Sooner or later, each of us has to think about repairing our “personal living environment”, no matter whether it is permanent or temporary housing. And already at the planning stage of repair and construction work, a lot of questions arise, and home-grown foremen do not have clear answers to some of them. One of the main problems is the choice of building materials. Today, the assortment of specialized stores is so rich that consultation with a specialist is often required in order to understand, for example, how water-based paint differs from water-dispersion paint.
It’s not for nothing that we used paint as an example. Paints and varnishes (hereinafter referred to as paints and varnishes) are one of the most important components of any repair. Moreover, water-based paints are among the most popular due to their relative cheapness and environmental advantages. Therefore, as you probably already guessed, the conversation in our article will be about them. Let’s say right away that these are very similar in composition and properties of paints and varnishes, but there are still some differences between them.
Water-based paint (WEM)
This type of coatings belongs to old and long-known construction and finishing materials. At one time, it was the main paint used in construction at both the domestic and industrial levels.
Water-based paints have a number of advantages:
- no odor;
- quick drying (on average 2-6 hours, complete drying up to 24 hours);
- environmental Safety;
- ease of use;
- availability and low cost.
Most of these advantages are, to one degree or another, inherent in VDK (water-dispersed paint).
The composition of VEM includes water, which contains a suspension of polymer particles and a coloring pigment, plus all kinds of additives. There are types of paint with binders made of silicone or acrylic resins. We list the most common types of water-based paints:
- acrylic;
- silicate;
- silicone;
- mineral.
The cheapest and well-known paint is based on mineral additives (lime, cement). It is widely used in many painting works Oh. However, this type of paint has a major drawback - it is short-lived. Although, on the other hand, this minus is compensated by its low price.
The optimal universal paint coating today is considered to be a water-based emulsion with polyacrylate in its composition. It is relatively inexpensive, suitable for almost all major surfaces and lasts quite a long time.
And finally, a water-based emulsion, the main component of which, in addition to water, is silicone resin. It is of high quality and appearance. Suitable for any painting work and surfaces. The most persistent in comparison with “colleagues in the shop”. It has one, but quite significant drawback - it is the most expensive option among water-based paints.
Water-dispersed paint (WDC)
As we mentioned at the beginning of the article, the difference between water-based paint and water-based paint is minimal. So now we will give General characteristics VDK, and only then we will move on to the differences between them.
IN Lately water-dispersion paints have become widespread. They became, as it were, a further development of VEM. The constituent element of the VDC is an aqueous dispersion bound by polyvinyl acetate, acrylic or latex components. Accordingly, there are 3 main types of this paint:
- based on PVA;
- latex;
- acrylic water dispersion.
Polyvinyl acetate (PVA) paint is the cheapest and, naturally, the most in demand amid the desire for general savings. However, the low cost is not due to some philanthropy on the part of the manufacturers, but to quite tangible shortcomings. It should not be used in rooms with high humidity, she is very easily soiled. That is, the bathroom and kitchen are immediately excluded from priority objects, and this significantly reduces the scope of its use in finishing works ah and household repairs.
Latex paint is of much higher quality, it is not afraid of moisture, washes well and is not afraid of the problem of contamination. However, the price is already higher.
The last one on the list is acrylic water dispersion. As you probably already guessed, the best, high-quality, universal, etc. But you have to pay for everything good. It is not surprising that this is the most expensive paint among the members of the water-dispersion group.
Let us list the main advantages of paints and varnishes based on water dispersion:
- quick drying - from 30 minutes to 2 hours, depending on the composition of the VDR;
- resistance to fading in the sun (ultraviolet);
- excellent adhesion to almost any surface;
- “breathes” well (vapour permeability);
- high durability (up to 20 years, subject to strict adherence to the technological process).
But the sun also has spots. The most noticeable thing is the high requirements for painting work. Only thorough compliance with all painting conditions guarantees a high-quality result:
- thorough preparation of the surface to be painted;
- strict adherence to proportions when diluting paint with a solvent;
- applying the number of layers - exactly as indicated in the instructions;
- does not like cold, during operation the temperature should not be lower than +5 0 C (this also applies to VEM).
