should prepare for the fact that the work will take a lot of time. The main thing in such situations is to eliminate the cause of the stains and only then carry out a high-quality treatment of the damaged areas.

Leak stain on the ceiling: remove yellow ones, yellowness remains, how to remove and whiten stains in the bathroom, how to paint over

When removing a stain from a leak on the ceiling, you need to follow some recommendations and then you can do the work yourself. You have just done the repair, you are enjoying the result of the work and the rationality of the investment, when suddenly a negligent neighbor from the top floor, or streams of heavy rain that climbed into the cracks of a leaky roofs, pretty spoil your mood. Flooding. And soon a terrible yellow spot forms on your “brand new” ceiling. What to do? How to deal with this problem? Call the construction team, or try to fix the situation on your own? Decided to fix the problem yourself? Then go!

How to remove yellow spots on the ceiling after flooding

To understand how to save the situation, you need to understand the reason for the formation of spots. It's one thing if the yellow stain was formed from splashes of champagne, which you unsuccessfully opened while celebrating the repair. Or vice versa - yellow stains are the careless work of unscrupulous performers of finishing work. In these cases, removing the yellow marks is not difficult.

Before you start working on removing stains from the ceiling, you need to understand the cause of their occurrence.

But if the stain was formed from a leak in the ceiling of your apartment, or constant humidity in the bathroom, everything is completely different.

The problem is that water got on the engineering structures of your house, rust along with the water "set off" and took shape in a huge spot, or several spots, on your ceiling. Even if the building materials with which your ceiling is finished are dry, but the floor slabs remain damp, then after a while stains may still appear.

Getting rid of unpleasant yellow spots on the ceiling

Are you in trouble - a yellow stain from a leak on the ceiling? It happens to everyone. Say "no" to a bad mood and get down to business!

For finishing work previously performed indoors, you should choose a method that allows you to eliminate yellow spots on the ceiling

There are several ways to eliminate a yellow spot from a leak:

Let's take them in order.

Let's analyze the first way to remove yellow stains from leakage

This method is mechanical. These are cardinal measures that will help you completely get rid of the consequences of flooding your apartment, but laborious.

Before starting repairs using this method, you must have the following construction tools and materials available:

Putty knife;
Fluid sprayer;
Small roller or brush;
Deep penetration primer;
Finishing putty;
Fine sandpaper;
Paint or whitewash.

All collected? Get started. It is necessary to clean off old, damaged paint, putty or plaster with a spatula in the place where the stain has formed. After that, moisten the vacated area and wait a bit until the place of moistening dries. After that, using a roller or brush, apply a primer to the repaired area.

The most common way to remove stains from the ceiling, which does not require the use of any chemicals, is mechanical

After a while, after the primer dries, apply the finishing putty to the exposed area with a spatula, level the surface and wait until the putty sets. Using sandpaper, grind the dried putty and sand the surface irregularities, thereby preparing the ceiling for painting, or other types of finishing work, and prime again.

After the primer has dried, re-paint the ceiling with a roller or brush, carefully choosing the tone of the paint. If the shades of the old and new paint are not identical, you will have to repaint the entire ceiling completely. In order to avoid spots and streaks, we paint the ceiling in 2 layers. If you use whitewash, you need to apply it in two layers after a preliminary primer.

You can just whiten the stain, but only if it is small. In this case, the place where the stain has formed is washed out, primed with 2 layers of primer and 2 layers of whitewash are applied. When applying this method, you will also have to whitewash the entire ceiling.

The second way to get rid of yellow spots on the ceiling after flooding

Let's assume that the situation is not so catastrophic as to clean off the whole ceiling, or you are simply an irresistible optimist and naturalist.

Then you can try the second method - chlorine-containing.

For this you will need:

Any chlorine-containing agent (this can be whiteness, any chlorine-containing bleach, or even chlorine-containing toilet duck);
Rubber gloves;
Goggles (any);
Several foam sponges (depending on the size of the stain) or a small roller for painting;
Container for chlorine solution.

Work with chlorine-containing substances should only be done with rubber gloves.

Before starting work, change into unnecessary clothes, so that drops of the solution, falling on it, do not spoil good things.

To protect your eyes from chlorine, put on your goggles and get started.

First you need to carefully clean the damaged area of the ceiling from the affected finishing materials, primers and plasters. Having done this, put on gloves, pour the whiteness into the prepared container, dip the sponge or roller into the solution and start processing the ceiling. Apply a sponge or roller to the stain and fix in this place for five seconds. Then dip the sponge into the solution again and process again. So it is necessary to process the entire area of the damaged area. When the sponge turns red, it should be replaced with a clean one. In this way, you need to treat the damaged area until the yellowness brightens as much as possible. After processing, ventilate the room, wait until the ceiling is dry, and paint or whitewash it, depending on the type of finishing work applied before.

