Colorful stone like material is a hot exterior wall decoration material in the market. Once sold, it is welcomed by the majority of users. But now there are many colorful stone like coatings in the construction process and after construction if not handled properly, which causes this phenomenon?
1. The construction temperature is too low and the humidity is too high
The drying of water in water stone like material needs to be in the best environment to ensure the uniform and full color particles and achieve realistic effect. If the construction environment temperature is too low or the humidity is too high, the coating can not be fully dried and cause whitening and blooming
2. Base efflorescence
The water content of base course is too high, which leads to the alkali resistant sealing primer unable to neutralize the base alkali, which makes the base alkali damage the coating film of water in water stone like coating and causes whitening and blooming
3. Poor flatness of base course
The smoothness of the base course is too poor. After the construction of the stone like material, the sun shines on the uneven wall surface, causing the effect of blooming visually
4. Short recoating time
If the paint film is not dry enough, it will start to brush the surface, which results in the water in water stone like material paint film drying process of water vapor can not be discharged outside the surface, causing the water in water stone like paint finish to bloom
5. Improper construction
The construction is not standard, not in accordance with the construction technology and material description
6. Product quality problems
The problem of the material itself, the mismatch of the emulsions and auxiliaries of the colorful stone like materials, or the poor synergy of raw materials among the raw materials enterprises, led to the white flower blends of the stone like paints.
