The market for paints and varnishes is very diverse today. But one of the most demanded coatings is always water dispersion paint. It is widely used for finishing ceilings, walls, wood and plasterboard surfaces.
Operating principle
Such paints are a homogeneous mixture of polymer components dissolved in water. Once applied to the surface, the water evaporates, leaving a pigment that forms a strong film that is resistant to water and air penetration.
The paint is well applied, has high adhesive properties, and tightly fills the pores. It has a creamy consistency and a mild, non-aggressive odor. The composition contains various fillers, antiseptic and strengthening agents that prevent the formation of mold.
Types of water dispersion paint
These paints differ depending on which binder is used in them - latex, acrylic or polyvinyl acetate (PVA). This affects the strength of the coating, moisture resistance, and, accordingly, the scope of application depends on it.
PVA-based water-based paint is one of the cheapest. It is mainly used for finishing ceilings. The water resistance of this paint is rather low, so it is not suitable for use in rooms such as a kitchen or bathroom. In addition, it gets dirty pretty quickly.
More expensive latex paint is recommended for any room humidity, creating more durable coating... Dirt and dust from such a surface can be removed very easily.
Water-based acrylic paint is even more durable and waterproof. It can be used not only indoors, but also outside (for example, for finishing the facades of buildings) and applied to wood and concrete surfaces. The acrylic paint is resistant to various weathering... It is widely used for painting ceilings and walls in rooms with any humidity.
Water-based paint and water-based paint: differences
Water is a common constituent of these materials, but they differ in many ways. One of the most important ones should be noted the high moisture resistance of water-dispersion paints. Water-based emulsion is quite easily washed off with water. Therefore, it is better not to use it for painting, for example, a bathroom.
When thickening, such materials are diluted with a substance similar in properties to the external phase, which in a water-dispersion paint is water, and in a water-based paint, as a rule, an alkyd varnish. The use of the appropriate solvent also depends on this. Therefore, in the first case, water will act as it, and in the second - white spirit.
Water-based paint can be the most different colors... Water dispersion is produced only in white version, but different shades, among which there are intended for coloring. Adding a color scheme allows you to get a huge variety of colors, which greatly expands the possibilities for solving any design idea. To give the paint a rich white color, a special pigment is added to it - titanium dioxide or zinc oxide. The filler function is performed by components such as chalk, calcite, mica, barite and talc. They contain both water-based paint and water-based paint. Differences in price, which largely depends on the manufacturer, are not very noticeable, but still water-based paint is somewhat more expensive.
Advantages of water-based paints
The popularity of these materials is especially high due to their ability to keep water out. This makes the coated surface more durable. At the same time, the ability of the paint to pass water vapor allows the walls and ceiling to "breathe".
Water-based paint is very resistant to temperature extremes and various negative atmospheric phenomena... She does not respond to household chemicalsthat allows you to wash and clean the painted surfaces without fear of their integrity. It is also a safe material that does not emit harmful and toxic substances. The paint dries pretty quickly, and the subtle smell disappears instantly.
You can apply this paint to any surface. The only exception is metal, since the presence of water in the composition can cause corrosion.
Application of water dispersion paint
Any surface should be prepared before painting. This contributes to better coating and significantly reduces paint consumption. For materials with a high degree of absorbency (concrete, plaster, cardboard), it is recommended to use a special treatment compound. But first, it is necessary to clean the work surface from dust and dirt, remove the previous coating, thoroughly cover up all cracks and crevices. Then a layer of primer is applied. And only after it has completely dried out, you can start painting the surface.
Water-dispersion (water-based) paint is applied with a roller, brush or spray gun. First of all, the corners are painted over with a brush and only then the rest of the surface is covered. It is most convenient to use a spray gun for this, which significantly speeds up the work process and allows you to penetrate the most hard to reach places, excluding the appearance of streaks and gaps on the surface.
