1, moldy - generally there will be spots (mold black spots), should first check whether the wall seepage, and whether the glue is not completely dry during construction, there is a wind out of the wind or indoor and outdoor temperature difference, it is easy to cause wallpaper Such as the curling of the drum and the future due to the long-term existence of moisture and air in the wallpaper, and mildew. The environment humidity during the rainy season is also easy to make the wallpaper moldy.
Therefore, the room after the wallpaper has just been paved should be closed, and dried. After 3 days of wallpapering, you should use a damp towel to gently wipe off the wallpaper glue remaining in the seams of the wallpaper. At this point, the entire room can be completely ventilated. Also remember to try not to let the wallpaper soak in the water before the wallpaper paste, otherwise it is easy to make the wallpaper moldy!
If the mold is not too big, it is recommended to wipe it with soapy water or detergent. If it is not, wipe it with a cloth dampened with alcohol. If it is not too serious, remove the mold by rubbing it two or three times. Another method of removing mold is to use bleach. However, it is easy to irritate the skin, so be sure to wear rubber gloves when using it, and use water to clear it. Some people may worry that bleach does not dare to use it, fearing that the original color will be removed. Then use some special mold remover to deal with wall mold spots. You can ask in the shop where you buy wallpaper.
2, wallpaper edged - wallpaper edge after construction, should check whether the brush is uniform and the wall water absorption, appropriate increase the bonding strength of the glue.
The reason for the wallpaper curling is that the wallpaper quality is not good, but also because the wallpaper is not smooth, it is caused by the flattening. In addition, it is mainly due to improper handling of the wall foundation or mistakes in the paste. Therefore, when affixing the wallpaper, it is necessary to ensure that the basic treatment is clean and the adhesive with good viscosity is selected. The wallpaper of different materials should be matched with the adhesive.
3, bubble - check the amount of glue applied or the wall is glued, you can fill the bubble, the wallpaper is tight.
The main reason for the appearance of bubbles in the wallpaper is that the glue is not evenly applied, and the bubbles are not ejected when the paste is used. In order to prevent the glue from leaking during construction, it can be scraped again with a scraper after brushing to ensure uniform brushing. If bubbles are found during construction, the wallpaper can be cut with a knife. After the air is released, the glue is evenly scraped. The air can also be extracted by a syringe, and the glue is poured and flattened to ensure that the wallpaper is flat.
4, color difference - wallpaper color difference occurs during construction, should first check whether the wallpaper model and batch number are consistent; then the final construction of the paper flattened to see if there is color difference (flower, same direction), if there is color difference should stop construction. If the color of the wallpaper is different after construction, it should be the contrast of light or moisture.
5, not on the flower - wallpaper misplaced during construction, should check whether the construction method is correct or whether the wallpaper is not flowered before construction, or check whether the paper is stretched or wrong position. You can take the last brushing sample on the workbench.
