Wood based paint for wood for outdoor use. Types of water-based facade paint. Silicone paints: advantages and disadvantages.

A widespread and sought-after material for outdoor work is facade water-based paint. She gained popularity due to its low price, ease of application and good performance  - strength, non-toxicity.

Composition and properties of facade water-based paint

A water emulsion is a water-based paint. The composition is a suspension: pigments are present in the water (for painting the surface) and binders (for adhesion, adhesion to the surface). Substances are not dissolved in water, but are present in it as a suspension.   After surface treatment, water evaporates and the pigment remains on the surface  in the form of a thin film layer.

Inner painting Type 2 Cover

Uses: Used to decorate and protect doors, windows, grills, baseboards and wooden objects. Features: Excellent adhesion and flexibility. The paint is made from water-soluble acrylic vinyl resins for indoor use. Matte finish, good covering ability.

Ideal for protecting and decorating your home and office, concrete surfaces, plaster, plaster, asbestos cement, ceilings and doors. This stage may be the most interesting, but overwhelming due to the number of colors to choose from. To make the right decision, you must consider the light, both natural and artificial, of the environment that you will paint. Paint will reflect light in different ways. Therefore, the most appropriate is that you try to use the colors in the wall, depending on the type of light that gives during the day.

In addition to the main ingredients (astringent, pigment, water)   different paints may include the following additives:

  • antifreeze agents that prevent freezing: used in the manufacture of paints for external use;
  • antiseptics that prevent the growth of fungus and mold;
  • defoamers (to reduce foaming);
  • thickeners, plasticizers and other components that improve operational properties.

Differences in facade paint from similar material for interior use:

It is important to note that the brighter the paint, the greater the reflection of light on it. In addition, it will show you more flaws on the surface where it is applied. Also consider color classification. That is, if they belong to a warm, cold or neutral harmony. The former have more red; seconds, blue, while neutrals have more yellow. In addition to this combination, colors have a greater or lesser share of black and white. According to them, the paleness or darkness of the tone is determined.

Remember that the decision to choose a paint color goes further. For this reason, consider the range of colors that you will apply to your entire set. Get well and follow your instinct. Water-based paints contain water as a solvent, so they are safe for health. Within our advantages, we can also assume that they dry out in a short time. Thus, the second hand can be completed after about 6 hours. In addition, they are ideal for indoor use, as you can use the medium a few hours after your use.

  • resistance to low temperatures;
  • water resistance;
  • resistance to ultraviolet;
  • high resistance to pollution.

Acrylic based water based paints are best suited to these requirements.

Pros and cons of water-based paint for facades

Advantages:

  1. Ecological purity, non-toxicity. The composition of the material does not include solvents and other harmful substances.
  2. No smell when stained.
  3. High vapor permeability (painted surface “breathes”).
  4. Incombustibility.
  5. Ease of application.
  6. Low consumption (in comparison with other paints).
  7. Durability: high-quality coating lasts up to five years.

Application of facade paint

Recommended   for processing any surfaces except metal.  Water oxidizes the metal, contributes to the formation of rust. But sometimes manufacturers add corrosion inhibitors to the initial composition, this makes paints suitable for painting metal. Such a water-based emulsion can even paint the roof.

Meanwhile, solvents smell more, and you need to dilute the solvent. In addition, they better cover the surface, harder and more stable. You can also find it on rust, which is inaccessible to water. They are weather resistant, although they do not withstand alkalinity. Therefore, if applied to surfaces such as concrete, plaster and brick, it will be necessary to neutralize and then seal the surface. Currently, the technology is developed, and we have synthetic water-based enamels that have the same properties as classic solvents, but now they are more environmentally friendly.

Most emulsions are suitable for staining:

  • any concrete;
  • for finishing the plaster wall, basement;
  • brick and stone walls;
  • previously painted surfaces (except for walls covered with glossy paints);
  • you can paint the walls of timber, logs lined with clapboard, as well as other wooden surfaces: doors, fence, windows, garden furniture.

