There is a variety of trendy patterns and colors of wallpapers to choose from. Layering the wall with coats of paint and stylish wallpaper is trending these days. But you need to ensure the condition of your walls before installing wallpaper. Moreover, you can use an acoustic wall lining system along with wallpaper to increase sound insulation.
For preparing your wall before installation, remove all décor. And move away the furniture or anything that might get in your way. Then repair any cracks, dents, or damage. You can use a spackle for this purpose. After repairing the wall, use sandpaper to smooth the wall. Then wash the walls with soap and a sponge to get rid of dirt and let the wall dry completely.
After that, primer the wall because it’s necessary for the protection of your walls. It will prevent over-adhering off the wallpaper to the surface of the wall. After applying primer, let the wall dry completely. And when you are done with these pre-requisites, you can install wallpaper. And here is a step by step guide that will help you in the installation of wallpaper on painted walls.
Step 1: Measuring the Walls:
The first step is to measure the walls by using a measuring tape and a level. Measure the height and width of each wall and record the measurements. Then use a plumb bob tool to draw a plumb line at the midpoint of the wall.
Step 2: Calculate Number of Sheets:
After calculating the height and width of the walls, calculate the number of wallpaper sheets you need. And divide the width of the wall by the width of the wallpaper roll to get the actual number.
Step 3: Cut the Wallpaper roll:
To cut the wallpaper roll, put the front side of the wallpaper down on the table. And decide where you want to start the design. Then mark the starting point on the back but leave at least 4-inch extra wallpaper. After that mark the length of the wall on the wallpaper and cut along the mark.
Step 4: Cut the Wallpaper Strips:
Cut the whole wallpaper roll by using the first strip as a guide. It will make sure that all the strips are of the same length and width. But always remember to leave the extra paper at the top and bottom.
Step 5: Pre-Pasted or Not Pre-Posted:
If your wallpaper is pre-pasted, you don’t need to put any adhesive. But if it’s not pre-pasted, apply even layer of adhesive with a high-quality roller.
Step 6: Hanging the Wallpaper:
Take your first wallpaper strip and paste it against the plumb line. Then press the wallpaper gently and you can use a putty knife for this purpose. And if you are using patterned wallpaper, carefully select the next strip. Moreover, carefully release any bubbles and wrinkles.
Step 7: Trim the Excess:
Gently move downward while pasting the wallpaper and once you reach the bottom, trim the excess wallpaper. You can also gently pull the wallpaper back and form a crease on the excess wallpaper. Then cut it by scissors.
Step 8: Remove the Excess Adhesive:
After trimming the excess wallpaper, remove the excess adhesive with damp sponge. And repeat the same procedure for the rest of the strips.
