Common Issues and Prevention Strategies in Water-based Paint Spraying

In the last issue, we discussed choosing a water - based furniture paint spraying production line. Now, let's talk about common issues in water - based paint spraying and their solutions.Water - based paint is popular for its environmental friendliness and good painting results. But during application, we must note some key points to get a perfect finish.

Oil - based Primer and Water - based Topcoat Process

When using an oil - based primer and water - based topcoat, separate the gun pumps and paint buckets for oil - and water - based paints.Moreover, before spraying the water-based paint, the oil-based primer must be completely dry.

Environmental Control

When spraying water-based paint, the working environment needs to be well controlled. The temperature and humidity in the drying room and the spray booth have a significant impact on the painting effect. The ideal temperature is 25 - 35°C and humidity around 40%.

Paint Selection

Some wrongly think water - based paint is costly and hard to handle. In fact, many mature manufacturers are in the market. Pick the right one, and you can control costs while ensuring quality. The paint recovery system, with a straight - path tank to prevent sediment and an easy - to - clean design, also saves thinners.

Construction Details

Viscosity is crucial. Too high, the gun may clog; too low, the coating may sag. Adjust viscosity according to the situation. Water - based paint uses water as a solvent, but different products have different mixing ratios. Read the manual carefully. Filter the paint before spraying to remove impurities and ensure a smooth coating.

Following these tips can prevent common problems like swelling, delamination, and ensure the best painting effect.
