I.Real Stone FinishWhich is better, water-based or sand-based?
Water-based sand and real stone paint are familiar to many. It is a common coating for building facades. Real stone paint is a coating with a decorative effect similar to marble and granite, with excellent simulation effects. Water-based sand is a combination of water-based coatings and real stone paint, used to simulateLychee noodles granite stone.
1、There are distinct characteristics between water-based sand and real stone paints. First, let's discuss real stone paint. Real stone paint offers a high degree of realism and provides fire protection, waterproofing, moisture resistance, and high-temperature resistance. In contrast, water-based sand paints use emulsion to completely encapsulate the sand particles, allowing for the formation of a film. When applied to walls, they effectively prevent dirt and dust from adhering. Therefore, their characteristics are completely different.
2、The applications of water-based and real stone paints are also different. Real stone paint is more suitable for interior decoration of various buildings, especially for decorative purposes in areas with distinct surfaces. Water-based stone paint is a imitation ofLychee noodles granite, and is generally not suitable for interior decoration, but is more suitable for outdoor use.
3. Disadvantages of natural stone paint: Natural stone paint also has several disadvantages during construction. For example, due to sudden changes in temperature, the drying rates of the inner and outer layers can differ, leading to cracks inside. If these cracks are not addressed promptly, they can cause cracks to appear on the surface.
4、What are the disadvantages of water-based sand-based materials: Water-based sand-based materials have limited applications and are typically used in construction projects. Their aesthetic appearance may not be ideal for interior construction.
Two, the differences between water-based sand and pebble paint.
1、Difference in realism
From a simulation perspective, real stone paint is a coarse imitation product with a simulation rate of approximately 50%, capable of replicating color and texture but not patterns. In contrast, sand-based paint has a simulation rate of approximately 95%, with more realistic and detailed patterns.
2、Differences in crack resistance
The latex content in genuine stone paint is around 15%, resulting in a rigid film after drying, which consequently has poor crack resistance. Latex content of sand-based emulsion is above 40%, and after the film has completely dried, the latex can form a complete film, resulting in better crack resistance.
3、Distinction between breathability and water permeability
Real stone paint has good breathability, but due to the low latex content, the spaces between the pigments cannot form a film, which can lead to water leakage over time. Water-based sand paints have limited sand content and smaller pigment particle sizes, which can effectively prevent water leakage after forming a film.
4、Difference in stain resistance
The pronounced texture of True Stone Paint prevents proper film formation, and over time, dust can easily penetrate the coating, making it difficult to clean. Although textured coatings like "water-based sand" also have a textured surface, dust only sits on the surface and does not penetrate. Rainwater can easily wash away the dust.
5、Differences in weather resistance
Real stone paint utilizes pure acrylic emulsion with a content of approximately 15%, which exhibits poor aging and water resistance after film formation. Sand-based paints using silicone-acrylic emulsions have a content of 40% or more, offering superior water and UV resistance compared to real stone paint. Their service life can reach 20 years or more.
