Video on removing yellow spots

Situations often occur when various yellow spots or stains appear on the ceiling or walls.

We find out the reason for their appearance

Before removing stains from the ceiling surface, it is necessary to find the cause of their appearance. The method of removing them will depend on this. This may be damage to the roof, high humidity, dampness, poor or no ventilation, 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 made of plastic, and the neighbors did not notice that a pipe was leaking at their junction. We see the result in the photo.

We use chlorine-containing products - verified by the editors

So, we had to remove yellow stains from the surface of the ceiling after a water leak from the upper floors. The simplest method was chosen - bleaching with “Beliznaya” or another chlorine-containing product.

Ideally, use a spatula to thoroughly 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 “fall behind”, the stain was even, smooth, all that remained was to bleach it. Here's ours step-by-step algorithm actions.

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

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

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

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

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

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

Note: do not open vents or windows for ventilation after treating the ceiling; everything may dry out with streaks and you will have to remove them as well.

We remove water stains mechanically

To get rid of them, you can resort to mechanical method by following these steps:

1. WITH problem area Use a spatula to clean the layer of whitewash, paint, and plaster down to the base coating.
2. Wipe the cleaned area with a damp cloth and wait until the ceiling is completely dry.
3. Use sandpaper to smooth out any uneven surfaces.
4. Use a brush to remove any existing dust.
5. Apply a coat of primer using a roller.
6. After the area has completely dried, apply a layer of putty.
7. After drying the ceiling, sand it with sandpaper, prime it again if necessary, and paint or whitewash it.

To remove the yellow stain from the ceiling, everyone chooses for themselves the right way. As you can see, in some cases you can cope with this problem yourself.

This may come in handy: .

Leaks on the ceiling, formed after flooding with water from the upper floor or a leaky roof, are, unfortunately, not uncommon. The ceiling immediately loses its aesthetic appearance and requires repair. Before starting repairs, it is imperative to eliminate the cause of water leaks, otherwise the repairs made may be in vain, and the next rain may ruin all the work.

I also had the fate of doing repairs to eliminate smudges on the ceiling near the window as a result of a roof leak. Finally the roof was repaired and renovations could begin. This is what the ceiling looked like before the renovation.

First, you need to use a narrow metal spatula with a blade width of 4-5 cm to remove the damaged paint or whitewash to the plaster. Before work, the working edge of the spatula must be sharpened like a knife blade, with a block or sandpaper. Then the work will be easier. The steel plate of the spatula should be thin and elastic, bending during operation, as in the photo.

If the plaster moves in places, then it is necessary to remove it too. There is a simple repair rule: everything that does not adhere well to the wall during its repair must be removed. If there are cracks on the surface to be repaired, but the plaster is holding firmly, then they must be expanded, that is, a rectangular groove with a depth of at least 5 mm should be made along the crack line. If the crack is simply erased and painted over, then after a while it will appear in the same place again.

Since after removing the whitewash the plaster had to be removed in some places, it was decided to first apply a layer of Rotband. This is an excellent leveling solution, which is recommended to be applied in a layer of 5 to 10 mm thick; it adheres well to the ceiling surface, is moisture resistant, and is suitable for leveling walls even in bathrooms. Although the recommended application layer is indicated by the manufacturer from 5 mm, as my experience has shown, Rotband, even when applied with a thickness of 1 mm, lays down perfectly and holds tightly. There were also traces of rust in several places on the wall. I didn’t have copper sulfate or other chemicals on hand, so I hoped that with the help of Rotband it would be possible not only to level the walls and ceiling, but also to get rid of rust stains.

But expectations were not met and in several places after the Rotband hardened, traces of rust stains appeared. While Rotband was liquid, the rust moved through the water into its layer.

The question arose again of how to get rid of rust stains. I came to the idea that if you cover the rust spots with a waterproof film, then the surface of the wall can be puttied with water putty without fear of rust stains penetrating into it.

I had PF paint and some epoxy resin available. I decided to use epoxy resin, since after a couple of hours after application it hardens and the repair can continue.

