Exterior wall real stone paint is a kind of imitation stone paint with realistic decorative effect, which has the advantages of strong weather resistance, dirt resistance, easy cleaning, rich color, etc., and is widely used in building exterior wall decoration. The construction of exterior wall real stone paint is a highly technical work, and the following small details need to be paid attention to to ensure the construction effect.
1.Grassroots treatment
Substrate treatment is an important part of the construction of exterior wall stone paint, and poor treatment of the base layer will affect the adhesion and service life of the real stone paint. The base treatment should meet the following requirements:
The surface of the wall should be smooth, dry, free of oil, floating ash and other debris.
If there are cracks, bulging and other defects on the surface of the wall, they should be repaired.
The walls should be waterproofed to prevent rainwater from seeping.
2.Paint ratio
Real stone paint is a kind of multi-component coating, which should be proportioned according to the construction instructions before construction, and inaccurate proportioning will affect the construction effect of the coating.
3.Construction method
There are generally three types of real stone paint construction methods: spraying, rolling coating and brushing. Spraying is the most commonly used method for the construction of real stone paint, which has the advantages of high efficiency and good effect. The roller coating and brushing construction process is simple, but the construction efficiency is low.
4.Construction details
The following details should be paid attention to during the construction process:
When spraying, it should be sprayed evenly to avoid missing coating, flowing and other phenomena.
Attention should be paid to the thickness of the paint when rolling and brushing, as too thick the paint will cause the surface of the real stone paint to be uneven.
After the construction is completed, the construction tools and the site should be cleaned up in time.
Precautions for construction in rainy days
The air humidity is high on rainy days, which is not conducive to the construction of real stone paint. The following matters should be paid attention to during construction on rainy days:
Avoid construction in rainy days, and postpone construction in case of rain.
During construction on cloudy days, attention should be paid to controlling air humidity to avoid excessive air humidity.
After the construction is completed, it should be maintained in time to prevent rainwater from seeping.
All in all, exterior wall real stone paint construction is a meticulous job, and there are many details that need to be paid attention to. During construction, it should be operated in accordance with the construction specifications to ensure the construction effect.
