: S4S (Surfaced on 4 Sides) with a pre-sanded 180-grit face.

: A specialized US-standard gray primer applied to all six sides, specifically formulated to prevent the "tannin bleed" often seen in Western Hemlock when exposed to humidity.

This feature focuses on a specialized back-relief and moisture-barrier coating to improve the durability and installation speed of large-format 1x12 boards.

Here is a proposed feature set for a high-end or baseboard designed for the US market:

: A subtle "H" (High-relief) taper where the bottom edge is 3/4" thick for a sturdy floor transition, while the top beveled edge thins to 1/2" for a sleek, low-profile look against the drywall. Technical Specifications Material : Vertical Grain (VG) Western Hemlock. Dimensions : 0.75" x 11.25" (Actual US Standard for 1x12).
