Now that your floor is nice and dry, it’s time to seal the deal with polyurethane. If you don’t know what polyurethane is, it’s basically a clear coat that will seal the stain and keep it protected. Without polyurethane, your taking the risk of the scratches reappearing. Exactly – nobody wants that!
As you may have guessed, application is going to be very similar to when we applied the stain. First, you need to take a bowl and pour the polyurethane into the bowl – just enough to coat the bottom. Now, instead of using a rag, you’re going to use a paintbrush. It’s much easier to apply polyurethane with a paintbrush.
