Wallcovering technique refers to the process of installing wallpaper or other decorative coverings on a wall. This can involve applying adhesive, cutting the wallcovering to size, and smoothing out any bubbles or wrinkles. The technique used will depend on the type of wallcovering being installed, as well as the surface of the wall.

Here are some common wallcovering techniques:

1. Paste-the-wall technique: This technique involves applying adhesive directly to the wall, rather than to the back of the wallpaper. This method is quicker and easier than traditional wallpaper hanging, but is only suitable for certain types of wallpaper.
2. Pre-pasted technique: This technique involves applying water to the back of pre-pasted wallpaper to activate the adhesive. This method is quick and easy, but the quality of the adhesive can be variable.
3. Traditional wallpaper hanging: This technique involves applying adhesive to the back of the wallpaper and then hanging it on the wall. This method is more time-consuming but allows for greater control over the position and alignment of the wallpaper.
4. Murals and large-scale graphics: For large-scale graphics and murals, a special technique may be required. This may involve multiple panels of wallpaper that need to be carefully joined together, or a self-adhesive vinyl material that is applied directly to the wall.

Regardless of the technique used, it’s important to take the necessary precautions when working with wallcoverings, such as wearing gloves, protecting floors and furniture, and following the manufacturer’s instructions. Additionally, it’s always a good idea to have an extra roll of wallpaper or a few extra panels on hand in case of mistakes or damage during installation.