Each surface has its own preparation features:

Indeed, there are different manufacturers. As the name implies, they are suitable for cleaning stains without removing paint, so they are ideal for use in transit areas, as well as for children's rooms or game items. To remove dust, you need a vacuum or dust. Then, with a cloth or a damp sponge in warm water, go through the wall from top to bottom and cook.

If the facade to be painted is concrete, plaster or brick, we recommend applying enamel to the water outside, previously prepared with a primer. If it is metallic, like a grate, you need to use synthetic water-based glazes. The main difference between the varnish and the stain is that the first creates a film on the surface that needs to be applied, while the stain penetrates the wood and protects it from the inside. Keep in mind that all outdoor products are more resistant to the effects of meteorological and climatic agents.

  1. The plastered and putty wall must be assessed for durability before starting work. Peel off loose areas and apply a leveling coating again.
  2. It is recommended to remove old paint to the maximum. A durable-looking coating may begin to peel off when painting again (especially when using a roller).
  3. Before painting, it is necessary to prime the wall. The type of soil depends on the surface material.
  4. Wooden walls are recommended to be treated with antiseptic compounds.

The emulsion consumption for wood is slightly higher than for other surfaces.

In addition, they usually have ultraviolet filters to best preserve wood exposed to sunlight. It depends on the environment. Therefore, the recommendation for each space: Bathrooms: Given the large amount of humidity, glazes with a low brightness should be used, since they are more washable. Humidity, on the other hand, promotes the growth of fungi. You can usually find antifungal paints that will reduce the likelihood of their spread. Kitchens: Water-based glazes with low brightness are recommended for easy washing and to support certain abrasive products.

Specifications and Requirements

  1. The specific gravity is about 1.35 kg per liter.
  2. Adhesion (adhesion to the base) - 2 megapascals.
  3. Full drying time - up to 11 hours. Depends on air temperature and material grade.
  4. Operating temperature mode. Aqueous emulsion paints for outdoor use is not recommended for use at subzero temperatures.
  5. Paint consumption: 120 to 150 grams per square meter.
  6. In accordance with GOST standard 28196-89, the coating must have frost resistance of at least five cycles.

Application methods, equipment and tools

  1. When calculating the material, consider that the manufacturer indicates the flow rate for ideal conditions:  flat surface, high-tech artist, etc. It is recommended to buy paint with a margin.
  2. The color of the surface matters. If you repaint the wall in a different color, you will need several layers of paint. If the tone of the previous coating is enough, one or two layers are enough.
  3. It is necessary to store the paint in a dark room at a plus temperature from +5 to +30 (more precisely - in the recommendations for a particular brand), in tightly closed packaging. Average shelf life is four years.  If temperature requirements are violated, the material may begin to delaminate.
  4. Before use, the paint must be thoroughly mixed.  If desired, mix the material using a construction mixer. It is better to breed the pigment immediately in its entirety, because second time to choose exactly the same shade will be difficult.
  5. The tool (rollers, brushes, brushes) at the end of work must be washed immediately. If it is supposed to resume work after some time (after two hours, every other day), the tool is left soaked in water.

Major manufacturers

  1. Tikkurila (Finland).  The main packaging is 2.7 liters, 9 and 18. The price depends on the packaging and brand. Examples:

    • Yki (there are several subspecies) - about 1.2 thousand 2.7; about 4 - 9.

    Approximate consumption: up to 6 meters - 1 liter.

    This reduces grip and, of course, improves cleaning. Children's rooms or delicate health: the use of odorless paint is beneficial for those who cannot withstand intense odors or respiratory problems. It is advisable to use paints of easy cleaning, especially for children's rooms.

    It is advisable to re-color the exterior of the house every 2 to 3 years under normal conditions. However, if this is a place with a lot of exposure, this period should be shorter. Keep in mind that if the paint has been cleaned, this means that repainting is not enough, but preliminary surface preparation is necessary.

Water-based paint is a popular material for internal (painting of the ceiling and walls) and external works (painting of facades). We will introduce you to the features of painting and present a video example for a more detailed acquaintance with the technology so that you can do all the work yourself.