If the water-based paint has stood for too long and thickens, it is diluted with water. It is recommended to paint any surfaces at an air temperature of 8-30 ⁰С. If work is carried out outdoors, exposure to precipitation should be avoided. If paint gets on your hands, it is easy to wash it off with warm water and soap.
It is not worth using such paint for surfaces that get dirty quickly. When dry, it acquires a certain roughness, which contributes to the rapid accumulation of dirt. This should be taken into account in cases where water-based wall paint is used.
For painting surfaces in residential premises, water-dispersed or water-based paints are most often used. Despite the fact that the basic substance in both cases is water, these compositions are still different.
Below we will consider the main differences between water-dispersion and water-based paints. To understand what they are, it is necessary to take into account the technical indicators: composition, consumption, viscosity, hiding power, specific gravity, durability, as well as features of the use of materials.
This type of paintwork materials is widely known to the domestic user and has found application in many areas due to the following advantages:
Among the disadvantages should be noted exposure to low temperatures, especially at the time of application. The working temperature should be above 5 degrees. Besides, given view material should not be applied to hardware or surfaces that absorb a lot of moisture. In the first case, the paint will cause corrosion, in the second, premature destruction of the surface.
Water-based paints are intended exclusively for interior or facade works
Specifications
Ingredients such as latex, thickeners, fillers and optional additives to increase water resistance are included in the water-based paintwork materials, ultraviolet rays etc. The viscosity of this material is controlled by water. To determine this indicator is used special tool - viscometer. Optimal indicator viscosity - 40-45 St when using hand tools (rollers, brushes, sponges and others). If it is planned to apply the material by means of a spray gun, then this indicator should be no more than 25 Art.
If we take the average data provided by manufacturers, then the consumption of water-based paint is 200 ml per 1 square meter processed surface. But in fact, this characteristic may be different due to the absorbency of the base, the degree of its preparation, the tool used, and so on.
The technical characteristics of water-based formulations directly depend on the main filler The average specific weight of this type of paint does not exceed 1.4 kilograms per liter. Drying time directly depends on the humidity and temperature in the room. Also different compositions can dry different time: from 2 hours to a day. It should also be noted that it is better to carry out painting work at a temperature of about 20 degrees Celsius and a relative humidity of 65-70%.
Types of water-based compositions
The modern construction market offers the following types of materials:
- Acrylic. As the name implies, the material is based on acrylic resins. These compounds are considered to be of sufficient quality, strong and durable.
- Mineral. Slaked lime or cement are additional ingredients. Paints are capable of hiding small defects in the treated surface, but they do not last long.
- Silicate. They are a mixture of liquid glass, dye and solvent. They can last up to 20 years without losing their original appearance.
- Silicone. The strongest and most durable materials, but, unfortunately, very expensive. This is mainly what distinguishes formulations from water-based paint.
Water-based paints
This kind finishing materials manufactured on the basis of synthetic polymer substances and aqueous dispersions. Acrylic or vinyl acetate polymers are used as binder. If the question arose, how does water-based paint differ from dispersion compositions, then the latter are more widespread due to their high performance. These materials have the following advantages:
- Lack of volatile components. Thanks to this feature, surfaces can be painted without respirators.
- Easy to apply. Even a novice home master can cope with painting.
- Drying speed. Usually one layer of paint hardens in half an hour.
- Resistance to ultraviolet radiation... Thanks to this, the coating retains its original color for a long time.
- High level of adhesion to many types of substrates.
- Water vapor permeability. This feature allows the coating to "breathe" so that moisture will not accumulate on the surface.
- Durability. Provided that the starting work is carried out correctly, the coating can last 20-25 years.
There is water in the composition of water-dispersion paints, but polymer additives give unique characteristics, it is these additives that provide an elegant shine, moisture resistance and strength The main disadvantage against the background of water-based compositions is the high cost.
On a note! You can find inexpensive dispersion compositions, but then you have to apply them in several layers, which, in the end, will lead to significant monetary costs.
Also, this type of paint requires a perfectly prepared base. It needs to be leveled, cleaned, treated with impregnations, and only then can it be painted. A common drawback of these materials is their limited operating temperature.
