When renovating an old house, do you have to use glue to scrape putty?

When decorating the house, putty powder.

Cement and sand are the most basic decoration materials, which are indispensable in every family, so before we buy fashion and other things, we must first buy these most basic things, so we need to understand it, scrape putty.

Do you have to put glue, you must do a good job of supervising in this regard, in addition, what are the precautions for choosing putty powder.

Do you have to put glue in the putty.

The design concept of putty powder.

No glue is added. Environmental protection is the first thing, there is no doubt about this. The finished putty powder can be mixed directly with water. The ratio of ash to water is mainly based on experience, as appropriate. For those with special needs, 801 glue can be added appropriately. Kraft paper bandages use white latex.

Basically 48 hours to dry. Judged by feel. The second putty must wait for the first time to dry and then rough sanding, and whether the first putty is dry or not should also be judged by the naked eye and feel.

When stirring putty powder, the principle of water first and then powder should be followed, and gradually added. The bucket is filled with one-third of the water, and then about one-third of the putty powder is poured into the bag. Stir well with an airplane drill.

Batch putty is one of the more important processes in the wall treatment stage. The putty used for batch walls can be adjusted by yourself, or you can buy ready-made putty powder. In fact, experienced workers still like to prepare themselves or use semi-finished putty powder to come back to make it, because the putty they make is firmer and more delicate.

Precautions for choosing putty powder.

1. Greedy for small and cheap and suffer big losses.

This is a matter of consciousness, don't feel that putty powder only plays a role in leveling, just choose a cheaper one, this is the basic layer of the wall, if you don't lay a good foundation, the loss is huge.

2. Identify the name tags that are indiscriminate.

A lot of putty powder on the market is on the famous brand, such as: Nippon.

Special putty powder, Dulux.

Special putty powder, Carberry.

Special putty powder, etc., are sold in the market with these brand-name packaging bags filled with inferior putty powder, and even some brand-name stores are also selling their first-class brand of inferior putty powder, which seriously damages the interests of consumers.

Under normal circumstances, most of these brand-name paint factories do not produce putty powder, you can broadcast the service of the head office ** to check whether to produce putty powder, what packaging, whether there is anti-counterfeiting, etc.

3 Environmental performance is preferred.

The raw materials used in cheap and inferior putty are extremely not environmentally friendly, and the formula is an old formula that does not meet the national standard, and has been banned by the state many years ago.

Formaldehyde pollution as we all know.

Formaldehyde-containing building materials that exceed the standard or even seriously exceed the standard are immeasurable in their damage to the human body.

This article clearly tells you that you must put glue on the putty, from which we have already known that the design principle of putty powder is not glued, so we must do a good job of supervising the work when carrying out this project, if they add glue they must stop them, otherwise the glue will affect the effect in the later stage, and secondly, I also understand what the precautions for choosing putty powder are.

Now there is a special putty powder, which does not need to be glued. Putty powder is a kind of surface leveling powder material that pretreats the construction surface before paint construction, the main purpose is to fill the pores of the construction surface and correct the curve deviation of the construction surface, so as to lay a good foundation for obtaining a uniform and smooth paint surface.

The renovation of the old house, the use of putty powder can be without glue, just add water, it should be noted that the renovation of the old house, must deal with the base, it is recommended to scrape the putty before the interface or wall solid!

No, you don't. Now there is glue in the putty powder, no need to mix with glue, the current putty powder hangs up, as long as it is not damp for a long time, it will not fall off.

The use of *** putty can be done without glue.

The use of glue when scraping putty can do several things:

1.Strengthens adhesion. In order to protect the surface of the wall, a layer of primer may be applied when painting, so that the primer needs to be sanded to a smooth surface before scraping the putty, otherwise the putty will not stick firmly.

Therefore, open your eyes and apply a layer of glue before scraping the putty, which can increase the adhesion between the putty and the wall, so that the scraped putty is not easy to fall off.

2.Adjust the water absorption of the wall. If the water absorption of the wall is too strong, the putty scraped out is absorbed too quickly and causes uneven drying; If the water absorption of the wall is too poor, the putty scraped out will accumulate on the surface of the wall, and it is not easy to polish and flat.

After applying the appropriate amount of glue, the difference in water absorption of the wall can be repaired, and a smooth putty must be effectively scraped.

3.Reduces cracking. Due to the influence of environmental factors such as temperature, the wall surface after scraping putty is prone to dry cracking, and applying glue can reduce the occurrence of this situation and increase the stability of the wall.

Therefore, the use of glue when scraping putty can improve the effect and quality of scraping putty, making the wall more flat, firm and beautiful.

There are several main reasons to use glue when repairing wall scraping putty:

1. Improve the adhesion of putty: Glue can increase the adhesion of scraping putty, making it more firmly adhered to the wall, avoiding the problem of falling off or cracking after scraping putty.

2 Fill in wall cracks: If there are cracks in the wall while repairing, using glue can fill these cracks at the same time as the putty is filled, preventing the cracks from reappearing.

3. Enhance the water resistance of the missing burial sale: The use of voltaic glue can improve the water resistance of the putty and avoid the putty falling or cracking in a humid environment.

4. Strengthen the details processing: The use of glue can also be more refined in the details, such as the corners and grooves of the wall, so that the repaired wall surface is more flat and beautiful.

