Secrets of experienced craftsmen on how to remove yellow spots on the ceiling after flooding

Yellow stains on the ceiling are the result of flooding; they not only spoil the interior of the room, but also become a breeding ground for fungus and mold if not treated in a timely manner.

It is necessary to begin eliminating yellow spots after a flood as quickly as possible. The main thing is to study in advance the subtleties and features of the process for different types of surfaces.

If you have a leaking ceiling and want to know how to remove yellow stains on it after a flood, read this article.

Eliminating yellowness

Before you begin to eliminate traces of a flood on the ceiling, you must first assess the scale of the disaster. The choice of upcoming work depends on this.

Painting or whitewashing

The easiest way to eliminate flood marks on the ceiling is to paint over or whitewash the yellow stains.

In order for the new coat of paint to lay evenly, Certain rules must be followed:

1. Surface preparation. To do this, carefully clean off the old layer of decorative coating.

   To ensure that the whitewash does not crumble, but is removed in a whole layer, the smudges are treated with an adhesive composition made from brewed flour (for 6 liters you need to take 3 tablespoons of flour).

2. Ceiling primer.This simple rule ensures better adhesion of fresh whitewash to the rough surface.
3. Apply water-based paint or lime mortar. It is better to choose a new paint that is thick and dense in consistency so that yellow stains do not appear on the freshly painted surface of the ceiling.

The painting method is effective in cases where the flood area is small and the plaster layer is not destroyed by water.

Chemical treatment

Minor traces of a flood on the ceiling can be removed using treatment with chlorine-containing products.

How it's done:

1. The flood area is carefully cleaned with a wide metal spatula.
2. Whiteness (alternatively, you can use bleach or toilet bowl cleaner) is poured into a glass container.
3. Protecting your hands with rubber gloves, moisten a soft sponge in a chlorine-containing product, and then apply it to the yellow spot. Thus, carefully blotting, the entire surface of the yellow stains is processed. After the Whiteness dries, the yellow spot will begin to lighten. The treatment is carried out several times until traces of the flood are completely eliminated.
4. The entire surface of the ceiling is covered with a fresh layer of whitewash or paint.

Mechanical cleaning

The most common way to eliminate yellow flood stains on the ceiling is mechanical cleaning:

• traces of the flood are carefully cleaned with a metal spatula;
• if necessary, cover the cleaned surface with a thin layer of finishing putty;
• the prepared ceiling is primed and covered with a layer of paint or whitewash.

Before applying paint, the primer layer must dry thoroughly. Otherwise, there is a high risk of delamination of materials applied to the ceiling.

Major renovation

In the case where water has destroyed not only the top decorative layer, but also touched a deeper layer of plaster, restoring the original appearance of the ceiling can only be achieved by a major overhaul.

The final result of the work directly depends on compliance with a clear sequence of actions:

1. Remove old paint and a layer of damp plaster from a damp surface with a spatula. It is convenient to carry out preparatory work using a wide spatula. If exposed reinforcement is exposed during the cleaning process, it is also cleaned and covered with two layers of paint.
2. After waiting for some time (the cleaned surface must dry), the rough ceiling is treated with a deep penetration primer. This will help degrease the surface and prepare them for subsequent application of a new finish.
3. Finishing putty is applied to the prepared surface, the layer is leveled and left until the material has completely set to the surface.
4. The dried layer of plaster is sanded and coated with a primer.
5. Using a roller or brush, the ceiling is covered with whitewash or paint.

Rules for removing yellow spots for different types of ceiling structures

When choosing a method for eliminating traces of a flood, a special approach is required:

• tension,
• glossy,
• fabric,
• plasterboard ceiling structures.

For each type of ceiling, there are certain repair rules that should be followed in order to restore the surface as quickly and efficiently as possible.

Tensioners

To eliminate traces of a flood on a suspended ceiling, operate according to the following algorithm:

1. Remove the brackets that secure the tension fabric from the angle as close as possible to the leak site.
2. Folding back the canvas, drain the accumulated water.
3. Clean the softened layers of plaster on the rough concrete base (work must be carried out as carefully as possible so as not to damage the tension fabric)
4. The cleaned surface is dried with a construction hairdryer, after which the tension fabric is fixed with staples in its original place.

It is strictly forbidden to pierce suspended ceilings in order to drain accumulated water. Under pressure, a small puncture expands and turns into a huge hole that cannot be repaired.

Plasterboard

It’s easy to restore the original appearance of a plasterboard ceiling, the main thing is follow a clear sequence of actions:

• using a sharp knife or screwdriver, pierce the drywall sheet and drain the accumulated water;
• by expanding the puncture site, determine the degree of damage;
• if the water leak did not have time to significantly deform the ceiling covering (the drywall did not swell, a loud knock is heard when tapped), then after drying the leak, the hole is covered with a layer of plaster, primed and whitewashed again.

Glossy

The easiest way to clean glossy surfaces from yellow stains after a flood is. After the water has been drained from the interceiling space, the glossy film is mounted in its original place, and traces of the flood are wiped with a sponge soaked in an alcohol solution (2 tablespoons of alcohol per liter of water is enough).

When cleaning glossy tension sheets, do not use hard brushes or sponges that contain chlorine, alkali or acid. The result of such cleaning will be a completely damaged surface.

Fabric

Minor signs of flooding on the fabric surface of the ceiling wet cleaning using soda ash will help remove.

It is enough to dilute the soda to a thick paste with clean water and apply the resulting product to the yellow traces of the flood.

After the soda paste has dried, it is washed off with warm water, and the fabric ceiling is wiped dry soft rags.

If after cleaning the traces of the flood have not disappeared, the entire surface of the tension fabric covering is painted with water-dispersion paint.

Adviсe

A few secrets of experienced craftsmen will help carry out work to eliminate yellow stains on the ceiling quickly and efficiently:

1. Before you begin any work to eliminate signs of flooding, you must make sure that the electricity supply to the meter is turned off.
2. Before you begin to remove traces of the flood, you must carefully tap the entire surface of the ceiling with a rubber hammer. This will help diagnose hidden places where whitewash is peeling off from the rough surface.
3. It is necessary to clean the ceiling after a flood as quickly as possible. While the paint and plaster are wet, they can be easily removed in single strips. Dried traces of a flood are much more difficult to clean efficiently.
4. Instead of industrial chemicals, yellow stains can be whitened with a homemade solution. To do this, mix one part of concentrated citric acid and two parts of crushed chalk. Glycerin is added to the resulting mixture (it should turn out to be a thick paste).The resulting composition is applied to the yellow stains and left for sixty minutes, after which the stains are washed off with clean water.
