Sponge Painting

Last updated: April 3, 2019

What Does Sponge Painting Mean?

Sponge painting is a coating application technique that gives an interesting texture and appearance to a surface. To perform the sponge painting process, a paint-covered sponge is pressed against the substrate. Paint, glaze, a sponge and cleaning supplies are most of the required accessories for sponge painting.

Sponge painting is mostly used for cosmetic applications and is not typically used for corrosion protection or more industrially focused coating jobs. Part of the reason for this is because of the uneven coating distribution the sponge painting process provides. Although this patchy coating provides a unique aesthetic appeal, it is somewhat unreliable for protection from severe corrosive conditions.


Corrosionpedia Explains Sponge Painting

Sponge painting is very popular because it creates a unique pattern when compared with other coating techniques. The amount of paint applied varies across the surface area of the sponge. This creates a non-uniform layer. Also, the look of the sponge painting can be further altered by adjusting the amount of paint on the sponge and the pressure with which the sponge is applied against the surface.
