Paint is a fundamental material in home decoration, but today it's also becoming a creative tool. More and more people are using paint not just for walls, but to express their personal style by drawing unique patterns on surfaces. However, the correct use of paint is essential—not only for aesthetics but also for maintaining a healthy indoor environment.
One common issue when painting walls is the problem of uneven absorption. Sometimes, the wall surface absorbs the paint too quickly, which prevents the latex paint components from settling properly. This can lead to color changes, peeling, cracking, or even mold growth, making the whole process frustrating.
To avoid these issues, applying a primer before the topcoat is crucial. A water-based sealing primer helps prevent the wall from becoming alkaline due to moisture, especially in humid conditions. It acts as a barrier against alkali penetration, stops the formation of water-soluble salts, and prevents the wall from turning white or efflorescing. Additionally, the primer smooths the surface, improves adhesion, and reduces the amount of topcoat needed. This not only saves money but also enhances the long-term durability and appearance of the paint. It’s important to use the same brand or compatible products for both primer and topcoat to avoid chemical reactions that could damage the finish.
Choosing high-quality paint can significantly enhance the overall look and value of your home. Opt for well-known brands available at reputable stores like Haomeijia Building Materials Supermarket or Meijia Decoration Plaza.
Another common challenge is wall cracks or peeling after painting. Even with good paint, problems may arise if the putty used during construction isn’t sufficient or of poor quality. Some companies cut corners by using low-grade materials or not following proper procedures, leading to unsatisfactory results.
There are three main types of interior wall paints:
1. **Low-grade water-soluble paints** – Made by dissolving polyvinyl alcohol in water and adding pigments. These are not resistant to water or alkali and tend to peel off when damp. They are typically used in temporary or low-cost spaces.
2. **Latex paints** – Water-based and highly durable, these offer better resistance to water and weathering. They come in various finishes, such as flat or glossy, and are considered medium to high-end. Though more expensive, they provide excellent performance and are widely used.
3. **Colorful paints** – Popular for their decorative appeal, these paints use nitrocellulose as a film-forming agent and can create multiple color effects with a single spray.
While exterior latex paints focus on UV resistance for long-lasting color, interior wall paints prioritize scrub resistance and durability. Understanding the differences between them ensures you choose the right product for your space.
