When the wallpaper is constructed, the flowers are misaligned. Check whether the construction method is correct or whether the flowers are not aligned before the wallpaper construction, or whether the paper is stretched or the position is correct. It can be assembled on the workbench without glue. The shifting of the cutting edge of the wallpaper will also make the pattern of the previous roll of wallpaper and the next roll of wallpaper incomplete, and affect the decorative effect of the wallpaper.

That is, the color difference is found when the wallpaper is posted during construction. Please change the wallpaper.

Check whether the wall and the construction tabletop are too dirty, and remove the excess glue.

If the wallpaper falls off after construction, you should check whether the wall surface is handled well or whether the glue meets the requirements.

The edge of the wallpaper is raised after construction. Check whether the glue is evenly applied and the wall is water-absorbent, and the adhesive strength of the glue should be appropriately increased.

The wallpaper shrinks and cracks after construction. Check whether the construction method is incorrect or the adhesive strength of the glue is poor. When the sealing paint on the bottom of the wall is not fully dried, the construction will shrink.

After the wallpaper is constructed, the background color or shadow is exposed, and you should check whether the wall color is consistent or whether the glue is accumulated.

The edges are subjected to excessive pressure and friction during construction, so the friction to the wallpaper should be reduced, and the glue on the edge of the wall should be checked for removal.

If the paint sticks to the wallpaper, it should be wiped off with a dry cloth immediately. Do not expand the traces. Quickly wash it with ethanol or ethylene peroxide, and then rinse with water.

Check the amount of glue or whether the wall has been glued. You can pour water into the air bubbles to close the wallpaper tightly.

There are ink and pen marks on the wallpaper, which can be cleaned with ethanol.

Wipe it off and wash it off with water.

Paint on the wallpaper can be cleaned with turpentine or kerosene.

Scrape off the chewing gum grease on the wallpaper as much as possible, or wipe it off with paraffin (rub with ice cubes, the chewing gum will fall off more easily), and then rinse with water.
