Prepare the supports
- Depending on the type of support and its old coating, plan a few hours before you start laying the future wallpaper.
- Walls should be properly prepared and sanded with the correct grit of sandpaper.
Wash with special detergent for walls then rinse. On a shiny and satin paint, sand with sandpaper so that the glue can hold.
New or porous walls
Apply an undercoat for plaster or pre-gluer 24 hours in advance. This protects the wall and allows the wallpaper to take off without damaging the wall.
Before you start
- Rolls should be inspected lengthwise before laying.
- Choose a glue adapted to the type of paper (vinyl paper, standard, etc.).
- During gluing and installation, keep a bucket of clean water and a sponge close at hand to remove traces of glue, clean the upholstery wheel or wash your hands.
- Dark colored wallpapers might need a tinted touch up of the edges to avoid a white line.
- Draw a vertical line 52 cm (i.e. a standard length minus 1 cm) from the door or the corner of the wall. This is the axis along which you will lay the first length
- Measure the height to be lined and add 10 cm for the leveling cuts at the top and bottom. Unroll a roll on the table and mark the length that has just been calculated.
- Fold the paper back on itself and mark the fold.
- Cut the length with scissors.
- It can also be cut with a cutter and a ruler.
- Stack the lengths on the table and number each length at the top, in the order of installation.
- Lay the lengths on the table, patterns down. To prepare the glue, follow the manufacturer's instructions to obtain the right consistency. Let the glue sit for 10 minutes before using it.
- Using the brush, glue a good half of the strip, from the center to the edges. Insist on the edges. Fold the glued part back on itself without crushing the fold formed.
- Then do the same for the other half of the length, from the center to the edges. Insist on the edges. Fold the glued part back on itself without crushing the fold formed.
- Then do the same for the other half. Allow the length to soak for 5 to 10 minutes.
- Prepare the wallpaper glue, according to the dosages and instructions indicated on the product.
- Spread the glue directly on the wall, using a roller or a glue brush.
- Prepare the wallpaper glue, according to the dosages and instructions for use indicated on the product.
- Spread the glue directly on the wall, using a roller or a glue brush
- Provide a 55 cm wide tub filled with water to soak the length.
- To lay the length, start at the top:
Position it according to the marks, remembering to make it protrude about 5 cm towards the ceiling for the cutout. Smooth with the upholstery brush, working from the inside out to remove the air. Check by taking a step back that the length is well positioned. If necessary, gently peel off and replace. Unfold the entire height respecting the layout. Smooth the entire surface. Remove excess glue with a damp sponge and pass the upholsterer wheel over the edges of the lengths to glue them perfectly. Repeat the operation for all the following lengths.
- To hang the non-woven wallpaper, start from the top of the wall:
Unroll the roll and position the paper, without having cut it (unless it has seams) along the guide line. Make it exceed in height by about 5 cm for the cut. Smooth the wallpaper with the special brush, starting from the inside out to drive out the air. Cut the surpluses at the level of the ceiling and the plinth, using the smoother and the cutter. Repeat the steps for the rest of the surface. Run the upholsterer wheel over the edges of the lengths to prevent them from rising. Gradually remove excess glue with a damp sponge.
