Low temperatures can cause numerous issues during roof coating applications, such as extended drying times, frozen original coatings, prone to cracking paint films, and issues like water spots on the coating. However, spray application is a crucial step in the anti-corrosion and anti-rust process for genuine stone paint roofs. This highlights the significant impact of temperature on the corrosion resistance of steel tile roofs, which can even determine the success or failure of the construction acceptance.

What are the temperature requirements for applying water-based coatings?

Water-based coatings use water as the solvent. The critical temperature for water to freeze is 0°C. When the temperature drops below 0°C, the paint inside the packaging桶 may have frozen. Therefore, it is not recommended to rush or carry out construction during temperatures below 0°C or on winter mornings. If work must continue under these conditions, cracking and peeling may occur. If the water-based coating is not used up all at once, it must be stored in an environment above 0°C to maintain quality (seal the paint after opening and use it within one week).

What should be noted during the spray application?

Prior to construction, clear away surface obstructions such as dust, flaking rust, and paint peel.

To dilute, add 5% - 10% distilled or tap water, but do not exceed this amount; just dilute until it no longer drips.

Recommended construction temperature: 5~35°C, humidity: 30~70%.

④ Be sure to manage the construction time during winter, allowing ample time for the coating to self-dry. This will extend its service life.

After construction is completed, the equipment should be immediately rinsed with clear water.

⑥ After opening the packaging drum, it is important to ensure it is sealed properly to prevent evaporation that may affect its quality.

When performing weatherproof and anti-rust coating on color steel roof panels, it is crucial to pay attention to the weather and temperature. If outdoor work on color steel roof panels is interrupted by rain, please cease operations immediately. The appropriate working temperature range is between 5~35°C, with humidity between 30~70%. Construction should not be carried out in conditions of rain, fog, snow, or heavy dust, as these situations are associated with lower temperatures.

When the weather is moderate, carrying out anti-corrosion and anti-rust treatment on the color steel roof not only saves time and effort, but also yields very ideal results after construction.