Water dispersion is usually produced white, but this can easily be corrected by adding the desired color pigment.
Comparison
Comparing everything we have learned about these types of paintwork materials, we can say that they are close relatives, but not twins. The differences are small, but they exist. Let's write them down in a table for clarity.
Table
So, we hope that our article has given you a clear idea of the difference between water-based paint and water-based paint. This means that when you visit a construction supermarket, you won’t have to be embarrassed asking the ever-busy consultants about the advantages and disadvantages of these paints and varnishes. Now you are quite savvy in this matter and can advise anyone yourself.
Water-based acrylic paint is in great demand when carrying out work indoors and outdoors. This variety is resistant to various kinds influences. Naturally, in addition to many advantages, the material also has disadvantages. Correct assessment of the features of this composition is the key to obtaining a reliable and durable surface.
How do these materials differ from each other? A water-based composition is a large group of mixtures for which water is the solvent. The final properties of the product depend on the additives; they can be polymer or mineral.
Acrylic solution is a type of water-based emulsion. The composition of this mixture is: dye, polymer emulsion (in this case acrylic), distilled water and special additives to improve characteristics. Thus, a more modern composition with excellent qualities is obtained.
Differences:
- Water-based paint is often associated with traditional paint that contains chalk or slaked lime. Basically, such mixtures are prepared independently with the addition of PVA.
- Differences in GOST. This normative document reflects everything specifications material. Under number 28196-89 there is water-dispersion paint, which often has a more popular name - water-based emulsion. Such confusion arises due to the fact that the expansion of GOST occurs very slowly. The characteristics specified in 1989 no longer correspond to the range of products on the market.
It turns out that acrylic composition is an improved type of water-based paint.
Technical characteristics of acrylic compositions
Acrylic paint has properties that distinguish it from classical materials:
- Good viscosity. The solution does not drain from the surface, which ensures uniform distribution and quick fixation.
- Light weight. This eliminates the overall load even on a fragile base, such as drywall.
- Good hiding power.
The composition is applied at temperatures above +15 and humidity 65–70%. Other specifications vary by manufacturer.
Advantages of the material
Acrylic water-based paint has many advantages:
All these qualities ensure the great popularity of the material.
Disadvantages of acrylic solutions
The disadvantages of products do not seem so significant compared to the advantages, but they can play an important role in the choice. Among the negative points stand out:
- Expensive.
- The price of this composition exceeds the cost of other varieties, which is compensated by the hiding power of the paint. This indicator reduces the number of layers required and mixture consumption. Not too high vapor permeability. But this is not always a serious disadvantage. For example, concrete surfaces have low vapor permeability, but they are the ones most often found in ceiling structures
needing coloring.
When choosing products, all available features are taken into account.
Varieties of mixture
There are several varieties of acrylic water-based paints, which are divided according to their purpose: Acrylic washable paints can withstand approximately 1500 – 3000 cleaning cycles
Attention! The main thing when choosing is to give preference to trusted manufacturers and purchase goods in specialized stores.
Is it possible to apply acrylic paint over water-based paint?
Such painting is allowed if there is no damage, swelling or peeling on the surface, if re-painting is required when laying in several layers and if the compositions used are similar. The fact is that the acrylic version is not applied to all varieties without consequences. water-based compositions.
In other cases and in the absence of confidence in the final result, it is better to completely clean the coating.
In this article we will talk about which paint is better - water-based or water-dispersion and what are the characteristic differences between these two compositions. In fact, these are different paints and varnishes.
Despite the fact that both coatings, to one degree or another, consist of water.
In order to understand the difference between water-based paint and water-dispersion paint, you need to pay attention to the technical characteristics of paints and varnishes.
