When the old house is renovated and the old wall is renovated, how to deal with the putty and yellow

1.The best way to renovate an old house is to first wipe off the surface decorative layers such as putty powder on the wall, and then expose the original cement mortar base, and then renovate the wall. Decorations such as roller brush interface agent, plastering leveling, putty leveling, latex paint or wall covering.

If you wipe it once when decorating the house, brush the interface agent, and the putty is only hung once, without latex paint or wallpaper, after the old putty layer is brushed with the base film, the putty can be re-hung 1-2 times, provided that the old putty layer is not loose, peeling, falling off, hollowing, cracking and other quality problems. But just dirt.

2.In order to ensure the smoothness and beauty of the putty layer, carefully check whether the wall is firm and firm before construction, and whether the wall has cracks, sanding, and uneven inequality. If you have any of the above problems, please deal with them before scraping putty.

When scraping putty, you need to use special tools, and at the same time, you must master the use of tools and apply evenly to ensure that the putty is full after scraping. After scraping the putty, the edges of the putty around should be put away, and the excess putty should be cleaned up, so that the wall can be smoother and more beautiful. Different walls have different construction requirements for foundation treatment.

3.For example, cast-in-place concrete walls often have some pores and bulges, so the wall should first be repaired and leveled, and the bulges should be smoothed and filled with depressions. If it is a precast concrete wall, there will be some gravel and bulges on the surface, so professional construction workers need to brush the entire wall with a wire brush to remove these debris.

After the wall base is treated, there will still be some depressions in the wall, and the depressions need to be filled with gypsum putty. When formulating, pay attention to the weight ratio of gypsum putty, emulsion and cellulose aqueous solution at 100:5:

Around 60. >4.After adjustment, the gypsum putty is compacted in the depression, and the batch material that has been erected is scraped to ensure that the wall is flat. After scraping putty for the first time, check whether the problem with the previous repair position of the wall still exists.

If there is no problem, after the putty is completely dry, polish the entire wall with fine sandpaper, and then clean the wall. However, if these areas of the wall still have depressions, they need to be repaired and leveled again with putty.

In such a situation, you can choose to repaint it again, or you can choose to paste wallpaper, then you can also choose to paste wallpaper, and then you can also choose to paint it with colored environmentally friendly paint, which can achieve a very good renovation effect.

The yellowed wall skin should be scraped off first, and then repainted, or after scraping off the yellowed wall skin, the wallpaper should be pasted, no matter what the final solution is, the yellowed wall needs to be turned off first.

The old putty should be scraped off, the wall should be renovated, the holes and holes in the wall should be filled, and the better material should be selected and the putty should be scraped several times.

Be sure to eradicate all the problematic examples, renovate the walls, and reapply the glue to avoid yellowing.

When this happens, as long as the wall is strong enough, the interface agent can be used first.

Do the closure treatment, and then scrape the putty normally.

Brush latex paint. You can first roll the glue twice and then scrape the water-based interior wall putty, and then apply the primer twice and then scrape the putty, it should be noted that each step should wait for the previous material to dry before proceeding. In the construction, it is better to use paste putty or plate putty.

Wait for the putty to dry thoroughly and use fine sand.

After sanding, it will turn white, after the wall is treated, first use the primer of the wall paint to brush the wall, remember, you must wait for the primer to dry thoroughly before you can brush the first paint, and then brush the second topcoat after drying.

If the old wall is still yellowed after scraping the putty three times, you can reapply a layer of white cement.

Or it is possible to apply a primer and then paint the interior wall. Whether it is repainting or pasting wallpaper, you don't want to let your hard work go to waste, and at the same time want to achieve a good effect, then the grassroots treatment must be in place, otherwise everything is in vain.

First, the wall has been sanded with sandpaper, then drenched with water, and when it is dry, it is brushed with putty powder.

Then polish and pour water again, dry and then apply latex paint to white, although it is troublesome.

