Facade paint is a resistant coating for beautifying the exterior of residential, office, factories, etc., which increases the life of the materials and adds to the beauty of the structure due to its waterproof and anti-erosion properties. The formulation of exterior paint is different from the interior paint. The color formulation of the outer wall of the building should be prepared according to the weather conditions of the region.
Usually, the coatings that include color are applied on fresh cement surfaces that still have carbon dioxide gas, not to mention that their cement component is very alkaline, therefore, polymer dispersions that are suitable for these colored coatings must be resistant to alkalinity and have good resistance to saponification. The lack of bond resistance against the mentioned features causes cracking, plastering, or loss of adhesion and finally reducing the lifespan of the facade. The good features of Rang Nama have made this type of exterior covering in a wide and complete range of areas with different climate characteristics, hot and dry, cold, moderate and humid, especially in big cities and industrial areas that have a large population and density and a high level of pollution. are being used. If we want to talk about the application of facade paint, it should be said that this coating is used to protect wooden surfaces, concrete and other materials, especially in the facade of buildings, which of course also has a decorative aspect. The lining that is suggested for work is: Epoxy sealer, epoxy putty based on one-component water-based acrylic resin. It is recommended to use a layer of sealer to strengthen the paint film. Its drying mechanism: about the consumption of about 270 grams per square meter for an 80 micron thick layer of paint, surface drying for 30 minutes and partial drying for 1 hour and repainting for 8 hours will be part of the work routine. You can also use epoxy putty for sealing and leveling the surface.
If the cement surface is fresh, allow the paint to dry well within a month for the longevity and durability of the paint. Cement drying usually takes 29 days to dry all its layers and grains.
After that, try to apply a special primer so that the paint can be applied better on the surface and, as mentioned, the humidity of the cement will not cause the color of the facade of the building to be lost.
If the cement surface is dirty, you can wash it with a water jet, repair the damages with suitable materials, after the surface dries, apply the final color primer.
The use of primer is mandatory for freshly made cement and cement surfaces that have not been painted yet. With this, the durability of the paint is easily guaranteed for the next few years and it will not be damaged in bad weather conditions.
As its name suggests, the exterior of the building is always directly exposed to weather conditions and will suffer the most damage compared to other colors. Therefore, choose the highest quality paint for the facade of the building so that you don’t need to paint the building every year. It is better to use waterproof, insulating, anti-dust and durable paints on the facade of the building in order to benefit from its benefits for many years.
Acrylic colors are among the popular colors that are used all over the country in different climates and have shown positive and surprising results. Also, in the north of the country, where the buildings are exposed to heavy rains, and generally in the western part of the building, this condition dictates that New Seal should be used before applying the paint, and after it dries completely, the facade paint should be applied.
