Is it a new wall or an old wall? Just after the putty is yellowed? That's probably because your putty powder is useless, right, you generally need talcum powder.

Putty powder cellulose.

This is how the glue comes out.

It shouldn't be like you said.

Or you ps2 up.

Let's analyze it. This situation is generally seen in the renovation of old houses. Regardless of whether it changes color or not, first scrape the first putty flat, then brush it all over with a wall sealant (or varnish), and then scrape the putty a second time after it is dry to ensure that it does not have any more macula.

Haha, a unique stunt, it's easy not to pass it on!!

Reasons: 1. It may be caused by other objects attached to the wall, the old wall is alkaline, the new wall plastering base contains a lot of impurities, wood chips, cinders, etc., and the wall smoked by oil will also cause yellowing.

2. The wall coating has quality problems or is caused by improper construction (rollers have problems.

putty is dirty, etc.), so that impurities are mixed in the paint.

Solution: 1. Don't eradicate, paint some hand-painted with environmentally friendly monochrome latex paint, you can use 2-3 kinds of colored latex paint to match. If the original wall is relatively firm, you can also buy latex paint to brush twice, which can also achieve the effect of treatment.

2. Shovel off the original old melamine to the base layer of the wall, and then carry out plastering, plaster leveling, and scraping the repair of melamine. If the area is large, it is recommended to eradicate them all. If the wall contains more impurities, it is necessary to increase the number of scraping times of the melamine coating, that is, 2 more scrapes.

The solution to the yellowing of the old wall after scraping putty is: use neutral putty or glue to adjust talcum powder (do not add white cement) and then batch two batches, close and polish and paint. As long as the strength of the wall is enough, a layer of sealing treatment can be done with an interface agent, and a layer of putty or latex paint can be scraped on the surface normally.

According to the correct treatment method, first of all, please check whether the putty layer has water resistance, whether there will be a phenomenon of depowdering, the simple operation is to splash a little water on the wall, and rub it lightly with your hands without obvious powder.

If there is a serious powder loss, please remove all of them and remove them to the surface layer of cement mortar, and then they need to be treated with interface agent. The wall is sandpapered, watered with water, brushed with putty powder, and then sanded and watered, and then painted with latex paint when it is dry.

How to deal with the yellowing of putty after scraping?

It is necessary to mix with water-blended talcum powder and neutral particles, and then polish and paint. Moreover, if the strength of the wall is sufficient, it should be closed with an interface agent. Under normal circumstances, you can scrape a layer of putty and then apply latex paint.

Or take a look at the water resistance of the putty, splash a little water on the wall and rub it with your hands to see if there is any powder. If there is a serious powder loss, the wall should be cleaned and removed to the cement mortar bridge and this layer, and then the interface agent treatment should be carried out. And use sandpaper to polish the wall, then drizzle it with water and then brush it with putty powder, and finally drench it with water after the polishing is completed, and after it dries out, as long as the latex paint is applied, it will be white.

What are the precautions when scraping putty?

1. Before scraping putty on the interior wall, you should use a ruler to measure the wall to see if the wall is flat. If there is an uneven place, it should be solved by grouting repair. Then use a primer to close the wall, which will prevent the putty from absorbing too much.

2. Then when scraping putty, the thickness of its first pass should be within 5 mm, and then the wall should be leveled. Then when scraping the putty for the first time, it is necessary to grasp the strength and scrape evenly, so that the whole wall can be relatively full. After scraping the putty, wait for the wall to dry before proceeding with the construction.

The drying time will be about 24 hours, depending on the weather conditions and the quality of the wall.

3. After the putty is scraped, the wall should be polished, so that the wall will be more uniform and delicate. When polishing the putty, it is best to carry out the construction at night, because the wall is under the illumination of the light, and its flatness can be seen more clearly.
