Technical characteristics of acrylic facade paint for exterior use

Popular for outdoor use, acrylic facade paint is renowned for its vibrant finish and longevity. Because of its ability to tolerate a wide range of weather conditions, this kind of paint is perfect for both protecting and enhancing the exteriors of buildings. Both professionals and homeowners value its adaptability and simplicity of use.

The outstanding adherence of acrylic facade paint to various surfaces is one of its primary benefits. Painting concrete, brick, metal, or wood all benefit from the robust bond that acrylic paint creates, which keeps the paint from chipping or peeling over time. This guarantees that your external walls will continue to look great for many years to come.

Another benefit of acrylic paints is their rapid drying times. As a result, projects can be finished more quickly, saving money and labor overall. Furthermore, compared to oil-based paints, they are more environmentally friendly and simpler to clean up because they are water-based.

The ability of acrylic facade paint to withstand UV radiation is another important quality. This lessens the fading and discoloration brought on by extended sun exposure. Consequently, buildings coated in acrylic paint keep their vivid hue, contributing to their curb appeal and preservation of value.

Acrylic facade paint is renowned for its flexibility as well. This characteristic keeps it from cracking and sustaining damage that more rigid paints can cause by allowing it to expand and contract in response to temperature changes. Because of this, it is particularly appropriate for areas with large seasonal variations.

Features of facade acrylic paint

The material is made up of acrylic acid derivatives in the form of resins mixed with different additives (like coalescent, latex, and defoamer), which determine the product’s composition and properties.

As a result, mixtures with excellent elasticity, frost resistance, durability, and other performance characteristics that are required for superior coating are produced.

There are mixtures of water-emulsion (water-dispersed) and organic solvents, which form two groups with similar properties but different types of diluents and handling ease.

Water-based acrylic compositions are more practical for finishing houses because they dissolve easily in regular water and don’t smell strongly, making it easy, affordable, and efficient to clean tools and maintain perfect order.

Advantages and disadvantages

Acrylic paints work well for both indoor and outdoor applications. Their popularity and wide distribution among finishers suggest that the material properties have been successfully combined.

Among the benefits are:

• Strength. The coating after drying is not so easy to scrape off even with sandpaper.
• Elasticity. A layer of paint holds up minor surface deformations well.
• Sun resistance. The surface does not fade during its entire service life.
• Dries quickly.
• Has high hiding power.
• High vapor permeability, waterproof.
• Large operating temperature range.

Among the drawbacks are:

• The need to carefully monitor the safety of material in open (started) containers.
• Some types cannot be applied directly to concrete; a preliminary primer is required..
• The materials are relatively expensive, and there is a need for preliminary tinting, which also requires expenses.

Acrylic paints are the most popular category on the market, which speaks volumes about the high demand for this material despite all of its drawbacks.

Because acrylic facade paint is weather resistant, long-lasting, and simple to apply, it’s a popular option for exterior use. This kind of paint creates a flexible, weather-resistant layer that is resistant to UV rays, rain, and temperature changes. Furthermore, acrylic paint is renowned for its ability to retain brilliant colors and breathe, both of which help to keep the building’s structural integrity intact by preventing moisture buildup. Professional painters and do-it-yourselfers will find it to be a convenient option due to its quick drying time and simple water cleanup.

Main types and manufacturers of acrylic paint

The quality of gloss, the solvent used, the material’s application area, and other factors all affect how different acrylic paints turn out.

The majority of finishers and consumers are satisfied with the high quality of the coating, which contributes to its wide range of offerings, which include a variety of materials with varying finishing specializations.

Consequently, water-dispersed latex compositions are deeply matte and have maximum vapor permeability, which is highly valuable for external coatings; latex compositions with a soft sheen also have increased water-repellent qualities.

The majority of samples are created as a foundation for tinting; while this makes it easy to achieve the right shade, it necessitates preparation before use.

Certain materials employ water as a solvent; once they dry, they become completely impervious to water and can only be extracted mechanically.

There are also compositions based on organic solvents, but because of their strong smell, they are not as practical to use.

The most well-known producers are:

The fact that there are many manufacturers and that this number is still rising shows how promising the industry is and how much demand there is for acrylic paints.

Brand Akrial – advantages, technical characteristics

Façade paints for use on brick, plaster, concrete, etc. are available under the Akrial brand.P. Possesses a potent combination of performance traits:

• Application at a temperature not lower than -15°, or not higher than +35°.
• High frost resistance of the coating.
• Drying time – 10 hours (at a temperature of +20°).
• Packaging: 12 or 25 kg bucket.
• The basis of the material is acrylic resin.
• Dry residue – 70%.

