Question:

Why can't you use steel wool with polyurethane?

I am refinishing a table and on my can of polyurethane, it indicates not to sand with steel wool prior to application. Why is that?

Answer:

Steel wool will leave invisible pieces of metal embedded in the finish, no matter how much you try to wipe it off. When you cover it with the polyurethane, it is trapped and turns dark over time, ruining the look of the table. Yeh, so follow the directions exactly for the best finish. Good luck!! : /
