Hi all.

What is the most efficient and best way to apply polyurethane to a floor. I saw those large sponge brushes with the long handle on it to do it fast and it looked like it was nicely done to. Is this or what other better way is there to do it and also where can I buy it online. This is an important question to me though cause I have alot of polyurethane to apply and the faster the better. Thanks
