Although the real stone paint has become the most popular coating material for the exterior wall, many customers and friends still contact the real stone paint for the first time. They don't know much about the construction of the real stone paint. Today, Wan Lei sorted out the construction process of the real stone paint for everyone and the control method of the quality of the real stone paint project for the exterior wall.
Construction process of real stone paint
Leveling → spraying sealing primer → snapping ink lines and dividing grids → sticking double-layer adhesive tape and dividing strips → spraying the first layer of real stone paint → tearing off the first layer of adhesive tape → spraying the second layer of real stone → tearing off the second layer of adhesive tape → mortar joint treatment → spraying two layers of finishing coat
Quality control of real stone paint
1. Small particles of real stone paint shall be used. After spraying, the surface shall be flat, small undulation, uniform and dense particle distribution, and the color shall be the same
2. It is required that the mortar joint shall be horizontal, vertical and uniform in width; special attention shall be paid not to take off the underlying coating when the grid strip is torn
3. For all external corners, the long side shall be opposite to the short side when typesetting, so as to give people the visual effect of whole brick masonry
4. The paper tape should be used as the dividing tape, which has a good adsorption effect on the real stone paint; if the plastic tape is used, it will cause the flowing of the real stone paint. At the same time, during the construction in summer, the tape is required to have good temperature resistance, so as to avoid the melting of the back of the tape with slightly higher temperature, which makes it difficult to tear the tape
5. Grasp the stripping time of the dividing tape. The surface of the real stone paint is dry, and it can be torn off when it is pressed by hand without obvious indentation and stick. Too early tearing and uncovering will lead to the flowing of real stone paint; too late tearing and uncovering will not easily tear off the dividing tape, and will also lead to the uncovering of real stone paint at the mortar joint and the straightness of the mortar joint
6. The real stone paint of the same monomer shall be completed at one time to reduce the color difference.
After some friends finish the real stone paint project, they find that some places of the real stone paint will turn white and white. What is the problem? To find out the reason,
The first is very closely related to the emulsion used in the preparation of genuine stone paint. Some emulsion manufacturers in order to increase the stability of emulsion, the amount of surfactants used, the water resistance of emulsion decreased.
Second, in order to save costs, genuine stone lacquer manufacturers only add a small amount of emulsion, so that after the drying of the stone paint, the film is loose and not dense enough. The water absorption rate of the paint film is large, and the bonding strength is low. Once the rainy weather occurs for a long time, the rain will gradually penetrate into the paint film, resulting in the whitening of the real stone paint film. Third, some stone paint manufacturers add a large number of thickeners such as hydroxymethyl cellulose and hydroxyethyl cellulose in the preparation, and these substances are water-soluble or hydrophilic. The stone paint remains in the coating after film forming, which reduces the water resistance of the coating.
Therefore, in order to avoid the flower of real stone paint, the final thing is to select a real stone paint manufacturer and choose a real stone paint brand with many years of production experience to check the product. For example, wanlei real stone paint started to make real stone paint at the earliest. After more than 10 years of research and development, it has continuously launched new real stone paint products, improved the real stone paint system, so that wanlei real stone paint has better and more stable quality and better construction performance. The new formula of freight non resistance real stone paint is the first in China, bringing a new chapter to the real stone paint industry.
