As more people become aware of the importance of home decoration, the demand for coatings has evolved beyond basic aesthetics. Waterproof and heat-insulating coatings have emerged as a modern solution to address both thermal comfort and moisture protection. But what exactly are they? If you're not familiar with this innovation, let's take a closer look and explore its benefits and applications.
What is Waterproof and Heat-Insulating Coating?
Waterproof and heat-insulating coatings are advanced materials designed to reflect and radiate heat, offering a unique combination of insulation and weather resistance. These coatings integrate reflection, radiation, and hollow microsphere technology to create an effective cooling system. By reflecting sunlight and reducing heat absorption, they help maintain a cooler indoor environment without relying heavily on air conditioning.
Key Features of Waterproof and Heat-Insulating Coatings
One of the most notable features is its strong thermal insulation capability. When applied to roofs and walls, it can reflect up to 90% of solar radiation, significantly reducing heat buildup inside the building. This makes it ideal for keeping homes cool in summer and comfortable throughout the year, even without air conditioning.
These coatings also exhibit excellent weather resistance, maintaining their structural integrity between -35°C and 150°C. Their strong adhesion ensures compatibility with various surfaces, including concrete, metal, and glass.
Another advantage is their waterproof and self-cleaning properties. A 3–6mm thick layer provides reliable moisture protection, while the lotus leaf effect allows water to roll off easily, making maintenance simple and efficient.
The application process is straightforward—just one or two coats are needed, making it more efficient than traditional insulation methods. It can be applied using spray, brush, or roller, saving time and labor costs.
In terms of energy efficiency, these coatings can reduce heating costs by 25–35% in winter and cooling costs by 30–56% in summer. At just 7.5px thick, it offers performance comparable to 30mm of polystyrene insulation.
Environmentally friendly and safe, these coatings are water-based and non-toxic, making them suitable for residential and commercial use. They also offer high cost-effectiveness, combining durability, performance, and affordability.
Construction Techniques for Waterproof and Heat-Insulating Coating
The first step involves preparing a solid, clean base surface free of dust, oil, and moisture. A primer should be applied to ensure proper adhesion and allowed to dry before proceeding.
Next, joints and corners should be pre-coated and reinforced with tire base materials to enhance durability. The waterproof layer should be applied in thin, multiple coats, ensuring each layer is fully dry before applying the next. Brushing or spraying can be used depending on the project scale.
If tire base reinforcement is required, it should be placed evenly on the wet coating and fully covered with paint to form a seamless waterproof layer. The thickness of the coating should not be less than 1.0mm to ensure effectiveness.
After the waterproof layer is completely dry, a protective layer can be added. Finally, decorative coatings can be applied once the base is fully cured.
In summary, waterproof and heat-insulating coatings are a smart choice for modern construction, offering long-term benefits in energy savings, comfort, and durability. Whether you're renovating your home or working on a commercial project, these coatings are worth considering.
