How to spray water-based paint in cold weather

When using water-based paint spraying in low-temperature environments, we need to pay attention to the following points:

Temperature control: Low temperature environment will affect the drying speed and quality of water-based paint. Therefore, when choosing the spraying time, we should try to avoid low-temperature periods. It is best to spray when the temperature is between 10℃ and 30℃. If the temperature is too low, the drying time of water-based paint will be extended, which may affect the quality and adhesion of the coating film.

Preparation before spraying: Before spraying with water-based paint in a low-temperature environment, make sure the surface is clean, dry, and free of dust, oil and impurities. Because the moisture in low-temperature environments may form frost during the painting process, reducing the adhesion and quality of the coating film. In low-temperature environment, we can use a fan or heater to blow or heat the surface in advance to ensure that the surface is dry.

Choice of diluent: The choice of diluent for water-based paint in low temperature environments also requires attention. The addition of diluent will affect the fluidity and coating property of the film. In low temperature environment, it may be necessary to add an appropriate amount of warm water for adjustment to improve the fluidity and coating properties of the paint film. Please confirm that the thinner used complies with the specifications and instructions for water-based paint.

Spraying skills: When spraying in a low-temperature environment, we need to pay attention to controlling the speed and thickness of spraying, and try to avoid problems such as dripping, wrinkling, and poor leveling. Short distance and multiple spraying methods can be used to ensure that the paint film is uniform and dries quickly. For example, Gimlanbo’s light industrial equipment waterborne paint and other water-based paints can be sprayed in this way. At the same time, we also need to pay attention to using the appropriate nozzle size and spray pressure.

Drying time: Due to the long drying time of water-based paint at low temperatures, it is recommended to appropriately extend the waiting time after spraying to ensure that the coating film is fully dry. At the same time, we should also pay attention to avoid exposure to wet environment during the drying process, otherwise it may affect the quality and adhesion of the coating film.

Finally, according to the specific water-based paint product and usage instructions, as well as the working environment and requirements, we still need to refer to the detailed guidance on the product and operate according to the actual situation. If necessary, we can consult professionals or manufacturers for more accurate operating advice.
