orange peel prevention?
I prime a lot of 1x poplar for prefabbed staircases. the boards are sanded to 80g and then the zinnser oil-based primer is applied with a 1/4" nap roller. After they dry they are sanded quickly with a DA orbital to get them a little smoother. Many times if the primer is applied too thick i will get an orange peel look which drives the finish painters crazy. For a quick fix I will just sand the primer a little bit extra until the surface is smooth. Is there any way to get a smoother finish without having to sand the heck out of them every time? Should i thin the paint..add penetrol?