Output
Despite the fact that most of the composition of the presented paints is occupied by ordinary water, they can differ significantly in cost. In addition, materials differ in terms of covering ability.
It should also be said that dispersed paints are resistant to water, while emulsion paints are easy to wash off the surface. Also, the materials differ in the solvent used. To control the density of dispersed compositions, use water, emulsion - white spirit. In addition, the first option is produced exclusively in white, while the second can be multi-colored or tinted.
In this article we will talk about which paint is better - water-based or water-based and what are the characteristic differences between these two compositions. In fact, these are different paints and varnishes. In spite of the fact that both of these coatings to one degree or another, consist of water.
In order to understand how water-based paint differs from water-based paint, you need to pay attention to specifications LMB.
Among them we would like to highlight:
- composition;
- viscosity;
- consumption per square meter;
- specific gravity;
- shelf life and optimal storage conditions;
- operational features.
Water based paints
And this is not surprising, since the following advantages are characteristic of water-based compositions:
- fast drying (several hours on average);
- ecological cleanliness and safety and, as a result, there is no need to use personal safety equipment when carrying out finishing work;
- lack of a specific pungent odortypical for most traditional enamels.
- the ability to give the coating a particular color by adding special pigments.
- simple instructions for applying paintwork and the availability of toolsrequired to complete painting works;
- affordable price.
Important: Water-based coatings have some disadvantages. Among them - carrying out painting work at a temperature of at least + 5 ° C.
Main characteristics
- The composition of water-based paints includes components such as filler, latex, thickener and antiseptic additives.
- The viscosity determines how diluted the dye mixture is with water. To measure this parameter, a special tool is used - a viscometer. On average, the viscosity should not exceed 45 Art.
The composition of mineral water-based coatings includes cement or slaked lime. Such paints and varnishes are used for application on most different surfaces... The disadvantages of these compositions include a small operational resource.
Water-based silicate materials are a mixture of water glass, water solution and pigments. Such coatings are characterized by high degree vapor permeability, as well as resistance to atmospheric precipitation and temperature differences... On average, a properly applied coating has a lifespan of about 20 years.
In silicone water-based paints, silicone resins are used as a binder. Such compositions are an order of magnitude more expensive than analogues, but also have high strength and durability.
Water-based paints
As already mentioned, the main difference between water-based paint and water-based paint is its composition. Water-dispersion paintwork materials are made on the basis of polymers and water dispersions. The binder is acrylic and vinyl acetate polymers.
Currently, the share of water-dispersion compositions on the paint and varnish market is about 60% and this figure is increasing every year.
Features of water dispersion paints
In the photo - the consistency of paints and varnishes
Water-dispersive paintwork materials are characterized by:
- lack of organic volatile solvents;
- simplicity and availability of application methods;
- fast drying (on average, it takes no more than 30 minutes to dry one layer);
- stability;
- high adhesion to different types surfaces, including previously painted coatings;
- good vapor permeability;
- durability (up to 20 years at competent preparation grounds).
There are also disadvantages, including:
- application at a temperature not lower than + 5 ° С;
- the need for high-quality preparation of the working base;
- high price in comparison with the water-based analogue.
Output
So, we figured out if there is a difference between water-based and water-based paint and how significant it is. Despite the fact that both those and other paints and varnishes are made using water, there is a difference. First of all, it is the price and hiding power indicators.
For example, a water-based coating exhibits 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-dispersive analogues. The choice of these, in many respects similar, but at the same time different paintwork materials should be carried out based on the parameters of the base and the operating conditions of the finished coating.
More useful information on this topic, you can discover by watching the video in this article.
The choice of new paint and varnish products pleases with its own diversity of each person who has begun repairs. Many find themselves in front of the selection, which preference to give - water-based or water-based paint. To do this, it is necessary to determine what is the difference between them, and what important specifics are inherent in any of the species.
