🟢 What causes paint sagging, and which is its possible solution?
Causes and how to prevent the occurrence of sagging
1. Low viscosity in the paint mixture can cause sagging.
To prevent this this, add thinner to the paint mixture according to the specifications provided in the technical data sheet, maintaining a mixture viscosity that is in accordance with the temperature and humidity.
As pointed out, too much paint per coat will influence the appearance of sags.
It is advisable to apply even and uniform coats, trying not to overload the part on every layer.
2. Incorrect adjustment of the coating equipment, either due too low pressure or excessive product flow, can lead to sagging on the surface.
In addition, it is advisable not to apply the paint too close to the surface.
3. An appropriate distance must be kept between the spray gun and the support for an even distribution of the paint.
For the paint to adhere correctly to the surface and not to sag, respect the waiting time between layers established in the technical data sheet of the product, always taking into account the environmental conditions.
4. The use of heavy or slow solvents in low temperature environments may increase the chances of sagging appearing on the repaired part.
This is why it is important to choose a solvent that suits the type and context of repair.
