HF-002 Hongfeng No.2 Water-based Sealant is a colored water-based sealant made from high-performance polymer emulsion and emulsified asphalt as the base materials, supplemented with various additives, suitable for sealing processes in construction engineering.
Suitable for sealing the ends and edges of roofing membranes, and is also suitable for sealing and waterproofing of detailed nodes such as downspouts, pipe roots, eaves gutters, pile heads, parapets, or special-shaped parts with complex structures, easy to crack or deform.
1. Fast drying, with strong penetration ability, suitable for irregular structures and detailed nodes.
2. Outstanding water resistance, maintaining excellent sealing performance even in water-involved environments after application.
3. High product recognition, making it easier to identify whether the construction area has been treated, enhancing the reliability of the waterproofing system.
4. Good compatibility and strong adhesion, can be used in combination with modified asphalt membranes, and has a strong bonding effect with various surfaces such as concrete and wood.

Key Construction Procedures
1. Substrate Preparation:
Thoroughly clean the substrate of dust, sand particles, and impurities to ensure it is smooth, solid, free of oil stains, and without standing water. To ensure adhesion, treat the substrate with a primer if necessary.
2. Application Method:
After opening the can, mix well. It is recommended to apply by troweling and brushing. Depending on the designed thickness, apply in 1-2 coats, ensuring full coverage without any exposed substrate, missed spots, or buildup.
3. Reinforcement of Additional Layers:
For corners, construction joints, downspouts, and pipe roots, reinforce the additional layer with a coating + non-woven fabric method (the non-woven fabric should be around 50-60g/m²). First, apply a layer of sealant to the detailed node areas, and before the sealant surface dries, lay the non-woven fabric to reinforce the additional layer. After pressing it firmly in place, apply another layer of sealant on the surface of the non-woven fabric.
1. During transportation, protect against sun exposure, rain, frost, and avoid compression, collision, ensuring the packaging remains intact and complies with transportation department regulations.
2. Store the product in a well-ventilated, dry area, away from sources of fire and heat. The storage temperature should be between 5-35°C, protect from direct sunlight, and strictly avoid exposure to the sun, which can affect the product's performance. Avoid freezing, as it may impact the product's properties.
3. Under normal transportation and storage conditions, the shelf life is six months from the date of manufacture.
1. Wear rubber gloves and safety goggles or other protective equipment when using the product. If the product accidentally comes into contact with the eyes, rinse immediately with plenty of clean water and seek medical assistance if the condition persists. If the skin is accidentally injured, avoid contact until the wound is fully healed.
2. Use the product opened from the can on the same day, and store any remaining material by sealing the opening and use it as soon as possible.
3. The construction temperature should be between 5°C and 35°C, avoid freezing, and strictly prohibit exposure to the sun. Do not carry out construction in rainy or snowy weather or when rain or snow is forecast within 24 hours.
4. Do not add water or solvents to dilute the product, as it may affect the product's performance.
5. Ensure the waterproof layer is applied evenly, and avoid walking on it before it is dry to prevent damage to the waterproof layer.
6. The complete drying time for each coating is 2 to 12 hours, depending on the environmental temperature and humidity, and the drying time should be appropriately extended in a humid environment.
