Will there be a layer of dust on the white wall that has not been inhabited for ten months?

This is the case with the big white powder painted in many old houses before, and now the latex paint is used, which is much more expensive, why is it still like this?

1) Excessive dilution, resulting in loose paint film, emulsion can not well bond the pigment and filler.

In order to save materials, some workers add too much water, resulting in poor conjunctival effect, and finally it is easy to occur.

2) Do not pay attention to the temperature or humidity during construction.

The temperature is too low, and the latex paint does not dry for a long time; Or the relative humidity is too large, and the latex paint does not dry for a long time, and it is easy to cause powder loss in the end. What should be the correct temperature and humidity?

Generally speaking, the minimum construction temperature of latex paint is 5,0 below the water freezes and no longer volatilizes, latex paint can not dry and form a film, latex paint film formation is a slow process, the temperature is lower than 5 and the relative humidity is higher than 85%, and the water volatilization is extremely slow. It will affect the formation of a continuous paint film of latex paint, and the delivery time should be extended in winter construction, and avoid being exposed to rain in the short term.

By the way, the storage temperature of latex paint.

Latex paint contains a large amount of water, when the temperature is lower than 0, the water will form needle-like ice crystals, which will puncture the broken latex particles and make them break the emulsion and agglomerate.

At the same time, the volume will expand when freezing, which will extrude the latex paint particles, so that the particles will be reshaped and finally break the emulsion and agglomerate.

Therefore, the storage temperature of latex paint should be above zero. Generally, manufacturers will add some additives to reduce the crystallization point in the process of manufacturing latex paint, but they are limited.

Once the latex paint is found to be frozen, it can be placed in an environment higher than 0 and below 40 to be thawed naturally, if there is no obvious abnormality after thawing, it can still be used after stirring, and will not affect the quality. However, if it is cotton-like or granular after freezing, it means that it cannot be used anymore.

Another question below, is the thicker the latex paint, the better?

Many people think that the more viscous the latex paint, the better the quality and the higher the solids content.

In fact, the solids content of latex paint has nothing to do with its viscosity.

Hiding power refers to the ability to cover other colors of the wall when painted on the wall.

The fullness is to say: it refers to the expressiveness of latex paint.

Scrub resistance means: latex paint scrub resistance is the wall after the pollution, can be scrubbed.

A house that I haven't lived in for ten months is likely to have a layer of powder.

Powder, which is an alkaline substance such as calcium hydroxide in cement mortar, is dissolved by water, and then reacts with carbon dioxide or sulfur dioxide in the air, and the product calcium carbonate or calcium sulfate crystallizes and precipitates to form white salt flowers.

Houses that are often inhabited, almost none, and houses that have been idle for a long time, are especially easy to have.

If you don't live in a house for ten months, there will definitely be a layer of dust on the white wall, which can be cleaned up with a feather duster.

It depends on the degree of closure of your house, but also depends on the location of your house, if there is no dust around your house, then there is no dust on the white wall, if the house is easy to produce dust and the closure is not very good, then there will be some dust on the white wall.

Generally speaking, white ash will fall on the wall, mostly for the following reasons.

First, the material is not good.

There are still many brands of putty on the market, and some people think that putty is not important, it doesn't matter what brand it is, as long as it can be used. So will buy some cheap or even small workshop products, how can such materials not have problems after use? When workers paint it on the wall, it often falls off.

Second, the process problem.

Many people are busy with work and have no time to take care of the decoration, so they will contract the decoration to the home improvement company. But not all home improvement companies are responsible, and some home improvement companies only pay attention to quality for the sake of progress. For example, the owner has a six-month renovation contract with the home improvement company, and the workers are lazy when they start working.

When the wall project starts, you feel that it is too late, and apply the putty, but the wall has not yet dried, and immediately start to use the paint, which will also cause the putty to fall off.

3. The dust was not cleaned up.

There is a lot of dust after the putty is on the wall, and the workers must clean up all the dust when dealing with it, and then paint the wall paint. However, some workers are sloppy or the process is not refined, and they will not do the cleaning work after the putty, so that even if the wall paint is painted, the powder will continue to fall off in the later stage.

And if the putty is not done well, it will not only be a problem of powder falling off the wall in the later stage, but also other problems. For example, some people like to stick wall tiles now, and the wall tiles will fall, and the wall tiles will even cause the floor tiles to crack if they fall to the ground. If there are people next to a serious wall, it will even smash and injure people, so it can be seen that no matter how small the work is, it cannot be sloppy.

Yes, because no one has touched this white wall, it will quietly fall with a layer of dust.

If your doors and windows are closed, confined space, there will not be too much dust, but it is clean, there is no one living in ten months, if you move in to live, you still need to clean it!

Don't say that there will be dust on the white walls where no one lives, and there will be dust on the white walls where people live.

Even if it is a house where people live, there will be dust on the walls, and there will be dust if no one lives in it.

There will definitely be dust, anywhere, as long as you don't clean it, there will be dust, and I'm really helping you look forward to it

This should be possible, the house is not well sealed, there should be dust.

I won't be able to live for a month.

Summary. Hello, I can't live in the whitewashed wall after half a month.

Hello, I can't live in the whitewashed wall after half a month.

It is recommended to ventilate for a longer time to prevent harmful substances from endangering health. Newly renovated houses do not rely solely on time as the standard for occupancy, but also need to be tested by professional institutions, and the content of toxic substances in the room has reached the standard of occupancy before moving in. Moreover, in the case of ventilation, if the formaldehyde removal method is used well, it can also be shortened to shorten the check-in time; You can raise some plants in the room, such as inverted spider plant, tiger tail orchid, a taste orchid, monstera bamboo, aloe vera and other hot day scavengers, studies have shown that tiger tail and spider plant can absorb more than 80% of the harmful gases in the room, and the ability to absorb toxic substances is extraordinary.

The concentration of formaldehyde in indoor air is related to the following four factors: indoor temperature, indoor relative humidity, indoor material loading degree (i.e., the surface area of formaldehyde emitting materials per cubic meter of indoor space), and indoor air circulation. Under the conditions of high temperature, high humidity, negative pressure and high load, the intensity of formaldehyde emission will be aggravated.

Under normal circumstances, the release of formaldehyde can not collapse for up to 3 to 15 years. Formaldehyde in indoor air has become the main pollutant affecting human health, especially in winter, formaldehyde in the air is the most harmful to the human body.

No. It is recommended to ventilate for a longer time to prevent harmful substances from endangering health.

It is best not to move in immediately, the indoor air pollution level is the heaviest after the renovation, and you must open the window for ventilation for two or three months before considering whether you can move in.

No, it is recommended to ventilate for a longer period of time to prevent harmful substances from endangering your health.

Yes. Ordinary windows will have air flow.

The air is not clean.

Over time, dust in the air will settle in the house.

There will be a layer of dust.

It depends.

If the quality of the house is relatively good and the windows and doors are well sealed, there will generally be no such situation, but it depends on the specific situation.

If you haven't lived in it for 10 months, if your doors and windows are closed, there will be dust in the house, but it's not serious? If your windows are open, there will be a lot of dust inside due to the wind! However, although the former room is a little cleaner, it will be more humid.

The latter will be drier indoors!
