Painting your walls with a nice wall color is fun, but wallpaper can also be very beautiful. With wallpaper you can create a very specific atmosphere and appearance in an interior that you cannot achieve with any other wall finish. Many people dare to paint their own walls, while most are afraid to decorate their own walls. However, wallpapering is not a difficult job at all, especially with our handy tips and the extensive manual (including video). Goodluck!
1. Order all rolls of wallpaper in one go
Order all the rolls of wallpaper you need in one go. There is a chance that there may be differences between different productions, so that the result will not be a beautiful whole. You can see this by the batch or serial numbers. These must be the same. It is therefore also important to check this again at home, also for color differences, for example. With a wallpaper calculator you can easily calculate how much wallpaper you need. Click here .
2. Use lining paper
Consider hanging a paper lining on the wall before you start wallpapering. Lining paper ensures that you have a smooth, even surface, which makes real wallpapering a lot easier. Imperfections are well hidden, so that the end result will be even more beautiful. Applying lining paper is also a good exercise before you actually start wallpapering.
3. Hide misalignment
Apply a 2-3 centimeter strip of white paint to the top of the wall before wallpapering over a dark wall or one with old wallpaper. This way, it won’t stand out as much if your wallpaper isn’t exactly aligned at the top of the wall.
4. Get all the tools at home first
With the right tools and the right materials, wallpapering is a lot easier. Therefore, always collect all the necessary tools and the right materials before you start this job. We have listed this for you below:
- Wall filler and / or plasterboard;
- Seam filler;
- Wallpaper glue;
- Paint bucket;
- Fur roller;
- Block brushes;
- Putty knife;
- Wallpaper brush;
- Hobby knife;
- Tape measure;
- Carpenter’s pencil;
- Spirit level or plumb bob;
- Wallpaper table;
- Sponge and cloth;
- Seam roller;
- Wallpaper ruler.
5. Use plastic instead of newspaper
You can also rent a wallpaper table at one of the well-known hardware stores. Then you don’t have to buy one. Do not use newspapers to cover the wallpaper table. The ink from the wet newspaper can stain the wallpaper and make it unusable. Therefore cover the wallpaper table with a plastic tablecloth.
6. Use a spirit level to keep the wallpaper straight
The walls in the house are usually not perfectly straight walls. To ensure that your wallpaper is straight, it is wise to use a spirit level. Using a long spirit level, mark the perpendicular line on the wall with a pencil. Always check after the first wallpaper job whether it is actually straight.
7. Length of the wallpaper webs
Your first strip of wallpaper should be about four inches longer than the height of the wall. All other wallpaper webs should be at least two inches longer at the top and bottom. For wallpaper with a pattern, the wallpaper strips should be even longer than the first to ensure that the pattern fits well.
8. Lay cut wallpaper strips on the floor
After you measure and cut the first strip of wallpaper – and you know it’s the right size – lay it flat on the floor and measure the next strip. Make sure there is enough space at the top and bottom of the second lane for the cartridges to align correctly. You can use a pencil to label the back of the wallpaper if you are preparing several legs at once (the pencil marks will not disappear when the paper gets wet). Laying everything on the floor is much easier than trying to do it on the walls.
9. Turn off power to switches and outlets
Turn off the power in the room before hanging around switches and outlets. Wallpaper over the switches and outlets as if they weren’t there, creating a diagonal slit from opposite angles. Cut away the triangular flaps and replace the cover plate.
10. Check for imperfections early
Check all wallpaper jobs for bubbles and seams. Bubbles should be smoothed out as soon as possible and seams adjusted before the glue dries.
11. Remove excess glue
Use a sponge or damp cloth to wipe off any excess glue from the wallpaper, ceiling and baseboards. Make sure to rinse the sponge or cloth thoroughly and regularly to remove as much glue as possible so you can use it again.
12. Sharpen tools
Make sure your knife or scissors are sharp before cutting. Dull scissors can tear the wallpaper and lead to uneven lines. It is important when cutting with the printed side up. In this way, any errors can be detected immediately.
13. Carefully trim the paper
Hold a wide putty knife between the wallpaper and the knife while cutting. This protects the paper and ensures a straight cut. Also, don’t lift the knife until you are done with the cut.
An alternative way to trim wallpaper is to use the back of a scissor blade to mark the corners on the wallcovering. Then pull the paper away from the wall and cut it along the marked line with the scissors. Only try this if you can cut a straight line.
14. Use a special glue for edges
You will need a special glue if you plan to put a border on the wallpaper. Let the wallpaper dry for at least 48 hours before you hang the wallpaper border.
15. Room temperature
Just like with dyeing and painting, temperature also plays an important role when you are going to hang wallpaper. It is best to have a room temperature between 18-20 degrees. Close windows and doors so that the wallpaper can dry well and quietly. If this happens too quickly, cracks can appear in the wallpaper.
We have written out a handy manual for you, which explains step by step how to get started on the walls in a room. Also watch the Karwei video below to get a visual picture of it.
The walls must be clean, dry, healthy, straight and smooth. If you are wallpaper on plaster or wood, apply a universal primer the day before so that the wall has a good grip on the wallpaper. If you have glossy painted walls, sand them down and then apply a universal primer. If you have matte painted walls, wash them with a cleaning product containing baking soda and let the walls dry for 24 hours before wallpapering.
Now is the time to prepare the wallpaper glue. You can also use ready-made wallpaper glue. Refer to the manufacturer’s instructions.
Use a spirit level to trace a vertical line 50cm from the corner of the wall (if your roll is 53cm wide). This will ensure that you start wallpapering from a perfectly straight hanging mark and the remaining 3 cm will ensure that you avoid imperfect corner joints (if the corner is not straight). You can focus on this when you have finished wallpapering the entire wall.
Using a brush or roller, apply the wallpaper glue to the wall in a thin, even layer, starting from the vertical line you just traced, starting at the top and working your way down the width of a roll. Use stairs to get to the top of the wall.
Place the wallpaper roll on the floor, align it with the vertical line and roll it out to the top of the wall; keep 2-3 cm from the ceiling to allow a straight cut.
Place the wallpaper carefully against the wall and check the alignment of the track against the vertical mark. Once you are satisfied that this is straight, use a wallpaper brush to smooth the wallpaper from the center to the edges to smooth out any bubbles and wrinkles. If the track is not positioned the way you want it, slowly remove and reposition it.
Trim excess paper at the top and bottom with a utility knife and ruler, flatten the seams with a seam roller and repeat for the rest of the wall, making sure the seams line up each time.
To cover wallpaper around switches or outlets, cover it completely with wallpaper, then cut it away.
To paper the pieces of walls around doors and windows, cover the openings with the wallpaper strip, mark the corner with your finger and use the scissors to cut the excess paper. Make sure you leave a few extra centimeters on the window or door cupboard. Cut the wallpaper at a 45 degree angle to the mark to the left of your finger. Smooth it out with the wallpaper brush and cut off the excess paper with the utility knife.
Ideally, you remove the radiators before wallpapering, but if this is not an option, then that is not a disaster in itself. Measure the dimension from the ceiling or window edge to the radiator mounts and add 2 to 3 cm for the cuts around window frames and ceiling. If the wallpaper has patterns, add the length needed to align them with the adjacent strip.
Cut the required length of wallpaper with scissors, ruler and a utility knife and hang it on the wall. Smooth it around the radiator fixings.
To wallpaper the pieces around the pipes, apply the glue to the wall and measure and cut the piece of wallpaper you need. Place the wallpaper behind the pipes and smooth it out.