A wide range of color versions of water-based compositions
Among them we especially note:
- compound;
- viscosity;
- consumption based on square meter;
- specific gravity;
- expiration dates and optimal conditions storage;
- operational features.
Water-based paints
The most popular tool for applying water-based and water-dispersion paint
And this is not surprising, since water-based compositions have the following advantages:
- quick drying(on average several hours);
- environmental cleanliness and safety and, as a consequence, there is no need to use personal safety equipment when carrying out finishing work;
- no specific pungent odor, characteristic of most traditional enamels.
- the ability to give the coating a particular color by adding special pigments.
- simple instructions application of paints and availability of tools necessary to perform painting works;
- affordable price.
Important: Water-based coatings have some disadvantages. Among them is carrying out painting work at a temperature of at least +5° C.
Main characteristics
On photo applications water-based coatings as a coating for decorative plaster
- The composition of water-based paints includes components such as filler, latex, thickener and antiseptic additives.
- Viscosity determines how much the dye mixture is diluted with water. To measure this parameter it is used special tool– viscometer. On average, viscosity should not exceed 45 Art.
Important: If you use a spray gun rather than a paint brush to apply paint compositions, the viscosity parameters should not exceed 20-25 Art.
- The consumption of water-based paints when applied in one layer is, on average, 200 ml per square meter. However, consumption is largely determined not only by the characteristics of the coating, but also by the absorbency of the base.
- The specific gravity of coating materials does not exceed 1.40 kg/l.
- Drying times depend on air humidity and room temperature. Depending on the brand of paintwork, drying can last from 2 hours to a day. Optimal temperature during painting work it is considered +20° C with a humidity of no more than 65%.
Types of water-based paints
On photo-water emulsion composition with latex added
The difference between water-based and water-dispersion paint lies in the difference in composition.
In accordance with the composition, the following types of water-based coatings are distinguished:
- acrylic;
- mineral;
- silicate;
- silicone.
Acrylic compositions are the most common and in demand. The main component in this case is acrylic resins. To increase the hydrophobicity of the coating, latex is added to the paintwork material.
Important: Acrylic water emulsion with latex filler, when laid in two layers, fills and masks cracks up to 2 mm wide.
Acrylic coating fits equally well on wood, brickwork, concrete, plaster, glass and metal. A typical example is fire-retardant paints for metal Polistil. These coatings, despite their specific purpose, are universal and can be applied to any pre-primed surface. (See also the article How to putty walls: features.)
Mineral water-based coatings contain cement or slaked lime. Such paints and varnishes are used for application to most various surfaces. The disadvantages of these compositions include their short service life.
Water-based silicate materials are a mixture liquid glass, aqueous solution and pigments. Such coatings are characterized high degree vapor permeability, as well as resistance to precipitation and temperature changes. On average, the service life of a properly applied coating is about 20 years.
Silicone water-based paints use silicone resins as a binding component. Such compositions are an order of magnitude more expensive than their analogues, but are also distinguished by their high strength and durability.
Water-dispersion paints
The photo shows water-dispersion paint
As already mentioned, the main difference between water-dispersion paint and water-based paint is the composition. Water-dispersed coatings are made on the basis of polymers and water dispersions. The binder components are acrylic and vinyl acetate polymers.
Currently, the share of water-dispersed compositions on the paint and coatings market is about 60% and this figure is increasing every year.
Features of water-dispersion paints
The photo shows the consistency of paints and varnishes
Water-dispersed coatings are characterized by:
- absence of organic volatile solvents;
- simplicity and accessibility of application methods;
- quick drying (on average, it takes no more than 30 minutes to dry one layer);
- paint resistance to ultraviolet radiation;
- high adhesion to various types surfaces, including previously painted coatings;
- good vapor permeability;
- durability (up to 20 years at competent preparation grounds).
Zinga electrically conductive paint ensures longer service life
There are also disadvantages, including:
- application at a temperature not lower than +5° C;
- the need for high-quality preparation of the working base;
- high price in comparison with a water-based analogue.
