Additional Information


  • 3/4″ thick
  • 3-1/4″ face width

Accoya Porch Flooring can be painted, stained or sealed with a clear top-coat to weather to a natural gray.  If staining is preferred, need to use an exterior grade water-based stain/sealer with a mildewcide or fungicide.

Guidelines on installation:

  • Must use Stainless Steel hardware.
  • If using against treated lumber, will need to apply a plastic barrier between Accoya and the treated lumber to eliminate the woods from touching.  A self-adhesive deck wrap works nicely.
  • Make a 1/4″ spacing at all hard adjacent surfaces in preparation of any expansion.
  • Coat all 6 sides before installation.
  • Allow proper porch ventilation to improve appearance and reduce possible swelling (recommended but not required). Openings in skirting should be 1/3 of area and the joists should be 8″ above grading.
  • Airflow Requirements: openings in skirting should be 1/3 of area.  Grade to bottom of joists should be greater than 8″.
  • Use a high quality exterior-grade sealer, stain or primer with a PH level of 9 or below.
