Liquid Latex and Dry Brushing

I was just somewhat curious, does liquid latex mixed in with acrylic paint have any benefits? I didn’t use any on my masks before and didn’t see anything wrong, but that was when I applied heavier coats of dry brushed paint onto my masks. Now that I’ve worked on a Kills and Ends mask with lighter and gradually thicker layers of paint, I noticed it has more of a grainy feel, but still no cracks yet. Thoughts?
