Condition 1: Block
Because the wall surface is not completely dry or foreign water penetrates, a white crystalline solid is formed on the paint surface.
Solution: Before painting, ensure that the wall surface treatment (especially the new wall) has been more than two weeks; if it is under construction, stop it immediately and wait about two weeks after the wall surface is dry and continue; if the paint surface has been brushed and presented In case of splitting, the paint shall be completely scraped off to ensure that the wall is dry and repainted.
Condition II: Blistering
Before the paint surface is completely dry, the water penetrates into the paint, causing the paint film to lose its adhesiveness and to foam on the surface.
Solution: Avoid painting in rainy season or high humidity season; use primers of the same brand and the same product series; local blistering can be scraped individually, and smooth the edges of the scraped part after grinding. Paint, then re-brushing; such as a large area to be completely scraped off, and when there is no water on the wall when the construction.
Condition 3: Mold
It usually appears on old walls or on walls that have been painted with an anti-microbial formula. It is gray and grows under sufficient moisture and moisture.

Condition 4: Watermark
Due to moisture, it is patchy and its color is usually darker than the original color.
Solution: Make sure that the wall surface is dry before painting; if it is on the surface of old paint, check whether there is external leakage or pipe cracking; large-scale watermarking will affect the appearance, and the watermark source should be eradicated and removed until the wall is dry. Repaint.
Condition 5: Flaking
The reason that the paint peels off is the condensation of water under the paint layer, the expansion or contraction of the surface of the paint, the moisture, dirt, grease or powder on the surface of the old paint.
Solution: Before painting, the walls must be thoroughly cleaned and dried to ensure that they are smooth and free of pores. All old paint powder is removed.
Condition 6: Discoloration
Walls are exposed to intense sun exposure or are contaminated with chemicals (such as alkalis).
Solution: The use of high quality, especially the use of special formula wall paint, can make the wall color lasting, both mildew, anti-discoloration, and can be washed with water to keep the wall clean.
