13 Dec Bona Underlayments
Bona’s underlayments reduce the noise of floor traffic and give the floor a softer, more exclusive feel. They can also be used as a problem solver on concrete floors with cracks and weak, porous surfaces. The latter problem is quite common and widespread among many old floors.
Bona offers three different types of underlayments: U300, U310 and U340 which you can read about in the attachment.
