HANGING FROM THE PAINTING
One of the problems that we can find during a painting process on vertical surfaces are the hangings of the paint.
These hangings or drains, are layers with excess product that by the effect of gravity, when applied on vertical surfaces, tends to drain downwards adopting the appearance of tears. This type of defect can appear in both paint and varnish applications.
WHAT ARE THE CAUSES?
1. Excess dilution or use of a solvent that is too slow.
2. Application of an overloaded layer.
3. The direct intense sun causes a surface drying and a consequent subsequent runoff of the paint on vertical surfaces.
4. Uneven distribution of the finish by gun.
5. The use of an inappropriate pitch nozzle, projecting excess film.
HOW TO PREVENT THEM?
1. Use the appropriate diluent according to the type and temperature of the surface to be painted (according to the technical sheet).
2. Not so much paint should be applied to the surface.
3. Avoid application to strong sunlight or give thinner layers.
4. Perform the application by moving the gun with regular and parallel movements.
5. Use the step nozzle indicated in the data sheet.