It is difficult to apply epoxy resin to Rotband, as it is very thick. But if after mixing the components you add a little acetone to the epoxy resin and mix it, then it becomes quite fluid and well absorbed by porous materials. All that remains is to paint over the rusty spots with a brush. If you dilute any paint or varnish of the NC or PF type with an appropriate solvent to a liquid consistency, then they are also suitable for isolating rust stains, but it will be possible to continue the repair only a day later, after the applied coating has completely dried.

After covering the rust spots with epoxy resin, they showed up even more, but were now securely covered with a waterproof film. After the epoxy resin has hardened, you can begin finishing putty these places without fear reappearance rusty spots.

Bye epoxy resin hardened, the obvious bumps and protrusions of the rotband on the surface of the walls and ceiling were removed with sandpaper.

By doing repair work on local areas of the ceiling, when removing a layer of paint, when sanding, to prevent the spread of dirt and dust throughout the room, I place a tray ( plastic cover from an old record player). It’s true that it’s not so convenient to work with, but almost all the dirt remains in the tray.

If you wish, you can not buy a new one, but make your own cornice to your liking, as described in the article on the site

Floods and even minor leaks caused by excessive rainfall, failure of plumbing system or the carelessness of neighbors above - a serious test for the ceiling. Even the most modern coatings cannot cope with moisture, reacting negatively even to short contact. You can independently remove stains on the ceiling from leaks in several ways without replacing the coating with new ones.

Mechanical action - simple and reliable

A simple method to get rid of leak stains on a plasterboard or plasterboard ceiling. decorative plaster- with a spatula. The method does not require the use special means, is considered quite fast, effective and safe for coating.

To remove stains, use a spatula and gently remove upper layer finishing, being careful not to damage the base. The treated area is additionally wiped with a sponge soaked in water and allowed to dry.

Apply several layers to the prepared surface. soil mixture deep penetration, also giving them time to dry. The next stage is finishing with putty, followed by leveling and sanding. The sanded area is re-primed, dried and painted with paint to match the color of the main coating. If the shades after finishing the area being restored and the main ceiling are different, it makes sense to re-coat the entire ceiling with a new layer of paint. Maximum effect This can be achieved if you paint the ceiling in two layers.

You can also use a special grinding tool that removes the paint layer.

You can do it even easier if the stain is from a leak small sizes. The area of ​​contamination is washed away, primed and whitened in two layers.

Aggressive cleaning methods

After a serious flood and the ceiling has completely dried out, it is worth trying to remove deeply ingrained stains with chlorine-containing products. Their advantage lies primarily in accessibility and efficiency.

To prepare the product at home you will need:

• White (can be replaced toiletry product with chlorine or bleach);
• protective gloves;
• foam sponges;
• container for stirring.

The procedure begins by cleaning the ceiling from old layers of finishing with a spatula. Clean the treated area with a sponge soaked in white, always using rubber gloves. To enhance the effect, apply the sponge to the stains and stains for at least 5 seconds, after which the procedure is repeated. Sponges painted rusty are replaced with new ones.

This scheme is continued until the spots become barely noticeable. After this, the ceiling is given time to dry, the room is ventilated and finishing work is completed.

You can replace bleach or toilet cleaner with chlorine with hydrochloric acid heated to 40 degrees. Treat stains with a solution similar to chlorine.

Copper sulfate in the fight against rust - how it works

When painting over stains on the ceiling using previous methods does not work due to the serious consequences of a large-scale accident in multi-storey building, worth a try effective remedy based on 10% copper sulfate. To prepare it you will need:

• copper sulfate;
• laundry alkaline soap;
• drying oil;
• bone glue;
• brush or foam sponges;
• protective gloves.

Just as in previous cases, areas requiring repair are cleaned of a layer of paint or plaster. The mixture prepared from the above ingredients is poured into a convenient container and the stains are treated using a sponge or brush. As soon as the surface of the ceiling becomes white again, it is primed, puttied and finished.

To prevent stains from appearing again, a waterproof film is created on their surface even after treatment with vitriol.

In case of tension fabrics The solution to the problem is to call a specialist. The master will drain the water and clean the canvases, returning them to their original appearance.