Conclusion
So, we figured out whether there is a difference between water-based and water-dispersion paint and how significant it is. Despite the fact that both paint and varnish materials are made using water, there is a difference. First of all, these are the price and coverage indicators.
Eg, water-based coating demonstrates better hiding power. This is important when applying it yourself. But the price of such compositions is an order of magnitude higher than the cost of water-dispersed analogues. The choice of these, largely similar, but at the same time different paintwork materials should be made based on the parameters of the base and the operating conditions of the finished coating.

Acrylic paint is universal material, used in the repair and finishing of a number of structures. There are numerous types of paints, suitable for individual jobs and differing in the composition of the binder and modifier additives. The most common are water-based paints containing acrylic resin as the main film-forming component. To begin with, we will talk about the difference between acrylic water-dispersion and water-based paint.
What is the difference between acrylic water-dispersion paint and water-based paint?
Many people wonder what the difference is between water-based paints. In household and professional purposes Both terms can be used. The difference between acrylic water-dispersion and water-emulsion paints lies only in the breadth of concepts - dispersion implies the presence tiny particles(liquid or solid) in a dispersion medium.
If these particles are liquids, then the dispersion is called an emulsion.
Suspensions, which are dispersed suspensions of solids, are not included in acrylic-based paints and varnishes. All acrylates are added to paints in the form of highly viscous liquids and belong to the class of emulsions.
Features and Specifications Acrylates have a number of useful qualities
- , which led to their wide distribution in the domestic and professional sphere. The main advantages of water-dispersion compositions are: resistance to external mechanical impact
- and solar ultraviolet radiation;
- immunity to moisture (except for the cheapest low-quality paints);
- short drying time (a new layer can be applied an hour after the previous one); absence of toxic components and unpleasant odors
while working. The operational parameters of water-based acrylic paints and their technical characteristics are standardized by GOST 28196-89. The standard establishes paint grades and regulates technical requirements
- to them. List of controlled parameters:
- color;
- appearance of the polymer film after the solvent has dried;
- proportion of non-volatile substances (resins and pigments);
- hiding power;
- light fastness;
- resistance to water;
- paint pH;
- drying time;
frost resistance.
Water-dispersed acrylic paints are designated by the code “AK”. The nature of the solvent (water) is indicated by the abbreviation “VD”. In total, there are two brands of acrylic paints: brand “111” is universal (for), and brand “111r” is intended for giving the surface a relief structure.
Popular manufacturers and cost of materials The price of 1 kg of acrylic water-based paint (mixture) is 70-90 rubles. and more. The cheapest compounds have weak strength and anti-wear properties, so they can be easily wiped off mechanically after drying. Mixtures medium price category
It is better to purchase water-based paints in specialized stores that provide proper storage conditions for products sensitive to low temperatures. The vast majority of water-dispersion paints delaminate upon freezing and subsequent thawing, which makes them unsuitable for further use.
Well-known and popular manufacturers of acrylic water-based paint include:
- “Lakrit” is a wide range of acrylate dispersions covering a significant area of use (this acrylic water-based paint is intended for interior and exterior work, restoration, and has an average price);
- “Ultraweiss” is a durable acrylic paint that requires artificial tinting (available in the form of a white emulsion);
- "Tikkurila" is one of the most quality compositions, characterized by high resistance, durability and cost;
- "Derufa" is one of famous paints domestic, forming durable and aesthetic coatings.
Acrylic water-based paint is also produced under the brand name “Caparol”, as discussed in the following video:
Types of such products
The following types of paints and varnishes are distinguished:
- atmospheric – withstands any weather conditions and is intended for external application on the surfaces of buildings and industrial structures;
- façade – used for protection external parts structures and can have a smooth or embossed texture of the polymer layer. This is used along with atmospheric;
- For interior works– guarantees the effectiveness of the formed coating when working indoors. Such paints are often universal and are used simultaneously for internal and external application;
- washable - this water-based acrylic paint contains the highest quality acrylic binders, forming a durable polymer film that is not exposed to water. Conventional paints can only withstand dry cleaning and can “float” after wet cleaning;
- acrylic-based - the main component of the binder in this water-based paint is acrylates. A number of water-based paints that are not classified as acrylic can be made based on latex, vinyl acetate and other synthetic polymers. It’s quite difficult to say for sure which paint is better to buy (water-based, acrylic or another), it all depends on your requirements.
