Shopping guide

Avoiding moisture on the walls or delaying its appearance is important, not only aesthetically, but it is crucial to prevent respiratory diseases, for this reason, we have prepared this guide to buy the best anti-humidity paint, with the aim of making a good investment in a product that really solves the problem.


Guy

When making a comparison of anti-humidity paints it is good to first define what is the real need that you have at home. Many times we buy the wrong product because we confuse humidity with mold, which is why it is worth differentiating these concepts. We can say that humidity is a first step, while mold is a fungus that arises when we do not solve the cause of humidity.

There are paints that only prevent moisture, while others have additives that fight the living organisms that make up mold. This can give you an idea of ​​how much the product costs, but you can get a good, inexpensive paint that is moisture-wicking and anti-mold at the same time, providing added protection.

Another classification that we can make is between anti-humidity paints for interiors and exteriors. The former, as its name implies, are indicated for the walls of the kitchen, bathroom and other rooms within the house that have constant contact with water. These are breathable, that is, they allow the correct circulation of air to avoid the accumulation of steam, thus keeping the surface dry.

On the other hand, the anti-humidity paints for exteriors are usually resistant not only to water, but also to the rays of the sun, therefore, they can be outdoors during all seasons of the year. In addition, they are usually able to resist impacts and scratches for greater durability. Many of these paints are also anti-mold, although these can be a bit more expensive.

Technology

The paint technology can vary from one model to another and this influences the effectiveness of the product, but also the practicality when applying it, for this reason, it is good to pay attention to the data that have to do with the properties.

Although they seem contradictory to the naked eye, the most important properties in a moisture-wicking paint are breathability and impermeability. On the one hand, it is important that it allows air to circulate, as this can prevent the accumulation of steam. However, it must also be able to prevent the penetration of water in a liquid state, thus protecting the wall.

Many anti-humidity paints are made of acrylic copolymers, so they can be diluted in water, but once they dry they are waterproof. Some also have waterproofing technology, which means that they do not allow water to pass through by capillarity and at the same time are breathable. In addition, they can be applied on brick, plaster and concrete for greater versatility.

On the other hand, there are anti-humidity paints that have thixotropic technology, which allows the mixture to be kept much more stable, so that the paint does not drip from the roller or brush onto the ground. In this way, it is not only easier to apply, but you will not have to do a lot of cleaning work when you finish the task.


Quantity and color

We can say that most of the anti-humidity paints are white, this is actually a commercial decision of the manufacturers, since it is the best-selling color. However, some brands have long lists of colors to select the most appropriate to your tastes and the decoration needs of each space. In this sense, it is good to know that sober tones predominate, such as ocher and very striking and intense colors are usually scarce.

Regarding the quantity, it depends to a great extent on the covering capacity of the paint and the skill of the user when applying it, but we can say that generally 1 liter yields for a wall of 10 to 12 m² and can even reach 15 m². In this sense, it is important to calculate the necessary amount taking into account the entire wall, not just the area that has the moisture stains, since it is important to protect the entire wall to prevent the reappearance of the problem.

It is always good that on and not that it is missing. In general, cans with more quantity have a better price, but it is advisable not to buy too much, since anti-humidity paint has a limited shelf life of 1 to 2 years after opening the container.

Frequently asked questions

Q1: How to use the anti-humidity paint?

Anti-humidity paint is used like any other, so applying it is a fairly simple job, however, certain previous steps must be taken into account. First, you must stop the cause of humidity at its roots, which can be condensation from a lack of ventilation in the space or a leak caused by a damaged pipe.

Once you have solved the main problem, it is time to prepare the surface. In this case, it is necessary to remove the old paint that has moisture with a spatula, and then pass a fine sandpaper, in order to make the wall as smooth as possible, if necessary, you can use repair plaster, in this In this case, you should let it dry for at least 2 hours. You can then apply a coat of universal primer that you have at home with a brush and let it dry completely.

The final step is to apply the anti-humidity paint, for which you can use a roller. Experts recommend covering the entire wall with this special paint and not just the visibly affected part, this allows the effect to be more durable.


Q2: How to prepare the anti-humidity paint?

As you may have already observed, there are paints specially made to avoid humidity, this is thanks to the fact that they have a special composition that makes them more permeable, therefore, they allow good air circulation, thus avoiding the accumulation of vapor. To prepare it, you just have to mix it previously so that the components are well combined.

However, it is also possible to improve the properties of any plastic paint with an anti-mold additive, for this, you must mix the paint with the biocidal substance until a homogeneous mixture is obtained and then apply the paint on the dry, smooth and clean surface.

Q3: How to remove the anti-humidity paint?

Fortunately, anti-humidity paint works in the same way as conventional ones, therefore, to remove it you must first remove the remains with a spatula, and then pass a fine sandpaper over the entire area.

If the paint is very deteriorated, it is good to remove it completely if you want to repaint the wall, but if it has been kept in good condition it is not necessary to make a great effort, since the new paint will adhere easily just by cleaning the surface.

Q4: How to make homemade anti-humidity paint?

The anti-humidity paint itself is an industrial product that has different components and is manufactured with certain technologies, therefore, it is unlikely that you can do it at home.

However, what you can do is a homemade mixture to clean the wall before applying the paint, for this you just have to mix water with baking soda and spray the wall, leave it on for a few minutes and then clean with tap water. If necessary, you can repeat the procedure for greater effectiveness.

Q5: Is the anti-humidity paint also anti-mold?

Although many products have both properties, the truth is that an anti-humidity paint is not necessarily anti-mold, for this reason, it is of great importance that you thoroughly review the characteristics of each model. Also, it is worth noting at this point the importance of defining the real need, that is, that you must verify if the wall really has mold or is it only moisture.

Anti-mold paints have additives that kill living organisms that stick to the walls, while anti-humidity paints only prevent condensation and vapor build-up, but do not have biocides.

Q6: Can I wash the anti-humidity paint?

This is a question that many of us have asked ourselves at some time, especially for the fear that it will be counterproductive to wet the wall once we have fought against the humidity and applied the special paint. However, most of today’s moisture-wicking paints are easy to clean with a damp cloth.

In addition, they are precisely made to resist water, so they are easily washable. Some experts recommend regularly washing the walls where there is a risk of mold accumulation, in order to avoid diseases related to fungi and bacteria.


Q7: How to clean anti-humidity paint residue?

When you finish painting the walls you may see some dry drops on the floor, but this is not a big problem, you should only use a universal stripper and a sweeping brush. Apply the product in the places where the paint remains and let it act for about 10 minutes, then you can remove it with the brush, to finally clean it with a mop.