These qualities are not unique; rather, they match those of all the most well-liked acrylic products from reputable producers. However, Akrial products are significantly less expensive, which helps to advertise them in the marketplace.

Acrylic paint consumption per 1 m2

Consumption of acrylic paint is variable. It is dependent upon various factors such as paint density, surface type, base type, and material absorption capacity.

As a result, it is just not possible to specify the precise value for every product. However, based on the typical level of porosity and roughness, an average value can be used for medium density paint at a working temperature of 20°.

Under these circumstances, the consumption limits are 0.3 to 0.45 kg/sq.m. Although this value is significantly higher than the average that is generally accepted (0.17–0.2 kg/sq.m.), it is validated in practice because factory laboratory data does not accurately reflect the conditions of construction sites.

The value provided is merely an estimate for informational purposes. You should use the technical specifications of the paint type used for precise computations.

For what surfaces is acrylic paint suitable

The following surfaces are ideal for using acrylic paints:

• Concrete.
• Cement plaster.
• Cement-lime plaster.
• Lime plaster.
• Mineral decorative (textured) plaster.
• Acrylic plaster.

On these types of surfaces, acrylic paints work best and let you take full advantage of the coating’s advantageous properties.

Simultaneously, you should find out if the paint you are buying is resistant to alkali, particularly if it is from a lesser-known company. These companies frequently cut corners with their products, depriving them of many functional qualities.

Buying certified products from reliable manufacturers would be the best way to avoid such situations.

Facade painting technology

1. Before applying paint directly, you should prepare the surface. The base should not have dirty or greasy stains, efflorescence or limescale, residues of peeling paint or plaster, unused fasteners and other parts that make painting difficult. All surface deficiencies should be sparkled, crumbling or exfoliating areas – delete. To seal, use mineral putty for external use.
2. Work should be done in dry weather. The recommended air temperature is ot +5 ° up to +30 ° (in fact, at negative temperatures or exhausting heat, it is unlikely that anyone comes to mind to paint the house).
3. Building forests are usually hung with a net to protect against direct sunlight and the effects of wind that lifts dust.
4. Before applying, white paint must be tinted with special pastes. If the procedure is carried out independently, it is necessary to carefully monitor the accuracy of the dosage, since the slightest errors lead to the difference in the shade of the coating.
5. Before use, the paint must be thoroughly mixed in the factory container. An open container should be covered, the edges must be cleaned of paint, otherwise the lid will stick (acrylic paint has strong adhesive properties). To obtain the required viscosity, the material is diluted with an appropriate solvent or water.
6. At least two layers are used, the first of which serves as a base coat, and the second, more fluid, is an additional finishing coat. If it is necessary to apply three or more layers (rarely, but this happens), then each subsequent one should be made slightly less viscous to obtain a uniform surface.
7. Painting is carried out using the "wet on wet" method, that is, it is not allowed to leave uncoated areas on one plane. The boundaries of the areas covered at one time are located along the corner edges or decorative elements that intersect the entire surface of the wall.
8. Paint is applied either mechanically – with a spray gun, or manually – with a roller or brush. A spray gun is convenient for large areas and wall heights, but it is not always available, so you often have to make do with a roller or, which is a little slower and not so neat, a brush. Basically, a roller is used, and a brush is used only for fine finishing of edges (especially with a two-color coating) or around protruding elements, window openings, etc.d.

For external surfaces, acrylic facade paint is a flexible and long-lasting option. Even in severe weather, its superior adhesion guarantees a finish that lasts for a long time and doesn’t peel or crack. This makes it perfect for many surfaces, such as metal, wood, stucco, and concrete.

Breathability is one of the best qualities of acrylic facade paint. It stops the growth of mold and mildew by allowing moisture to escape from the building materials. This is particularly crucial in regions that experience a lot of humidity or rain frequently.

Its retention of color is an additional important benefit. Because acrylic paints are UV resistant, their brilliant color retention lasts for many years. This guarantees that your building or home’s exterior will remain attractive and new-looking for extended periods of time without requiring frequent repainting.

Acrylic facade paint is also simple to use. Because it dries quickly, projects can be finished more quickly. Applying it with brushes, rollers, or spray equipment offers versatility based on the size and nature of the surface to be painted.

In conclusion, acrylic facade paint offers a combination of breathability, color retention, durability, and application ease. Because of these qualities, it’s the best option for enhancing and safeguarding external surfaces, guaranteeing a long-lasting, high-quality finish.
