Wallpaper and Mural Installation
For installing wallpapers or murals is necessary to apply them on flat walls (plastered), with no finish or texture, otherwise plaster will have to be applied to the wall where the product will be installed.
The wall must be completely dry, otherwise wallpaper could wrinkle or grums or fungus may appear or even unstick.
Wallpapers can be applied in kitchens, preferably of vinyl class for an easier cleaning. Is not recommended to install wallpapers over ovens. Also, they can be installed in restrooms without showers to avoid humidity by vapor.
Step 1: Preparing materials and tools
- Chopper or cutter
- Measuring tape
- Metalic ruler
- Contact adhesive (e.g. Resistol 5000, No más clavos, etc.)
- Enamel Paint
- Metylan (multi-purpose surfacer, NO Redimix)
- Spray gun
- Metric leveler
Step 2: Preparing the base
The wall where the panels are going to be installed must be flat and clean from any particles.
Wall preparation: Before installing the product on the wall, fill with plaster any hole caused by nails, etc.
Step 3: Installing the product
Draw grid lines on the wall according to the size of each selected panel before positioning and cutting the product. Preferably start from the center of the wall and try to install the panel on flat walls, without switches or contacts or any other orifices that may exist.
The installer has to follow the specifier design. As a design suggestion, consider that you have to avoid cutting the panels so the product is completely viewed.
Important: Clean your hands and use gloves before installing the product to avoid spots on the panels.
Apply the contact adhesive to the wall with a clean brush and distribute it at the back of the product, specially at the borders. Don't apply adhesive in the front of the product. Let it dry for 5 - 15 minutes until your hands don't stick and put the panel on the previously drawn grid.
Tap gently the panel corners so it can be set on the wall and let it dry.
Step 4: Joints
Cover the joints with Metylan to get a complete wall effect. You may have to repeat this step.
Important: Let dry at least 1 day.
Step 5: Paint
Use the spray gun to paint. It must be enamel paint for a satin finish.
If automotive paint is used, you must use primer first.
Give one hand of primer first so the product doesn't absorb too much paint and let it dry, if required, sand the wastage with surfacer, 400 soft sandpaper and repeat step 4 if required.
Important: Don't sand the panel if it doesn't have a layer of primer or enamel paint.
Restrain as much as needed to get uniform joints.
Important: If the painted color is dark, put a Sayer Lack polyurethane layer.
Give 2 or 3 hands (or as much as needed) with spray gun or brush with enamel paint. You can use SUMMA from Berel paints and reduce it with 1090 reductor as the supplier indicates. You must be careful to let dry each hand of paint before applying the next one, otherwise the panel may be get humid. You can paint with new brushes of camel hair so the paint flows through reliefs.
Panels must be perfectly joined and leveled.
Panels must be align as close as they could to each other with 1-1.5mm joints which you must filled with Metylan.
Follow the design sequence of the panel design. If the cut is small, consider to install the product centered from the wall (specially if the wall is curved or misaligned).
Use a knife or cutter for cutting the wallpaper. Draw the line where you plan to cut and cut many times until the cut is made.
Don't stick it directly to the concrete or wall without paint.
If there are left cuts from the borders of panels and reliefs are visible, fill with paper and Metylan, making a flat finish as the wall border.
If you wish to paint the panel with other color, you'll have to sand it first and then paint it with the desire new color.
If you make cuts at the panels at the end of the wall, you can cover them with a frame or plywood, aluminium or any other material as shown in the following image.
