Hanging wallpaper in corners, especially inside corners, can be tricky due to their angles and irregularities. Proper hanging technique is key for a seamless, professional finish—ensuring the pattern aligns and avoiding gaps or overlaps between the adjacent wall and the other wall. To hang wallpaper properly, apply wallpaper paste and make a relief cut when necessary to help the paper fit snugly into right angles. When tackling the next strip or the last strip near a corner, knowing how to manage edges and alignment makes all the difference. With the right approach, papering corners becomes much easier and delivers a polished result.

Why Wallpapering Corners Requires Special Attention

When wallpapering corners, it’s important to handle internal and external ones differently. For internal corners, wrap the first piece of paper around the corner and overlap it slightly with the next strip to ensure the edges meet perfectly. For external corners, like on pillars, hang two strips carefully to avoid tears or gaps. Stretching the paper too tight or leaving excess can cause uneven edges. Pay close attention to the width and length of your paper to avoid misaligned patterns, as they are especially noticeable on external corners. These top tips cover several points to help you achieve a perfect finish every time!

Step-by-Step Guide: How to Wallpaper Internal Corners

When it comes to hanging wallpaper in internal corners, proper technique is crucial for achieving a seamless and professional finish. In this step-by-step guide, we will walk you through the process, offering tips and instructions to help you achieve outstanding inside corners.

Measuring and Cutting the Wallpaper

To measure wallpaper, use a tape measure to record the wall's height and width, including switches or outlets, and add a few extra inches for adjustments. For corners, measure to the adjacent wall and cut a longer strip to wrap and overlap. Use a straightedge and utility knife for clean cuts. Apply paste evenly to the back of the paper, position the strip, and align it with the corner. Smooth out bubbles with a wallpaper smoothing tool and trim the excess for a neat finish. When you get to the last piece, take the measurement carefully to ensure it fits perfectly. For stripes or patterns, align the paper in the middle to create a seamless look. Push the edges together when joining two pieces to avoid gaps. Work from the top down with vertical drops and ensure horizontal alignment for consistency. Repeat until the room is complete, and don’t worry—patience and precision make all the difference!

Applying Adhesive and Positioning the Wallpaper

Mix the glue thoroughly for a perfect texture.
Cut a longer strip of paper to overlap at the corner for a seamless finish.
Apply glue evenly to the back of the paper, covering the entire surface and edges.
Position the wallpaper on the wall, starting at the top and aligning it with the corner. Smooth it out with a tool, working from the center to the edges to remove bubbles.
Check alignment and adjust using a level or plumb line to keep it straight.
Trim excess paper at the edge with a utility knife for a clean finish.

Smoothing and Adjusting for a Clean Finish

To apply wallpaper smoothly and avoid bubbles:

Prep the Wall: Clean the surface, fix cracks, and remove loose paint or debris.
Apply Adhesive Evenly: Spread glue evenly on the back of every piece to prevent bubbles.
Smooth from the Center: Use a tool or cloth to press from the center outward, removing bubbles.
Check Alignment: Use a level or plumb line to keep it straight.
Trim Excess: Cut extra wallpaper along the edges with a sharp utility knife for a clean finish.

Step-by-Step Guide: How to Wallpaper External Corners

Wallpapering external corners can seem challenging, but with the right techniques, you can achieve seamless and professional results. In this step-by-step guide, we'll walk you through the process of how to hang wallpaper smoothly and wrinkle-free. Start by cutting a length of paper slightly longer than needed, then carefully push it into the corner. Wrap the drop around the edge, leaving enough to overlap onto the other side. Add another piece of paper on the other side, aligning it carefully for a clean finish. Finally, smooth the wallpaper as usual, and remember to add extra patience for perfect results!

Preparing the Corner Surface

For professional results before hanging wallpaper in external corners, start with perfect, clean walls:

Smooth Wall Corners: Fix bumps or cracks with spackling paste, then sand for an even base.
Clean Surface: Remove dust, dirt, or grease with a mild detergent and sponge to ensure proper adhesion.
Reinforce Corners: Apply extra glue or primer along the corner for a stronger bond. Let it dry fully before installing.

