According to PipeDown :

Textured wall paint comes in several consistancies and can be applied with a
roller or sponge or hopper (air gun). Most paint brands also make a
texture.

Ick. I'd rather throw open paint cans at the wall.

I hate textured finishes. Impossible to clean or repair, and messy to repaint,
and they shed, sometimes even without touching it.

It's a _garage_.
