Problem - Stain emergence

Stain

All the wallpaper manufactured by our company, within the framework of the quality guarantee of the Ral-GZ479, refers to all the production tested, which results in the highest quality requirements. Thanks to this, we can provide high quality production quality that does not pose a health risk.

The emergence of stains may be associated with a blocked or improper surface, and its characteristic problems - moisture suction capacity.

Possible moisture residues on the wall can begin to form a chemical reaction with the surface, and the wallpaper itself may not be the cause of the defect. Similarly, mold may form on the wrong wall. For this reason, it is always necessary to check exactly whether the treated wall implements all the preconditions for gluing the wallpaper.

More information on surface preparation is available here.

In some cases, a defective product, despite another control and test sticker, is on sale.

In this case, it is about the spots produced as a result of mechanical treatment. These spots are visible immediately. In this case, no gluing is required.

 

The appearance of spots after a long time

If the spots on the wallpaper do not appear until complete drying, the product itself is not the reason why the stains occur in the future. The reason for the appearance of spots should be sought elsewhere.
