How to remove the yellow spot on the ceiling

Removal of yellow spots from the ceiling, usually formed near rusting sewer or water pipes (as well as in the case of flooding by neighbors from the upper floors), is not an easy task that requires certain skills and abilities. To call for a specialist to perform the work in some cases the only right decision. But often, having made some efforts and having spent a little time, it is possible to liquidate a spot independently. The way to remove the yellow spot on the ceiling after a leakage depends on the arrangement of the ceilings themselves, which are stretch, plaster, plasterboard and tiled. These are the most popular types of ceilings, which are repaired in various ways. Consider each of the options in more detail.

Repair of the plaster surface

Most often after flooding, only a certain part of the coating becomes useless. Usually these are joints of the bases, places of electrical wiring and other weak points.

Plaster ceilings are of two types:

• a wooden support beam, upholstered with shingles (a narrow wooden plank) on which a layer of plaster is applied;
• concrete floors, evened with a putty and painted with paint.

Prepare everything for putty

First, consider the repair of the concrete ceiling, for which you will need the following tools:

• spatulas;
• emery cloths and paper;
• respirators;
• rollers and brushes;
• industrial hair dryer;
• spotlights.

It is necessary to prepare in advance the materials with which the yellow spot will be embedded:

• putty;
• primer;
• paint.

Correctly select paint

1. Repair of the ceiling begins, as a rule, removal of water damaged area. But before removing the soaked layer, it must be dried. To do this, remove the wet paint and putty with a spatula by cleaning the area to the concrete base. Then blow-dry the leak.
2. If water has leaked in the place of the electrical wiring, then the room must be de-energized before starting work. In this case, the base is dried naturally or with a building dryer connected to another branch of the electrical grid.
3. It is necessary to clean the damaged area When the surface to be repaired is dried, you need to do a scrubbing that is done with emery paper. It is best to do this work in a respirator (or a mask purchased in a pharmacy). Scraping should be done very carefully so that no traces of old paint or putty remain. The edges of the layer remaining on the ceiling should preferably be smoothed, so that the joints are not sharp.
4. Next, using a vacuum cleaner and a brush, the construction dust is removed and you can proceed to repairing the damaged layer.
5. The surface is primed before applying the putty. This will relieve it of the remaining dust and improve the adhesion of the layer of plaster with concrete. The primer is applied twice, while it is desirable that it does not fall on the uncorrupted areas of water.
6. Putting the problem area After the primer has dried, putty is applied to the prepared area. The material must fit the surface to be repaired. On the package are usually listed all the characteristics of the mixture. But the trial layer is still necessary to do. To do this, dilute the slightly dry mixture with water until a homogeneous mass is obtained, which is applied to the place of the joint between the intact layer and the cleaned surface (approximately 5 * 5 cm). If the layer dries out smoothly, without the formation of bubbles and cracks, then you can continue to work.
7. After the applied solution has dried, you should level the surface with emery paper, cloth and a spotlight, which will help bring the layer to a perfectly smooth state.

Grind

Before you paint the ceiling, you need to choose the right paint composition. For example, some colors are not allowed to overlap. Will have to repaint the entire ceiling, and not just the damaged area. Because the new layer will be different from the old one anyway. The procedure is performed with a roller and brush.

We repair the plasterboard ceiling

Water is one of the most dangerous enemies of drywall. It suffers from moisture more seriously than other types of surfaces. Water instantly destroys the structure of drywall, it becomes damp and yellow for a short time, so the sooner the measures are taken to repair the ceiling, the better.

Look inwards and determine the extent of damage

1. You need to expand the leakage site to remove water from the inner space. This can be done with a screwdriver, knife or other suitable tool, after substituting any container for collecting water.
2. The damaged place will have to be cut completely, because from the bottom it is impossible to determine the scale of the problem - how badly the material has suffered from the inside. After the hole expands so that it can be looked into, with the help of a mirror and a flashlight it is necessary to examine the entire sheet, having determined the size of the damage. You can tap a sheet from below: a dull sound will report a drywall damage.
3. The joints and seams are most often affected. Sometimes it is easiest to replace the entire sheet of material.
4. A new one is installed in place of the deleted sheet. All further work is performed in strict sequence: stripping, priming, puttying, leveling the layer, painting.

Leakage on stretch ceilings

How much the stretch ceiling will suffer from leakage depends on the coating. For example, water can cause serious damage to a fabric surface, and the ceiling will have to be completely replaced. But there are such types of finishes, which the water does not cause much damage. The ceiling just dries out and takes on the original appearance. Sometimes it may require cosmetic staining.

Vinyl ceiling leaks

Leakage is not dangerous for vinyl ceilings, but they are able to collect a large amount of water without passing it down. The maximum that you have to do is remove the accumulated water. Installers can do this job best. But if the case does not tolerate delay, then you can try to drain the water yourself.

Stretch ceiling will save from flooding

On vinyl ceilings there are decorative inserts having a connecting seam. Usually they are installed in the corners. After the seam is found, the insert can be pulled out. Before the procedure, the room should be heated to 40⁰ C. After the water has been drained into the container, it is necessary to dry the interior of the ceiling, and only then insert the decorative insert in place.

It is easiest to “fix” the ceilings made of PVC panels after a leak, which the water does not cause much harm, and it can be drained temporarily by removing one of the planks.

Considered options, how to repair the ceiling after flooding, remove yellow spots or prevent their appearance, will help to cope with the problem of leakage yourself. But do not forget that sometimes still not do without the intervention of specialists.
