Magnetic effect paint - the know-how in the paint industry

Everyone knows how problematic it is to hang a photograph on a load-bearing wall. Of course, you can glue it with tape, but in this case there is no question of any aesthetics. This can be done carefully only if there is a frame and a puncher that needs to drill a hole, fix a dowel-nail in it, onto which a frame with a photograph will later be fixed. And it would be convenient to just press the photo with a magnet. As it turned out, this is entirely possible. For this purpose, magnetic inks are used, the properties and features of which will be discussed today.

Magnetic paint: what is it

Such paints were created relatively recently. In composition, they do not differ from any water-based coating. The only difference is the smallest metal particles added to it. As a result, after painting, the surface easily holds the magnet. It doesn’t matter whether after (for example) the white magnetic paint is coated with a layer of a different color or if wallpaper will be glued on it - the ability to hold the magnet from this will not go anywhere.

Why use magnetic paint: applications

Most often, such a coating is used in the manufacture of children's repairs. After all, children, adolescents like to hang various posters on the walls, which with the help of magnets is much easier to do. Such a coating can be applied to any surface, be it concrete, plywood, chipboard, OSB or gypsum plaster. It is convenient to use in offices, kindergartens. At workplaces, with the help of such paint, you can hang up schedules and schemes that will change as they move into the category of irrelevant, and in kindergartens, children have the opportunity not only to play additional games, but also to develop fine motor skills of their fingers.

Magnetic coating is useful not only for children but also for adults:

Helpful information! In addition to all the positive qualities inherent in such a material, magnetic paint is also able to damp electromagnetic radiation from working household appliances, which is important if a small child lives in the house, and even more so an infant.

Magnetic paints: features, technical and operational characteristics

Such a finishing material has the same technical characteristics as any water-based coating. With regard to operational features, among them can be noted:

  • lack of an unpleasant smell that allows their use in preschool and medical institutions,
  • compliance with all fire safety standards,
  • this material is environmentally friendly, it has no harmful effects on the human body, like pets,
  • guaranteed increased adhesion to any surface on which magnetic paint will be applied.

Consider the materials of the most famous manufacturers offering products on the Russian market.

Magnetic paint "Tikkurila Magnetic" ("Tikkurila Magnetic")

Water-borne paint for concrete, wood, plywood. Approximate consumption - about 1 l / 1.5 m² under the condition of three-layer application. There are several different shades in the Tikkurila line of magnetic inks, however, if a coating is applied that will then be covered with a topcoat of ordinary ink, a neutral white color is the ideal solution. Consider some of the parameters of Tikkurila Magnetic.

In the absence of an unpleasant odor during the coating process, its long drying time will not cause any inconvenience. After 24 hours, you can apply the finish coating in any color scheme. Paint for the decorative layer should also be water-based.

Criteria for choosing a similar finishing material

When choosing a magnetic paint, you should pay attention to the volume of packaging. Only at first glance it seems that it does not matter. If the manufacturer offers the coating only in containers of 0.5 l, and you need to cover 4 walls in the nursery, the overpayment will be significant than when buying a five-liter can.

Drying time can also play a role. For example, there are brands of paints that can be coated in 5-6 hours, which is undoubtedly a big plus.

After applying the magnetic layer, you can paint the walls in any color or leave white

Magnetic and marker paint: application features

Marker paint allows you to apply, and then easy to erase, drawing with a special marker - marker. This can be compared to drawing with chalk on a blackboard. If such a coating is applied to a metal surface, only marker paint is used for the magnetic board. If the surface is concrete, plastered or wooden, magnetic marker compositions are used. This allows, for example, to place photographs on the board, placing arrows from one to another or sign them, and after that - to freely remove pictures and erase captions.

Such coverage can be used by children for games or adults for work:

Slate effect magnetic inks: what are they used for

Similar compositions have dark shades and are used to provide the ability to draw on the surface with crayons. After applying paint for a magnetic board, the surface becomes as if covered with a layer of dense rubber, which also provides its additional protection. Otherwise, there are no significant differences with the magnetic finishing material. The acquisition of such material is also not difficult. You can buy magnetic slate paint for walls in any specialized store or through online resources.

In addition to entertainment for children, such paint is used in various cafes or even as a “reminder”:

DIY magnetic paint manufacturing: what is required for this

Of course, magnetic ink stylus has to be bought if necessary. And what about the usual white finishing material? As it turned out, making magnetic paint with your own hands is completely uncomplicated. To do this, you need any acrylic paint, cement and metal dust. Pour 2 tablespoons of cement and metal dust into the container, add 1 cup of paint and mix everything thoroughly. That's the whole cooking process.

The nuances of applying magnetic paint to the wall

Preparation for painting is not difficult. First, we clean the surface of peeling paint or old coatings. This should be done extremely carefully. If there is glossy paint on the surface, sandpaper should pass through to make it matte. After washing the surface by any means, so that it does not leave dust, grease or similar impurities. If the surface is uneven, it makes sense to correct the potholes and cracks with a finishing putty. After complete drying, apply magnetic paint in 3 layers and allow to dry completely. Now it's up to the small thing - the topcoat.

Before applying magnetic slate paint, the wall should be carefully prepared.

