1. Color
The color requirements of exterior wall paint should comply with relevant national standards, have good color stability, and be resistant to fading, discoloration or color difference. Appropriate colors should be selected according to different use places and environments to achieve decorative effects.
2. Adhesion
The adhesion of exterior wall paint refers to the strength of the paint’s adhesion to the wall. It should be able to maintain the adhesion of the coating film in harsh environments without peeling or cracking. Paint with strong adhesion has good durability and decorative effect.
3. Weather resistance
Exterior wall paint must be able to withstand long-term ultraviolet radiation, wind and rain and other harsh climatic environments, without color difference, fading, yellowing and other phenomena. Weather-resistant coatings are important for wall protection and aesthetics.
4. Water resistance
Exterior wall paint must have good water resistance and will not cause blistering, cracking or peeling of the paint film due to moisture intrusion. It can maintain the stability and adhesion of the coating film in humid environment.
5. Heat resistance
Exterior wall coatings must be able to withstand high-temperature environments without losing their adhesion due to high-temperature baking or high-temperature oxidation reactions. Coatings with strong heat resistance are more suitable for summer construction.
6. Cold resistance
Exterior paint must also be cold-resistant and not crack or peel due to freeze-thaw changes in extremely cold environments or low temperatures. Paints with strong cold resistance are more suitable for winter use.
7. Others
Exterior wall paint must also be mildew-proof, algae-proof, anti-fouling, and easy to clean to ensure the quality stability and decorative effect of the coating film.
In summary, there are many factors to consider when choosing and using exterior paint. You shouldn’t just focus on price or a manufacturer’s reputation, but choose the product that’s right for you on a case-by-case basis. During the construction process, the instructions and standards for the use of paint should also be followed to ensure the decorative effect and protective performance of the wall.
