Replacing wallpaper in a home or building is a project that requires planning and careful preparation. The first and most important step is to evaluate the condition of the existing walls and the old wallpaper. If the wallpaper is peeling, damaged, or outdated, then it clearly needs to be removed. Before starting the actual work, you should gather all the necessary tools such as a wallpaper scraper, utility knife, sponge, bucket, ladder, and drop cloths to protect the floor. It's also a good idea to move furniture away from the walls and cover everything to avoid stains or damage. Proper preparation ensures that the rest of the process goes smoothly from start to finish 建設業 働き方改革.
The next important step is removing the old wallpaper. This part can be time-consuming depending on how long the wallpaper has been on the walls and how strongly it was glued. Some wallpapers come off easily, while others need to be soaked first. You can spray the surface with warm water or wallpaper removal solution to loosen the adhesive. Once the wallpaper is soaked, use a scraper to gently peel it off. In some cases, multiple layers of wallpaper may be present, requiring additional time and effort. It is important to be patient so as not to damage the drywall or plaster underneath while removing the old material.
Once the old wallpaper has been removed, attention turns to cleaning the walls. Any leftover glue residue or small pieces of paper should be completely cleaned off. This can be done using a sponge or cloth dipped in warm water mixed with a little soap. After cleaning, let the walls dry completely. Inspect the wall surface for any cracks, holes, or imperfections. These should be filled with joint compound and sanded smooth to create a clean, even surface for the new wallpaper. A smooth, well-prepared wall ensures that the new wallpaper will adhere properly and look professional.
The next step is to apply primer or wallpaper sizing to the walls. This prepares the surface and makes it easier to hang the new wallpaper. Priming helps the wallpaper stick and also makes it easier to remove in the future if you decide to change it again. Some people skip this step, but professionals usually recommend it to get the best result. Wait for the primer to dry completely before proceeding. During this time, you can unroll the new wallpaper and measure each strip based on the height of the wall.
Measuring and cutting the wallpaper accurately is very important. It's best to cut the wallpaper strips slightly longer than needed to allow for adjustments at the top and bottom. Make sure the patterns align if you are using patterned wallpaper. Apply adhesive to the back of the wallpaper or use pre-pasted wallpaper that just needs to be soaked in water. Fold the wallpaper strip onto itself (this is called "booking") to activate the glue and make it easier to carry and install. Let it sit for a few minutes according to the manufacturer’s instructions.
Now comes the stage of hanging the wallpaper. Start at the top of the wall and press the wallpaper strip onto the surface, working from the center outward to remove air bubbles. Use a smoothing brush or plastic smoother to flatten the paper and ensure it sticks evenly. Make sure that the edges are aligned perfectly, especially if you are matching patterns. Continue with the next strip, being careful to place it edge-to-edge with the previous one without overlapping. Repeat the process across the entire wall, trimming the extra lengths at the ceiling and baseboard using a sharp utility knife.
After all the wallpaper is hung, inspect the entire surface for any bubbles or loose edges. Use a seam roller on the seams where two strips meet to press them down and secure them firmly. Wipe off any excess adhesive with a damp sponge before it dries, as dried glue can leave a visible shine or mark on the wallpaper. Let the wallpaper dry completely, which might take several hours or even overnight depending on the type of wallpaper and adhesive used. During this time, avoid touching or placing furniture too close to the walls.
In the final stage, step back and examine the finished result. A freshly wallpapered room can dramatically change the atmosphere of a space, making it look updated, clean, and stylish. Replace any outlet covers or switch plates, and move furniture back carefully. Properly maintained wallpaper can last for many years. Cleaning it occasionally with a soft cloth will keep it looking new. Replacing wallpaper may seem like a challenging task, but with patience and the right steps, it can be a very rewarding home improvement project that makes a noticeable difference in the appearance of a home or building.
