Why it’s Important to Waterproof Durock?

  • Durock is a special material made from a combination of cement and fibers. Doing this will help make sure your surface stays protected and dry.
  • One of the reasons why waterproofing durock is important is because it prevents the growth of mold and mildew. These can cause significant harm, particularly in humid or damp environments.
