Cement-Based Thick Fireproof Coating

Recommended Applications
Indoor steel structures in factories and plants in the petrochemical, chemical, power, and general industries, and indoor steel structures in airport terminals, hotel lobbies, cinemas, gymnasiums, and high-rise buildings.

Instructions
1. Application should be performed after the steel structure has undergone rust removal and anti-rust treatment and has passed acceptance. Before application, clean the surface of the substrate of dust and oil. 2. This product is a two-component product and requires careful mixing before use: the first Paint should be water: primer: powder = 70:40:40; for subsequent applications, the ratio should be water: primer: powder = 70:40:80; for spray applications, the ratio should be water: primer: powder = 100:40:80. The water ratio can be adjusted based on actual conditions. First, add the primer to the water in the correct proportions and stir thoroughly. Then add the powder and stir again. The mixed slurry should be used within 90 minutes.
3. Application Method: The first Paint should be sprayed to a thickness of approximately 5mm, forming a continuous, uniform sealant layer. Subsequent Paints can be applied by spraying or mopping. The thickness of each Paint should not exceed 10mm for spraying and 12mm for mopping, until the specified thickness is reached. Allow at least 24 hours between Paints before applying the next Paint. The required Coating thickness for different fire resistance ratings is specified in the product data sheet. 4. Surface Decoration: If spray application is used, the Coating will have a uniform granular appearance and generally will not require smoothing. If smoothing is necessary, it should be performed after the final spray Paint. If surface decoration is required, other decorative Coatings may be sprayed or brushed on the fire-retardant Coating. (For higher decorative requirements, it is advisable to first apply putty to the fire-retardant Coating for leveling.)
5. For special climatic conditions or special use environments, an appropriate amount of 707 glue should be added as a primer during the first Paint. The ratio should be 70:8:40:40:water:707 glue: intermediate agent: powder. First, add the 707 glue to the water and stir thoroughly. Then, add the intermediate agent and powder in sequence.
6. When the Coating thickness exceeds 25mm, the diameter of the steel pipe column exceeds 1000mm, or the width of a section of the component exceeds 600mm, mesh reinforcement is recommended.
7. This Coating is suitable for indoor use. The Coating should be protected from sunlight and rain during and after application.

Application Precautions
Avoid application when the ambient temperature is below 0°C. The steel plate temperature must be at least 3°C ​​above the dew point.
Do not apply in rainy or snowy conditions, or if rain or snow is expected during the Coating or drying process.
The first Paint must be primed, and the thickness of the primer sprayed should be controlled within 5-8mm.
The paint film thickness should be appropriate, 8-10mm per Paint. Failure to do so will result in poor drying and paint film defects.