How to remove yellow spots on the ceiling if the apartment is renovated

If you have a stretch ceiling, then you should call the person who installed this ceiling for you and ask what paint you can paint over this canvas.

It is better to entrust the removal of stains on the ceiling during renovation to specialists

In the case of flooding, drywall ceilings, moisture damage to drywall sheets is usually particularly severe.

In this case, your ceiling will not only turn yellow, but also deform.

Tapping a drywall sheet with a solid object, you should determine the boundaries of the affected area, and try to replace the part of the sheet destroyed by water. Most likely, you will have to replace the entire sheet completely, and then re-do the finishing work.

Of course, you will choose the way to eliminate yellow spots for yourself individually, depending on the building materials with which your home is finished, and the nature of their contact with moisture. But you should take into account the fact that in any case, it is initially necessary to remove the cause of the appearance of yellow spots, otherwise all your work to eliminate them will be in vain and more than once.

Question. We were flooded with upstairs neighbors. Filled specifically. Leaks throughout the apartment, dark water stains on the ceiling and walls in the kitchen, bathroom, hallway and one of the rooms. The wallpaper has peeled off. Please advise how to fix this. From past experience, we know that it is very difficult to paint over leaks, spots and smudges show through the paint, this is especially noticeable on the ceiling. On the walls, the wallpaper also darkens with streaks where the water flowed. Can you recommend something?

Answer. Really dark spots of streaks are quite difficult to paint over or wallpaper. They tend to show through. But there are reliable technologies.

First of all, wait for the walls, ceiling and ceiling to dry completely. This will take at least six months. There is no point in renovating before.

Secondly, remove old wallpaper, peeling paint. If the plaster after pouring began to lag behind or simply became loose, then it must also be removed. If the entire wall has become brittle, then it must be impregnated with a deep-penetrating acrylic bonding primer. The resulting recesses and irregularities need to be leveled. I do it with VGT putty. This putty is excellent for applying and sanding.

How to fix a ceiling after a leak

If the potholes are deep, then putty should be applied in several steps. After the first application, the putty will crack. This is fine. Cracks need to be patched. Sand the resulting surface. Fix small defects with a thin layer of the same putty.

Thirdly, after the putty has completely dried, you need to put a waterproof paint layer so that stains do not show through. The fact is that water-based paints are all porous, they breathe and let water through. Wallpaper also passes water. Dirt goes along with the water. It is dirt and impurities that show through as spots. The easiest way to make a waterproof layer is to do so. Apply universal alkyd or glyptal primer. I use primer Otex (Tikkurila) or white primer GF-021. Then you need to apply enamel PF-115, then another layer of soil. This enamel is completely waterproof. This provides protection against stains. Water-based paint or wallpaper paste won't stick on top of the enamel, so a second coat of primer is needed. In fact, GF-021 is also waterproof, so if you use this primer, then just two layers of primer are enough, enamel can not be applied, but for reliability it can be applied. If Otex is used, then it is necessary to apply enamel.

It is possible to apply enamel on the first layer of primer after 4-6 hours. The second layer of primer on the enamel can also be applied after 4-6 hours. Dry the last layer of soil thoroughly (preferably 24 hours). The application of water-based paints or wallpaper paste on insufficiently dried alkyd or glyphthalic primer leads to curdling of the paint or glue (characteristic lumps form).

All! You can paint the ceiling or walls, glue wallpaper. Stains after such a repair will not show through.

Spots on the ceiling quite often appear in our apartment or house. This unpleasant moment worries many people. Especially if after a recent repair on your snow-white ceilings they appear from nowhere. Unfortunately, not everyone knows how to deal with this phenomenon, and this article is designed to help you get rid of stains on the ceiling.

To begin with, you should tell you about where the stains come from, because there can be several types of them. This will help you better understand how to clean yellow stains from the ceiling and how to prevent their occurrence in the future.

Types of stains

oil stains

In most cases, they appear from the use of oil paints. Until recently, it was considered very beautiful to paint the ceiling with such paints, they created a durable and easy-to-clean surface. The problem of our time was the fact that oil paints impregnate the surface very deeply, and even after complete washing off from the ceiling, the oil eventually appears on the surface. Removing such a stain on the ceiling is quite difficult.

moisture stains

I think that a long description of their appearance would be superfluous here, because many people have come across them. Someone's roof leaked, others were flooded by neighbors from above, this leads to the fact that a large yellow spot remains on the ceiling after drying. This type of stain is much easier to deal with than greasy stains from oil paints.

rust stains

For new houses and apartments, such spots are quite rare. They form due to corrosion of rebar and pipes in ceilings as the rust travels through the concrete to the ceiling surface. The usual painting with water-based paint will not help. If you have such stains, do not waste energy and money on multiple layers of paint, because in order to completely get rid of them, the surface must be prepared properly.

