I'm working on a project and I'm still not so sure regarding the difference between stains and polyurethane. Which one to use? Or do I use both? I mean from the name itself, stain is for color right, but is this required to have? Then polyurethane what is it? What does it do? Are they used together if they're different?
 
Stain adds color, while polyurethane is a protective finish. You can use both , the stain first for color, then polyurethane to protect the surface from wear, moisture, and UV damage

Well well,, stain is not actually required, but it's often used for aesthetic reasons. Polyurethane, on the other hand, is a protective finish. It seals the wood and shields it from moisture, scratches, and wear.

let me add that polyurethane is a clear, colorless, protective coating that forms a hard layer over the wood. It's essentially liquid plastic that cures into a tough film
 
It's a great combo, the stain goes first, let it dry about 24 hours and then add the poly and let that dry. This is the best approach to get the perfect look and protection.
