I'll give you a simple and money-saving method, your wall is now very loose, if you can stick the putty when you hang the putty and paste the wallpaper, you spend more than ten yuan to buy a bucket of 107 glue to buy a roller brush, after drying, scrape the putty, scrape the putty with 3 bags and can't use it, almost 50 yuan to buy 3 bags, you can buy a good putty, the putty is dry and sanded flat with sand You can paste the wallpaper, the wallpaper is very good, the main thing is to put the pattern right, it is best for two people to put the pattern right, The corner of the wall or something is pasted on the line.,If you call the wallpaper shop to go to someone, it's definitely going to process money.,He said that if you don't add money, it's a lie.,It must be added to you from the wallpaper.,I said the method you can consider considering.,I've been in this industry for more than 10 years,

Since the landlord doesn't want to be too troublesome, since it is just scraped with nails, I suggest that you brush 1-2 times of interface agent on the wall, and then brush the base film of the wallpaper, and then make wallpaper, how can this also cope with 2 years, if you want to completely improve the living environment, it is recommended to remove the original base layer of the wall, leveling, scraping water-resistant putty, and use good water-resistant putty can not brush the wall paint, or you can paste wallpaper or paint according to your own wishes. Hope it helps.

Okay, help you, you go to the wallpaper shop to look at the variety of wallpaper, **Talk about it, the owner will come to your house to measure the house, that is, the perimeter of the house, generally the top is not pasted, the wallpaper is calculated according to the volume, he will call someone to help, or to help repair the hole, there is no charge to help, and the surface removal of particles is also what he should do Then he (the master) will roll the base film on the wall He (the master) knows that the wallpaper is the price of the wallpaper is included in the wallpaper and the wallpaper Other shopkeepers will help you solve the idea for you and do not spend money You can bargain more I'm a master in this business.

I don't know what you're talking about scraping off the ash with your fingernails. 1. It is normal to drop a little white ash, 2. If it is a piece of shell, it must be shoveled. If it is the first case, you can directly roll the base film and paste the wallpaper after drying.

Stickers are best to find professional people to paste, a room does not cost much, if you paste it yourself, pay attention to the seams of the flowers, it is not good-looking. Start with the shaded corners.

I'm not a professional sticker either, but I just know a little bit about it, and I can add it.

Sandpaper the original wall sandpaper or shovel off (no full shovel is like pockmarks), scrape the putty twice, scrape the putty is to keep the wall flat, no potholes, no cracks. You can paste the wallpaper.

First of all, the humidity of the wall should not be too large. Generally, it is required that the humidity of the wall of latex paint construction should be less than 10% (some paint manufacturers require it to be less than 6%). If the humidity is too high, on the one hand, the moisture in the pores of the wall will block the penetration of the primer and affect the adhesion of the paint film; The continuous evaporation of water will cause the paint film to blister and fall off.

On the other hand, the alkalinity of the new wall is generally large, especially the lime plaster wall, when the moisture in the wall evaporates outward, the alkali of the wall will be brought to the surface, and the concentrated alkali cream after the water evaporates will gather on the surface of the wall, which will cause great damage to the color and luster of the paint film.

Secondly, the alkaline wall should not be too strong. Generally, it is required that the alkaline pH value of the latex paint construction wall should be less than 10. New concrete, cement mortar and lime mortar walls are more alkaline. Pay special attention to lime mortar walls. At present, some areas of Hebei are still using hemp knife lime walls.

There are two stages in the formation of lime walls: the first stage is before plastering, that is, the quicklime is cured into hydrated lime with water, and the reaction is exothermic, volumetric expansion and the process is slow. It takes more than 15 days at room temperature 15.

If the curing time is not enough and the reaction is not complete, the quicklime particles contained in the lime paste will absorb the water vapor in the air, cure and expand, and make the plastered wall burst. Any paint applied to such walls will peel and peel off.

In the second stage, after plastering, the lime plaster undergoes a process of carbonization and hardening with water evaporation, and the reaction is slow because the water in the wall needs to be discharged during carbonization. Under normal circumstances, it takes 9-12 months for lime walls to carbonize to the point where they can be painted (preferably through the whole summer). Prior to this, if the wall was humid, even if the alkali-resistant primer was painted, the satisfactory effect could not be achieved.

Sometimes it can cause alkali, flowering, powder loss and other phenomena.

In short, there are many factors that affect the effect of latex paint, and the most important thing is that the wall should meet the requirements.

This needs to be determined according to the degree of aging of your wall, it is best to check it for a professional to see if you need to re-shovel the wall, you can go to the refresh service of Meitushi.

I didn't brush putty before, but now I can't shovel it at all, directly brush glue, apply latex paint, and so on.

I said, if the original wall was previously used in the case of waterproof putty, it can be treated like this, and in the case of good flatness, you can repair the cracks and polish it comprehensively, and then directly brush the primer, and then brush the topcoat! No substrate treatment is required.

Not so good. Direct brushing will cause chapping afterwards. It is best to shovel before brushing to avoid rework.

Brush glue directly, scrape putty flat, and apply latex paint, very good, you can rest assured.

The wall is best seen clearly to have a say:

1. If there is no putty layer under the paint, you can barely do what the painter says, and you can do it too.

2. If there is a putty layer, my suggestion must be shoveled, and there is no good way to use a grinder to make it faster, but the worker must reject it, because the dust is large, and there is no way.

3. After shoveling, you need to brush 1 interfacial enhancer.

Summary. Dear, I'm glad to answer for you: will peel the skin, the general process is to scrape the putty twice, polish it flat, and then brush the latex paint, the putty wall can not be directly painted with latex paint.

1. Re-brushing latex paint is necessary to remove the original latex paint, not only that, we also need to shovel off all the chalking of the wall, and then clean up the base layer of the wall, re-brush putty powder, and then apply a layer of latex paint. 2. If you don't shovel off the original latex paint, then directly apply the latex paint again, it will bring a lot of trouble to the later stage, because the latex paint is a paint with scattered moisture, if you don't eradicate it, it is likely to affect our later decorative effect and the service life of the wall, which has a great impact on the family environment.

My house used to have putty and paint, from the new renovation, the workers directly on the original basis of a batch of putty, in the brush of latex paint, will not peel the skin?

I used to paint the wall, but now I paint it again, do you want to remove the previous one?

Dear, I'm glad to answer for you: if the original wall is still very flat and there is no bulging phenomenon, you can use sandpaper to polish and flatten it and brush latex paint directly. However, if the latex paint is brushed again, if the color is too light, it will be difficult to cover the bottom, and when brushing, do not put too much water.

[Old wall decoration].

1.First, check whether the wall is hollow, and if there is a local shovel and plastering cement mortar.

In the case of no hollowing, sandpaper sanding, due to the contrast between the old and new colors, you will find that the wall is uneven, apply it with diluted 108 glue as an interface agent, and let it dry.

2.Use construction putty paste or putty powder with water (large white powder mainly prepared with calcium carbonate) to level the potholes and let them dry. 250 sandpaper sanding, sweep the remaining ash, then use putty paste to level, let dry, continue the sandpaper sanding, sweep the remaining ash.

3.Apply latex paint. The primer is added with very little black ink (to a light gray transition color, the purpose is to cover the old paint and putty, to prevent a variety of colors that cannot be covered) once, and then apply the latex topcoat 1 or 2 times after drying.

Materials: 108 glue (or interface agent), putty powder, sandpaper, latex primer, latex topcoat is good. It is sold at local decoration paint shops.

Sand the wall from scratch and paint it directly.

Scraping porcelain is the easiest way to stick wallpaper directly.
