This 20 Mil Silverback is the best. It sealed the floor and prevents thing underneath from penetrating it.

Not cheap, but very good product. You get what you pay for and one proof of that, is that it is quite heavy to work with, especially for big pieces in tight places.

The materials were of high quality and worked as advertised. I used the 20 mil SilverBack over 5100 42.
