Spray paint art help?

okay, i've seen videos on youtube with spray paint art, like spraycasso. he's really good, he gives tips but i tried to write him a question but never answered. so i'm wondering if any of you can,





When you have ur paper (poster board mainly) before you begin with an actual color like blue or green or red, do you put a base coat before you even begin those? and in ur own opinion do you think it's a waste of time doing this (spray paint art)?Spray paint art help?
I think its a worthy way to make art. It depends on what you're painting if you put a base coat down. If you want the background to be the same color as your poster-board then don't put a base coat down. Otherwise, pick a color and spray it in the background. Then let it dry and start with the other colors. Hope this helped!Spray paint art help?
you normally do not have to but if you would rather a shiny finish put a base coat on.
