Pros and cons of water-dispersion facade paint

The exterior paint color you choose for your house can have a big impact on how it looks and how long it lasts. Water-dispersion facade paint is one common option that many homeowners take into consideration. This kind of paint is designed specifically to endure the weather while producing a long-lasting and appealing finish. It’s important to weigh the benefits and drawbacks to decide if this is the best option for your project.

The ease of application of water-dispersion facade paint is one of its main advantages. This kind of paint spreads evenly and smoothly, requiring less work to produce a polished appearance. It also dries rather quickly, which facilitates finishing projects more quickly. Because of its water-based composition, cleaning is also straightforward and only needs soap and water rather than abrasive chemicals.

Sturdiness is yet another advantage. Even in severe weather, water-dispersion facade paint is meant to withstand chipping, peeling, and fading. This durability reduces the need for frequent repainting by preserving the visual appeal of your house over time. Additionally, a lot of formulations have anti-mold and anti- mildew qualities, which helps to prolong the life of your paint job.

But there are a few disadvantages to take into account. Although water-dispersion facade paint is more adaptable than oil-based counterparts, it might not stick to some surfaces as well. Older homes made of different materials or those that have previously been painted with oil-based paints may have problems with this. Furthermore, on porous surfaces, it might not offer the same level of coverage, possibly necessitating multiple coats and raising overall costs.

In conclusion, there are many benefits to using water-dispersion facade paint, including its superior durability, ease of application, and speedy drying times. However, it’s crucial to balance these advantages against possible adhesion problems and the requirement for extra coats on particular surfaces. You can decide if this kind of paint is the best choice for the outside of your house by taking these things into account.

Composition of facade water-dispersion paint

An emulsion of different solid polymers makes up the composition of this kind of paint. Most of these are polymers of the acrylic type. Water is the foundation of this material, but water does not remove it.

The component used for binding is the primary characteristic that sets it apart, and it is dependent on composition.

In light of this, the hues are:

• polyvinyl acetate (in other words, they are called PVA paints);
• latex;
• acrylic.

Advantages and disadvantages

Water-dispersion paint has several benefits, which we can enumerate, regardless of its application:

• complete safety and high level of environmental friendliness. This is explained by the fact that during the production of paint, the solvent is replaced with ordinary water;
• the material does not have an unpleasant odor;
• simple application technology;
• there is no need to have any special skills to paint the surface;
• apply the composition using a brush or roller;
• the material is not subject to ignition, which gives it a high level of fire safety;
• creates a breathable coating, which guarantees the inability of fungus and mold to develop on it;
• the service life of the surface is 15 years;
• throughout the entire period there is no peeling of paint, cracking or blistering;
• the drying speed of one layer is several hours;
• The coating created with water-dispersion paint is characterized by a high level of resistance and does not respond to mechanical damage;
• affordable pricing policy;
• it is characterized by high water resistance, this is especially important if painting is carried out on wood. The film created by the paint provides reliable protection;
• During production, it undergoes a series of tests, after which its quality is confirmed by a certificate.

There are a few minor drawbacks to these materials in addition to the listed benefits:

• Painting work is only allowed in good weather conditions. If it is raining or low air temperature outside, this will become an obstacle to water evaporation. Hot weather during construction activities is also unacceptable, as this causes the surface to dry out too quickly, which leads to deterioration in quality;
• requires preliminary surface preparation and its alignment.

In order to conceal surface imperfections, a smooth surface is necessary because the paint layer lacks the necessary thickness.

Specifications

A feature of water-dispersion paint is as follows:

1. Brightness and purity of whiteness thanks to the high quality titanium dioxide contained. Often, this type of material for facade finishing is produced in white.
2. You can create the desired shade using a special coloring pigment, however, the degree of saturation and brightness of the final result depends on how high-quality the base is, that is, the whiteness.
3. Coverage parameter, which affects the amount of material consumption. The ideal volume to weight ratio for paint is 1:1.5. If the density is lower, this indicates that the composition contains a large amount of water. If the density is greater, then the paint is present in the paint in excess. Either of these two options affects the hiding power for the worse.
4. High moisture resistance. This parameter determines the area in which the material can be used. Water-dispersion type of polyvinyl acetate composition is considered less moisture resistant. Other types can easily withstand the effects of any detergents.
5. Resistance to UV rays. Water-dispersion paint of polyvinyl acetate composition is able to remain unchanged for almost the entire service life. All compositions based on latex have good resistance to ultraviolet rays and are capable of fading.

