Not long after the decoration, the wallpaper became moldy, is it because the home is too damp?

It's because the home is too damp, because if the dampness in the home is too heavy, some items are more likely to mold.

I think so, because if the house is damp, it is easy for the wallpaper to become damp and moldy.

It may be because the house has just been built, it has not been put for a long time, and the walls are still very damp.

First of all, sand it clean with sandpaper, and if there is delamination, use a spatula to smooth it.

Then, if the wall is uneven, it needs to be repaired with putty.

Finally, if the wall is flat, it is advisable to apply a sealing primer first, and then a latex paint.

Every year in June and July, the rainy season begins, and there is a proverb that says; "The rain hits the yellow plum head, and there is no sun on the 45th" to describe the plum rain, it can be said that the rain continues to be continuous, and the temperature, high humidity and humidity are the main characteristics of the plum rain. The rainy season makes people feel that the quilt and clothes seem to be able to wring out the water in minutes, not to mention the moldy walls of the home.

In the rainy season, many families will encounter this kind of situation, the degree of mold on the wall is large and small, and the owners and friends usually buy new paint back for repainting, which is not only tired and half dead, but also the cost is not cheap.

1.Once you find a trace of mold on the wall, you should immediately eliminate the mold by using a toothbrush to remove the mold area, and then wipe it with a soft cloth soaked in alcohol, which can effectively prevent the wall from drying out and prevent the growth of bacteria.

2.Buy some lightweight professional waterproof repairs on the market and spray some wall crevices on the wall. If the moldy area of the wall is not serious, you may wish to use 80% alcohol directly to wash the favorite wall, and be sure to keep indoor air circulation afterwards.

Common tips to prevent wall mold.

1.When you open the windows indoors at home, you must pay attention to the air circulation, let the walls blow and dry.

2.Commercially available desiccant can be used to remove moisture from the room.

3.Families with conditions can also buy a dehumidifier, and they can also remove indoor moisture at home.

4.During the decoration, the owner can let the construction master coat the wall with impermeable liquid, so that the wall forms a colorless and transparent waterproof adhesive film layer to prevent foreign moisture from penetrating in, and effectively prevent the wall from being damp and mildew!

There are several triggers for mold in general wallpaper:

1. Water seepage on the wall Most of the wallpaper mold is due to this reason, and its essence is not the mold of the wallpaper but the glutinous rice glue of the wallpaper. This is also the reason why most of the wallpaper mold grows from the bottom of the wallpaper, if it is not treated for a long time and allowed to develop, then the surface will be corroded by mold.

Solution: First deal with the problem of water seepage (water seepage itself is a big problem) to ensure that there is no water seepage, tear off the wallpaper, shovel off the mildew, and repaste. The pursuit of beauty on all repasted, you can just change the moldy place, do not deal with water seepage only use what anti-mildew and antibacterial solvent is.

2. Some wallpaper wallcovering does not have mildew on the surface, but there are mildew marks under the bottom layer, which cannot be touched and wiped off, and there is no peculiar smell. But it's disgusting to watch. Generally, it will not expand again, and this phenomenon occurs rarely.

The problem of light-colored wallpaper wallcovering is mainly due to the fact that the adhesive is contaminated, resulting in the discoloration of the adhesive, and the light-colored wallpaper cannot cover the background color. The source of contamination comes from iron tools that are prone to rust, such as glue mixing containers, power tool rollers, etc.

The solution is still to tear and repaste this is the only way.

3. It is not the phenomenon that appears above, but there are stains on the surface of the wallpaper. If that's the case, congratulations, just wipe it off. At that time, there was no problem when it was posted, but after a year or two, there were black spots, either a lump or a long strip.

Either not on the wallpaper but on the plaster line or in the corner of the wall, the reason is that the sticker is glued too much, spilling onto the surface of the wallpaper and not being wiped clean in time, and the second year or more is wet and mildew.

When wiping, use a clean rag that is not easy to lose hair and not easy to decolorize, wash with water and wring it out, don't wipe it too hard from top to bottom.

4 None of the above phenomena are real paper mold.

We usually divide the wallpaper into 2 situations: mold on the surface of the wallpaper and mold on the glue layer under the wallpaper.

First, the surface of the wallpaper is moldy.

This situation is mostly seen in the dry wall, encountering a sudden continuous hot and humid climate, and the surface of the wallpaper is not cleaned (even some dirt, oil, etc.) will occur on the surface of the mold, and even long hair in severe cases, more white hair and green hair, once the outbreak occurs, the mold area is relatively large, that is, the overall mold, and it is repetitive, and it will grow out again in a few days after wiping it off with a towel.

Solution: This is easier to deal with, although the area is relatively large, it is easy to wipe off mildew with a towel, and the color of the wallpaper has not changed. After wiping off the mildew, spray the surface of the wallpaper with Mrs. Ash anti-mildew agent in time, and evenly spray after ventilation and natural drying can have the effect of killing mildew and mildew.

Second, the glutinous rice glue at the bottom of the wallpaper is moldy.

This situation is mostly seen in a damp wall at home (such as next to the bathroom wall), the wall moisture is relatively large, and the glutinous rice glue at the bottom is originally a highly nutritious material, so when encountering a moisturey environment, coupled with a temperature of about 35 degrees, there will be mold. Mold is generally black, and the form is a black mark that seeps out from the bottom layer of the wallpaper, and the surface of the wallpaper is not very moldy.

Situation description: most of the wallpaper is used in the environmentally friendly material glutinous rice glue, this glue has many advantages, but the only drawback is that the nutrition is too high, easy to breed mold, so when using our decoration department are recommended that the field workers stir the glue when adding ash Mrs. anti-mildew agent, about a small bottle of 100 ml of anti-mildew concentrate can be added to a large barrel of glue, although the amount is very small, but the effect is very good, basically will not be moldy, after five years of testing, Every year, water droplets appear on the surface of the wallpaper during the rainy season, and there are no signs of mold.

Solution: However, the point we are talking about is that once the glue at the bottom of the wallpaper becomes moldy, it can only be torn off and remade into the wallpaper, because the anti-mildew agent water agent cannot be lifted to the glue layer below, and the effect of killing mildew and mildew cannot be achieved. Therefore, it is necessary to pay attention to adding anti-mildew agents when pasting, once moldy, there is no way.

Then remember to add anti-mildew agent when re-pasting, after all, it is not easy to decorate once.
