Base treatment and construction methods
1.Substrate treatment
1.1 Surface treatment of steel structures is the basic condition to ensure the durability of fire retardant coatings. According to different base materials, the surface treatment of steel structures should be as follows:
1.1.1 Surface of new ordinary steel structure
After the steel structure surface is sandblasted and derusted, a matching anti-rust and anti-corrosion coating is applied. It is recommended to use an epoxy zinc-rich primer + epoxy mica iron intermediate paint system.
1.1.2 Galvanized steel surface
In order to ensure good bonding performance with fire retardant coatings, epoxy coating transition paint must be used before construction.
1.1.3 Old steel structure or old primer surface
If the primer is not damaged and the surface is clean, check the compatibility of the fire retardant coating and the primer; if there is no primer or the primer is seriously damaged, the anti-corrosion coating must be removed and repainted before construction.
1.2 Before construction, thoroughly check whether the steel parts are painted with anti-rust paint, whether there is dust or oil, and check whether there are cracks in the steel beams and columns. 1.3 Steel parts that have not been rust-proofed must be rust-proofed (this process is generally performed by User is responsible).
2. Apply fire retardant paint
2.1 When opening the packaging on site, you must use an electric stirrer to stir until the consistency is uniform. If the material is too thick, add a small amount of matching diluent until it is suitable for brushing, but it should not exceed 5% of the paint volume.
2.2 This coating can be applied by brush, roller or spray. Each pass should be applied alternately horizontally, vertically and horizontally to ensure it is even and smooth.
2.3 Construction temperature and humidity requirements
When applying this paint, it should be used between 5~35℃ and relative humidity ≤80%. High humidity or low temperature will prolong drying time and cause poor film adhesion and reduction of other properties.
2.4 The coating thickness during the first pass of construction shall not exceed 0.2mm.
2.5 After the first coat is basically dry, apply the next coat until the specified thickness is reached. The dry film thickness of each coat should not be greater than 0.3mm (wet film 0.2-0.4mm).
2.6 Under normal temperature conditions, the construction interval should be more than 24 hours; if the temperature is too high or too low, the construction interval can be adjusted appropriately. If the temperature is greater than 20°C and the airflow is above 2m/s, you can generally apply two coats a day.
2.7 During the use of this product, it is recommended to use alkali-free fiberglass cloth for wrapping. When the coating is constructed to a thickness of about 1.2-1.5mm (dry film), wrap the alkali-free fiberglass mesh cloth with an overlap of 5-10cm. , after adding the mesh, use a spatula to compact the mesh in one direction, and pay attention to the compaction of the corners and joints. The next construction can only be carried out after comprehensive compaction and ensuring that there are no hollow parts.
2.8 High humidity and low gas flow or low steel temperature may cause condensation on the steel, resulting in poor adhesion of the paint, or even cracking, rolling, and peeling.
3. Surface coating construction
In order to improve the weather resistance and water resistance of the coating system, the top coat must be painted after the fire retardant coating is constructed. The top coat can be an acrylic polyurethane top coat, etc. The pre-construction paint must be checked for matching performance with the fire retardant coating.
3.1 When the fire retardant coating is basically dry, the matching topcoat can be applied.
3.2 When opening the topcoat packaging on site, you must use an electric stirrer to stir until the consistency is uniform. If the material is too thick, add a small amount of matching diluent until it is suitable for brushing, but it should not exceed 10% of the paint amount.
3.3 This coating can be applied by spraying, brushing, roller coating and other methods.
3.4 Apply 2 coats of topcoat to completely seal the fireproof coating.
3.5 Before applying the topcoat, the fire-retardant coating is strictly prohibited from being soaked in rain for a long time.
4. Construction steps and operating points:
1. Substrate treatment 2. First coat of paint 3. Second to nth layer construction 4. Self-inspection
Precautions
1. In order to improve the fire-resistant stability of the fire-retardant coating on key parts of the steel structure during a fire, it is recommended to wrap high-strength fiberglass cloth during the construction process.
2. In order to increase the overall durability of the fire-retardant coating system and prevent the fire-retardant coating layer from directly facing erosion from the external environment, our company requires that two anti-corrosion layers with good sealing effects must be constructed on the surface of the GT-WRP-Fp-WCB fire-retardant coating coating. Topcoat.
2. The temperature during transportation and storage of this coating shall not be lower than 5℃.
3. It is strictly prohibited to add other ingredients to this coating, and it is not allowed to be mixed with other coatings.
