Shading wallpaper refers to the phenomenon where the color of the surface beneath the wallpaper shows through, altering the perceived color of the wallpaper itself. This typically occurs when thin, light-colored wallpaper is applied over a darker surface.
Understanding Shading in Wallpaper Applications
Shading happens because wallpaper, especially thinner varieties, isn't completely opaque. Light penetrates the wallpaper and reflects off the underlying surface, influencing the overall color you see. The darker the surface beneath, the more it affects the final appearance of the wallpaper.
Causes of Wallpaper Shading
- Thin Wallpaper: Thinner wallpapers offer less coverage and are more susceptible to shading.
- Light-Colored Wallpaper: Light shades of wallpaper are more likely to reveal the color underneath compared to darker, more pigmented papers.
- Dark Substrate: Applying wallpaper to a dark-colored wall or surface increases the chances of shading. The greater the contrast between the wallpaper and the substrate, the more noticeable the shading effect.
Solutions to Prevent Wallpaper Shading
- Prime the Wall: Apply a primer to the wall before wallpapering. A white or light-colored primer provides a neutral base, preventing the underlying color from showing through.
- Paint the Wall: If you're applying light wallpaper to a dark wall, paint the wall a color similar to the wallpaper. This reduces the color difference and minimizes shading.
- Use Thicker Wallpaper: Choose a thicker, higher-quality wallpaper that offers better opacity and coverage.
- Wallpaper Liner: Apply a wallpaper liner to create a smooth, even surface and block the underlying color. This acts as a barrier, preventing shading.
Example Scenario
Imagine applying white wallpaper to a dark blue wall. Without proper preparation, the blue color will likely bleed through, giving the white wallpaper a bluish tint. Priming the wall with white paint or using a wallpaper liner can prevent this shading effect.
In summary, shading wallpaper is when the color of the wall beneath the paper affects the look of the wallpaper itself. This is most common with thin, light-colored papers applied over dark surfaces. Preventing shading requires proper wall preparation and the use of quality materials.
