2. Safety & Board Preparation

CRITICAL LEAD PAINT WARNING

Assume the old painted side of the boards contains lead. DO NOT dry scrape, wire-brush, or sand the painted sides. Lead dust is incredibly dangerous in an open dome environment.

Step 1: Encapsulate the Back (Outside)

Work outside or on heavy plastic sheeting. Lightly mist the painted side with water, wipe away loose dirt gently with a wet rag (no aggressive scrubbing). Once dry, spray or roll a coat of clear matte polycrylic or lead-locking primer directly over the old paint. Let it cure.

Pro Tip: By sealing the paint on the back, you lock the lead away safely forever and prevent it from chalking off onto your drywall.

Step 2: Remove the Old Wallpaper

Flip the boards to expose the unpainted face with the stuck wallpaper. Fire up your clothes steamer.

  • Hold the steamer plate over the paper for 15-20 seconds to melt the 100-year-old starch glue.
  • Use a plastic putty knife (never metal, it will gouge the soft wood) to easily slide the paper off while hot.
  • Wipe the warm, gooey residue off with a warm, damp nylon dish sponge.
Pro Tip: Don't obsess over "ghost prints" (faint wallpaper patterns left in the grain). Once oiled/sealed, these historical shadows look amazing.

3. The Finish & "Colourflage" Prep

Pre-Finishing the Raw Face

You MUST seal the wood face before assembling the wall. If you oil it after assembly, the oil will bleed onto your painted tongues and ruin the crisp lines.

  • For a dry/natural look: Water-based clear matte polycrylic.
  • For a rich, dark amber look: 100% Hemp Oil or Tung Oil (wipe on, let soak, wipe off excess).

Painting the "Colourflage" Tongues

Once the face finish is completely dry, stand the boards on their grooved edge.

  • Tape off the front edge of the face if you are a messy painter.
  • Brush your bright, vibrant "colourflage" accent paints exclusively onto the protruding tongues of the boards.
  • Let them dry completely before installation.

4. The 3-Bay Chevron Installation

Why 3 Bays?

Because your boards are 5.5' long, running a single chevron across a 13-foot wall would require ugly mid-span butt joints. Dividing the 13-foot wall into three equal 52-inch bays ensures your boards span edge-to-edge seamlessly.

1

Blackout the Drywall

Paint the 4x13 drywall area flat black or a very dark color. As old wood naturally shrinks and expands, this ensures any micro-gaps look like intentional dark shadow lines, not bright white drywall peering through.

2

Mark Your 3 Bays

Measure the 13-foot (156") wall. Draw a plumb (perfectly vertical) line at 52 inches, and another at 104 inches. You now have three equal 52-inch work zones.

3

Set the 45° Angles

Start at the bottom center of the wall (the 78" mark).
- Bay 1 (Left 52"): Cut ends at 45°, angle boards upward to the left.
- Bay 2 (Center 52"): Angle boards upward to the right.
- Bay 3 (Right 52"): Angle boards upward to the left (matching Bay 1).

4

The Gap & Nail Technique

Apply a zigzag of Liquid Nails to the back of each board. Slide the groove over the painted tongue below it, but leave a 1/16" to 1/8" gap to let that bright color pop out. Shoot a brad nail at an angle through the top tongue into the drywall/studs to hide the nail holes completely.

You're Ready to Build.

Take your time with the math on the first few 45-degree cuts. Once the first bottom triangle row is set, the rest goes up incredibly fast.
