When staining a deck, you have several choices in the type of stain to use. There are transparent stain types, semitransparent stain types, semisolid stain types and solid stains. Transparent stains will soak into the deck boards while a solid stain is more like a paint and will rest on top of the boards. The type of stain you use, as well as other factors, will greatly determine how often you need to stain your deck. As a general rule of thumb, the newer the deck, the more transparent the stain.
