The Modern Edge Z Counterform is ideal for cast-in-place concrete countertops where a reverse bevel edge profile is desired.  90" Full Package -  includes eight - 90" pieces (60 linear feet) and eight - 90" backwall pieces (60 linear feet). 90" Half Package -  includes four - 90" pieces (30 linear feet) and four - 90" backwall pieces (30 linear feet).   To use, place 1/2" cement board (Durock or Hardie Backer) on top of the cabinets and held in place with silicon caulking. **With this profile only, you will want to overhang the cement board 1/2" past the front of the cabinets. This will make sure that the drawer fronts do not protrude past the concrete edge.** The forms will then be screwed into the cement board with a 5/8" x #10 panhead screw . After the concrete is poured, the forms are snapped off along the designated "break point" to reveal a beautiful clean edge.   For more detailed instructions and advanced techniques, please watch our Full Instructional Video .**If using Ikea Sektion or other frameless cabinets, please see our resources here for more info.
