One、How to apply wallpaper at corners
1、Address basement settlement cracks
Step 1: Measure from the center of the last wallpaper panel towards the concave corner, adding 2.5cm, and then cut a section of wallpaper to this width.
Step 2: Apply the wall covering, aligning and connecting the last piece, and ensuring it is flush with the corner of the wall.
Step 3: Use a scraper to apply the putty powder upwards and downwards, ensuring that the protruding portion adheres to the wall. Also, wipe off any excess adhesive from the scraper.
Step 4: Measure the width of this section from the self-leveling angle outwards and add 5mm, marking the wall accordingly.
Step 5: Place a level on the pencil markings to check for verticality, and apply adhesive to the wall covering.
Step six: Align the outer side of the wall covering with the vertical line, and then use this line as a guide to apply the remaining wall covering to the room.
2、Methods for addressing subsidence and unevenness in buildings
Step 1: Measure from the center of the last wallpaper panel towards the concave corner, adding 2.5cm, and then cut a section of wallpaper to this width.

Two. important considerations for installing wall coverings at corners.
1、Wall construction for wallpaper application:The walls can be prepared with a cement and lime mortar base, which ensures a smooth surface. After drying, apply a layer of putty powder and smooth it with sandpaper, then use 107 adhesive or other adhesive to attach the wallpaper.
2、Process for wall covering:Clean the substrate, fill gaps → Apply joint tape at the seams of the gypsum board, apply putty, sand → Apply putty, smooth → Apply anti-moisture agent → Apply primer → Apply wallpaper → Soak wallpaper and substrate with adhesive → Apply adhesive to wallpaper → Paste, trim, apply, and match → Remove air bubbles from adhesive → Wipe off adhesive → Finishing.
3、Wall covering installation key points:When preparing the substrate, it must be clean, level, smooth, and the moisture-resistant coating should be applied evenly and not too thickly. To prevent wallpaper and fabric from detaching due to moisture, we can apply a moisture-resistant coating. Draw vertical and horizontal lines to ensure that the wallpaper and fabric are level and the pattern is correct. Plastic wallpaper expands when wet or exposed to glue, so it is recommended to use moisture-resistant wallpaper, such as fiberglass-based wallpaper and fabric. If the wallpaper does not expand or shrink when wet, no pre-wetting is required. After pasting, immediately apply pressure to the wallpaper adhesive to prevent bubbles. Wipe away any excess adhesive immediately.
