Exterior wall real stone paint blooming refers to the phenomenon of white spots or granularities on the surface of real stone paint. This phenomenon will seriously affect the decorative effect of real stone paint, so it needs to be solved in time.
The main reasons for the appearance of real stone paint on the exterior wall are as follows:
Improper treatment of the base layer: Improper treatment of the base layer is the most common cause of the blooming of real stone paint. If the surface of the base layer is uneven, cracked, oily, etc., it will lead to the weak adhesion of the real stone paint, which will fall off or bloom.
Improper ratio of paint: Improper ratio of real stone paint can also lead to blooming. If the consistency of the coating is too high or too low, it will affect the adhesion and hiding power of the coating film, resulting in blooming.
Improper construction: Improper construction is also an important cause of real stone paint. If the coating is applied unevenly and the thickness is inconsistent during construction, it will cause unevenness on the surface of the coating film, resulting in blooming.
Poor climatic conditions: Poor climatic conditions can also cause real stone paint to bloom. If the temperature is too low or too high, and the humidity is too high or too low during construction, it will affect the drying and curing of the coating film, resulting in blooming.
For different reasons for the real stone paint blooming, the following solutions can be taken:
Improper treatment of the base layer: Improper treatment of the base layer leads to the appearance of real stone paint, and the base layer needs to be re-treated. Here's how to deal with it:
Clean up dust, oil and other debris on the surface of the base layer.
Plaster with cement mortar or cement-based polymer to make the surface of the base layer smooth and firm.
Seal the base layer with a primer to improve the adhesion of the paint.
Improper paint ratio: Improper paint ratio leads to the appearance of real stone paint, and the paint needs to be reformulated. The specific preparation method is as follows:
Prepare according to the instructions provided by the paint manufacturer.
Pay attention to the consistency and viscosity of the paint to make it suitable for application.
Improper construction: Improper construction leads to the appearance of real stone paint, which needs to be re-constructed. The specific construction methods are as follows:
Check the consistency and viscosity of the paint to make it suitable for application.
Apply the paint evenly so that the thickness of the coating film is uniform.
Keep the temperature and humidity of the construction environment appropriate.
Poor climatic conditions: Poor climatic conditions cause real stone paint to bloom, and it is necessary to wait until the climatic conditions are suitable before construction. The specific construction methods are as follows:
Construction is carried out when the temperature is suitable (5 35 ).
Construction is carried out when the humidity is suitable (40% 70%).
In addition, before construction, the following things need to be paid attention to:
Choose high-quality real stone paint produced by regular manufacturers.
Construction is carried out in strict accordance with the instructions provided by the paint manufacturer.
Do a good job of preparation before construction to ensure that the construction environment is suitable.
Through the above measures, it can effectively prevent the real stone paint of the exterior wall from blooming.
