painting over knockdown texture
 

What is the best method for painting walls with knockdown texture. I have a small wagner power painter sprayer(2400 psi model) and i also have rollers and brushes. I would like to spray it if i can, mostly walls and a couple soffits. If i can spray it should i go behind the sprayer and roll the walls after i spray them? Any advice on painting these walls will be much appreciated. Thanks

I'm not a painter by trade, but I would just use a 3/4" nap roller. I believe the pros who reply will recommend back-rolling after spraying, so why have to clean up the sprayer??
