How to measure your wall
All you need to do is to measure the width and the height of the complete wall. We always produce your wallpaper in the exact measurements you specify when ordering, so we recommend you to add 5 cm (2 inches) to the measurements, both width and height. For tips on measuring different wall types please see the cases below.
Standard walls
Measure the width and the height of the complete wall. Please double check to make sure you get it right. We always produce your wallpaper in the exact measurements you specify when ordering, so we recommend you to add 5 cm (2 inches) to the measurements, both width and height.
Sloped walls
Measure the wall on the highest and widest point, ignoring any slopes. The mural will be printed and delivered as a whole rectangle or square and the sloped part is cut away during installation. We recommend you to add 5 cm (2 inches) to the measurements, both width and height.
Multi-sloped walls
Measure the wall on the longest part in both with and height. The mural will be produced as a whole rectangle or square and the sloped part is cut away during installation. We recommend you to add 5 cm (2 inches) to the measurements, both width and height.
Walls with doors, windows or other obstacles
Measure the width and the height of the complete wall. All obstacles will be cut out during installation. We always produce your wallpaper in the exact measurements you specify when ordering, so we recommend you to add 5 cm (2 inches) to the measurements, both width and height.
Multiple walls
Measure the width of each of your walls and combine these measurements into one when ordering. Add 5 cm (2 inches) per wall as a safety margin. Then measure the height. Always start from the highest point and also add 5 cm (2 inches) to that measurement. You don't need to order the mural as two separate parts.
Staircases
As with other sloped walls, please identify the highest and lowest point of the wall when measuring the height. The same goes for the width. All sloped parts will be cut away during installation. We recommend you to add 5 cm (2 inches) to the measurements, both width and height.

Preparation
1. Make sure the surface is smooth and clean
Remove any old paint or wallpaper that is coming off. Clean the surface and apply filler where necessary. If the surface is porous, please apply a primer/mist coat or prepaste before papering. Porous surfaces include skimmed walls, walls with old wallpaper, particle board or similar. If you hang our premium murals on a dense surface that does not absorb moisture, it may take several days for the paste to dry, as our premium papers are not as breathable as our standard ones. You should also prime the surface if it has bright colours that could show through the wall mural.2. Mix wallpaper paste from Happywall (not included)
Fill a clean bucket with 4 litres (1 US gallon) of lukewarm water and slowly add the paste powder while stirring briskly. Leave the paste to stand for 5 minutes and stir again. The paste is now ready to use. The paste should be nice and thick, so don’t use more than 4 litres (1 US gallon) of water when mixing. If you do add more, the wallpaper may not fix properly. One bag is enough for around 20-22 m≤. If you are using ready-mixed wallpaper paste, use a paste for non-woven wallpaper or one for woven wallpaper with <20% dry content.Hanging
1. Check the wallpaper
Before hanging, make sure no panels are missing and none have any defects or damage. The panels are numbered at the top in the order they should be hung. Hang from left to right.2. Make sure the panels are hung straight
It is vital that the first panel is hung straight. It is a good idea to draw vertical markings one panel width (50 cm) in from the corner using a spirit level, a measuring tool and a pencil. Use the markings as a guide to hang the rst panel. Make sure the markings are faint so they don’t show through the wall mural.3. Apply the paste directly to the wall
Use a roller or a brush. It’s important to cover the whole area with paste – an unpasted spot will create a blister in the wall mural. Apply the paste approximately one panel width in advance.4. Hang the panels edge to edge
The panels should not overlap. Take care to press the panels together firmly at the seams – use a seam roller for the best results. Be careful to match up the pattern with the next panel, and avoid getting wallpaper paste on the front of the mural as this will show when it dries. Note: Avoid harsh folds as this may cause cracks in the print.5. Smooth down the panels from the ceiling to floor
Use your hands or a wallpaper brush, starting from the middle and smoothing out towards the edges. Any small bubbles and folds will disappear once the wall mural has dried. If there are any spots of paste on the front of the wallpaper, use a damp cloth or sponge to remove them, but avoid rubbing.6. Trim off any excess paper
Once all the panels have been hung, trim off any excess paper using a trim guide and a sharp knife.Wait 24 hours to see the finished results

Prep your wall
Using a damp cloth or sponge, clean the surface with warm water and mild soap. Allow the walls to dry for a minimum of 24 hours. While cleaning your wall take the last opportunity to finally check: is this a smooth surface? Orange peel, knockdown or a rough wall will make the peel&stick wallpaper challenges to adhere to the wall, if the surface is not smooth we recommend the conventional non woven wallpaper with paste the wall glue. Have you freshly painted walls before application, preferably a light uniform colour if it differs significantly from your wallpaper as dark patterns / colours may show through. You should give your walls 4-6 weeks to fully cure completely.At the same time as cleaning the wall
Lay flat all your tiles as the wallpaper might have a curl memory from the roll. We recommend at least 24hrs to be flat and climatized in the same room as intended for installation.Hanging wallpaper 1-5
Start by dividing the lengths as indicated by the cutting symbols. Lay the lengths flat, with the label facing upwards, in numerical order starting with length number 1. Make sure you have all the lengths and that none of them are defective or damaged. 2–5. The lengths are numbered in the order in which they must be hung. The lengths should be hung edge to edge without any overlapping. It is essential that the first length is vertically straight. Tip: Make a pencil mark one wallpaper width along the wall near the ceiling. Hold a plumb line on the mark and draw a vertical line down the wall. Then line up your first length of wallpaper with this pencil line. 2 & 3. Peel the paper from the backing about a third at time, smooth with your hands as you go. Find your own way, we recommend working from middle Make sure your panels are not overlapping and are put seam-to-seam. If your panel is not perfectly positioned, do not worry, you can carefully rear down the panel and reposition it again. Finally when you have your panel(s) on your wall, use the squeegee and smooth out all possible air between the panel and your wall to make the wallpaper adhere to the wall. Once all the wallpaper has been hung, cut off any excess along the ceiling and floor. Always use a sharp blade to avoid tearing the paper. Enjoy the result!
