Vietnam is located in a tropical climate zone with two distinct seasons: sunny and rainy, and the exterior walls are directly exposed to prolonged rains and harsh sunlight. These are also the factors that cause the exterior paint of the building to quickly deteriorate and fade, affecting the aesthetics as well as reducing the life of the building.
Therefore, to protect the exterior paint layer from the effects of time and harsh natural conditions, people should pay attention to some factors when choosing exterior paint.
House paint includes interior paint and exterior paint. In which, interior paint is the paint inside the house, with outstanding advantages such as smoothness, gloss and color fastness, creating aesthetic beauty for the whole house.
It is necessary to ensure proper waterproofing procedures and good surface preparation before applying exterior paint.
As for exterior paint, in addition to aesthetic factors, the ability to resist environmental impacts such as waterproofing, dustproofing, moldproofing, insulation, heat resistance or UV resistance is also emphasized.
Color fastness
Color fastness directly affects the aesthetics of the house. Because after a long time, exposed to many weather effects, the paint color can fade, discolor and no longer be the same as the original.
Exterior paints with long lasting colors will also save homeowners money. Because the more durable the paint is, the longer and less frequent the maintenance will be.
Therefore, when choosing exterior paint, in addition to choosing a harmonious paint color, the paint layer needs to ensure color fastness, prevent moss, mold, and keep the paint film clean and beautiful.
In addition, it is necessary to ensure proper waterproofing procedures, good surface preparation, use of exterior paint, and compliance with the correct drying time between coats to prolong the protection and avoid damage.
Waterproofing
An equally important factor to consider when choosing exterior paint is moisture and water resistance.
By choosing quality paint, the house's paint layer will be protected, not broken in structure, and peeling will be limited when exposed to long-term rainwater or humidity from the environment.
In addition, you should choose paint that is resistant to dirt, helping the surface to clean itself from dirt, keeping the house beautiful.
Has stretch and cooling properties
There are many reasons that cause wall surfaces to crack, such as improperly built walls, subsidence, external forces, etc. Therefore, when choosing exterior paint, you should choose paint lines with elastic paint films that can cover small cracks, helping to protect the wall and waterproof better.
Alkali resistance
In addition to fading and paint discoloration, experts also point out that using poor quality exterior paint will soon lead to other unfortunate damages such as alkalization and color bleeding with white or yellow streaks spreading in patches on the wall.
This condition often occurs when using paint that does not have alkali resistance or has low alkali resistance. In humid weather, the paint film immediately peels off the surface, losing its protective layer, creating conditions for external factors such as rain and sun to attack, causing the house to deteriorate.
Therefore, using quality exterior paint will help limit this phenomenon, ensuring the aesthetics of the project.
Anti-mold
In addition to alkalization, mold can also appear on the exterior walls of buildings due to the use of paint that does not contain mold killers or has poor effectiveness. Over time, this will corrode the walls and reduce the life of the building.
Therefore, users should choose paint lines with high anti-mold and antibacterial properties, helping the surface to always be shiny, protecting the paint film to be durable and beautiful for longer.
UV protection
UV rays can affect the structure of the wall. Therefore, choosing a paint with UV resistance will help protect the paint film from the weather better.
In addition, when choosing exterior paint, you need to pay attention to the environmental friendliness factor. Safe exterior paint is the type that does not contain compounds harmful to human health such as lead, mercury, low content of volatile organic compounds...
