The Do’s and Don’ts of Wallpaper Primers

Applying wallpaper is a great way to add style and personality to a space, but to get the best results, using a primer is key. Wallpaper primer creates a smooth, clean base on the wall, making it easier for wallpaper to stick and stay in place. Here’s a simple guide on the do’s and don’ts of wallpaper primers to help you avoid common mistakes and ensure a professional finish.

The Do’s of Wallpaper Primers

1. Do Choose the Right Primer for Your Wall Type
   Different primers are suited to different wall surfaces. For drywall, choose a primer-sealer that blocks stains and creates a smooth base. For previously painted walls, a high-quality primer that bonds well is a good choice. Always check the primer label to see if it matches your wall type to get the best adhesion and results.
2. Do Clean and Prep the Wall First
   Before applying primer, make sure the wall is clean, dry, and free from dust or grease. Cleaning removes any residue that might interfere with the primer and wallpaper sticking properly. Fill any holes or cracks, sand rough spots, and ensure the surface is smooth. A clean, well-prepped wall ensures the primer will go on evenly, creating a solid foundation for your wallpaper.
3. Do Use a Roller for Even Application
   Using a roller allows for a more even application of primer across the wall compared to a brush. Rollers also cover more surface area quickly, which saves time. For best results, use a roller with a short nap (the thickness of the roller cover), as this helps spread the primer thinly and evenly without texture.
4. Do Let the Primer Dry Completely
   Patience is essential when applying primer. Allow the primer to dry fully according to the instructions on the can (usually 2–4 hours). Dry primer prevents the wallpaper from peeling or bubbling and helps it stick firmly to the wall. Rushing this step can lead to issues down the road, so take your time.
5. Do Use a Wallpaper-Specific Primer
   Not all primers are suitable for wallpaper. Use a primer designed specifically for wallpaper installation. Wallpaper primers have special formulas that create a slightly textured surface, making it easier for wallpaper to stick. Avoid standard wall primers, as they may not offer the best grip for wallpaper.

The Don’ts of Wallpaper Primers

1. Don’t Skip the Primer
   Skipping the primer can lead to many issues, including uneven adhesion, peeling wallpaper, and even damage to your walls. Primer ensures the wallpaper stays in place and makes removal easier if you ever want to redecorate. Without primer, the wallpaper may not adhere correctly, especially on painted or previously wallpapered walls.
2. Don’t Apply Primer Too Thickly
   A thick layer of primer can create an uneven base and may even cause the wallpaper to peel. Use a thin, even coat of primer, spreading it carefully to avoid dripping or clumping. Too much primer can create a glossy surface, which is harder for wallpaper to stick to, so keep it light and even.
3. Don’t Forget to Ventilate the Room
   Wallpaper primers often contain chemicals that can cause strong fumes. Open windows, use fans, or wear a mask to avoid inhaling these fumes, especially in smaller rooms. Ventilating the room will make the priming process more comfortable and ensure that the primer dries properly.
4. Don’t Rush the Process
   Applying primer is a step that requires attention to detail. If you rush, you risk missing spots or applying the primer unevenly. Take your time to ensure the primer is fully covering the wall and is drying as it should. A well-done primer job sets the foundation for beautiful, long-lasting wallpaper.
5. Don’t Ignore the Primer Instructions
   Each primer has specific instructions, so don’t skip reading them. Some primers may require a second coat or a longer drying time, so follow the instructions to ensure proper application. Ignoring these guidelines could lead to problems with your wallpaper sticking or lasting over time.
