Key Application Techniques and Precautions for Eco-friendly Rigid Urethane Paint

Section 1: Environmentally friendly rubber paint should meet the following standards:

1. The total Volatile Organic Compounds (VOC) content of the paint: Organic volatiles pose direct harm to the environment and to us humans.

2. The toxicity of solvents: those that, upon contact or inhalation, can cause diseases in the human body. Toxic solvents pose direct hazards to construction workers.

3. D3 is about user safety: Generally, after paint dries, its solvents are mostly volatile, but this takes time, especially for room temperature curing paints. Some solvents evaporate slowly. Although the amount of these solvents is small, prolonged contact with them can cause health issues if they are toxic. Therefore, it is crucial to limit the use of toxic solvents during preparation.

Section II: Application Techniques for Eco-friendly Ru Paint

Scrape away old paint → Apply joint compound, spot sanding → Apply first full coat of joint compound, sanding → Apply second full coat of joint compound, sanding → Apply sealing primer → Apply first coat of paint → Patch and sand joint compound → Apply second coat of paint → Sand to a smooth finish, ready for delivery.

Construction Key Points:

Substrate treatment is a crucial step in ensuring construction quality, with the complete drying of the walls being the most fundamental requirement, typically requiring a period of 10 days or more. The wall surface must be smooth, with at least two thorough coats of putty to meet standard requirements. The application methods for rubber paint can include brushing by hand, rolling, and spraying. The painting process should be continuous and rapid, completed in one go. The application of rubber paint should be even, without any missed spots or drips. One coat should be followed by one sanding, with generally two or more coats applied.

Cautionary Notes:

1. The joint compound should be compatible with the paint's properties, ensuring it is sturdy and durable, with no chalking, peeling, or cracking. Waterproof joint compound should be used in damp areas such as bathrooms.

2. Ensure the liquid is thoroughly mixed. If the viscosity is too high, you may add a small amount of it. If the viscosity is low, you can add a thickener.
