Installation Instructions

Firstly; Remember to take  a ‘before’ photo!

Choose Your Wall

Pick a smooth, dry and clean surface. The surface must be sound, completely clean, smooth, dry, free of any contaminates such as dust, dirt, grease, or migratory agents that can reduce film adhesion, prior to wall art application.

The most traditional places include any wall, door, window or car (do not block wind shield). When placing your wall art on a standard painted wall, make sure the wall has been previously primed prior to painting (otherwise the paint may come off). If you place your wall art on a pebbly, textured surface that has used eggshell paint or a very porous surface (i.e. brick, cement walls, stucco), you may receive poor results, although it has worked in some cases on newly painted surfaces. Make sure you allow 30 days on newly painted surfaces for out gassing to prevent bubbling. We also suggest avoiding placement above fireplaces. We recommend using a liquid lamination or clear coat for longevity.

Not recommended for brick, non-painted cement surfaces, or heavy painted spackled wall board.

It is important to repair any wall damage before applying your wall art to return it to a like new condition. A wall that is not properly repaired could cause poor graphic adhesion or additional wall damage during removal of the graphic.

Examples of an unsound wall surface include; loose paint, damaged surface, cracks, or inconsistent surface (texture), holes in walls, loose wall board joints, too much texture in the paint (the surface may be smoothed down with sandpaper or scouring pads & walls must be primed and painted after this is completed), paint chipped, loose, flaking or peeling, moisture behind the wall board (Pay attention to areas prone to condensation such as walls surrounding cooling units, water pipes, overhead windows, or any water pipes that could drip on the graphic), dust, dirt, or vehicle exhaust contamination on the wall, wallpaper that is not surely bonded to the wall in all areas (it is recommended that graphics not be applied over wallpaper) contamination by other products on the wall that was not properly cleaned & cuts made to the graphic during the installation that penetrates both the film and the substrate.

Clean Your Wall

Use a warm, damp cloth or sponge to clean the wall surface or window and allow it to completely dry. Make sure all previous cleaning solutions are completely gone. Outdoors we suggest you use a pump spray to save time. You can remove and replace the wall art multiple times; however, once the adhesive collects too much dust, dirt or fibres it will become less effective and the wall art may not stick as well to your surface.

For most interior painted drywall surfaces simply wiping down the substrate with a clean lint free towel will be sufficient. However, some surfaces may require extra cleaning. If the surface is greasy using a solution of trisodium phosphate (TSP), mixed according to the manufacturer’s directions may be necessary (TSP can be purchased at most hardware stores)

For other surfaces remove all dirt and grime with a commercial synthetic detergent solution and warm water (2 drops per litre). Avoid detergents with lotions, waxes, creams, or oils. Be aware some window cleaners have waxes.

Smooth poured concrete walls or concrete block walls (interior only); It may be necessary to clean with a power washer or hand wash with a stiff brush and detergent and rinsed with clean water. Dry the surface with clean, lint-free paper towels – for at least 24 hours before graphics are applied. Brush the surface immediately before application to remove any dust or dirt that may have collected during the drying period.

Textured Walls; Too much surface texture allows adhesive contact only with the high points of the wall, which does not provide sufficient contact for a proper application. In some cases a cast film with an over laminate can be used on these surfaces. Using a heat gun and rivet brush to work the film into the crevasses. Textured walls can be smoothed down using sandpaper or a scouring pad. After sanding the wall must be properly primed, painted and cured before the graphics are installed.

Peel & Stick It Your Wall Covering

Before starting the application use masking tape to temporarily tape up all panels to ensure graphic size, position & hinging technique. When handling the graphics be sure to hold the film as far into the graphic as possible, without wrinkling the film. This will help avoid transferring oil from fingers and dirt to the edges of the graphic, which could result in peeling edges or lifting, which can cause eventually adhesion problems.

Use two hands when pulling the liner from the film, using care not to stretch the film. Always remove the liner from the graphic rather than the graphic from the liner.

Depending on the size of your wall art, it may be helpful to have two people install it. Try not to let the adhesive come together or let your wall art fold up against itself. It’s okay if it does, you can separate it by carefully pulling it apart and you may want two people to do this on larger images. Start at the top of your wall art image and pull down approximately 4-6” of the backer and crease the back of the backer. Simply apply the 4-6” of exposed adhesive area to your chosen location. It can be repositioned many times.

