What could be nicer than completing the final stage of the repair work - wallpapering. And what a disappointment can come at the sight of spilling yellow spots on the wallpaper. Why they appear and how to deal with them, we consider in more detail.
Causes of yellow spots on the wallpaper
The protruding yellow spots on the freshly pasted wallpaper can appear for several reasons:
- Badly shot old wallpapers can be printed through a new layer;
- Again, the old wallpaper glue under the unreleased wallpaper;
- Poor quality wallpaper glue, although this is rare today;
- The metal fasteners remaining under the wallpaper rust from the abundance of glue and all the consequences of this, come out;
- Poorly prepared base, or rather poor putty or primer;
Grease of any origin on the adhesive layer or wallpaper. Also, some rubbish caught between the base and a new layer of wallpaper can become the cause of yellowness.
Elimination of yellow spots on the wallpaper
If the reasons for the yellowness on the newly glued wallpaper lie in a poorly prepared base and poor-quality putty, then the removal of a new finish layer cannot be avoided. It’s worth taking off not only the wallpaper, but also filling the walls again. Yes, laborious and expensive. Therefore, even at the preparatory stages, it is not worth saving on materials and time neglecting the cleaning of the base and its leveling.
If yellow spots appeared after contact with fatty substances, then you can remove them using several methods:
- If the wallpaper is fabric or paper, then attach a dry cloth to their surface and go with an iron. Effectively not in all cases;
- You can try the composition based on gasoline. To prepare it, you need to take 1 part of starch and 0.5 part of gasoline. Mix everything and apply for a while on greasy spots. Before cleaning the stain, it is necessary that the gasoline disappears;
- Non-woven, vinyl wallpaper and silk screen printing are much easier to clean. Usually simple cleaners and a sponge help with this. Only when erasing yellow spots do not overdo it and do not erase the top layer of wallpaper.
If black spots appeared on the newly glued wallpaper, then simple methods will not get rid of them. Since the main reason for their appearance, except for the rough base, this is the appearance of the fungus. There is no way to remove the wallpaper, leveling layer and treating the wall with an antiseptic.
