YN-C905 Likai Acrylate Elastomeric Waterproof Coating

1. High strength, high elongation, low temperature resistance, aging resistance, and suitable for exposed use;
2. Strong adhesion and good elongation;
3. Can be directly applied on various wet or dry substrates;
4. Single-component, simple construction, and short construction period;

1. Base Surface Preparation: The base surface should be flat, clean, firm, free from leakage and standing water. Uneven areas, protrusions, and cracks should be leveled, and internal and external corners should be rounded.
2. Construction: Apply the coating using a rubber squeegee or roller brush, usually in 2-3 coats. The application should be even and consistent, with no missed areas. Subsequent coats should be applied after the previous coat has dried to the touch.
3. Ensure even application without local sedimentation. Prevent sagging on vertical and inclined surfaces.
4. Before the coating film has cured, protect it from being stepped on, piled with heavy objects, or punctured by sharp objects.

1. The construction temperature should be between 5°C and 35°C. Do not construct during rainy weather or when there is standing water on the base layer.
2. The coating film takes 2-3 days to fully dry. In humid environments, the drying time should be appropriately extended.
3. A closed water test can only be conducted after the coating film has fully dried. After passing the inspection, non-exposed materials should have a protective isolation layer constructed according to design requirements.
4. Do not add water to the coating during application. Keep the bucket lid closed to avoid direct sunlight.

1. Brush painting, roller painting, and scraping methods can be used.
2. When applying with a roller or brush, 2-4 coats can be applied according to the required coating thickness, with a time interval of 3-6 hours between each coat.
3. For large-area waterproofing, it is recommended to apply the coating to vertical surfaces first, followed by horizontal surfaces. Apply in 2-3 coats, with each subsequent coat applied only after the previous coat has completely dried. Apply the subsequent coats in a direction perpendicular to the previous one.
4. If there are cracks of 3mm or more on the roof, the gaps should first be filled with a mixture of this product and talcum powder or other powders to form a thick paste. Then, apply this product as per the usual construction process.