If the tree is new, it is unlikely to be dirty, but it can detect irregularities that must be covered with some kind of wood paste or mastic. Once this substance has dried, it will be enough to get sandpaper more or less thick, depending on the previous smoothness of the surface and the one that it is desirable to achieve. Then the dust is removed with a clean, slightly damp cloth. With the composition described above, the wood is ready for staining, but if you are looking for the best results, you should use 2 substances before painting: firstly, a wood preserver that guarantees long-term health of the material and that it needs to be a dry well for at least 24 hours; and secondly, a universal wood sealant that provides paint adhesion.

Aqueous emulsion ink for internal and external works

For painting surfaces inside buildings and facades of buildings, not only water-based paint is used, but also, but now we’ll talk about water-based paint. High-quality painting of surfaces when performing internal and external works without visible defects is a complex smoky process that requires physical endurance and, of course, knowledge of the painting technology. The quality of water-based paints also affects the final result, so it is important to know where to buy it and how to choose it.

Instead of sealant, an alternative is to apply a first coat of paint. But if so, the picture should be significantly reduced by water. After applying this first coat, fine emery paper should be applied again so that the paint can be applied without clipping. Preparing a wood surface that has already been painted requires a bit more work, as you first need to remove the old paint with a paint remover. This task should be carried out with a brush and hands protected by rubber gloves, as this is a corrosive substance.

Given that non-compliance with the painting technology is the main factor in the appearance of defects, you need to carefully familiarize yourself with the features of the work when painting the ceiling, walls and facade. Naturally, the ceiling is painted first, and then the walls.

Paint the ceiling with water-based paint

You can familiarize yourself with the technology of painting the ceiling in, and now we will consider the features of the work when using a water emulsion.

For the same reason, care should be taken not to touch any equipment. Then remove the old paint with a metal spatula. Before applying paint to wood, it is recommended to apply a layer of preservative and other universal sealant for wood. To clean the surface, after processing with a spatula, skip the fabric soaked in 95 degrees alcohol or a mixture of water and detergent. The surface is then thoroughly washed, if possible, with hot water and a sponge. After this process, it is very possible that the surface has many irregularities, so it is very important to first transfer the coarse sandpaper to smooth it, and then the finest sand sandpaper to get the desired finish.

1. The first stage is the preparation of the ceiling before painting. To renew the painting, make sure that the old paint does not move away from the base, and that there are no bumps or cracks on the surface itself. Otherwise, you have to whitewash from the ceiling. If necessary, align the ceiling. Free the room from furniture, cover the floor with foil.

If gaps form, putty or wood pulp should be used and then sanded again. Then, with regard to the new wood, it is convenient to use substances that ensure the quality of the final finish: a wooden shutter and universal sealant.

Here the party begins, because different mirrors are used, and, of course, different resins or binders, and from here each manufacturer chooses how to combine them to offer their product. The mixture will be given depending on the properties, quality and price that you want to receive. As for the mineral part, to comment that there are different types of minerals and their thicknesses, different thicknesses of the mineral load will be those that are responsible for coating the paint using thicker minerals where a layer with a thickness of more than microns is required and fine-grained minerals where a small layer thickness is required .

2. We cover the ceiling with a primer.

3. Select the paint and prepare the tools. You can buy acrylic, latex and other paints. We used to talk about what happens. As for tools, it can be a roller, airbrush, color, etc. The main thing is that the tools are of high quality, because the quality of painting also depends on this.

On the other hand, if we move to the other end of this, we will most likely carry a large amount of titanium dioxide, dissolve in a good elastomer and have an amazing whitening ability, yes, it will not be suitable for obtaining colors, because titanium dioxide to have such Whitening power, there will come a moment that saturates the mixture and does not allow to exceed a certain tone. Moving on to the part of the resin, this is the one that gives the picture some properties. In short, you can paint the outer paint if it maintains breathability among its properties.

3. Bred ceiling water-based paint. Dilute the paint according to the instructions on the packaging. Typically, the paint is diluted in cold water in a proportion of 10 to 1, after which it is mixed with a power tool. You will need rollers and brushes of different sizes, as well as a tray for paint. A telescopic extension for the roller may come in handy.

