View Full Version : Painting cardboard help

I need your expertise. I'm making space decorations for my Sons bday party. To minimize cardboard from warping when painting, should I prime both sides of cardboard at same time? Or can I prime one side, then the other after drying? Thanks in advance! 😎

If you prime both sides, you will have to hang-dry them. That is an option but I always do one side at a time with stuff like this myself.
