Why Is It Important to Prime Before Wallpaper Installation?

When you’re ready to change a room’s look with wallpaper, it’s important to do the job right. Using wallpaper primer is an important step in the installation process—without it, your wallpaper won’t perform as expected and may start to peel or bubble, damage your walls, or be difficult to remove. Learn why wallpaper primer is necessary and why it’s so important to prime before wallpaper installation.

What Is Wallpaper Primer?

Wallpaper primer is specially designed to be applied to your walls before you install wallpaper. It has a lot in common with paint primer—it’s a liquid that comes in a can and is rolled onto your walls. Unlike paint primer, though, wallpaper primer ensures your wallpaper can adhere to the wall correctly and protects both your wall and the wallpaper from damage. 

How many coats of primer you need depends on the type of primer and the surface you’re priming, so be sure to consult the instructions for your wallpaper and the primer.

Ensure Good Adhesion

The primary function of wallpaper primer is to help it properly adhere to the wall. Whether you’re installing wallpaper over drywall, paint, or existing wallpaper, primer provides the ideal surface to ensure your wallpaper adheres well and won’t peel or bubble. Wallpaper adhesive won’t stick well to everything, so it’s important to prime the wall with a product made just for that purpose.

Protect Your Walls

Wallpaper primer protects your wall by forming a protective layer between the adhesive and the wall. Unfinished drywall can absorb wallpaper adhesive, damaging the drywall. Wallpaper adhesive can also soften latex paint, leading to a soft, sticky mess that doesn’t properly dry under the wallpaper.

Make Removal Easier

When it comes time to remove your wallpaper, you’ll be glad you used primer. By creating a barrier between the wallpaper and your wall, primer prevents the adhesive from bonding too strongly to the wall. When you try to remove wallpaper bonded directly to the wall’s surface, there’s a good chance you’ll end up taking part of the wall off with the wallpaper. Primer leaves the wall intact and makes the removal process a lot smoother.

DIY vs. Hiring a Pro

If the prep process seems too involved for you to tackle as a DIY project, hire a pro who installs wallpaper to get the job done right. A local wallpaper installer will prep and prime your walls, giving you a flawless finish and wallpaper that’ll look great for years to come. 

Wallpaper installation costs an average of $1 to $7 per square foot, plus the cost of the wallpaper. Whether you’re wallpapering an entire room or just making a wallpaper accent wall, a wallpaper installation pro will ensure you get the best results.
