Wall Treatments and Vertical Finishes
Beyond standard drywall—mastering paint finishes, limewash, roman clay, and technical wallpaper installations
Wall Treatments and Vertical Finishes
Quick Summary: Walls represent 70% of the visible surface area in a room. Moving beyond standard flat paint to High-Sheen Finishes, Textured Plasters, or Technically-Applied Wallpapers can transform a space from "Generic" to "Master-Class." The key is matching the treatment's Durability to the room's Friction Level.
In Color Theory, we discussed hue. Here, we focus on Sheen and Surface. The way a wall reflects or absorbs light is the difference between an Art Deco Glamour and a Wabi-Sabi Sanctuary.
The Paint Sheen Hierarchy
Sheen is the concentration of resin vs. pigment. Higher resin = more durable and reflective.
| Finish | Reflectiveness | Washability | Best Room |
|---|---|---|---|
| Flat / Matte | 0-5% | Low | Ceilings / Adult Bedrooms |
| Eggshell | 10-25% | Medium | Living Rooms / Offices |
| Satin | 25-35% | High | Kitchens / Hallways |
| Semi-Gloss | 35-70% | Highest | Trim / Doors / Bathrooms |
| High Gloss | 80%+ | Highest | Accent Walls / Ceilings (Dramatic) |
Artisanal Textured Finishes
Textured walls add "Quietude" and visual interest without the need for additional decor.
Material: Crushed limestone and water.
- Effect: Mottled, suede-like finish with high depth.
- Pros: Naturally high-pH (antibacterial/mold resistant).
- Vibe: Mediterranean or Wabi-Sabi.
Material: Plaster with a smoother, clay-based finish.
- Effect: More "Cloud-like" and velvety than limewash.
- Pros: Extremely soft to the touch.
Material: Traditional lime plaster mixed with marble dust.
- Effect: High-gloss, "Stone-like" finish that can be burnished to a mirror-shine.
- High-End: Very labor-intensive but increases home value significantly.
Mastering Wallpaper Technicals
Wallpaper is a "High-Information" material.
Measure Twice, Buy Extra
Always purchase 15-20% more than you think you need. "Dye lots" change—if you run out and order more later, the colors may not match exactly.
Match the "Repeat"
Verify the Pattern Repeat (vertical distance until the pattern repeats). Large repeats result in more waste.
Choose the Right Substrate
- Non-Woven: Breathable and easiest to remove ("Paste-the-wall").
- Vinyl: 100% washable; mandatory for bathrooms and high-traffic hallways.
- Grasscloth: Natural, high-texture, but cannot be washed and shows "Seams" by design.
Level 5 Finish
Before applying thin, dark wallpapers, ensure the wall is "Level 5" (completely smooth). Any tiny bump in the drywall will "Telegraph" through the paper.
Key Takeaways
- High Sheen = High Durability (but shows flaws).
- Limewash is the "Organic" choice for texture.
- Vinyl wallpaper for wet zones; Non-woven for easy DIY.
- Measure by Dye-Lot: Never mix batches.
- Sound control starts with vertical surfaces.
