How to choose a facade paint for outdoor use?

There is more than one option for ennobling the facade of a building. To give it a beautiful look, they use ventilated facade panels, siding, cover it with natural or artificial stone and plaster it. Plastering is a common option for finishing the exterior of a building due to its low cost. But with all this, such a house will not look bright and impressive enough and will not have a finished look. Special facade paints will help to solve this problem.

The modern paint market is represented by a huge assortment, there was also a place for facade paints. The most common are such dye mixtures as acrylic, silicate, silicone, latex and textured.

Acrylic is the most popular and inexpensive option for painting outside walls. Interacts with almost all materials from which a building can be erected. After drying, it creates a durable protective film that protects against environmental influences. Does not fade, is abrasion resistant and does not crack. These paints are not suitable for lime plaster and sandstone walls.

For such surfaces, silicate paint is more suitable. It is produced on the basis of silicate glue, to which mineral pigments and fillers are added. The service life of this type of glue is 25 years. It is waterproof and gives a secure grip on the material to which it is applied. Resistant to any atmospheric influences. This mixture is suitable for use on concrete and brick. Its weak side is that it is susceptible to mechanical stress and is not elastic enough, therefore, it may crack after drying.

Silicone paints are considered one of the best for painting plastered facades. In terms of their characteristics in terms of elasticity, resistance to mechanical damage and prices, they lag behind acrylic compounds, and that is why they have not received such widespread use. After applying this type of paint, the plastered surface does not absorb moisture, but has a high level of vapor permeability and is resistant to temperature extremes. Once dry, the coating is dust-repellent and not exposed to sunlight.

Latex or water-dispersion mixtures are made on the basis of polymer components. The combination of latex and acrylic has made it possible to increase the operational capabilities of the formulations and increase the scope of their application. They can be used for exterior and interior decoration, but the surface should be well primed before application to avoid further growth of mold and mildew. Any type of surface can be painted with this composition. It does not have a pungent smell, is environmentally friendly, air-permeable and fireproof. Water-based paints can be diluted with water. They dry quickly and are resistant to moisture. The only drawback is that there is no way to tint them in bright and saturated colors.

Textured or textured coloring compositions are suitable for creating decorative coatings not only on the facades, but also on other building elements. They do not require careful surface preparation and can be applied to cracks and chips at corners.The composition of the paints contains special plasticizers that help to create a unique protruding pattern. The composition is highly frost-resistant, resistant to ultraviolet rays, insensitive to moisture, dust and dirt-repellent properties. Does not crack due to its high ductility. It can be applied to any surface - both brick and wood.

In addition to the above, there are still cement and cement-lime mixtures, but due to some shortcomings in production, they are of little demand, since they have poor moisture permeability, a simple color scheme and insufficient bactericidal protection. After application, fungi and mold often appear on them.

The main advantage of painting the plaster from the outside is that the paint enhances its strength and gives a finished look to the facade. It retains dampness, the walls get wet and deteriorate to a lesser extent. Prevents the ingress of various microorganisms on the surface of the plaster, which means that the service life of the building is increased. Due to the fact that the paint is hygroscopic, the walls do not accumulate condensation, which forms from the difference between the internal and external temperature conditions. The paint is weakly susceptible to various kinds of atmospheric influences.

To get a solid and beautiful coating that will last at least 10 years, it is necessary to take a responsible approach to the choice of the coloring composition. Many do not know how to properly approach this issue.

The first thing to pay attention to is the type of surfaceto be painted. For each material, there is a specific paint, endowed with characteristic properties. For a brick facade, a coloring composition for a mineral surface is suitable. The coloring composition for concrete is characterized by high porosity and resistance to alkaline media. It consists of acryl-silicone and water-dispersion elements. It is not easy to find paint for wood. Such a surface most of all absorbs dampness, rots quickly and easily ignites. For plastered facades, a vapor-permeable and moisture-resistant paint composition is suitable.

There is no need to chase cheapness.

Expired paint will have poor quality, so you will not receive the required protection.

Do not forget that before starting work, the surface needs to be thoroughly cleaned and primed. Be sure to pay attention to the compatibility of the purchased paint and primer. Calculate the consumption per m2.

The coloring composition must certainly have the following indicators:

• Differ in resistance to mechanical damage.
• Protect from direct sunlight.
• Exclude the development of microorganisms, fungi and mold.
• Resist exposure to chemicals.
• Fire safety.
• Sufficient elasticity to prevent cracking.

Some formulations also have an antistatic effect. These paints should be used on roadside facades.

Emphasize your choice of glossy and matte paints. Glossy ones attract with expressive colors and shimmer in sunlight. But they are designed to be applied on perfectly smooth surfaces and are able to highlight all defects on them. On the contrary, matte paints hide flaws.

An important aspect when choosing a paint is the manufacturer. In the midst of today's abundance, it's easy to get lost and get confused about brands. Leading places in the rating are occupied by such companies as the German Alpina and Cerezit, the Finnish Tikkurila and the English Dulux. The products of these companies have rightfully earned the trust of many buyers and are in high demand among consumers.

It is preferable to carry out painting work on painting the facade in the spring or postpone this process until the fall. The temperature regime at this time is in a stable state and solar activity is low.

Preparatory work takes place in several stages. First, assess the condition of the surface. If the plaster or paint on the base is old and begins to crack and crumble, then it is necessary to remove them and plaster the wall again. If the surface is in good shape, then tap it lightly with a hammer, looking for weak points. If found, these fragments are removed and repaired. Then apply the deep soak primer twice and let it dry thoroughly. If necessary, antifungal or antibacterial agents can be additionally applied for protection.

It is imperative to calculate the required amount of material. For this, the area to be painted is calculated. Then the resulting number is multiplied by the average consumption rate (it is indicated on each container) for the first, and then for the second layer. Almost all facade paints are applied in several layers.

And, finally, it is imperative to prepare the necessary materials at hand. In the process of painting, scaffolding or a ladder, a roller, a brush, paint and a container for it, a mixer and a drill, gloves and glasses will come in handy.

Facade paints are the best way to ennoble your home and give it a complete and magnificent appearance. And the range of modern coatings is so rich that it will allow you to make a choice for every taste and budget.
