The Applications


INTERIOR CEMENT BOARD SYSTEMS

Walls, Bathtub
Installation
  • Cut Smartboard to required sizes and make necessary cut-outs.
  • Fit the ends and edges closely but not forced together
  • Stagger end joints in successive courses
  • Fasten Smartboard to studs
  • In double layer walls where Smartboard is installed over base-layer gypsum board, a water barrier is required over the gypsum board.
Walls, Shower Receptors
Installation
  • Smartboard is fastened to studs in a straight plane to within 1" of the bottom of shower pad or waterproof membrane
  • When using a molded or precast shower receptor, it should be installed so that the edge of the Smartboard sits on the lip of the receptor.
Fill the space between the edge of the Smartboard and the receptor with flexible sealant.

Floors, Interior
Subfloors
  • Apply multi-purpose adhesive to center of top flange of joists.
  • Place exterior grade plywood sheets on joists.
  • Fasten plywood to joists with adhesive and suitable nails or screws
 Smartboard Panel Application
  • Laminate 7/16" Smartboard to subfloor.
  • Smartboard then must be fastened to subfloor with wood screws or galvanized roofing nails.
  • Allow 1/8" wide space between panels to be filled solid with dry-set or latex-portland cement mortar. For best results, joints should be taped.
Walls, Interior
Installation
  • Smartboard panels are scored and snapped to desired dimensions
  • When installing Smartboard over solid backings, the fasteners must be long enough to penetrate the solid backing and anchor to the approved setting materials.
