HOw do you stain wood moldings evenly?
First you need to be sure all of the surface is sanded evenly and is smooth. Woods like pine have varying porosity and therefore tend to blotch. You need to use a stain pre-conditioner first. I would use the pre-conditioner on all molding before staining. If you are trying to stain finger jointed moldings, they are made up of many smaller pieces of various types of wood and really shouldn’t be stained. That type of molding is called “paint grade” because it is only suitable for painting and not staining. Finally a gel stain that is designed to stay of the top surface of the wood and not penetrate can used to give a more even color. It can also be applied over other stains to help you blend the light and dark areas. The method you use to apply the stain is not as critical as how you prepare the wood and the type of stain you use.