Properties and specifics of two types
In order to establish what are water-based and water dispersion paints, and also, how they differ, it is worth considering several significant factors:
- their constituent elements;
- specific gravity;
- viscosity;
- consumption;
- specifics of use;
- expiration dates.
Water emulsion
First of all, let's get acquainted with water-based paint and its key parameters. This type of coating contains water with particles of special polymeric materials and pigments. Sometimes mineral, acrylic or silicone resins are also found. You can change the viscosity of such a paint by adding a specialized solvent in various quantities.
Average consumption water dispersive paints - about 210 ml of the product per 1 square meter of the painted area. However, this indicator tends to vary depending on the type of surface, the degree of thinning and other factors. Specific gravity This type of coating is generally no more than 1.5 kg.
The main advantages inherent for this type of paint are:
- high level of environmental safety;
- eternal lack of smell when the coating dries;
- ease and ease of application;
- comfortable color change by tinting;
- a large selection of tools for application;
- cost-effective and attractive price.
Nowadays, there are several varieties water dispersive paints, any of them has its own unique properties:
- mineral;
- acrylic;
- silicone;
- silicate.
All of them stand out among themselves both in composition and in the area of \u200b\u200buse. The cheapest option is mineral water-based coatings. They are mainly based on cement or slaked lime. Such coatings are used for painting a wide variety of surfaces, but they cannot boast a long service life.
The most popular multipurpose option is an acrylic water emulsion. It is perfect for covering plaster, wood, brick and concrete surfaces, as well as glass and metal.
A much more expensive coating is a silicone water-based emulsion based on high-quality silicone resins. You can cover with this paint various options surfaces.
For rooms with very high level moisture, it is best to use silicate water emulsions, which contain liquid glass, and also, coloring pigments.
Water dispersion
Now let's move on to water-based paints. These coatings are based on aqueous dispersions, as well as acrylic, latex or polyvinyl acetate components for the bond. Therefore, the area of \u200b\u200buse of the paint is different, as well as its reliability and waterproof properties.
The most primitive and cheapest way is considered water-based paint PVA-based - polyvinyl acetate. In many cases, it is she who is used to paint ceilings in the most different rooms... It is highly undesirable to use it in the kitchen and bathroom due to the reason of low moisture-resistant skills. Another serious drawback of this type of paint is its tendency to get dirty rather quickly.
The second type is latex water dispersion. The coating she performs is considered to be very strong and resistant. It is also worth saying that it is not at all afraid of either dirt or water.
And finally, the third type of paint is acrylic water dispersion. Thanks to its own high protective properties and exemplary resistance to bad weather, it is perfect for use both in the middle and outside of buildings of various types. It can be applied on concrete and wood surfaces, walls and ceilings. Very high humidity does not threaten such a coating at all.
Important specifics and advantages of water-based paints
When using water-based paints, it is necessary to take into account what specifics are distinctive for them:
- temperature environment to use this type of coating should be more than + 5 ° С;
- given paint dries completely two hours after application;
- this type of coating is able to ideally fill small cracks and crevices, thanks to this it does not require overly diligent preparation of surfaces.
Among the most important advantages that are characteristic of them, it should be noted:
- durability of the coating;
- good "breathing" ability;
- high resistance to temperature extremes;
- non-exposure to the action of aggressive household products;
- lack of toxic substances in the composition;
- actually compatible with the most different types surfaces, the only exception is metal, contact with which provokes corrosion;
- the absence of an unpleasant irritating odor.
Talking about positive qualities water emulsion, I would like to highlight:
- high setting speed;
- lack of bad smell and harmful elements;
- normal color change using pigments;
- ease of application and a large selection of tools used for these purposes.
Are there any differences
Regardless of the identical names, properties and compositions, there are slight differences between water-based and water-based paints. Water-based emulsion ones are characterized by better covering ability, while water-dispersion ones are considered very strong. The cost of water-based paints is generally much less.
Knowing what qualities and good qualities own two of these popular types of paints, you will not make a mistake in your own selection. The main thing is to give preference to coatings made by manufacturers with an ideal reputation.
