The foundation of a building constantly suffers from negative external environmental factors. Not immediately, gradually, but the strength of the outer layer of materials decreases, they slowly decay, become even more pliable to harmful influences. One of the means to resist this - paint for the base of the foundation.
is adversely affected by not only the underground part of the building - it is usually immediately protected by waterproofing, but also the elevated lower part, which often remains without finishing, facing for a long time, having time to decay. Here are some of the main advantages of using paint to finish the base:
The materials used - concrete or brick, are strong enough, but water with temperature drops can destroy them quite quickly. The coloration will close the external pores of the materials from moisture penetration.
A good paint will remove moisture, but it will allow air to pass through. With this protection, the wall material will "breathe" and will not damp.
The foundation will become more visible, tidier and more respectable, since the deficiencies will disappear.
Painting the basement of the house is an alternative to a more expensive finish, adding attractiveness, aesthetics to the exterior, and protection from the aggressive action of the environment, slowing down the aging process of materials.
Important! For work, you must purchase only waterproof materials.
Long-term service warranty paints - compliance with requirements, workmanship, compliance with application technologies. Higher performance requirements are always applied to exterior building materials.
Adhesion to the bases . Microparticles are present on the surface of the concrete, which significantly reduce adhesion, creating film stresses, prerequisites for flaking. The coating must penetrate deeply inside, for this purpose the paint is used together with priming compositions.
Resistance to high humidity . Constantly high humidity of concrete shortens the service life, therefore materials are selected only for facade works, supplied with special additives, additives.
Low abrasion, high strength . Paints must withstand mechanical impact and contact with objects without critical consequences.
Light Resistance . It is assumed that the paint will be affected not only by ultraviolet rays, which destroy intermolecular bonds (at the same time, the paint cracks and peels off under the influence of minor loads), but also infrared rays that change the original color and promote fading of the paint. Used mineral dyes prevent these effects.
Good vapor permeability . The paint-and-lacquer layer should not seal the surface of the base, without interfering with the release of excess moisture, otherwise it accumulates between them, and during freezing-thawing cycles provoking the destruction of paint and concrete. It is better to avoid painting the base with oil paints, which create a hermetic layer after drying.
Pollution resistance . Of course, the criterion is applicable to the paint itself, but still it relates more to the quality of surface preparation. Smooth surfaces accumulate less dirt - a nutrient medium for vegetation, they are easier to sweep and wash, and the base - the lower part of the house, where most of the dust settles.
Drying time of the surface to peel off and to full strength. Atmospheric precipitation adversely affects the immature film, so time plays a key role.
Moderate consumption . This is an important property for all paints, but for concrete surfaces it is especially important, since it is usually significant areas, and high-quality surface painting involves at least two stages.
Manufacturability . That is, high-quality staining is possible with a professional tool, or in any way possible.
Color saturation . Even the first layer should overlap the color of the concrete, it lowers the flow rate, increases the visual appeal.
Value for money . The choice of coverage undoubtedly affects the overall estimate of construction work. The cost of paint depends on the composition of its components. There is either price or quality.

Work begins after surface preparation - scraping off delaminations, embedding cracks, irregularities, necessary leveling.
The preparatory stage for painting is priming, it is obligatory for execution, it is carried out for better adhesion of paint to the surface, it will provide a more uniform coloring, in other words, it will noticeably improve the quality of coloring. Manufacturers have proposed a rich choice of multifunctional facade primers, impregnations for porous materials are provided, thanks to which moisture absorption is reduced, water resistance is increased.
Paint coats diluted with water or organic solvents are made to paint the foundation. The instructions are always recommended to acquire the appropriate, suitable to a certain type of paint primer.

Traditionally, paint for a foundation for concrete is chosen from a line of well-proven facade decoration materials. The range is quite wide and provides the possibility of high-quality color, taking into account the specific operating conditions.
Acrylic compositions for facade work are applicable for painting concrete, brick, stone surfaces. Aqueous solution of acrylic resins and polymers, the concentration of components sets the glossy or matte result. The coating is durable, wear-resistant, with a high degree of protection of painted surfaces from precipitation, chemicals, mold and mildew. Painted materials become moisture-resistant, but remain vapor-permeable, frost-resistant, and retain a rich original color for a long time. They require careful preparation of the painted surface, but are easy to apply with hand tools, and are distinguished by their economical consumption.
Alkyd Paints , in the composition of which the mineral crumb on the binder - alkyd resins, after dyeing, will polymerize into a smooth, elastic protective film. Demanding to comply with the technology of application, the longevity of the coating directly depends on it. Presents a glossy, semi-matte, matte options, but for concrete manufacturers recommend a glossy look - much longer service life.
Polyurethane paints in one-component and two-component versions. Form resistant to abrasion, weathering, visually attractive glossy films. Hardening time two days, full strength is reached in 14 days.
Silicone paints are an option for painting highly porous surfaces, therefore they are suitable not only for fresh, but also for the restoration of rather dilapidated, protection of old surfaces.
In the category of innovative coatings, you can highlight rubber paints on acrylic water dispersion base, having a reputation for reliable, durable coating with good performance properties. It is applied like any paint, polymerized into an elastic, durable film similar to rubber. The following components are used for production:
Individually designed acrylate latex , giving the coating strength and elasticity, coalescent, contributing to film formation.
Fillers, additives and reagents , which increase the performance characteristics of the material and paint it.
Antifreeze responsible for frost-resistant properties.
Preservative , to increase the shelf life under the condition of a closed container, preventing the appearance of fungi, mold.
Solvent is water, about 5% by volume.
All ingredients are safe for the environment and humans during application and during operation. The composition allowed to obtain additional performance properties:
Improved adhesion .
Resistance to ultraviolet radiation , changes in temperature, humidity, atmospheric influences.
Water vapor permeability of the coating, it prevents the accumulation of condensate, prevents the growth of microorganisms.
Duration drying 1-2 hours.
Easy application of - with a spray gun, brush, roller, however, it is necessary to apply several thin layers instead of one thick one.
Wear resistance , durability, elasticity and ability to stretch.

Many paints for protecting and decorating the base have similar characteristics. Having understood in detail how to paint the foundation of the house outside, responsibly approaching the acquisition of materials and doing the work with high quality, one can expect that it will not have to be repaired soon.