The wall of the old house has not been treated with putty directly, which is obvious, the wall does not shovel off the original old wall skin directly on the new putty, and the dust stain will have yellow on the surface of the partition. In order to be beautiful, as well as to ensure the quality of the wall in the later stage, and to prevent the old bottom from falling off from the new wall, it is recommended to remove the old bottom and then apply putty.

Also, see if there is a product quality problem with the putty and see if the date is expired. Or if you make your own, prepare a white towel; Just put the towel in the mixture to soak it, and then wipe the walls like we do hygiene, and the effect is very good, as white and shiny as just painted.

It may also be caused by the construction being too fast, putty or stucco plaster not completely drying, to prevent it for a period of time, and then re-brush the latex paint when it is completely dry.

In fact, the freshly brushed one turned yellow, maybe the downstairs said that it was dry, and then polished it will turn white! Or maybe the walls of my room are painted yellow.

You can add talcum powder and then do a closure after painting the wall to avoid yellowing.

If the strength of the wall is sufficient, you can do a layer of sealing treatment, and then apply latex paint or scrape a layer of normal putty, so that it will not be yellowed.

It may be because the color of the putty powder is not bought correctly, or it may be because the wall is in disrepair and damp, so this situation will occur, and we must clean the wall before we can scrape the putty again.

You can add some talcum powder to the putty powder and stir it evenly, scrape the putty again, and then polish it again, so as to avoid the yellowing of the old wall scraping putty.

It may be because of the resurgence of moisture, you can add some waterproof materials when scraping putty, so that it will not turn yellow.

Yellowing is a manifestation of the base alkali return, check whether the putty layer has water resistance, will produce the phenomenon of depowdering, the simple operation is to splash a little water on the wall, and then you can.

This is mainly because there is no pre-treatment, and the original wall must be treated once when scraping the wall of the old house to ensure that it does not yellow.

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.

Choose a scraping putty powder that can combine these two colors, scrape it again on the wall, if it is still yellow after scraping, then glue a layer of wallpaper to the wall, which is not only beautiful, but also can cover this defect.

Before scraping putty, you should scrape off all the old wall skin, and then apply new putty, so that the wall will look very white.

When renovating an old house, will scraping putty powder make the wall yellow? The best way to blow putty in the decoration of the old room is to uproot the surface decoration layer such as wall putty powder to expose the original cement mortar base layer, and then re-decorate the wall. Wall roller brush interface agent, plaster leveling, putty scraping, latex paint or wall cloth and other decorations.

If you want to remove it once when decorating the house, and use a roller surface agent, once putty, as long as you do not apply latex paint or wallpaper, you can brush the old putty layer film 1-2 times after removing the putty, provided that the old putty layer has no quality problems, such as osteoporosis, peeling, falling off, hollowing, cracking, etc., just dirt.

<> the new batch of putty in the old house, the main reason for the yellow putty is that the old putty layer is dirty, or the alkalinity is large, containing alkaline substances, and after the putty is blown into the new putty, the alkalinity penetrates into the new putty layer, causing the wall to turn yellow. One way to do this is to separate the alkali, where there are yellowing areas on the original wall, or areas where the weakly alkaline is relatively large and the oxalic acid or other alkali materials are brushed. The other is the uprooted layer of old putty, which seals the wall with an interface agent.

If there is no yellowing, the basement membrane can be rolled to prevent the old putty layer from sealing with the basement membrane. It is recommended to pull out the safest putty on the original wall, so as to fundamentally avoid the yellowing of the putty.

The easiest way is to roll up the old wall with a base film, and in the new putty layer, the putty can choose yellow or white putty powder. Uproot and clean the yellow wall skin or wall, scrape off the gypsum powder putty or plaster, and isolate it. After drying, add a batch of putty, and there will be no yellowing.

If there are a small number of yellow spots or yellow parts of the wall in the batch of putty, and you don't want to, you can use white paint to close the yellow spots or yellow parts. Yellowing is a sign that the alkaline is too large, and oxalic acid can be brushed for neutralization reaction, and then putty can be scraped.
