Technical characteristics of facade water -based paint

Choosing the correct paint is essential for preserving the integrity and beauty of the exterior of your home. Because of its many benefits, water-based facade paint has gained popularity among professionals and homeowners alike. This kind of paint is perfect for protecting and enhancing the exterior of your home because it is made to withstand the harsh conditions that exterior surfaces frequently encounter.

Water-based paint for the facade provides exceptional longevity, withstanding peeling, cracking, and fading over time. In order to avoid damage brought on by trapped moisture, it offers a breathable layer that lets moisture escape from the building materials. These paints are also renowned for their rapid drying times, which greatly expedites the painting process.

The environmental friendliness of water-based paints is one of their best qualities. They release fewer volatile organic compounds (VOCs) than solvent-based paints, which makes them safer for the environment and the people using them. Because of this, water-based facade paint is a great option for people who want to lessen their environmental impact.

The technical aspects of facade water-based paint, including adhesion, weather resistance, color retention, and more, will be thoroughly examined in this article. Knowing these characteristics will enable you to choose the appropriate paint for the exterior of your house with confidence, assuring both long-lasting protection and visual appeal.

Features of water -based facade paint

Unlike all other facade paints, the water-based paint can be diluted with regular water.

Following drying, a typical film is created that is water-insoluble and fully conforms with all facade coating specifications:

• Moisture resistance.
• Vapor permeability.
• Elasticity.
• Sunny resistance, ability to maintain your color throughout the entire service life.

A matte coating with outstanding aesthetic qualities is produced after applying water-based facade compositions; the surface does not glance, and any existing bumps—especially when textured plaster is used—do not give the impression of having "rowan in the eyes."

In addition, finishing relief surfaces with two or more colors produces a variety of intriguing effects that can only be achieved with facade paint.

Vapor permeability and elasticity are significant markers. Small cracks may appear as a result of soil shrinkage or seasonal movements; in this situation, the paint film’s quality helps to minimize the number of cracks.

Water vapor is removed from wall materials with the aid of vapor permeability. If this characteristic is lacking, the material will "bar" vapors and the coating will peel.

Water-based facade coatings for outdoor use are typically sold as semi-finished products, which are white bases that can be tinted to any desired shade.

This eliminates the need to waste time looking for the ideal solution and allows for the independent acquisition of the mixture’s desired color and tone.

The same processes are used to produce water-based facade paints as any other type:

• Acrylic. The most common group of facade paints, produced on the basis of acrylic resins with pigment additives. The most successful combination of price and quality of acrylic facade paints brought them to the forefront of finishing materials.
• Silicate. The basis of such paints is pigmented potassium liquid glass, which increases the strength of the coating. Has excellent performance, long service life.
• Silicone. They have increased elasticity and have pronounced water-repellent properties. At the same time, silicone paints are the most expensive, so their use is not accessible to everyone. This circumstance reduces interest in the material, although in terms of durability and surface quality such paints fully justify their price.

Advantages and disadvantages

Facade paint with a water base has the following benefits:

• No pungent odors typical for paints during application.
• High vapor permeability of the coating.
• Simplicity and ease of application, matte surface looks great even when applied by an untrained person.
• Small consumption. Water-based compositions are several times more economical than other types.
• Long service life of the coating.

The drawbacks of paints with water content:

• Some color change after drying (often the white coating darkens a little).
• Do not work in bad weather – the paint will wash off in the rain.

Specifications

Technical attributes serve as this composition’s sort of passport, showcasing its attributes and limitations. It would be absurd to list the many technical differences amongst the water-based coating samples available on the market.

