Indoor Ultra-Thin Fireproof Paint - Manufacturer Sales of Indoor Ultra-Thin Fireproof Coatings (Mr. Liu: 186^0280^5638) Available in Sichuan, Chengdu, Yunnan, Chongqing, Guizhou, and other regions. Indoor ultra-thin fireproof coatings typically have a coating thickness of less than or equal to 3 mm and belong to the category of intumescent fireproof coatings for steel structures. When exposed to fire, they expand and foam, forming a dense fireproof and heat-insulating layer, thereby delaying the temperature rise of the steel and protecting the steel structure from softening or collapsing during a fire.

Indoor ultra-thin fireproof coatings are suitable for building steel structures that require short-term fire protection, such as light steel structures and space frames.

Construction Reference for Indoor Ultra-Thin Fireproof Coatings:
1. Rust Removal and Cleaning: Before construction, the surface of the steel structure should be derusted, and dust, oil stains, and other impurities should be cleaned to ensure the surface is clean and dry.
2. Applying Anti-Rust Paint: Apply 1-2 coats of anti-rust paint to protect the steel structure from corrosion. The application of anti-rust paint should be done after rust removal and cleaning to ensure strong adhesion of the coating.
3. Construction Method: Construction can be carried out using spraying, brushing, or rolling. When spraying, the thickness should be about 0.10-0.15 mm. After the surface dries, apply the next coat with a thickness of about 0.15-0.20 mm. Subsequent coats should be controlled to around 0.20 mm, not exceeding 0.30 mm.
4. Thickness and Interval Control: The thickness of each application should not exceed 0.3 mm. The interval between applications should be determined by the coating not sticking to the hand (generally around 18-24 hours) until the specified thickness is achieved.
