How to treat a wall with moisture due to condensation

Moisture in ceilings, floors, walls or window boxes is a recurrent problem in any construction. You can identify it by the formation of stains, bad odors, bulging, weakening, saltpetre, etc.

Rising damp is manifested by dark stains on floors and walls, white efflorescence (caused by saline substances in the water that rises, evaporates and crystallizes), buckled paint chips or even the degradation of the affected wall.

In the first case it can occur because there is more water vapor than the house can withstand, combined with poor ventilation. The vapor turns into liquid water, which permeates the walls and causes mold.

The second case is caused by poor thermal insulation in the walls near the facades, pillars or window frames. Cold condensation is similar to what happens inside cars when the temperature drops and moisture condenses on cold windows.

How to eliminate humidity from lower floors?

For the interior of the floor of a first floor the ideal is to use a porcelain floor or pavement. This type of floor has a moisture absorption level of less than 3%. Likewise, to apply it, you should use porcelain tile adhesive cement that also has anti-humidity properties.

What happens if you sleep in a damp room?

A damp room is perfect for dust mites and mold. Sleeping in a room with mold can be dangerous, as they produce spores that can cause allergic symptoms and respiratory problems: nasal congestion, secretion, sneezing, itchy eyes, bronchitis…

What happens when there is high humidity in a house?

Moisture due to condensation: causes and solutions

Everyday activities such as cooking, taking a shower, turning the heating up too high or drying clothes indoors cause the air to retain the moisture released and, when it comes into contact with a colder surface, it condenses in the form of water droplets.

Homemade Moisture Insulator

Moisture in walls and ceilings is a very common problem in homes and, in addition to being unsightly, can be a real health problem because they favor the appearance of fungi and bacteria. That is why it is so important to treat them, although not all are the same and you have to know how to do it. In this post we are going to see how to fix them.

They are the most common. They appear due to high environmental humidity, which causes an accumulation of water droplets until moisture is generated. This leads to mold and gradually deteriorates the materials. It is also possible that it causes bad odor. This type of humidity is easy to prevent and also to solve. If the room has windows, just opening them is enough, or placing a mechanical ventilation.

They appear at a certain point, usually on the ceiling, and are easily identified by a change in color or because the paint is softening. The cause is usually due to a broken pipe and the continuous dripping causes the water to gradually seep into the ceiling. The solution is to repair the pipe and then paint with waterproofing paint for dampness.

How does humidity affect people?

If you have dampness, you may have symptoms such as: heaviness of the head and body, particularly when you get up in the morning, limbs with little strength, appearance of more eye discharge (if you also have heat, the discharge is yellow), possible diarrhea, nausea or vomiting, lack of appetite, constant fatigue and lack of energy for …

How to avoid humidity in a low floor?

Use chemical barriers.

This consists of impregnating the inside of the wall with repellent products (generally siliconized compounds) that prevent water from rising and that are permeable to vapor to eliminate the risk of condensation.

How to treat damp walls before painting?

Hydrogen peroxide: we apply a solution of water and hydrogen peroxide on the wall with a cloth until the remains of mildew are eliminated. Before painting, we wait until the wall is completely dry.

Devices to remove moisture due to condensation

Water exhaustion is the most widespread effect when serious structural problems occur, since this pathology (continuous dilatation-contraction), causes cracks in the ceramic pieces, which can end up weakening the base of the house.

Inside the hole, between 12 and 14 mm, a liquid is injected that reacts with different chemical elements of the wall, to generate an impermeable plastic barrier that prevents humidity from continuing to rise.

If the conditions of situation of the wall with respect to the ground level (only above the level) and the type of material (solid ceramic, geros or hollow brick with gel injection) allow the injection with efficiency, it is always possible to adjust the performance to the minimum intervention.

The materials used for injection are always from different known manufacturers and no custom-made products are manufactured for any brand. In any case they are packaged with the logo of each company.

In general some of the prices of these applications that are sent to us in the consultations, are not justifiable in relation to the real work of these treatments and the costs of the materials used.

What happens if you breathe humidity?

Excess ambient humidity increases the possibility of contracting respiratory diseases such as asthma, sinusitis, and lung infections such as bronchitis.

Why does my bed feel damp?

Windows: these elements are a great indicator of the humidity level. … Touch the bed sheets: if they are damp, your room is damp, and, most likely, so is the rest of your house. Some of the causes for this to happen are water leaks and if your house is not well insulated.

How does humidity affect your body’s resistance?

When the skin is moist (not wet) the resistance drops to 1500 ohms. Moisture increases the conductivity of the skin. This allows the current to go not only over the surface, but through the areas of the body with the highest water content.

How to insulate a damp wall

Moisture can be a real nuisance. It causes damage to properties and can even be harmful to your health. If you want to eliminate dampness once and for all, the best thing to do is to look for professional treatments. In this price guide we tell you how much it costs to fix damp from different procedures.

Keep in mind that moisture can cause different types of damage (mold on the walls, leaks, bad odor, chipping paint, etc.), and not all have the same solution. Therefore, depending on the circumstances or needs, the cost of the service may vary.

There are three main types of humidity: damp due to seepage, condensation (due to poor insulation or poor ventilation) and rising damp (moisture from the subfloor rises through the walls).

While seepage damp can be solved by detecting the source and improving the waterproofing, and condensation damp can be reduced by optimizing ventilation, in the case of rising damp different procedures can be followed: waterproof sheets can be inserted in the walls, chemical barriers can be used, electro-osmosis can be tried or hygroconverters can be installed.
