Concrete coatings must be qualitatively protected from negative environmental factors, as well as to give them the properties of increased resistance to pollution. These are the requirements that concrete paint for outdoor use should meet. The composition should guarantee the buildings not only a beautiful appearance, but also a sufficiently long term of operation.
Concrete paint for outdoor use is simply required to 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 concrete paint for outdoor work must have must be strength, which helps prevent its peeling.
So, the following requirements are imposed on 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 conducting work;
- not only the attractiveness of the resulting coating, but also the absence of spots, stains, and other defects depends on how saturated the glossy layer will be;
- such an indicator as abrasion resistance is important, which ensures durability;
- paint on concrete for outdoor use should provide protection for the reinforced coating from corrosion; to avoid leaching, it is worthwhile to apply the composition a month after the final hardening of the surface;
- the presence of antibacterial components in the composition serves as a guaranteed protection against the nucleation of mold and heterogeneous fungi.
Paint for concrete for outdoor use should also have other equally important characteristics, such as moisture resistance, resistance to weathering, resistance to mechanical and chemical influences, thixotropy, flowability, drying speed, environmental friendliness. The composition of the paint usually includes many components that allow for adhesion, color, texture, as well as special properties. Depending on the binder taken as a basis, it is possible to classify a family of paints: polyurethane resins, drying oils, limes, polyacrylates, etc. Previously, vinyl products were especially in demand, but today the leadership belongs to acrylics. 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. Polymer paint for concrete has important properties that allow you to use it in any external circumstances.
It is worth saying that the most stringent standards for these products apply in the United States, therefore, paint and varnish products of their production are considered the safest in the world.