It should be noted that the quality and amount of glue should be paid attention to when using glue to avoid adverse effects on the repair effect liquid family. In addition, different types of putty need to use the corresponding glue, and the suitable material should be selected according to the actual situation.

When the old house is renovated, will the putty powder turn yellow? Can I paint latex paint?

With the development of society, the house sales market in many cities has also entered the era of stock, which means that more and more people will have to face the problem of renovating old houses. The old house is aging, the exterior wall is leaking, and the house equipment is damaged. This series of house problems is also a problem for many people.

The wall problem is the most common thing encountered when renovating, many people will see that the putty wall begins to turn yellow just after scraping the old house, and then we will talk about this.

Reason 1: Alkali return occurs at the base level.

If there is a situation of alkali return to the base layer, it is necessary to use the interface agent to do a closed solution first, and then use the normal process to scrape putty and brush the latex paint.

Reason 2: Putty powder composition problem.

The yellowing of the wall is also related to the new and old layers of the wall and the calcium content in the putty powder. The wall is old, and at the same time, a lot of PVA glue is used, so that the unsaturated fatty acids formed by the dissolution of the glue will be converted into pale yellow calcium by chemical reaction with sodium ions. In such a situation, it is necessary to first roll the glue on the wall twice, then scrape the water-soluble interior wall putty powder, and finally apply the topcoat several times and then scrape the putty.

Reason 3: The base is not cleaned and tidy.

The wall still appears yellow after scraping the putty three times, and there is a lot of possibility that the base layer is not cleaned and tidy. In this case, it is necessary to rub a layer of cement on the wall again, or give the interior wall a top coat and then apply a top paint. To keep in mind that for the renovation of old houses, only the water-resistant putty powder on the wall needs to be more than 5 years, and the next renovation needs to be cleaned and tidy, otherwise the application will be affected afterwards.

When natural ventilation is blocked, the walls continue to turn yellow and black again due to chemical changes in the raw materials.

Whether it is repainting latex paint or laying wallpaper, if you want to achieve a good effect, and you don't want your hard work to be in vain, then remember to pay attention to the grassroots solution, it is better to spend some ideas in the early stage than waste later.

Scraping putty powder will not turn yellow, scraping out is still very white, and the same as a new house, you can brush latex paint, which will also make the house very new, scraping putty and brushing latex paint can be.

Now it is possible to turn yellow in such a situation, and I think it is possible to paint latex paint.

Yes, so be sure to remove all the previous putty powder, and then you should also choose a more cost-effective, do a good job of ventilation, and then you can also choose to brush latex paint.

RenovationThe so-called complete renovation of the wall of the second-hand house means that we remove all the decorative layers of the original wall. This involves removing the latex paint from the wall, removing the putty layer from the wall, and exposing the plastering layer inside. Second-hand houses because the original rubber has been inhabited, so there are more or less paint or stains on some parts of the wall.

If most of the whole thing is dirty, it is recommended to renovate it all!

It's not easy to shovel, so don't embarrass the workers, even if they are capable, the labor cost is not the same. At this time, the best thing to do is to shovel some dirty areas on the wall and smooth them with putty. Apply latex paint directly or paste wallpaper.

The quality of the putty on the original wall will generally be poor, and it is easy to crack, peel, and pulverize in the later stage of direct brushing latex paint, so it is recommended to use gypsum leveling after all the eradication, and then scrape the putty and then roll the latex paint, which is more reliable. If the damaged pit is too deep, it is recommended to repair it with gypsum powder and then repair it with putty powder; Now many owners generally have two ways to deal with this wall, one is directly pasted with wallpaper, one is directly painted, with good coverage of latex paint is still possible, excessive, if the decoration to the age, the conditions are still allowed, then redesign and decorate.

In fact, the wall is to polish the layer of latex paint on the surface of the paint, so as to prevent the new and old materials from falling off without fusion. For how to remove putty powder from old walls, there are actually many methods, including the use of wall planers, angle grinders, etc., but the dust with the machine is indeed too big, and ordinary people can't stand it. And the simplest is to wet and blister with water, and it is easy to shovel.

To get the worst things, we still have to shovel off, and after shoveling off, we also need to roll the wall solid, not to mention the waste of construction progress, not to mention the cost of an extra cost. If you feel that the wall is dirty, you can brush all the wall solid, and brush the latex paint with putty twice after scraping, as long as the wall is fine, the putty will not fall.

You can't paint directly on the old putty powder, because the old putty powder has been around for a long time, and its surface is also very unsmooth.

It is not allowed to paint directly on the old putty, as this will make the wall look very thick and not have a very flat effect.

Of course not, if you do this, it will only make the wall crack or peeling phenomenon in the later stage, so we must remove all the old putty powder before painting.

Putty powder is the basic project of wall decoration, it is related to the later painting of oil teasing paint or tile paste engineering, so the basic work of brushing putty powder must be in place, the putty powder must be smooth and flat first, and some houses need to be redecorated generally choose to re-paint the wall, then it is necessary to be extra careful, the following will introduce to you the original putty of the redecoration wall needs to be eradicated, and it is better to scrape the putty powder on the redecoration wall a few times.

2. The second scraping putty is mainly for leveling and priming, and at the same time, the secondary scraping putty can also cover some defects of the original wall. The second time the putty is scraped mainly for repair, and we can check if there are some parts of the wall for unevenness. Of course, putty is also scraped three times, depending on the specific situation of the walls of the room.
