For wall finishing, water-dispersion paint is a popular and versatile option that is liked by many. Professionals and do-it-yourselfers alike now turn to this kind of paint because of its reputation for simplicity of application and quick drying times. It is particularly well-liked for its mildew and ease of cleanup following application, which makes it a practical option for indoor projects.
One notable feature of this paint is that it is primarily composed of water, which makes it easy to blend with other materials and produces a smooth, uniform coat. In addition, it provides outstanding coverage and a broad variety of finishes, from glossy to matte, making it appropriate for a variety of surfaces and design tastes. Water-dispersion paint provides a solution that strikes a balance between functionality and style, whether you’re looking to update the walls in your living room or update the appearance of your kitchen.
You can choose the best water-dispersion paint for your project by being aware of the various varieties available. Every kind, from latex variants to acrylic-based choices, has special qualities and advantages of its own. Whether you are working on walls, ceilings, or other surfaces, knowing how and where to apply each type will help you get the best results.
Definitions
The relationship between two types of paints, water-dispersion (w/d) and water-emulsion, is the source of most confusion. Let’s move quickly to make this clear.
- Aqueous dispersion is a mixture of water with any fine-grained material that is not soluble in it.
- A water emulsion is a special case of dispersion. Its only peculiarity is that both substances in the dispersed system are in the liquid phase.
For instance, milk is primarily an emulsion of fat and water, but since fat does not dissolve in water and forms a traditional dispersed system with it, it would be more accurate to refer to it as a dispersion.
Water-dispersion paint, which is more accurately referred to as water-emulsion in most cases, is composed of the following ingredients:
- Water;
- Synthetic or mineral binder;
By the way, lime or white cement are used to make mineral paints. And because both cement and lime are solid particles, the term "water-based" will be misleading for them specifically.
- Pigments (most often titanium white TiO2);
- Optional – functional additives (antiseptic, structuring, mineral fillers, etc.).d.).
The pigment-containing binder droplets adhere to one another and form a robust coating as the paint’s water base dries. It is possible to tint paints the desired color by using pigments that dissolve in water.
Regulatory requirements
The production of water-based paints is governed in our nation by standard number 28196-89.
What specifications then does GOST 28196-89 water-dispersion paint need to meet? Examining the document will lead to a surprising finding.
It only allows for the manufacture of five different kinds of paint:
Marking | Base | Application areas |
VD-VA-24 | Polyvinyl acetate (PVA) | Indoors (including wet areas – toilet, bathroom and kitchen) |
VD-KCH-26 | Styrene-butadiene latex | Only in dry rooms |
VD-AK-111 | Acrylate | Indoor and outdoor work |
VD-KCH-183 | Synthetic polymers (the text of GOST does not provide a complete list) | Indoor and outdoor work, except for surfaces that are subject to wet abrasion |
VD-KCH-577 | Synthetic polymers | Painting of fruit trees |
And these are some additional features of water-based paints made in compliance with the standard:
- Color and texture of the coating – white matte;
- The proportion of non-volatile substances (i.e. minus the water evaporating during drying) is from 47 to 60%
- The covering power of the film after drying is from 120 to 210 g/m2;
- The film"s resistance to water is 12 hours for VD-VA, 24 hours for VD-AK and VD-KCH-183;
Remarkably, latex is regarded as a washable and waterproof coating. But none of the latex water-based emulsions can claim to be moisture resistant as a family: In the column labeled "water resistance," VD-KCH-26 has a dash.
- Frost resistance – at least 5 cycles for all paints;
- Drying time – 1 hour per layer.
To be clear, touch-drying is what we mean when we discuss waiting to apply the next layer. Depending on the temperature and humidity, the paint takes one to three days to fully polymerize.
Consumer characteristics
A prospective buyer can’t learn much from dry numbers about which paint is best suited for painting the house’s facade or just the ceiling. Furthermore, not all water-based paints that are sold commercially are covered by GOST. As a result, we’ll allow ourselves to go back to the list of dye types and give a brief description of their characteristics for consumers.
These days, however, these paints are made with an enhanced recipe that includes copolymers, giving them new qualities and enabling outdoor use.
Application
Does painting walls or ceilings by hand pose a challenge? Let’s investigate.

Surface preparation
There are three stages to it:
- Cleaning old coatings. In general, water-based emulsion can only be applied on top of the same paint, using the same binder. Acrylic paint will not adhere to nitro enamel or oil paint;
But there are some exceptions. For instance, it is acceptable to apply rubber water-dispersion paint (on acrylic latex) over glyphthalic primer or alkyd enamel.
- Elimination of defects. Pots and chips are putty, protrusions are removed by grinding. After puttying, the wall is sanded and cleaned of dust (see. How to putty walls for painting);
- Priming. Penetrating primer reduces paint consumption (primarily during the application of the first coat) and makes the surface more durable. The primer must be of the same type as the paint (silicone, acrylic, silicate, etc.).d.).
In addition, paint can be used as a primer by diluting it with water. You won’t have to worry about the compatibility issues between different manufacturers’ soils and colors after reading this instruction.
Painting
Which instruments are suitable for painting?
Brushes, rollers, and spray guns are pretty standard. The author paints corners and other areas that are difficult for the roller to reach with a wide roller with a medium pile and a medium-width brush. Masking tape is helpful for shielding surfaces that aren’t meant for painting, and a paint tray is handy for extending the roller.
- Paint rollers: a detailed look
- Types of spray guns: how to choose the right one
- Paint brushes: which ones to choose
Note that a water-dispersion paint spray gun has a larger nozzle and a stronger compressor. These characteristics make up for emulsions’ higher viscosity. The paint is diluted by 5–10% with water before being applied with a spray gun.
Like in any business, understanding certain nuances is necessary to ensure a high-quality outcome.
- Manufacturers advise painting in at least two layers. In practice, they have to be applied 3-4. Consider this when calculating purchases;
- First, paint the internal corners, junctions with baseboards and moldings, and only then move on to large areas of ceilings and walls;
- For planes, it is better to use a roller rather than a brush. A brush leaves much more stripes;
- Use a paint tray. A well-rolled roller in it will give a thin, even coating. If you dip a roller in a can and roll it out on the wall, it will be much more difficult to make the color uniform;
- One plane is painted in one step. If you go on a smoke break without painting the wall completely, you will get a clearly visible thickening of the paint at the border of the painted area;
- Each layer is applied at right angles to the previous one. This way the streaks from the brush and roller are less noticeable;
- The last layer is applied parallel to the light from the brightest source in the room (chandelier, window, etc.).d.). This way, the inevitable streaks from the roller will be almost invisible.
Removal
If you wish to apply a dye that is incompatible with water-based paint to the surface, how can you remove it?
These are the two simplest methods:
- Soak the paint with hot (at least 70-80°C) water, then remove with a steel spatula;
- Instead of water, apply a penetrating primer to the painted surface on the same binder as the paint. After a few minutes, take up the spatula again.
