In regions with frequent rainfall and typhoons, buildings face severe waterproofing challenges. RF52 – Elastcoat and RBC703 are two waterproofing materials designed to meet such demands, offering excellent weather resistance and ease of application. Whether used by professional teams or general users, both products are suitable for construction without requiring specialized tools, making waterproofing projects more accessible. They are applicable to various structures such as rooftops, exterior walls, basements, and bridges.
Material Characteristics and Application Scenarios
- RF52 – Elastcoat uses a high-elasticity polymer formula with excellent flexibility and adhesion. It can stretch and contract with minor substrate movements, reducing the risk of cracks and water leakage. It is ideal for rooftops and wall surfaces, especially effective during thunderstorm seasons.
- When used with non-woven fabric, it forms a reinforced layer that enhances tear resistance and durability.
- It offers UV and acid rain resistance, making it suitable for long-term outdoor exposure.
- RBC703 is a high-performance polymer-based primer known for its fast curing and abrasion resistance. When used with cement mortar, it forms a robust protective layer suitable for high-wear structures such as basements and bridges.
- It has strong adhesion and crack resistance, capable of filling small cracks and pores to improve sealing performance.
Application and Performance
Both products have undergone quality and environmental testing and maintain stable performance after curing under humid, high-temperature, or low-temperature conditions. During application, the materials are easy to mix and brush on, requiring no special tools and suitable for users of all experience levels.
- RF52 – Elastcoat
- Available in various colors (white, black, green, gray)
- Solid content around 70%, usage approximately 1.3 kg/m²
- Can be diluted with 20–30% clean water, but not recommended to exceed 30%
- RBC703
- Transparent liquid with strong penetration
- Used in combination with cement mortar
- Usage approximately 0.2 kg/m²
Storage and Cleaning
Unopened products can be stored for up to 12 months in a dry, ventilated indoor environment at 5–30°C. Tools used during application can be cleaned with water before the coating dries, making operation simple and helping maintain a clean work environment.
Technical Comparison and Selection Advice
From a technical perspective, RF52 – Elastcoat emphasizes elasticity and structural reinforcement, making it suitable for surface waterproofing. RBC703 focuses on rapid film formation and abrasion resistance, ideal for deep penetration and high-wear environments. Depending on the construction scenario and specific needs, users may choose either product individually or use them together to achieve more comprehensive waterproofing results.
