The Best Anti Mold Paint: Our Picks

Guide: Questions you should ask yourself before buying anti-mould paint

How does anti-mould paint work?

Anti-mould paint is a special wall paint that is applied to the wall to prevent mould. Thanks to its moisture-regulating properties, it prevents the formation and spread of mould. An optimal anti-mould paint for indoor use keeps mould out of all rooms, but only with an ideal indoor climate. An ideal indoor climate can be achieved by regulating the air humidity.

If the humidity in a room is far too high, then even anti-mould paint will not help.

This means that you can only use anti-mould paint prophylactically, because in addition to your anti-mould paint, sufficient heating and ventilation is also necessary.

Before painting, you must remove the mould on the walls, because anti-mould paint cannot be used to remove an already existing mould infestation.

On which surfaces/materials can I apply anti-mould paint?

Anti-mould paint can usually be applied to any surface that is suitable for normal interior paint. You can also use it on wallpaper and plaster. There are also special anti-mould paints for wood and for fighting mould in unheated rooms, such as your garage or basement. If in doubt, you can always look at the packaging and find out on which surfaces and for which areas the respective product can be used. In most cases, it can only be used indoors.

Is anti-mould paint harmful to health?

Yes, the solvents in anti-mould paints can be harmful to health, especially in the first few days after application. The solvents in anti-mould paint are used to regulate the consistency and are mostly composed of volatile organic compounds.

Be especially careful in the first few days after application, because the anti-mould paint outgasses the VOCs ("volatile organic compounds") during this time, which get into the air you breathe.

Negative effects can also include nausea and headaches. Furthermore, your mucous membranes can also become irritated. You should be especially careful in bedrooms and children's rooms, because the solvent of the anti-mould paint will certainly have harmful effects on your health. When buying anti-mould paint, we recommend that you make sure it is solvent-free.

What alternatives are there to anti-mould paint?

Besides anti-mould paint, there are other alternatives that have similar functions. Each alternative has different advantages and disadvantages. In the following section, we will give you a brief overview of the alternatives to anti-mould paint. Possible alternatives are:

  • Anti-mould primer
  • Silicate paint against mould

We have prepared a small table with the respective advantages and disadvantages of the two alternatives to anti-mould paint.

Type Advantages Disadvantages
Anti-mould primer Suitable for ceilings Need an additional wall paint
Silicate paint against mould Healthy and environmentally friendly Not optimally suitable against mould

Buying criteria: You can use these factors to compare and evaluate anti-mould paints

In the following, we will show you which aspects you can use to decide between the many anti-mould paints. The criteria you can use to compare different anti-mould paints include:

In the following paragraphs, we will explain to you what is important in each of the criteria.

Anti-mould paint without solvent

Anti-mould paint with solvent is used to control the consistency of ceiling and wall paint, but it is composed of volatile organic compounds (VOCs for short). Especially in the beginning, after painting, the VOCs outgas and become airborne. Once in the air, these compounds are inhaled and can have harmful consequences for human health. Therefore, you should not buy anti-mould paint that contains solvents, especially for bedrooms and living rooms.

Anti-mould paint without biocides and fungicides

An important purchase criterion is whether the anti-mould paint contains biocides and fungicides. Mostly, anti-mould paints contain fungicidal preservatives. Active ingredients such as zinc pyrithione, octylisothiazolinone and iodopropynyl butylcarbamate are often used. Anti-mould paint with biocides and fungicides is optimally effective against mould, but continuously releases its active substances into the environment.

Did you know that these substances are almost always harmful toxins that can cause headaches, irritating coughs and burning eyes? This is because these substances are not only distributed on and in the wall, but they also reach the indoor air and thus enter our respiratory tract.

Therefore, we advise you not to use this anti-mould paint in the bedroom, bathroom and other living spaces.

Especially in the children's room you should not use it to protect your children from the bad active substances.

In addition, this paint loses its effect over time due to the continuous emission of the preservatives it contains. Therefore, it does not offer you permanent protection against mould. Another disadvantage of anti-mould paint with biocides and fungicides is that it is harmful to the environment because many toxic fumes are emitted during its production. Furthermore, when using this paint in the garden, you must make sure that pets, birds and beneficial insects are out of reach.

Durability

Durability is another criterion you should consider when buying your anti-mould paint. To ensure that the paint remains effective over a long period of time, it is important to keep the container tightly closed. Whether you use your anti-mould paint on wood or put it on a wall, a good paint will prevent mould from forming again for a long time.

Paint

Another important criterion is the colour, because anti-mould paints are now available in different shades.

Benefit

The benefit is another purchase criterion that you should consider. The best quality anti-mould paint destroys the mould in the shortest time and ensures that it does not come back. This prevents bad consequences for your health. Furthermore, a good anti-mould paint is easy to apply and can be easily painted over all walls.

Facts worth knowing about anti-mould paint

What do I have to consider when painting with anti-mould paint?

First you have to determine the amount you need. Depending on the opacity of the anti-mould paint, it can cover approximately 3.5 to 7 m² per litre . Painting with anti-mould paint is the same as with any other wall paint. Remove old paint residues from the wall and clear the painting surface. You should fill in holes before painting and remove all possible obstacles. We recommend masking edges and transitions with masking tape. Stir the paint well before applying it. Then you can apply it to the wall with a roller, brush or paint spray system.

Depending on where you want to apply the anti-mould paint, you should use the best applicator for the selected area.

It is also important to apply the paint evenly, it should be neither too thin nor too thick. A tip from our editorial team is to illuminate the wall to be painted well, so that you can recognise any irregularities when painting. Several coats are usually necessary, depending on the opacity of the paint and the surface on which it is painted. To give you an idea of the various steps that need to be taken when removing mould, we have prepared a video for you.

Are home remedies against mould a good idea?

No, home remedies against mould are not a good idea, because at first the mould may stand still, but it feeds on the home remedies and comes back stronger and bigger.

Tips for avoiding mould

To avoid mould, you should ventilate often and heat properly. Stuffy and cold air provides an optimal breeding ground for mould spores, so you should make sure that the rooms have enough fresh air and warmth. Indoor rooms where you are hardly ever present should not cool down. A room temperature of 19 to 21 °C in all living spaces would be ideal. In general, the room temperature should never be below 16 °C. For this purpose, we have compiled a table with the different rooms and the corresponding optimal room temperature.

Room Temperature in °C
Children's room 23°C
Bedroom 18°C
Kitchen 18 to 19°C
Bathroom over 23°C
Living room 21 to 23°C

Ventilation is very important for effective mould prevention; you should air two to four times a day. In the kitchen and bathroom, it pays to ventilate more often because the humidity is usually very high there.

Did you know that it is much more effective to ventilate the room with a push instead of tilting the window? If your window is open all the time, the difference between the outside and inside temperature makes it difficult to exchange air, especially in winter. Instead, the room temperature cools down and the energy costs rise.

The most effective way to ventilate is to create a draught that brings fresh air into the room and draws moisture out. Another tip is to place cupboards and other furniture in cold rooms at least 10 cm away from the wall. This is the only way to ensure sufficient air circulation. We recommend turning off the heating when airing out to save energy. The humidity in the room should never exceed 60 percent. You can use a hygrometer to check the humidity. We have found an interesting video about this, which reports on mould infestation in flats. https://www.youtube.com/watch?v=ir-SoqynhWc
