Pre-installation Inspection: The wall surface must be clean and flat, with no loose or peeling paint.
Use specialized tools for wallpapering or other wall coverings, preferably a professional utility knife.
First, apply a wall primer to the wall surface and prepare the seamless wallpaper adhesive according to the instructions. (Note: Add 2.5 kg of water to 2 kg of adhesive in several batches. Do not add water the first time; stir well. Add 0.5 kg of water for the second batch and stir well. Add 0.5 kg of water for the third batch and stir well. Add the remaining water for the fourth batch and stir well. One bucket of adhesive can cover 25-30 square meters.)
After the primer dries, begin applying the wallpaper adhesive from a corner of the wall. Generally, apply adhesive to one wall at a time (rolling evenly up and down) before applying the wallpaper.
Lay the wallpaper straight down the wall, with the top edge flush with the wall surface. Use an object to align the bottom edge of the entire roll of wallpaper with the top of the baseboard.
Unroll the wallpaper and use a scraper to apply it to the wall, working from the inside out. Align the top and bottom edges before continuing.
If the inside corner is straight, no cutting is needed; continue with the rolling process. If the inside corner is not straight, overlap and cut at the corner.
Two people working together will speed things up. Measure the length from corner to corner, leaving a little leeway. Cut the wallpaper, then have both people stretch it straight and apply it from top to bottom, from the inside out.
Wipe away excess adhesive with a clean, damp towel.
After the entire room is covered, conduct a thorough inspection. Any air bubbles or bulges can be removed with a utility knife.