What is magnetic paint

At its core, this is the usual paint substance of one color or another. The composition of this mixture contains small inclusions of metal, providing a magnetic effect. The coloring composition covers the wall surface and furnishings. It forms a magnetized surface that attracts magnets. This is a very convenient solution for residential and office space, kindergarten and school class. Above the magnetic paint layer, you can add the finish layer of the desired color or paste over it with wallpaper. In this case, the magnetic characteristics do not disappear.

Advantages and disadvantages

Coloring compositions with magnetic properties have undoubted advantages:

  • do not contain harmful impurities,
  • flammability safe
  • perfectly fixed on various surface textures,
  • devoid of pronounced odors,
  • economical to use.
  • able to shield unwanted electromagnetic radiation from consumer electronics (PCs, televisions, microwave ovens, etc.).

Along with this, these paints have specific disadvantages. The inclusion of metallic additives in the coloring mixture limits the variation in color shades of the product. It is produced in a limited number of options:

However, this is not difficult to correct by applying surface painting with standard acrylic paint of the desired color. In this case, it should not be applied in several layers, so as not to neutralize the magnetic effect.

Scope of magnetic paint

Magnetic coloring composition is applicable on almost any basis:

Often this paint is used in children's rooms. It will be convenient to hang visual aids, alphabets, drawings on the surface treated with it. In office conditions, such a magnetic layer allows you to comfortably place all kinds of informative material. It can be charts, operational reports, reference information. This data is very easily replaced with new ones, without requiring significant effort and time.

Types of Magnetic Effect Inks

Today, the building materials market offers a rich assortment of magnetic inks. Everyone can find the most suitable option. As an example, consider several popular brands of this paint.
Tikkurila Magnetic - a slate composition from a Finnish manufacturer that provides the texture of a wooden board. This composition is often used in schools and kindergartens. It is applied to the walls to create an alternative to the classic chalkboard. It’s also convenient to update old blackboards, giving them additional magnetic properties.
The generally recognized plus of this brand is its excellent wear resistance. The manufacturer guarantees that the magnetic layer is not erased after 5 thousand brushings. In addition, the paint is excellent and washable without loss.
It should be remembered that it is better to apply the paint in more than one coat. In addition, the composition should be diluted to reduce material consumption. It is better to apply the solution with a short-nap roller so as not to waste too much paint.
Relatively new to the CIS countries is the brand Magpaint. He has already managed to collect a lot of positive reviews, including from professional finishers. One liter of composition is enough to cover two square meters. At the same time, it is recommended to cover in 3 layers in order to obtain a high-quality painted surface.
Experts call the advantage of Magpaint the ability to use this paint even on surfaces of the most complex profiles, including:

The budget brand Siberia is a slate coloring composition with the effect of metallic gloss Siberia. Having processed this or that surface with this paint, you will get a surface on which it is convenient to draw not only with ordinary chalk, but also with slate.
But the main advantage of this composition is the greatest resistance of all considered, the paint can withstand up to 10 thousand brushes. In addition, the mixture contains a protective ingredient that prevents the growth of the fungus in a humid atmosphere. For this reason, Siberia is suitable even for relatively damp rooms (bathroom, kitchen), as well as for external walls.

Conclusion

The choice of brand or method of manufacturing magnetic paint is a matter of taste and depends on the specific situation. But in any case, follow the rules of safe painting work with paints and varnishes, apply paint to cleaned and dry surfaces. By clearly following the recommendations, you can create a high-quality and smooth magnetic layer.

Disadvantages

The metallic particles included in the paint give the paint a very limited color palette. Enamel is available in gray, brown, black, blue and green. But this problem is easily solved by painting with ordinary acrylic paint of any color.

You need to paint on top in only one layer so that the magnetization does not weaken.

Training

A wall, or other base, needs to be well cleaned of dirt, dust, grease, oils, mold, fungus. Old paint or other paintwork should be removed with a solvent, sandpaper, or grinder. The surface is well washed with detergent, completely dried. After cleaning, it is necessary to give the surface a uniform, even appearance with putty and grinding work. Further, a deep penetration primer is applied to the base, which will increase the adhesion of the future coating and reduce paint consumption by 1m2. Penetrating soil is applied in 2-3 layers, each subsequent only after the previous one has completely dried. It is the last layer that is painted.

After opening the can with the mixture, it is worth thoroughly mixing its contents to obtain a uniform consistency, otherwise, peeling of the coating is possible in the future. For stirring use an electric drill with a nozzle.

Application

For maximum magnetic effect, the paint should be applied in several layers, at least 2, and preferably 3-4. For application to the wall, a paint roller with a pile length of 6-9 cm is used. Next, the entire mixture is spread over the surface with a spatula until it becomes even and smooth.

If you need to paint not the entire wall, but only a part of it, then the edges of the area should be limited to masking tape. A new layer is applied after drying the previous (

4 h) and only on a completely smooth smooth coating, which is achieved by movements of the spatula on the applied enamel of each layer.

On 3 layers of 1 sq. m. coverage will need half a liter of material.

After processing all the layers, a day should pass for the most complete adhesion of the paint to the wall. Further, the finishing application of paint with a marker or graphite effect is done.

Popular brands

Among the most popular and high-quality brands, Tikkurila brands with the name Magnetic paint, the Russian-made Siberia brand and the Dutch company Magpaint stand out.
