How do I install a wall mural? - Paper wall mural

Notes:

- Although the wall mural is made of high-quality material, the wet panel must be handled gently to avoid tears.

- Remember that each print has limited resistance to mechanical wear.

- Subsequent panels are pasted in the same way by pasting them with a 15 mm overlap. This means that each mural panel overlaps the previously pasted panel by 15 mm. Please note: if the panels are pasted edge to edge, the pattern will be out of line.

- It is very important to allow the paste to soak into the subsequent panels for an equal length of time. Soaking for a longer or shorter period may result in the panels having different lengths, resulting in the patterns being out of line.

- If a panel begins to roll up, it means that it is not sufficiently soaked with paste.

- After hanging, the edges of the panel can be subject to the most tension, and also dry more quickly because they are at the edge. It is also possible that less paste is applied around the edges. METYLAN paste (in a tube) can be added to improve adhesion at the edges.

- Remember that it is not possible to completely avoid the joint overlap effect at the point of contact. Suitable preparation of the design and choice of image may help.

- It is recommended that nothing be stuck on a new wall for a month, so that the wall can dry thoroughly. Make sure the paint on the wall does not reduce bonding strength.

Preparing the wall:

Proper surface preparation before hanging the mural is very important and essential for good results. This stage must therefore be carried out with the utmost care.

- The prepared surface must be low-absorbent, clean, dry, smooth and free of dust and remnants of any pigments which could stain the mural.

- Remove old wallpaper. Old paint layers that partially or wholly cover the wall and which could make it difficult for the paste to penetrate the wall must be removed.

- All damage, scratches and unevenness must be filled and then smoothed with sandpaper. Then the wall must be cleaned with water and degreaser.

- Dry mouldings, plasterboard and walls that are too porous or absorbent must be treated with a primer. Prior to application of the primer, check whether the product you are using has been absorbed properly and has not merely formed a layer on the wall.

- If you are not sure whether the wall requires primer, apply it anyway as a preventive measure.

- Plastered walls: before pasting the mural, check if the surface is dry.

- The bases of any newly-plastered walls can be neutralised with a primer.

- On walls that have been previously painted with emulsion paint, a thin layer of wallpaper paste should be applied with a brush or a roll to the area where the mural will be hung. Wait until the wall is completely dry. This treatment prevents the adhesive from being absorbed too quickly into the wall, and therefore helps when positioning the mural and removing air bubbles and ripples.

- Do not hang murals on wet surfaces. Wait until the walls are completely dry. If you do hang on wet walls, there is a risk that the mural will not adhere properly and that mould might develop.

Preparation of the wall mural:

Before pasting, check the condition of the wall mural.

In order to check the condition of the mural and make sure it meets expectations, place the panels next to each other on a clean dry floor with the printed face upwards. If the mural is composed of a number of panels, make sure the pattern is correct, and that the colour and thickness of the different components do not vary at the joints.

Pasting:


 

1. Begin hanging by defining the position of the mural panels on the wall. We recommend that you start at a window and work towards the door. Before hanging the first mural panel, mark the position of the edge by drawing a line with a pencil. It is important that these lines be drawn accurately. This avoids any problems with previously pasted panels shifting position.

     
 

2. When the wall has been properly prepared, lay the first mural panel on a large table. Place it with the image side down and apply a thick layer of paste with a roller or brush. Make sure that the edges are well covered. Do not cover more than one mural panel with paste at a time. Fold up the mural panel carefully so that the paste is on the inside and the entire surface covered with glue is not visible and not in contact with the open air; this could cause it to dry.

Be careful not to crease the mural. This might be visible after pasting the panel. IMPORTANT: the mural must be folded in such a way that all the surfaces covered in paste touch each other. In other words, it should not be possible for the pasted surface and the image surface to come into contact with each other when the panel is folded up.

     
 

3. Leave the folded-up panel for 5 minutes so that the paste can soak in properly. During this time, the panels will swell, which can result in the panels becoming approximately 1 cm wider. Do not leave the mural for too long, otherwise the layers might stick together. While waiting, a layer of paste can be applied to the wall, which will make it easier to hang the mural.

4. After 5 minutes, unfold the panel, and place the pasted side against the wall. Ideally, this should be done by two people. Each person secures two corners of the panel so that it can be placed precisely against the wall. Adjust the pattern exactly to the previously pasted panel.

     
 

5. All edges are professionally cut and should overlap 15 mm. This means that each section of the mural is applied 15 mm on top of the previously applied section. Please note: if the panels are placed exactly next to each other, the pattern will not line up.

     
 

6. Next, smooth the surface of the panel with a rubber roller and ‘push’ air bubbles away by shifting them towards the edge of the panel (do not puncture air bubbles). The panel edges have a tendency to come loose. To avoid this, make sure that the edges of the various panels are well stuck, preferably by using a hard roller to press the panels firmly to the wall. If the paste on the wall is dry but the edges are still coming loose, apply another layer of paste to the edges and press them firmly against the wall again with the roller.

     
 

7. Remove excess paste with a clean damp sponge. Do this after application of each panel of the mural, before the paste can dry. Never scrub more than once in the same place, and never use chemical cleaners. The drying paste can damage the surface of the wall mural.

     
 

8. When hanging subsequent panels, it is very important that the amount of time that the paste is allowed to soak in remains the same. If it is allowed to soak in for a longer or shorter period, the length and width of the panels may vary and the pattern will not line up.

9. Remove air bubbles with a rubber roller.

10. Trim the top and bottom edges of pasted panels with a sharp knife.

Prachtig resultaat in een heel goede kwaliteit. Het plaatsen verliep vlekkeloos. Ik lees dat de afhandeling van de bestelling niet alleen bij mij wat moeite heeft gekost, maar het was uiteindelijk het wachten waard!
