For the correct and even placement of wallpaper on the ceiling, marking the strips should. Each strip is equal to the width of the roll of your wallpaper minus a pair of centimeters. Marking is carried out around the entire perimeter of the ceiling and will allow it quite easily and most importantly smoothly glue the wallpaper. Do not forget to turn off the electricity and close the windows and doors to eliminate draft. Now you need to prepare glue for wallpaper. For different types of wallpaper, manufacturers recommend using their type of glue. For vinyl wallpaper — one type of glue, for paper — the other. If you have liquid glue, it is recommended to dilute it with water 40 minutes before the start. Be careful and do not overdo it, since the glue is better for pasting the ceiling with a more viscous and thick consistency. It is recommended to strictly adhere to the manufacturer’s instructions!
