Have you ever sprayed paint with a air atomizing or HVLP gun before? If so, it's the same method. You don't ever hold the gun in one place, but sweep back and forth until you gave the coverage you are looking for. With paint, you do this with multiple coats. With texture, it is done in one coat. That one coat however means that you spray an a wall and spray it imediately again if you want more texture on it. You don't wait for it to dry and then spray again like paint. Make sense?

Later........I have to build a DVD rack today.