Rather, let us examine the standard parameters, their definitions, and their implications:

• Binder. This is the basis of the material; it usually acts as a binder acrylic, silicone or liquid glass. You should pay attention to the percentage composition; it is usually not indicated on the packaging of low-quality materials. The amount of film former for water-dispersed compositions should be 50-60%.
• Water permeability. An important parameter, usually on the label denoted by the letter W. The lower the W value, the less moisture the coating absorbs and the better it protects against water (for example, W = 0.05).
• Density. An indicator that gives an idea of ​​the hiding power of the material – ability to apply non-transparent coating in one go. High-quality paint has, on average, 1.5 kg/l.
• Area of ​​application, application conditions, etc.d. All these parameters determine the most effective areas for using the material, the type of application and other technological aspects that ensure the most successful use.
• Price, manufacturer. This data helps you understand how well the paint corresponds to the declared qualities, since more reputable manufacturers sell the product more expensively, but fully guarantee the quality corresponds to the passport data. Certified products automatically have all the necessary parameters, it cannot be otherwise.

You must rely on the information on the label because there is no way to independently confirm that the paint parameters match the declared values. We have the chance to greatly lower the risk of buying inferior material by selecting certified products.

Main types and manufacturers

Both domestically and internationally, there is a large industry dedicated to producing water-based facade paints.

We can mention the following Russian manufacturers:

From international businesses:

• Tikkurila.
• Dulux.
• Caparol.
• Dufa
• Beckers and many others.

Listing the producers of facade water-based coatings alone won’t help anything, especially since the selection is always changing and new businesses are always entering the market to sell their wares.

As a result, the best course of action is to choose the most appropriate option after determining which paint type will work best for your particular situation (house finishing material, local climate, and other site features).

Water-based facade paint is an economical and adaptable option for exterior house renovations that combines long-lasting protection with ease of application. This kind of paint is well-known for its short drying time, minimal environmental effect, and superior weather resistance, which makes it perfect for preserving and boosting the visual appeal of home facades. Water-based paint ensures the longevity and durability of the external surfaces while offering the flexibility to achieve the desired look in a variety of colors and finishes.

Paint consumption per 1 m2

Paint that is based on water is a cheap material. Compared to other coating types, application consumption is significantly lower, but quality indicators remain unchanged. The consumption varies according to the kind of base and the paint’s initial density.

• First layer – 0.25-0.60 kg/sq.m.m.
• Second layer – 0.15-0.40 kg/sq.m.m.

The precise consumption should be determined for each type of material on the packaging separately, not just based on average data. Because production testing and on-site work are conducted under different conditions, the manufacturer’s stated consumption is actually somewhat higher.

What surfaces is it suitable for?

Paint with a water base Perfect for all surfaces, save metal ones. The truth is that the presence of water induces corrosive processes that can damage the wall’s appearance. These processes are evident when red, rusty spots appear on the coating. You should select the proper materials for metal parts.

Plaster presents another drawback for water-based paints. No sooner than two weeks after plaster application (a month, according to some experts) may the final water-based coating be applied.

This is because you have to wait for the reaction to finish since alkali-containing materials and carbon dioxide actively participate in the plaster’s crystallization process.

Water-based paints for facades are generally appropriate for finishing:

• Concrete walls.
• All types of plaster.
• Stone, brick.
• Wooden walls and structures.
• Previously painted surfaces.

Water-based façade coatings should be taken into consideration as universal finishing materials due to the wide range of options available.

Water-based facade paint is a practical and adaptable option for improving the exterior appearance and longevity of a building. Its primary benefit is that it dries quickly and is easy to apply, which expedites and reduces the amount of time needed for painting. Additionally, the paint is environmentally friendly, as it contains fewer harmful chemicals compared to traditional solvent-based paints.

Another important advantage of water-based paint is its durability. Its exceptional resistance to moisture, UV rays, and weathering guarantees that the facade will look brand-new for many years to come. Additionally, this kind of paint is flexible, which is essential for preserving the external integrity of the building since it can expand and contract in response to temperature changes without peeling or cracking.

An additional notable feature is the extensive selection of colors and finishes. A wide range of shades are available for homeowners and builders to select from, so they can match their aesthetic tastes. Additionally, the paint is simple to maintain—just wash it with water. Furthermore, its breathability promotes a healthier living environment by halting the growth of mold and mildew.

All things considered, facade water-based paint is a great option for people who want to protect and enhance their buildings since it blends practical advantages with visual appeal. Its long-lasting performance, environmental benefits, and user-friendliness guarantee that it will always be a popular choice for both residential and commercial building projects.
