White water-based paint for outdoor use. Organic paints and varnishes. Requirements for facade paint.

Water based paint depending on the purpose, there are two types: water-based paint for interior painting and for exterior work. Different kinds water-based paint is designated by the type of film-forming substance and chemical composition.

Water-based paint is available in various colors and can be used on metal surfaces, plaster, concrete, brick and prepared wooden surfaces. Paints and varnishes have special indices assigned to them, which help to understand what they are made of and choose the necessary one with a fairly large assortment in the store.

Covered with a thick layer of varnish, which has already been partially completely omitted. It is blown out and the coating becomes brittle. Probably, it was badly or not at all primed, and also the glaze is not good if after such a short time it already makes its way. The spots where the varnish has already cracked earlier have turned black, which appear lighter with lighter colors.

Parking lots can be treated with a thin layer of varnish or a thick layer of varnish. Both have their own advantages and disadvantages. Thick-layer glazing gives a smooth, easy-to-clean surface. But it goes away somehow, and the subsequent treatment is more complicated. A good varnish should last 5 years with free weathering. With thin layer liners, you have a fairly rough wood surface that cannot be wiped clean. However, the wood remains exposed and uncoated. Thin-layer lasers emit over time, post-treatment is easier.

Various types of water-based paint are designated by the type of film-forming substance and chemical composition. For example, oil paints were assigned the MA index, alkyd-acrylics were assigned the AC index, glyphthalic-GF and other indices. Water emulsions have the following designation: E-VA; Z-AK; E-Sun; E-KCh and others.

Water-based paint of the E-VA-27 and E-VA-27A type consists of a suspension of pigments and fillers in film-forming aqueous dispersions based on PVA. Stabilizers, emulsifiers and other additives are added to the suspension. water-based paints used exclusively for painting work, which is carried out inside the interiors of houses. This water-based paint is applied on wood, concrete, stone, brick and other porous materials.

You can usually make your way quickly after cleaning. Oil glazes, which are mostly thin, absorb very well into the wood and adhere so well. By the way, a thick layer of glaze did not lead to the death of the tree. The reason for this is that the benches can dry well again.

The eucalyptus tree garden bench was originally glazed. The frosting went on pretty well, but worn out over time but not destroyed. However, it was also quite thin, these glazes do not tend to flake off. The bank was polished and counted. The wood has been darkened with oil, although it is not pigmented.

The composition is also applied on the primed metal surface. Dispersion polyvinyl acetate homopolymer coarsely dispersed (PVA) is a product of vinyl acetate polymerization in the presence of an initiator and a protective colloid in an aqueous medium. PVA dispersion is a viscous liquid white with a particle size of 1-3 microns and is toxic.

The varnish is problematic here because small imperfections on the surface force water under the varnish. This leads to discoloration and further flaking of the varnish. Well, it's probably best if you keep it on a regular basis. Post-treatment is very easy and fast in Tsl. On the other hand, painted surfaces can only be difficult to add, especially if they already look like the picture.

Still very intact with thick glaze. Clearly visible on the shiny layer on the wood. It is clear here that the oil-based paint penetrates deeply into the wood and forms a good bond with it. The surface is dull, because after the first layer almost no layer is formed on the wood.

It is used in water-based paints, for the preparation of glue for paper, linoleum, wood and other materials. Water-based paint Z-KCH-26 and Z-KCH-26A is a suspension of fillers and pigments in aqueous film-forming dispersions based on styrene-butadiene latex. Stabilizers and emulsifiers are also added to the emulsion.

Only other dyes result in a silky sheen. The seat is made of stencil printing plate. Although the edges are not sealed, it has very good strength during free weathering. This is a place with one playground. The covering layer has already been completely removed, and the other layers have been removed from the cutting edge, because the water penetrates more and more and the wood swells and depletes. Laminated glued panels on the outside do not have a long service life. However, in any case, it is worth fixing the cutting edges with varnish.

Wood surfaces treated with bright glaze quickly look unclean. For wherever cracks can penetrate the water, the wood turns gray or black. Often bright glazes are visible, heavily contaminated because water seeps in everywhere. It is very difficult to constantly maintain the bright color of the wood. Dark colors like dark brown or black work best outside. However, the wood becomes heavier, which is not always a good thing.

When applied to the surface of the material, the paint gives an even, uniform and matte film. The paint coverage is 70-220 g / m2. On the surface of the material water-based paint applied by roller, brush or spray. It is used only for interior types of work on metal, wood, concrete and plaster.

Water based paint for outdoor use

For outdoor use, the following types of water-based paints are used:

In some places, it begins to turn gray, especially where complete weathering occurs. However, the overall color is still pretty good. In the meantime, 6 years have passed. The facade is now completely gray. The exceptional color is only seen under the roof. In some places, the wasps gnawed at the wooden surface.

There is a strong contrast here. Another facade, also finished in a light tone. As a result, the gray hair of the tree is not visible. Where the color is shaded, you can see gray hair. Or the binder happens over time. Typically, thin-layer onlays are not as sharp, but medium to thick layers.

Z-AK-111, E-VA-17; E-VS-17, E-VS-114, E-KCH-112 and others. Paints of this type consist of suspensions of fillers and pigments using synthetic polymers in aqueous dispersions, with the addition of an emulsifier, stabilizer and other additives. When applied to the surface, it gives an even, uniform and smooth protective film of a matte appearance.