These steps will help you get a flawless finish on external corners.

Wrapping the Wallpaper Around the Corner

Getting perfect alignment and patterns when wrapping paper around corners is essential for a polished look. Here are some tips:

Measure and Mark: Measure the corner's width and mark the center to align the design.
Overlap: Hang the first strip on one side of the corner, slightly overlapping onto the next wall. Align the pattern for a seamless finish.
Trim Excess: Smooth the paper, remove bubbles, and cut any extra with a sharp knife.
Double-Cut: If designs don’t match, cut through both wallpaper layers, remove the excess, and smooth the seam.

Securing and Sealing the Wallpaper Seams

Using a seam roller is key to achieving a professional look with peel and stick type. Follow these steps:

Apply Even Pressure: After placing the wallpaper, roll along the seams with even pressure to ensure proper adhesion.
Work from the Center Outward: Start rolling from the center of the seam and move outward to eliminate bubbles and wrinkles.
Repeat the Process: Roll over each seam, applying consistent pressure.

Tips to Prevent Peeling

Prepare the Surface: Ensure the wall is clean, dry, and dust-free before applying wallpaper. A flat surface helps it stick and prevents peeling.
Avoid Overstretching: Don’t overstretch the wallpaper during application, as this can weaken the adhesive. Align strips carefully without pulling too much.
Secure the Edges: Use a cloth or smoothing tool to press down the edges, especially in corners, for a strong bond.

How to Do Corners with Peel and Stick Wallpaper

Achieving seamless corners when you hang wallpaper is essential for a professional-looking finish. To master the art of installing wallpaper on inside corners, start by applying wallpaper paste to ensure a secure hold. Measure the next wall carefully and cut the wallpaper strip to the right length. Use a tool to press the paper firmly into place, ensuring no bubbles or wrinkles.

Key Differences from Traditional Wallpaper

It is more flexible, allowing for easier installation around corners, curves, and uneven surfaces, which can be challenging with less adaptable materials. Additionally, its strong adhesive ensures a secure bond, eliminating the need for extra glue or paste, and saving both time and effort during the application process. This makes it a versatile and convenient choice for various projects.

Step-by-Step Process for Internal and External Corners

When installing peel-and-stick wallpaper, proper positioning is key for a seamless finish. Here are some tips for even application:

Measure and Plan: Measure your wall and calculate the wallpaper needed. Use a level and pencil to mark guidelines for accurate placement.
Start from a Straight Edge: Align the first one with a straight edge, like a corner or door frame.
Peel and Stick Carefully: Peel off the backing slowly and press the strip to the wall, smoothing out air bubbles with a squeegee or cloth.
Adjust if Needed: If needed, gently lift and reposition the strip without damaging the glue. Even out wrinkles or bubbles as you go.
Overlap and Trim: Overlap edges slightly for a seamless look and trim excess paper at corners and edges with a sharp knife or scissors.

Common Challenges and How to Overcome Them

Misaligned Patterns and How to Fix Them

Misaligned patterns with peel-and-stick wallpaper can be frustrating. To fix, peel back the strip, reposition it, and align the design with the adjacent one. Carefully match the designs and smooth out wrinkles or air bubbles for a seamless look.

Dealing with Uneven or Old Walls

Uneven or old walls can make wallpaper application tricky. Fill holes or cracks with spackling paste and sand smooth. For textured walls, apply a primer to create an even surface. Clean, dust-free walls ensure better adhesion and a smooth finish.

Conclusion

Achieving a professional look with peel-and-stick wallpaper is easy with the right prep and care. Here’s how:

Align Patterns: For patterned wallpaper, align with adjacent strips for a seamless look. Smooth out wrinkles and air bubbles as you go.
Prepare Walls: Fix holes or cracks, sand smooth, and use a primer on textured walls. Clean thoroughly to remove dust for better adhesion.
Take Your Time: Go slow. Align designs, smooth wrinkles, and ensure proper adhesion. It might take a couple of tries, but practice makes perfect.
