Re: Can someone explain what polyurethane is for?
First and foremost, Minwax makes great stains, but their poly and other top coats are absolute garbage!!!!
Polyurethane is a clear finish that has replaced lacquer and shellac because of it's more environmentally friendly. There are different types/grades of poly, make sure you're using one rated for floor use before applying or you're going to have a huge mess on your hands when the coating fails.
Not sure what your stain is capable of without knowing more about it. Some stain products are a stain and top coat finish all in one. These are a poor choice for most projects, particularly a floor because the stain is held within the top coat finish like a paint, rather than a penetrating stain. What is the exact brand and product description of the stain you used?