If you cover the wall with latex, it will be like a lotus game; it may be that your house has a very well-made structure and does not give you problems, but you run the risk of serious condensation problems in the future, as you will cut the sweating from the walls and, if problems do not appear now, a normal thing that appears in the future, because the latex will not be damaged by condensation, but on the day you put another paint on it, or is of extreme quality or normal condition, it will soon begin to look like mold because of the moisture that keeps the paint in m nowhere to go.

4. Paint the corners. Work on painting the ceiling begins with a thorough painting of the corners with a brush or a small roller. Paint the perimeter of the ceiling by 3-5 centimeters from corners and baseboards.

5. Apply the first layer around the entire perimeter of the ceiling across daylight from the window. Painting the ceiling with water-based paint is carried out with a wide roller. After lowering the roller into the paint, they can apply 3-4 overlap strips. Approximately the paint is enough for 4 strips 3 meters long. Let the first layer dry for at least 4 hours, and more can be done.

So latex forgot, external painting is possible. Facades due to atmospheric factors such as rain, snow, sun and other elements such as dust, pollution, fungi and microorganisms such as mold are one of the most deteriorating parts of buildings. It is highly valued in restoration and restoration work because of its great stability, stability and adhesion to the support. Silicate inks because they are associated with an insoluble chemical process called fossil.

Silicate, without forming a film, gives these paints great permeability to water vapor, turning them into very breathable paints that do not form condensation. Due to their ability to disperse steam, they largely prevent the formation of cracks, bags and chips, keeping the walls dry and intact. It also gives the paint excellent resistance to degradation caused by atmospheric agents and its alkaline characteristics, limits the development of fungi and microorganisms such as verdins, algae, molds, lichens, etc. dirt is less sticky on surfaces with silicate paint, it is easier to clean, because, unlike resin-based paints, they are not thermoplastic and therefore less sticky, and they do not acquire electrostatic charges that contribute to the adhesion of waste.

6. We apply a second layer of water-based paint for the ceiling along daylight using the same technology. That is, the second layer should overlap the first, but you are moving on a different plane. Often two layers are enough, if necessary, additional layers are applied.

Technology for painting walls with water-based paint

Consider using a water emulsion. However, painting the walls with water-based paint practically does not differ from painting the ceiling. Although in this case it is allowed to start from any position, it is best to start from above, so that the drops and drips jumping off the roller do not spoil the painted spots. Aqueous emulsion paint for walls is one of the most popular, economical and environmentally friendly options, for the painting of which the technology discussed above is used.

Painting of facades with water-based paint

For outdoor works, different types of paints are used, which ones we described in. We will deal with the use of facade water-based paint.

Do-it-yourself painting of facade walls with water-based paint using an example of a brick wall:

1. We remove the protruding gaps, remove the old paint and wash the wall.

2. After the wall has dried, we cover it with a deep-penetrating primer designed for plastering and painting facade work. Considering that there are often gaps and seams on the wall, it is better to use not a roller, but a brush. The primer dries for about 4 hours.

3. Prepare the paint, stir it.

4. Paint the facade with a spray gun. Naturally, it will not completely paint the wall, but will create a good uniform coating for subsequent adhesion. So that there are no stains left, we keep the spray gun from the wall no closer than 20 cm. Let the paint dry for about 2 hours.

5. We apply the second layer with a paint wool roller so that the color is saturated and even. For this work, a holder with a long handle is used.

6. We paint seams that are difficult to grasp with a spray gun and a roller. The paint dries and the facade is ready. In this form, it will last up to 5 years and even longer. If necessary, after a few years, repaint the facade. To do this, it is not necessary to remove the old paint, the main thing is that it does not fall off and there is no swelling.

Consumption of water-based paint

Naturally, when choosing a paint for any type of work, consider. Also, before painting a shelf, walls or facade, you need to calculate the consumption of water-based paint. As a rule, the consumption is quite economical - 150 ml per 1 m2 of smooth surface. Having bought a 10 liter bucket of paint, you will cover 70 square meters of the wall with one layer or 35 square meters of the walls with two layers. Often, a 2-layer coating is necessary, therefore, the consumption of water-based paint per 1 m2 is 300 ml or 10 l per 35 m2. Depending on the manufacturer and type of paint, the price varies from 500 to 2000 rubles. for 10l of water-based paint.