Our wall coverings start with the middle panel. Draw a line at the width of the wall panel and vertically plumb. We recommend hanging the first panel in a part of the wall without doors or windows. Start by placing the first panel at the top, using the marked lines to align with the top of the wall or at the level you’ve marked for your wall art.

Once your square then continue to slowly pull the backer downward in 4-6” increments, smoothing the wall art as you go. Depending on the size, it may be helpful if one person pulls down the backer, while the other smooth’s the image on the surface. You can use a plastic dry wall knife (like 6”-8”) to smooth out. If there are any bubbles or wrinkles, you can lightly press or smooth them out, or just peel back that area and re-apply. Please Note: Pressing too hard will not damage the wall art; however, it may cause your hands to gather ink (due to the natural oils on your hands), and could transfer from your hands onto another surface.

Pull the squeegee or rivet brush across graphic. Pushing it will cause the film to stretch. Move the squeegee or rivet brush in a straight line-not in an arc. Initially use light to medium pressure with overlapping strokes, taking care not to stretch the graphic and lose printed image registration between print drops and overall image.

Once the graphic is applied firmly re-squeegee all of the graphics particularly the edges to ensure good adhesion. Trim graphics 3-6mm from the inner and outer wall corners. Finish the graphic by working a rivet brush in small circles around the entire outer 75mm of the graphic. Apply wall graphics using the dry application method for adhesive wall coverings. Water or application fluid can cause damage to the wall and cause premature graphics failure if used on the adhesive material.

Once the first panel is correctly hanged, start hanging the following panels, taking as a reference the first panel and its cross-hair marks. Panel should overlap by 1cm, make sure that you match the 2 cross-hair marks at eye level. Smooth down the wall covering in the same way you did the first one.

Trimming & Finishing

Cut away excess material around an object. Using a straight edge, push the panel flush against the wall and into the joint/intersection between the wall and your door or window. Use a sharp knife to remove any excess print. The knife must be sharp to prevent tearing. You should have approx. 25mm at base and on the end panel. When trimming around switch plates, ensure all switch have been removed. Firmly smooth wallpaper and crease into the top of the switch. Make a hole in the wall covering where the centre of the fitting is with a Stanley knife. Remove the wall covering surplus from the fitting. Mount the cover again.

Suggestions

If a bubble re-appears over the next day or two, pressing and lightly rubbing can remove it. This can happen occasionally if oil, dirt, or dust is on your surface. You may also use a pin to pop the bubble, and then smooth it out with your fingers in a circular motion. In the very rare instance that it keeps re-appearing, you may want to move your wall art to another area as there is something wrong with this surface.

Graphic Removal

Our Wall Coverings can be removed and reused within reason. If you plan on reusing your covering keep the backing paper to use for storage once removed. My Wonder Wall does not warrant damage to the interior wall surface caused by removing film even if a removable adhesive was used. Removing a graphic can cause damage to the wall. This is especially true if a permanent adhesive is used. Due to the variety of wall surfaces My Wonder Wall cannot guarantee damage free removal. The amount of damage can be reduced or eliminated by following the inspection, cleaning and preparation guidelines.

Removable adhesives are designed to make the film removal clean and easy within a warranted period. The removability of a film may vary depending on the substrate and how it was prepared. (Permanent adhesives are designed to provide optimum adhesion to a variety of substrates. They are generally difficult to remove and may cause damage to some wall surfaces. Films with permanent adhesives are a good choice for textured wall surfaces)

For best results remove slowly. Most graphics are easier to remove from a textured surface than a smooth surface since there is less adhesive contact. Clean removal from any painted wall board may be not be possible, even when using a removable film. If the bond of the film to the paint is greater than the bond of the paint to the wall board, the paint and possibly the paper covering on the wall board could be damaged during graphic removal. Moisture that has penetrated wall board will destroy the painted surface when graphics are removed. Remember that, especially in remodelling jobs, wall board may have been placed over windows, cooling pipes, etc., that may produce moisture that is transferred to the wall board.

Start at the top of the graphic and pull it away from the wall at a 120-180 degree angle. Do NOT use chemicals for interior wall graphic removals. Heat may be used if the substrate is not wall board. If the substrate appears stained after graphic removal, it is usually the caused by poor quality paint, exposure to heat and light, migrating particles in the paint, and adhesive residue. To make removal easier graphics can be cut into 12-24” strips. Take care not to cut the surface underneath.
