Priming walls before applying wallpaper involves treating the surface with a preparatory coating. This coating creates an ideal substrate for the wallpaper adhesive, ensuring a strong and lasting bond. Consider a freshly painted wall: its smooth, potentially glossy surface might resist the wallpaper paste. Priming mitigates this, offering a more receptive texture.
Proper surface preparation contributes significantly to the longevity and appearance of the finished wallpaper. It improves adhesion, preventing peeling, bubbling, and seam separation. Furthermore, priming seals the wall surface, preventing the absorption of adhesive into the drywall or plaster. This ensures the paste remains effective in bonding the wallpaper and also simplifies future wallpaper removal. Historically, various methods were employed to prepare walls, but modern primers offer a consistent and reliable solution.
