What should be the paint for concrete for outdoor use
Concrete pavements must be protected from negative environmental factors with high quality, as well as to give them the properties of increased resistance to pollution. It is these requirements that paint on concrete for outdoor use must meet. The composition should guarantee the structures not only a beautiful appearance, but also a sufficiently long service life.
Paint on concrete for outdoor use simply must meet certain requirements. It is worth saying that at the moment there are no universal coatings. Different products have different purposes, composition, application technology, as well as consumer properties. The main quality that paint on concrete for outdoor use must necessarily have is strength, which helps prevent its peeling.
So, the following requirements are imposed on the compositions of this kind:
The temperature range in which the coating is able to demonstrate its best qualities is very important, which should be taken into account when carrying out work;
Not only the attractiveness of the resulting coating, but also the absence of stains, streaks, and other defects depends on how saturated the glossy layer is;
An important indicator is abrasion resistance, which allows to ensure durability;
Paint for concrete for outdoor use should protect the reinforced coating from corrosion; to avoid leaching, it is worth applying the composition one month after the final hardening of the surface;
Guaranteed protection against the emergence of mold and heterogeneous fungi is the presence of antibacterial components in the composition.
Paint for concrete for outdoor use must also have other equally important characteristics, such as moisture resistance, weather resistance, resistance to mechanical and chemical influences, thixotropy, spreadability, drying speed, environmental friendliness. The composition of the paint usually includes many components that allow for adhesion, color, consistency, as well as special properties. Depending on the binder taken as a basis, it is possible to classify the family of resins, drying oils, lime, polyacrylates, and so on. Previously, vinyl products were especially in demand, and today the leadership belongs to acrylic paints. Most often, facades are treated with latex-based acrylic paint, which makes it possible to tighten microcracks, withstand significant temperature changes, and maintain its structure under continuous exposure to external factors. for concrete has important properties that allow it to be used under any external circumstances.
It is worth saying that the most stringent standards for these products are in the United States, so their paintwork products are considered to be the safest in the world.