Fungal spots

The most annoying of all. They not only spoil the appearance of your ceiling, but are also very harmful to health and can cause allergies. Fighting them is difficult and rarely manages with a simple repair of the surface on which the fungus has formed. But even with it you can fight, because on the modern market a fairly wide range of tools is provided to remove it.

Stain removal

Due to the fact that stains on the ceiling can be of different origin, it is logical to assume that the methods for eliminating them are also different. What to do with stains and how to eliminate these "blots" spoiling the appearance of our ceiling.

oil stains

Oil stains, as mentioned earlier, are quite difficult to get rid of.

In this regard, they are usually not deleted, but simply "blocked".

Tip: Grease stains on the stretch ceiling are washed off with a soft, lint-free cloth or sponge using dish detergent.

moisture stains

Residents of apartments often encounter such yellow spots. As you might have guessed, this refers to cases where the upstairs neighbors forget to turn off the tap in the bathroom. Also, in old apartments, the water supply and sewerage systems leave much to be desired and leaks occur quite often.

Residents of private houses are not without this problem, as rainwater or melting snow passes through the old roof. Subsequently, spots are formed, which, even after repeated puttying and staining, still appear on the surface.

How to remove stains on the ceiling:

Spots then rust

The appearance of this type of stain is associated with corrosion of reinforcement and old pipes inside the ceilings. In most cases, they "go out" to the ceiling at the same time as flooding, because moisture is needed for the appearance of rust on the metal.

How to remove stains on the ceiling:

Treatment with copper sulphate.
This method has many supporters and is used quite often. At the same time, there are probably more opponents of this method, they argue that after such a treatment, the spots return over time.
"Toilet Duck".
Human ingenuity has no limits. In the fight against stains, some people have tried using a "toilet duck" with a rust removal function. It is claimed that this method is very effective and leaves no streaks.

Fungal spots

Two factors contribute to the appearance - moisture and stagnant air. Therefore, before proceeding with the fight against the fungus, it is necessary to think about changing the ventilation system in the apartment. In most cases, the fungus appears in winter on cold walls where condensation forms, such places need to be insulated. After all, no matter how you eliminate fungal stains, make sure that they do not have the opportunity to appear again. Otherwise, all your hard work will go to waste.

It is very offensive when, after a recent repair, a neighbor drowns you from above and on the ceiling, even after it has completely dried out, yellow spots suddenly appear, increasing in size.

The reason for this unpleasant event is the interfloor slabs that have not completely dried out.

Even if the plaster on your ceiling is dry, stains can still show through after a while. If the house is old or even new, but the pipes of engineering systems are rusted in the ceilings or the reinforcement in the monolith rusts, it can also show through on the ceiling sooner or later, especially if the corrosion process is accelerated by flooding.

The best way to eliminate the consequences of this event is to make a claim to the upstairs neighbor and ask him to eliminate the consequences of a utility accident. However, it happens that you don’t want to spoil relations with neighbors, and the trouble is not so great. In this case, you can try to eliminate the consequences of the flood on your own.

We will figure out how to remove yellow spots, rust and smudges on the ceiling after flooding and leakage from negligent neighbors.

So, what should you do if yellow stains remain on the ceiling after the flood? When working with any damp ceiling, the first step is to turn off the electricity at the meter. You do not yet know where the water leaked and how close it went to the wiring.

Method 1 - mechanical

This is the most common method that does not require the use of any chemicals. With a spatula, we clean off old paint, putty, plaster, as long as possible or until we remove the damaged surfaces. We wipe the opened area with a damp cloth and wait a bit until the ceiling dries. After that, apply a deep penetration primer with a roller.

We take the finishing putty and apply it with a spatula to the ceiling. We level the surface and wait for it to set. Using sandpaper, we grind surface defects, preparing the ceiling for finishing. Then prime it again with the same primer.

At the end, paint the ceiling again with a roller or brush. If there is any doubt that the shades of the old painting and the new one are identical, you will have to completely repaint the entire ceiling. The ceiling is usually painted in 2 layers.

If you use whitewash, you need to apply it in 2 layers after preliminary preparation. You can simply whiten the stain if it is small in size: the focus is blurred, primed, whitewash is applied in 2 layers.

Method 2, chlorine-containing

So, the flood stopped, the ceiling dried up. How to get rid of traces of disaster and how to remove yellow spots on the ceiling after a leak?

You will need:

whiteness or other chlorine-containing agent (it can be ACE bleach or even toilet chlorine duck);
rubber gloves (put on old clothes so that drops of whiteness, accidentally falling on it, do not spoil your home);
2-3 foam sponges or a small foam roller for painting;
container for the solution (a container for paint is suitable).