How to choose correctly

Prior to making the purchase of water-dispersion paint for finishing work, it’s critical to ascertain the performance attributes that are essential for facade finishing. In any event, the material must possess the best quality indicators available in order to both create a decorative layer and shield the structure from harm.

The following considerations need to be made when buying paint:

• Country of manufacture;
• Trademark;
• Scope of application of the material;
• Availability of a quality certificate;
• Expiration date;
• Storage conditions;
• Packaging (usually 15 kg).

Acquiring materials without quality certificates is not advised because there is no assurance that the brand being bought will be able to supply the house with the specified list of specifications.

Application areas

The following circumstances allow the use of water-dispersion paints and varnishes:

1. The most popular area of ​​application for this type of material is finishing facades made of concrete, brick or plastered walls. Acrylic water-dispersion paint is used for this.
2. It is permissible to use this type of material to provide protection for building structures. Considering that elements made of concrete or reinforced concrete are exposed to rather aggressive conditions that lead to corrosion processes, coating with water-dispersion paint creates a protective barrier.
3. A reliable option to ensure a long-lasting high-quality layer of paintwork for bathroom, shower or sauna is the use of acrylic-based water-dispersion paint. Antiseptics are added to such compositions, which protect rooms with high levels of humidity from the appearance and development of fungus and mold.
4. Painting concrete floors. On an industrial scale, water-dispersion paint is used for such work, which is based on a water emulsion of epoxy oligomers. However, the use of this coating is limited in rooms characterized by high mechanical load on the floor.

Water-dispersion facade paint is a popular option for both do-it-yourselfers and professional painters because of its many advantages, including ease of application, quick drying times, and exceptional environmental safety. Nevertheless, it has disadvantages as well, such as weathering susceptibility and frequent maintenance requirements in harsh climates. Homeowners and builders can choose wisely whether this kind of paint is the best option for their projects by being aware of these benefits and drawbacks.

Painting technology

The following guidelines are followed during the painting process:

• The first step is to thoroughly mix the paint composition;
• If you are painting the surface for the first time, start applying a primer. If there is already any finishing material on the walls, then first remove it, after which the surface is primed. It is very important to ensure a perfectly smooth surface of the walls during priming;
• then give the main paint and varnish material the desired color. For this, special coloring pigments are used. To obtain a uniform color, each time after adding a small amount of pigment, the entire volume of paint is thoroughly mixed;

It is important to keep in mind that one container will probably not be sufficient to finish the entire facade; as a result, it is critical to determine the precise quantity of pigment added to a given volume of the primary paint.

• start working, starting with the window openings. Paint the first layer parallel to the window. You can use a brush or roller for application;
• after applying the first layer, you must wait at least 4 hours. This amount of time is needed for the paint to dry completely;
• the number of layers for application is allowed up to 3 pieces, it depends on the condition of the surface to be painted.

The paint consumption parameter is a crucial consideration when painting. It makes no difference whether a roller or brush is used for painting when using water-dispersed paint and varnish material. Per square meter, consumption ranges from 140 to 180 g.

It is advised that you wear safety glasses and apply a small amount of protective cream to your face before beginning any repair work that involves water-dispersed paints or varnishes.

Water-dispersion facade paint is a popular option among builders and homeowners because it has many benefits. Being environmentally friendly is one of its key advantages because it contains few volatile organic compounds (VOCs). This indicates that it is safer for the environment and the users. Water-dispersion paint also makes painting more convenient and time-efficient because it is simple to apply, dries quickly, and cleans up with just soap and water.

Water-dispersion facade paint also has the notable benefit of being weather-resistant and long-lasting. It creates a pliable, permeable layer that shields the surface from rain, UV rays, and temperature changes while allowing moisture to escape the wall. This contributes to a long-lasting and visually beautiful finish by preventing peeling, cracking, and fading.

There are, however, a few disadvantages to take into account. Compared to some other paint types, water-dispersion paint may be less abrasion resistant, which could be problematic for surfaces that are subject to physical wear and tear or high traffic areas. Furthermore, even though it functions well in most climates, it might not be the greatest option in very humid or wet areas where mold and mildew growth can be an issue.

In conclusion, water-dispersion facade paint is a flexible and green choice for a variety of exterior painting tasks. For homeowners wishing to improve and maintain the exterior of their home, its protective properties, speedy drying time, and ease of use make it a sensible option. To ascertain whether this kind of paint is the most appropriate for your needs, it is crucial to take into account the particular circumstances and specifications of your project.