Today on store shelves it is not difficult to find acrylic-based water-based paints for many types of surfaces, including wood, as discussed in the review of the material in the following video:
Features of application and mixing
So, is it possible to mix water-based paint with acrylic paint? One of the advantages of acrylic water-dispersion paint is high adhesion to a variety of surfaces.
Application of acrylates over a hardened layer of water-based paint is allowed and is the main method of painting if stripping the old coating is not possible. Acrylic water-based paints are an adequate replacement for non-aqueous enamels. Availability of formulations, non-toxicity and short term
drying conditions make it possible to use acrylate mixtures for a wide range of economic and industrial purposes. Choosing paint for finishing work is always a responsible and very important stage
, since among all kinds of paint and varnish products it is necessary to choose exactly the one that would meet not only household requirements, but also decorative expectations. At the same time, the variety of finishing coatings can play a cruel joke on the consumer, leading them into a dead end with another new product on the construction raw materials market. For example, few people know how water-based paint differs from water-based paint that is similar in name. But, despite the common water base, these are two different paints and varnishes. We will explain below what their differences are.
To understand the difference between water-dispersion and water-based paint, you should refer to the technical characteristics of each product. Among them, a special role is played by the composition, characteristics of operating conditions, consistency/viscosity, specific gravity, consumption per 1 m2 and shelf life, subject to storage rules.
Features of water-dispersed mixtures Water-dispersion paint differs from water-based coating, first of all, in composition. Such products are produced on the basis of an aqueous dispersion and polymers diluted in it. In such mixtures, the binding elements are vinyl acetate and acrylic chemical compounds
. Recently, water-dispersion coatings are one of the most popular, the demand for which is constantly growing. Such coloring compounds
characterized by the following properties:
· Practicality of application; Good adhesion to;
different materials Resistant to ultraviolet rays and other influences;
Increased resistance to conditions high humidity;
· Quick drying of the applied layer (up to half an hour);
· Vapor permeability of the finished coating;
· Lack of volatile solvents;
· Long service life (with proper preparation, the coating will last up to 20 years);
· Wide selection of shades for tinting.
At the same time, it has some nuances. Such a composition requires preliminary and quality training base before paint is applied, and work can be carried out at an ambient temperature of at least +5⁰С. At the same time, the water-dispersed paint mixture differs more affordable price and its consumption per 1 m2 is on average 130 g.
Features of water-based mixtures
These paints are no less common than the previous type of paint and varnish products. However, they have a different composition, which includes: water base, latex, thickener, coloring pigments, filler. Water-based coatings differ from the previous type of coating described above in several respects:
· More a long period drying (from 2 to 24 hours);
· Better hiding power;
· Consumption per 1 m2 – on average about 200 g.
In addition, there are four types of paints that represent and differ in composition. These are acrylic water-based mixtures, silicate and silicone, as well as mineral.
What do we get as a result?
To summarize, it is worth noting that water-dispersion and water-based paints, which are somewhat similar in name and composition, have significant differences. They are determined by the combination of components included in the composition and the technical characteristics declared by the manufacturers. At the same time, these coatings are environmentally friendly. Therefore, when using them, they will not arise allergic reactions and the indoor microclimate will not change. As for storage, each of the two presented above coloring mixtures It is recommended to keep at a temperature of 0 - +30⁰С, avoiding freezing.
Faced with the need to choose the right one paint material for finishing, it is important to know not only the differences in compositions. It is also important to take into account the structure of the surface being treated, as well as the operating conditions and their compliance with the type of coating.