Emulsions - a group of thinners and binders for water and oil paint compositions. Emulsions greatly improve the quality of painting materials and save drying oil. In each emulsion, two phases are distinguished, internal and external. Therefore, there are two types of emulsion:

Screenshot from screen printing. Here you can see that bulletproof, multiplex or screen printing plates are not particularly suitable for appearance... Water enters the cutting edge. Due to the constant strong swelling and shrinkage, the wood disintegrates more and more. Already after 1-2 years, the layers dissolve in the marginal area; after 5 years, the destruction is often so strong that the component must be renewed. Sealing the edge can help something, but also after a short time.

The playground object that I finally looked at was already 7 years old and survived freely. The screen-printing plate used there was still top-notch, although no edge sealing was made. In a completely weathered project, this has been working for 7 years. Water does not penetrate the cutting edge.

water-in-oil (WO) and oil-in-water (MW).

In order to obtain the most stable emulsion, emulsifiers are added to its composition. In the role of emulsifiers, various substances are introduced such as soap, rosin, borax, lime, calcium chloride and others. Emulsions are diluted:

VM-drying oil, turpentine, white spirit.

These types of emulsions are called oil-soluble emulsions. Emulsions of the MB type are diluted only with water, therefore they are called water emulsions. E-KCH-112 water-based paint is not recommended for painting on wood, E-KCH-112 paint is not frost-resistant. Hiding power of water-based paints for outdoor types of work ranges from 60-230 g / m2.

Terrace tables are finished with a thick layer. This ensures that water does not penetrate the wood, but instead bubbles and runs off. Such a smooth finish is also very good at removing and bacteria can settle themselves so much. Well suited for gastronomic amenities. However, it should also be taken annually. This requires a bevel, which is a small force. perhaps anger also suffers. To prevent the layer from getting too thick, you can also use thin layer varnishes for post-processing.

Generally, solvent-based systems are more suitable, especially for post-processing. Unfortunately, there are practically no thin layer solvents that do not contain biocides. Two-story wooden facade. It was treated with a medium layered bright glaze. A technical mistake was made here: water descends from the roof onto the paving stones and splashes onto the facade. This is why this wet corner is getting more and more gray.

Work on painting facades and various building structures and products using this type of water emulsions is carried out at an air temperature of at least eight degrees Celsius. The paint is applied on plaster, concrete, wood and pre-primed metal surfaces.

Facade paint must meet a number of requirements. It must be resistant to sunlight, atmospheric precipitation, must have good vapor permeability and adhesion. Sometimes attention is paid to the speed of drying, consumption and other characteristics. There is a wide variety of facade paints. How to choose a facade paint?

Already an older sign in the Eiffel, which was structurally well protected by a cracked roof. The roof is covered with a roof, which is also quite durable. It was treated with a thin layer of varnish, which was destroyed in the lower left corner by insects. The text has been engraved, which is also a permanent solution.

A typical example of an unsuitable varnish in appearance. It was probably too complicated to begin with and messed up over time. Quite thick layers will also allow the wood floor to flake and flake. Unfortunately, there are still window varnishes that behave this way.

Facade water-based paints

Water-based facade paints are:

  • dispersive,
  • silicone,
  • lime,
  • silicate.

Water emulsion is the ideal paint for the facade wooden house... It is fireproof, permeable to air and vapors, odorless, tinting is possible. But usually water-borne facade paint is white. To maintain a clean facade, silicone paint is needed, which prevents dirt, and silicate material is suitable for painting concrete. The price of front water-based paints compares favorably with the background of organic paints and varnishes.

Bench finished with colorless or slightly pigmented beige glaze. Over time, the wood naturally dissipates and the wood turns gray. This provides a strong contrast. An information board that resolves quite well in some details: The roof ensures that there is some water in the rest of the tree. The sheet is mounted centrally from the roof so that no water flows there. The rest of the roof is an unoccupied tree that is so heavily loaded. Durability can be roofed lid.

The wood does not touch the ground below, which resists rotting. For an earthing ground fixed to an iron, which is also screwed quite far away, because the wood at the bottom will rot at some time. The pointer was written 16 and appears to have just been set. Location: Rechberg in Egggegebirge. A fairly light thin layer will be shaded after 3-4 years in more weathered areas. You can also see here that many small details determine how long such a bulletin board is kept.

Organic paints and varnishes

Facade paints requiring use organic solvents, are divided into enamels and oil. They do not let in vapors and air, but are resistant to aggressive manifestations the environment... Due to the fact that the material is resistant to moisture, the painted surface is easy to clean. But impermeability causes the paint to flake off over time. Careful removal of the previous coat is required before re-painting.

Metallic or raffian wallpaper, tiles or bookshelves - colors and varnishes protect and decorate alike. But not every color is perfect for every surface. Our guide will tell you what to look for when choosing colors and varnishes so that they can develop the desired effect for as long as possible. We will help you with your purchasing decision.

Interior paints for masonry, concrete, plaster and wallpaper

For interior surfaces such as interior walls and ceilings, especially suitable dispersion paints from synthetic resin. They contain synthetic resins, usually acrylic resins, as binders and water as solvents. Dispersion paints adhere well to most substrates, Primers, old dispersion paints, primed drywall and cement fiber boards, as well as masonry, plaster and concrete. They are easy to process, dilute with water and nonetheless resistant to washing.
