5. Product Features
1. Bright white color: High whiteness, allowing for a variety of light-colored decorative effects.
2. Fine texture: Uniform particle size, smooth application, and high surface flatness.
3. Strong adhesion: It bonds tightly with the substrate and is unlikely to delaminate or become hollow.
4. Excellent durability: Outstanding frost resistance and impermeability, with a long service life.6. Application scenarios
Widely used in residential, commercial, municipal engineering, and other fields, covering applications such as exterior wall true stone paint substrates, interior wall latex paint primers, and artistic coating designs.
7. Success Stories
8. Construction Method
1. Substrate preparation: Remove oil stains and dust from the surface, then moisten with water.
2. Mixing the ingredients: Add water according to the specified ratio (a recommended water-to-cement ratio of 0.4–0.5) and mix until the mixture is uniform and free of lumps.
3. Application during construction: Apply evenly using a trowel, controlling the thickness according to requirements (typically 1–3 mm).
4. Curing: After construction, maintain moist curing for 7 days, and avoid exposure to direct sunlight or freezing.9. Precautions for Use
Construction environment temperature: -5°C to 35°C. The water-to-cement ratio is an important performance indicator for this product. Please add water according to the manufacturer’s specified water-to-cement ratio, and use mechanical mixing equipment to ensure thorough and uniform blending before construction! If the water-to-cement ratio is improperly adjusted, it may affect the product’s performance. This product is a finished item—do not add any other substances arbitrarily, as this could compromise its functionality and quality system! If this product has expired, it should be properly reconditioned before reuse. Any leftover material that is not fully used after mixing must never be mixed with fresh material for further use! When carrying out outdoor construction in rainy weather, a rain shelter must be set up. The mixed material must be used within 30 minutes; once the initial setting time has passed, the slurry will begin to set and lose its effectiveness! Once the package is opened, the contents must be used up in one go to prevent moisture absorption and caking.
