Why do you need to paint the facade
The external decorative protective layer of the external coating is applied through the coloring of the facade. Apart from its aesthetic effects, the multicolored layer forms a strong barrier that prevents the wall material from being penetrated by water, changes in temperature, and the growth of mold, fungus, or algae.
Furthermore, vapor permeability—the capacity to remove moisture from the inside at the capillary level without allowing absorption from the outside—is a crucial feature of facade coatings.
Paints with low vapor permeability are not meant to be used outdoors because steam builds up inside the walls and eventually freezes, expands, and tears the walls from the inside. Steam has no way to drain outside of the walls.
Consequently, the right paint choice is crucial because it affects the wall pie’s ability to function properly, the longevity of the materials and structures, and, last but not least, the finish’s aesthetic appeal.
Types of facade paints
Approximately the same structural makeup characterizes facade paints:
- Base (film former).
- Fillers.
- Pigments.
- Solvent.
According to the kind of paint base, there are:
- Mineral. The basis is derivatives of cement and lime, they are inexpensive materials.
- Silicate. Manufactured on the basis of liquid glass with additives. Have low water-repellent ability.
- Silicone. Expensive paints based on silicone resins. They have an excellent set of properties – high vapor permeability, completely impervious to water, very elastic. The reason for its rare use is the high cost of the material.
- Acrylic. One of the most common groups of paints, has good qualities and a relatively low price.
According to the kind of solvent:
- Water.
- Using organic solvents (white spirit, etc.).P.).
The material and operating characteristics of the wall, as well as the local climate and weather, influence the choice of paint type.
Water based paints
Paints that are water-based, or water-dispersed, are made by emulsifying tiny bits of the working mixture in water. Applying water results in a coating layer that, once dried, does not react negatively to the influence of water. The water is partially absorbed into the base and partially evaporates.
TThere are significant benefits to this composition:
- No smell. This is the main advantage of water-based materials, which often determines the choice of users.
- No high shine. The surface has either a deeply matte or soft silky sheen. Visually matte surfaces look smoother, do not glare and create a noble and stylish appearance of a house or cottage.
- Availability of excellent performance qualities of the coating. Almost all water-dispersed paints have a full set of properties that allow them to successfully perform their functions.
- Possibility of tinting in any color. All water-based compositions are available in the form of two or three types – bases. Usually the first one is white and can be used as an independent paint or tinted in some light shade. The second and third are transparent, intended for tinting into denser and brighter colors.
- Low consumption. Most water-based compositions have high hiding power and low (relatively) density, which allows you to cover a larger area than other types of paints.
- Fast drying. Unlike other types, water-based mixtures dry within a few hours, allowing for maximum speed of work.
- Plain water is used as a diluent, which makes work much easier (and cheaper) and helps keep working tools tidy and clean.
The following are the drawbacks of water-based paints:
- Contraindications for use on metal substrates.
- Weather restrictions, cannot be applied in rainy weather.
- The stains that appear are difficult to erase, and repeated washing of the walls spoils the appearance of the coating.
Although the use of water-dispersed facade paints is becoming more and more common, there are some minor drawbacks.
Organic based paints
Materials made of organic materials are more conventional since they have been around for a while. Because they don’t trust the seeming fragility of compositions containing water, a lot of users prefer them for this exact reason.
Paints with an organic base have several benefits.
- Coating strength.
- Elasticity, the ability to compensate for minor movements during shrinkage.
- Water resistance.
- Frost resistance.
- Vapor permeability.
- Compatible with most surfaces, excellent adhesion to metals.
- Tolerance of sudden temperature fluctuations.
- Durability.
- Possibility of painting at low temperatures or high humidity.
Among the drawbacks are:
- Pungent odor upon application and for some time after drying.
- Drying one layer requires a long time – two days, for subsequent layers the drying time increases.
- Requires the use of solvents, which increases costs.
