What does "back rolling" after spraying paint refer to?

Back rolling after spraying paint refers to the technique of using a roller to smooth out and ensure an even application of paint over the surfaces that have been sprayed. This method serves multiple purposes, including closing up the texture created by the spray process, helping to level out the paint film, and removing any potential drips or runs that may have occurred during spraying.

The benefit of back rolling is that it can enhance the overall finish, allowing for a more uniform appearance and improved adhesion of the paint to the surface. This step is particularly important when working with thicker paint products or when applying a finish where a smooth texture is desired.

In contrast, using a brush for details refers to a different technique that allows for precision work, but does not address the smoothing aspect of back rolling. Applying a second coat is related but not specifically tied to the concept of back rolling, as that involves layering paint rather than refining the initial application. Finally, rolling paint before spraying is not a common practice and would not facilitate the same benefits as back rolling after spraying, as it does not address the smoothing of the sprayed layer.