Sooner or later, each of us has to think about repairing our "personal environment", no matter if it is permanent or temporary. And already at the planning stage of repair and construction work, a lot of questions arise, and some of them have no clear answers from home-grown foremen. One of the main problems is the choice of building materials. Today, the assortment of specialized stores is so rich that it is often necessary to consult a specialist in order to figure out, for example, what is the difference between water-based paint and water-based paint.
We did not use paint as an example for nothing. paints and varnishes (hereinafter paintwork materials) are one of the most important components of any repair. Moreover, paint on water based - some of the most popular because of their relative cheapness and environmental benefits. Therefore, as you probably already guessed, our article will focus on them. Immediately, we will say that these are very similar in composition and properties of paintwork materials, but some differences between them are still present.
Water-based paint (VEM)
This type of paintwork materials belongs to the old and well-known building and finishing materials. At one time, it was the main paint used in construction as on household leveland industrial.
Water-based paints have a number of advantages:
- lack of smell;
- fast 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 dispersion paint).
The VEM contains water, which contains a suspension of polymer particles and a coloring pigment, plus all sorts of additives. There are paint types with silicone or acrylic resin binders. Let's 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 paint jobs. However, this type of paint has a major drawback - it is short-lived. Although, on the other hand, this disadvantage is offset by its low price.
The optimal universal paint coating today is considered to be an aqueous emulsion with polyacrylate in its composition. It is relatively inexpensive, fits on almost all major surfaces and has a long service life.
And, finally, a water emulsion, the main component of which, in addition to water, is a silicone resin. Is different high quality and appearance... Suitable for all paint jobs and surfaces. The most persistent in comparison with “colleagues in the shop”. It has one, but quite a significant drawback - it is the most expensive option among water-based paints.
Water dispersion 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 recent times water dispersion paints are widespread. They became, as it were, a further development of VEM. A constituent element of the VDK is an aqueous dispersion bound with 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, of course, the most popular against the backdrop of the desire for universal savings. However, the low cost is not due to some kind of philanthropy on the part of the manufacturers, but rather tangible shortcomings. It should not be used in rooms with high humidity, she is very easily soiled. That is, a bathroom, a kitchen are immediately excluded from priority objects, and this significantly reduces the scope of its use in finishing works and household repairs.
Latex paint is much better quality, it is not afraid of moisture, it washes well and the problem of pollution does not scare it. However, the price is already higher.
Last on the list is acrylic water dispersion. As you probably already guessed, the best, highest quality, universal, etc. But all good things have to be paid for. Unsurprisingly, this is the most expensive paint in the water dispersion group.
Let's list the main advantages of paintwork materials on a water dispersion basis:
- fast drying - from 30 minutes to 2 hours, depending on the composition of the VDR;
- resistance to fading in the sun (ultraviolet);
- excellent adhesion (adhesion) to almost any surface;
- breathes well (vapor permeability);
- high durability (up to 20 years, subject to strict adherence to the technological process).
But there are spots on the sun too. The most noticeable is the high demands on the performance of paintwork. Only thorough adherence to all conditions for painting guarantees a high-quality result:
- thorough preparation of the painted surface;
- strict adherence to proportions when thinning paint with a solvent;
- applying the number of layers - exactly as much as indicated in the instructions;
- does not like cold, during operation the temperature should not be lower than +5 0 С (this also applies to VEM).
Water dispersion is produced, as a rule, white, but this can be easily corrected by adding the desired color pigment.
Comparison
Comparing everything that we have learned about these types of paintwork, we can say that they are close relatives, but not twins. Differences are small, but there are. Let's write them down in the table for clarity.
Table
So, we hope our article has given you a clear idea of \u200b\u200bwhat is the difference between water-based paint and water dispersion paint, which means that when you visit a construction supermarket, you will not have to be embarrassed by asking busy consultants about the advantages and disadvantages of these paintwork materials. Now you are well-versed in this matter and you yourself can consult anyone.