First you need to clean the ceiling from previous layers of finishing materials and plaster. Then pour whiteness into a container, put on gloves, moisten a sponge or roller in the solution and proceed to processing.

Apply the sponge to the stain and fix in this position for 5 seconds. Then blot again and process again. Thus, walk over the entire area of the spot.

At the moment when the sponge turns red, it should be changed. Thus, the ceiling should be treated until the spots brighten as much as possible. After processing, you need to wait until the ceiling dries, and carry out finishing work.

Advice. If you have hydrochloric acid on hand, you can treat it with a 3% hydrochloric acid solution heated to 40 degrees.

Method 3, for rust control

It is much more difficult to deal with the consequences of a utility failure if the leak has affected the rusty pipes in the floor slab, and along with ordinary water, rusty particles have leaked onto your ceiling. How to remove rust from the ceiling after a leak?

To effectively process bright red stains, you will need:

10% copper sulfate;
ordinary red laundry soap;
bone glue;
drying oil;
rubber gloves;
roller, sponge or brush.

To prepare the mixture, 250 g of vitriol, the same amount of soap chips, bone glue and 40 g of drying oil are mixed.

Also follows clean the plaster and paint layer to the maximum possible depth. The mixture is poured into a container, the roller is dipped into the mixture and the entire area is processed.

You can simplify this method a little. That is, treat the affected area with copper sulfate, prime, putty and, after puttying, paint over with oil paint. Oil paint forms a fairly dense film on the ceiling, the stain will not show through it again. Then, if the ceiling was previously painted with a water-based emulsion, paint over the entire surface with it.

Important! If the stain appears again and again, until you create a waterproof film in this place, all efforts will be in vain: the yellow spot will appear again and again.

Method 4, to save stretch fabrics

You can not discount the situation when the stretch ceiling and spots on the main ceiling, in principle, do not matter. But if there was a leak and the water was safely drained from the stretch ceiling, yellowness can also appear on the stretch fabric. In this case, you should call the installer and ask what kind of paint you can paint over this canvas.

Depending on the type of canvas, processing can be carried out. Fabric canvases can be dyed up to 5, and sometimes even up to 10 times. PVC films should be cleaned with soapy water or ordinary dishwashing detergent.

In the most difficult case, it will be necessary to carry out treatment with ordinary soda ash. A 5% solution will help clean the canvas, which must be applied to the painted area, wait for it to dry, and then rinse with warm water. This procedure can be repeated several times until the stain disappears completely.

Method 5, to save plasterboard ceilings

The same trouble can befall the owners of beautiful solid plasterboard ceilings. Unfortunately, moisture damage to drywall can be especially severe, because moisture will spread inside the drywall. In this case, the drywall sheet will not only turn yellow, but also swell and deform.

Important! If there is a suspicion that the leak was strong, you will have to pierce the sheet with a knife or a long screwdriver and drain all the water. then proceed to the reconstruction of the ceiling.

Using the tapping method, you should determine the size of the affected area and try to replace part of the sheet. Most often it has to change the entire sheet(which, of course, is dreary and unpleasant, but still possible), and then carry out completely finishing work.

About yellow spots

The easiest way to solve the problem is if there is a leak in the ceiling trimmed with PVC plastic panels and they are left with a yellow coating. To eliminate these troubles, it is enough to wipe the PVC panels with a damp cloth.

There are many different methods, tried and tested, to combat yellow spots. May help in some cases water based stain primer, which is sold in construction hypermarkets.

Someone just paints over the surface with Beckers Nondrop water-based latex paint. Any paintwork material that creates a strong, dense film on the ceiling surface is suitable.

How to remove condensation on the ceiling

Condensation can form on the ceiling in a bathhouse, in a garage, on a loggia, and even in a residential area, if there is unheated non-residential space above it. This is not a particularly good phenomenon, which causes gradual corrosion and structural failure, which must be dealt with.

Condensation usually occurs in poorly ventilated areas and the ventilation system should be checked or installed first. Insulation of the ceiling will help to eliminate condensate. Insulation can be done with mineral wool insulation or extruded polystyrene foam.

If condensate has appeared on the ceiling of the cellar or garage and there is the possibility of access from above, then you can sprinkle the floor with expanded clay, sawdust, or spread the same mineral wool material to insulate the floor from above.

The same method also applies to the case if condensate appeared on the ceiling of a room in a private house, and an unheated attic was on top. In this case, it is enough to insulate the floor of the attic.

Should know

When spots appear on the ceiling, the most important thing is find their cause. Because if you think that your neighbor is heating you, but in fact the leak is caused by a burst of pipes in the interfloor ceiling, no cleaning and finishing work will help you until the representatives of the housing office repair the pipes.
