Hey guys, here's a great recent product development. A replacement for Durock backer board, which has to be cut with a circular saw. The cloud of dust makes it impossible to work inside and the label warns of cancer causing silicate agents if inhaled. Now that really sucks. Dens Shield backer board has a great design for the contractor or home owner looking for a better, easier installation of backer board for tile finishes. The face consists of a thin rubber layer that is both moisture resistant and provides a strong hold for thinset and ceramics. It has a light weight, rigid aggregate core that can be cut with a regular drywall knife, unlike other backer boards on the market. I have used it on walls and floors in bathroom remodels and showers and it has withstood the test of use and time.
