How to Put Wallpaper on Plastic?

Published in Wallpaper Application 3 mins read

Applying wallpaper to plastic can be challenging due to its inherently smooth surface, which offers insufficient adhesion for traditional wallpaper paste. However, for rigid and flat plastic surfaces, SmartStick peel-and-stick wallpaper is the best option.

Understanding the Challenge: Why Plastic Resists Wallpaper Paste

Plastic's non-porous and often slick surface is not ideal for wallpaper paste. Unlike drywall or wood, plastic does not absorb moisture from the paste, nor does it provide the necessary texture for the paste to grip effectively.

  • Smooth Surface: As stated in the reference, "Because of its smooth surface, plastic does not provide sufficient adhesion for wallpaper paste." This means traditional liquid adhesives struggle to form a strong bond.
  • Flexibility and Curves: The difficulty is compounded if the plastic is flexible or has a curved surface. The movement of flexible plastic or the contours of a curved surface can cause traditional wallpaper to peel or buckle over time, even if a temporary bond is achieved.

The Best Solution: SmartStick Peel-and-Stick Wallpaper

When dealing with rigid and flat plastic, self-adhesive wallpaper, such as SmartStick peel-and-stick wallpaper, emerges as the most effective solution. This type of wallpaper comes with its own adhesive backing, eliminating the need for external paste and bypassing the adhesion issues common with plastic.

Benefits of Peel-and-Stick Wallpaper for Plastic:

  • Self-Adhesive: No need for traditional wallpaper paste, which doesn't adhere well to plastic.
  • Stronger Initial Bond: Designed to stick directly to smooth surfaces.
  • Easier Application: Often repositionable during application, simplifying the process.
  • Removable: Many peel-and-stick options are designed for easy removal without damaging the surface, making them ideal for temporary updates or rented spaces.

Application Steps for Peel-and-Stick Wallpaper on Rigid, Flat Plastic:

  1. Prepare the Plastic Surface:
    • Clean Thoroughly: Wipe down the plastic with a mild detergent and water to remove any grease, dust, or dirt. Rinse completely and allow it to dry fully.
    • Ensure Smoothness: Make sure the plastic surface is completely smooth and free of any bumps or debris, as these can show through the wallpaper.
  2. Measure and Cut:
    • Measure the dimensions of the plastic surface carefully.
    • Cut the peel-and-stick wallpaper to size, adding a small allowance (e.g., 1 inch) on each edge for trimming.
  3. Apply the Wallpaper:
    • Start by peeling back a small portion of the backing paper from the top edge.
    • Align the wallpaper with the top edge of your plastic surface.
    • Slowly peel down the backing paper while simultaneously smoothing the wallpaper onto the plastic with a smoothing tool, squeegee, or a clean cloth. Work from the center outwards to push out any air bubbles.
    • If you encounter bubbles, gently lift the wallpaper and re-smooth, or use a pin to prick a tiny hole and press the air out.
  4. Trim Excess:
    • Once the wallpaper is fully applied, use a sharp utility knife and a straight edge to trim any excess material along the edges for a clean finish.

Summary of Solutions for Wallpapering Plastic

The effectiveness of wallpapering plastic largely depends on the type of plastic and the wallpaper used.

Plastic Type Adhesion Challenge Recommended Wallpaper Option
Rigid & Flat Smooth surface, insufficient adhesion for traditional paste SmartStick peel-and-stick wallpaper
Flexible / Curved Smooth surface, insufficient adhesion, material movement/contours Not recommended for traditional wallpaper; peel-and-stick may still struggle with flexibility.

While traditional wallpaper paste is unsuitable for plastic, SmartStick peel-and-stick wallpaper provides a viable and effective method for transforming rigid and flat plastic surfaces.
