Application Instructions

Ideal for high-end residential buildings, villas, hotels, apartments, schools, and factories.

Base Layer Leveling:
o Use high-quality exterior putty with fine particle size, high hardness, and waterproof/alkali-resistant properties.
o Strictly follow water-to-putty ratios, ensuring no clumps or lumps during mixing. Apply 1-2 coats.
Primer Application:
o Stir the primer thoroughly before use. Follow the specified dilution ratio, avoiding excessive dilution.
o Apply 1 coat evenly using a roller or sprayer. Use a brush for corners and gaps to ensure full coverage.
Topcoat Application:
o Stir the paint thoroughly before use. Follow dilution guidelines if required.
o Use a roller or spray gun to apply 2 coats evenly. Maintain a drying interval of 4 hours between coats.

Precautions

1. Surface Inspection:
o Before application, strictly inspect and accept the base surface in accordance with national standards.
o Ensure the surface is flat, clean, solid, and free of oil, mold, algae, dust, or other contaminants.
o The pH value must be <10, and moisture content must be <10%.
o Do not proceed with application when the wall temperature is below 5°C, relative humidity exceeds 80%, or during strong winds, rain, snow, or thunderstorms.

2. Worker Safety:
o Workers must adhere to local safety regulations and wear appropriate protective gear, including safety goggles, gloves, and professional work attire.
o Ensure suspended platforms, scaffolding, or other construction tools are sturdy and reliable.

3. Construction Planning:
o Plan the work area and workforce to ensure each working surface is completed in one go.
o Position seams at logical points, such as floor divisions or at internal/external corners, to avoid visible joints.
o Use materials of the same batch and color code on the same project to avoid color inconsistencies.

4. Separation Joint Setup:
o Set up joints scientifically to prevent cracking and ensure decorative effects.
o Tape Joint Method: After the primer dries, mark the joints, divide sections, and apply masking tape. Remove the tape before the topcoat dries.
o For small sections (<0.5 m²), applying black primer is recommended to improve work efficiency.

5. Material and Application Techniques:
o Follow specified water dilution ratios and construction techniques.
o Operate in strict accordance with guidelines.

6. Tool Cleaning and Waste Disposal:
o During work interruptions or upon completion, promptly clean tools with clean water.
o Do not discard leftover paint or waste into drains or water sources.
o Handle waste materials, including containers and unused paint, in accordance with local environmental regulations.

7. Eye Contact:
o If the product comes into contact with the eyes, rinse immediately with clean water and seek medical attention if discomfort persists.

8. Authenticity Assurance:
o Avoid purchasing products with incomplete labeling to protect user rights. Be cautious of counterfeit products.

9. Further Information:
o For additional information, consult your local distributor or request the product manual.
