The characteristics of real stone paint, explained by a natural real stone paint manufacturer in Zhengzhou for exterior walls.
Zhengzhou exterior wall natural stone paint productionThe manufacturer believes that natural stone paint, with its rich and full colors and approachable texture, attaches the original charm and beauty of stone to the wall through spraying, protection, and decoration, giving the wall a natural stone effect visually.
Zhengzhou exterior wall natural stone paint productionThe manufacturer believes that the base materials for building exterior walls are mostly cement mortar or concrete surfaces, characterized by many voids and strong alkalinity. The porous structure makes it highly absorbent, resulting in a surface that is not smooth enough, which can easily cause the paint film to wrinkle and may lead to rapid drying of the paint film, causing cracking and waste of the topcoat. Strong alkalinity can lead to chemical degradation of the resin in the coating, accelerating aging, reducing the lifespan of the coating, and even causing whitening and efflorescence. The excellent sealing and isolation function of the alkaline-resistant primer separates salts and alkalis from the natural stone paint and penetrates deeply into the substrate, generating strong mechanical bonding force, enhancing the adhesion of the coating, and overall improving and ensuring the lifespan of the natural stone paint system.
Zhengzhou exterior wall natural stone paint productionThe manufacturer believes that primers can be divided into transparent and black primers. So, how to choose between transparent and black primers? What are the differences between these two differently colored primers? The main difference lies in the division of the wall. If the wall is divided into large sections or not divided, transparent primer should be used. If the wall is divided into large sections or not divided, black paint should be used for outlining; if the wall is divided into small sections, black primer should be used. Aside from this distinction, there is actually not much difference between transparent and black primers, so there is no need to be overly concerned when choosing.
The Zhengzhou exterior wall natural stone paint manufacturer believes that the topcoat is mainly used to enhance the waterproof, stain-resistant, and UV radiation resistance of the natural stone paint coating, and it also facilitates future cleaning. Without a gloss varnish, it is easy for the natural stone paint coating to suffer from water resistance issues, whitening, and pollution, shortening the lifespan of the natural stone paint.
The Zhengzhou exterior wall natural stone paint manufacturer believes that the unevenness, hollowing, and peeling of natural stone paint are related to the treatment of the underlying layer. The unevenness of the natural stone paint is caused by uneven treatment of the underlying layer. The hollowing issue is due to the underlying layer being raised, making it feel like the natural stone paint is protruding. Therefore, the underlying layer must be well treated before spraying natural stone paint.
The Zhengzhou exterior wall natural stone paint manufacturer believes that before spraying natural stone paint, it is essential to apply a special primer for natural stone paint that is alkaline-resistant and moisture-proof. The uneven and hollow areas should be scraped until they cannot be removed, then floating dust should be cleared, and a sealing primer should be applied again. After the primer is completely dry, waterproof putty should be used to level it, and then natural stone paint should be sprayed. The hollowing phenomenon is generally related to the substrate; if the quality of the putty powder is too poor and it has not been properly treated before construction, hollowing will occur.
