Home renovation and hydropower transformation are the first steps in any project, followed by waterproofing. When it comes to waterproofing, there are three main types of materials available on the market, each with its own unique features. In the context of household waterproofing, which material is most suitable? Let's take a closer look at the options.
The three commonly used waterproofing materials include new polymer cement-based coatings (such as universal waterproof paste and flexible waterproof paste), 911 polyurethane, and waterproof membranes. Each has its own advantages and disadvantages, especially when it comes to application in residential settings.
Waterproof membranes are not easy to join together and are primarily used for large-scale roofing projects. They are not ideal for small areas like bathrooms or kitchens. On the other hand, 911 polyurethane coatings are often avoided in home use due to their volatile toxic gases, difficulty in adhering to ceramic tiles, and the need for dry surfaces during application. The new polymer cement-based waterproof coating, however, is a more practical choice for households.
This type of coating combines organic polymer liquid with inorganic powder materials, offering the flexibility of organic compounds and the durability of inorganic ones. Once applied, it forms a strong, elastic, and long-lasting waterproof layer. It is environmentally friendly, easy to apply, and resistant to aging and cracking, making it an excellent option for home use.
**First, comparing material properties and composition**
New polymer cement-based waterproofing is water-based, made from a combination of organic polymers and inorganic powders. This blend ensures both high elasticity and good durability. These products are factory-prepared according to strict formulas, ensuring consistent quality and performance.
In contrast, 911 polyurethane is typically oil-based. It is a single-component product that includes isocyanate groups, catalysts, fillers, and solvents. However, since it’s often produced by smaller manufacturers, the quality can be inconsistent, and some may even pose health risks due to harmful emissions.
Waterproof membranes are usually made from petroleum-based materials and reinforced with fabrics like polyester or glass fiber. Their production involves multiple complex steps, making quality control difficult. As a result, they are less reliable and harder to work with in residential settings.
**Second, construction convenience and efficiency**
One of the biggest advantages of the new polymer cement-based coating is its ease of application. It can be mixed and applied directly, forming a solid waterproof layer quickly and efficiently. This makes it a preferred choice for DIY projects and professional contractors alike.
**Third, resistance to aging and environmental conditions**
The new polymer cement-based coating offers excellent resistance to aging, cracking, and moisture. It remains effective even in humid environments like bathrooms and kitchens. Unlike oil-based polyurethanes, which degrade under UV exposure and are only suitable for hidden areas, this coating is durable and long-lasting.
Waterproof membranes, on the other hand, are prone to aging, cracking, and peeling over time, especially when exposed to natural elements. This makes them unsuitable for long-term use in residential areas.
**Fourth, cost comparison**
Cement-based waterproofing materials are cost-effective, requiring less material per square meter and lower labor costs. A 1.5–2.0mm thick layer is sufficient for most applications. In contrast, oil-based polyurethane requires a much thicker layer, consuming up to 2.5–3.0kg per square meter, which increases both material and labor costs.
Waterproof membranes are also expensive due to the complexity of installation and the high labor involved in splicing and sealing.
**Fifth, safety during construction**
Cement-based coatings are safe to use in any environment, without the risk of toxic fumes or explosions. In contrast, polyurethane coatings require sealed, well-ventilated spaces, which can be dangerous for workers and may lead to health issues or accidents.
Overall, the new polymer cement-based waterproof coating stands out as the best option for household use, combining performance, safety, cost-effectiveness, and ease of application. It is the ideal solution for protecting your home from water damage.
