Orange peel (paint)
Encyclopedia
Orange peel is a certain kind of finish that may develop on paint
ed and cast surfaces, even screen protectors. The texture resembles the bumpy surface of the skin of an orange (fruit) hence the name.
Gloss paint sprayed on a smooth surface (such as the body of a car
) should also dry into a smooth surface. However, various factors can cause it to dry into a bumpy surface resembling the texture of an orange
peel. The orange peel phenomenon can then be smoothed out with ultra-fine sandpaper
, but it can be prevented altogether by changing the painting technique or the materials used. Orange peel is typically the result of improper painting technique, and is caused by the quick evaporation of thinner
, incorrect spray gun setup (e.g., low air pressure or incorrect nozzle), spraying the paint at an angle other than perpendicular, or applying excessive paint.
In some situations, such as interior house paint, the orange peel texture is generally desirable. In this case, a texture paint is generally applied with a spray gun. The texture is then painted over with the appropriate color. When painting walls, orange peel can also develop by using a roller
with too little paint or too thick a paint and the surface dries before the texture can level.

Paint roller
A paint roller is a paint application tool used for painting large flat surfaces rapidly and efficiently.A paint roller typically consists of two parts: a "roller frame," and a "roller cover." The roller cover absorbs the paint and transfers it to the painted surface. The roller frame attaches to...
