Characteristics of Vietnam's Weather
Vietnam has a tropical monsoon climate with abundant sunshine, frequent rainfall, and high humidity. In particular, northern Vietnam experiences periods of "nồm" (humid, damp wind) with very high humidity. In central Vietnam, the summer heat is further exacerbated by the dry, hot winds of the Lào, leading to dry conditions and a lack of moisture. This combination can cause paint to blister, peel, and deteriorate, leading to water seepage during rains and a decrease in aesthetic appeal.
Additionally, due to the hot, humid weather and inconsistent rainfall, along with poor waterproofing skills, most houses in Vietnam tend to deteriorate over time. Issues such as mold and algae growth on exterior walls, water seepage through window gaps, and dampness from air conditioning and washing machines can lead to mold, dark stains, yellowing, and unpleasant odors. On humid days, with humidity levels reaching 80-90%, walls can easily become damp. Thus, using low-quality paint can make it difficult to withstand these damaging factors.
According to construction experts, consumers should select high-quality paints based on criteria such as high alkalinity resistance (mold and mildew resistance), high gloss (dust resistance), good adhesion (peeling resistance), and long-lasting color.
How to Choose Paint Suitable for Vietnam's Climate
Choose Moisture and Waterproof Paint Currently, many homeowners choose paint based on color preferences and personal taste. However, when selecting exterior paint, the primary concern should be paint quality. Given Vietnam’s hot and humid climate, it is important to choose paint with high anti-mold and antibacterial properties, as well as excellent waterproofing capabilities to prevent rainwater from seeping into the walls.
Select Paint with Elasticity and Cooling Features In Vietnam, summer temperatures can reach up to 40°C or higher, causing walls to develop small cracks due to the contraction of plaster or slight shifting of the foundation. Rainwater and moisture can easily seep through these cracks, leading to stains and peeling.
Therefore, homeowners should choose paint with good elasticity to protect the paint film from cracking. Products with UV-reflective properties can help reduce wall temperatures, keeping the house cooler during hot summer days.