Paints made with organic solvents shine highly. Different people have different opinions about this feature; while some find it highly desirable, others see it negatively.
Furthermore, the strong smell of organic solvent paints is a major drawback as it is highly intolerable and may cause nausea in certain individuals.
Due to this situation, these paints are less competitive when compared to water-based paints; however, the material’s other qualities are highly effective and enable the creation of a coating that is both durable and long-lasting.
How to choose façade paint for a specific surface?
- First of all, to choose the right outer covering, you should take into account the base material. Most façade coatings specialize in concrete (including.h. after insulating the walls with polystyrene foam), brick, aerated concrete and plasters of various compositions. At the same time, water-based paints are not always suitable for wooden surfaces and are completely unsuitable for application to metal (steel) substrates, which is the main difference from paints based on organic solvents, which serve as reliable protection for such substrates.
- The second selection factor is surface quality. The presence of shine and the color of the walls directly depend on the composition of the paint used for exterior decoration. Water-based mixtures have lighter tones and a predominantly matte surface, while organic-based materials make it possible to obtain coatings with a hard shine in dense tones, and the choice of color and its tonality is much wider than that of water-based paints.
- Wherein, We must not forget about the operating conditions of the building — in areas with high levels of air pollution from various industrial or other substances, dust or the presence of large amounts of exhaust gases (industrial or close to large highways) Highly water-repellent paints should be used, allowing you to painlessly endure periodic cleaning of walls. For regions with frequent rains, this choice is also relevant, since the penetration of rainwater into the wall material threatens their destruction.
Which façade paint is most optimal??
The material that has been chosen optimally must best meet all operational and climatic requirements. Furthermore, the coating’s aesthetic qualities are significant because they are primarily evaluated when a freshly painted house is in view.
Water-dispersed formulations have become more and more popular recently, which makes sense given their characteristics. The most significant of these is the lack of smell.
The ability to remove paint stains with ordinary water is also crucial; this is a benefit because solvents can also remove the necessary substances, which could damage items that have been inadvertently painted.
Preparing the wall surface for painting
A wall surface that is dry and clean is necessary for painting.
To get ready, you’ll need:
- Disconnect all hanging structures — brackets, canopies, lanterns, air conditioners, etc.P.
- Remove trim from windows or doorways.
- Inspect the walls, determine the degree of wear of plaster or other materials.
- Detected defects are puttied; in case of large quantities of peeling or shedding, it is recommended to apply a leveling plaster layer.
- Some types of facade paints require preliminary priming.
Before painting, freshly applied cement or lime plaster needs to sit for at least four weeks to allow the chemical processes in the plaster to finish and the layer to crystallize.
Facade painting technology
It is dry and windless when painting is done.
The ideal temperature of the air is:
- For water-based paints – from +5° to +30°.
- For compositions based on organic solvents, the temperature range expands to the lower side (there are brands of paints that allow use down to -20°), but due to the strong odor, use in hot weather is difficult.
Paint is applied manually with brushes or rollers, or mechanically with a spray gun, air, or airless spray.
To prevent potential blunders, carefully read the application procedure and additional working conditions before applying paint.
Depending on the type of paint, there may be work interruptions (for paints based on organic solvents) or the surface must be completely covered in one sitting (primarily for water-based coatings, as the edges of various layers are easily visible).
Typically, two coats of paint are applied to the surface, with a 16–24 hour gap between each coat.
Tips for caring for painted surfaces
The façade coverings require very little maintenance. Other than the occasional hosing to clear the dust, no action is necessary.
The quality and properties of the coating fully satisfy all requirements and do not necessitate the use of any protective compounds or other actions aimed at improving the condition of the coating.
Facade paints serve the same purpose regardless of their wide range and variety of types. The difference in properties, which consists only of a few positions, is not critical because they are specifically made for this purpose.
In addition to providing excellent wall protection from external factors and creating a stylish and neat appearance, water-based paints and materials based on organic solvents can fully satisfy all requests.
