If the putty is scraped well, the wall will be very flat and smooth. Let's take a look at the skills and related information of putty scraping.

Is there any skill in scraping putty? 1 first, the skill of scraping putty quickly and smoothly.

1 First of all, it is very important and a prerequisite to ensure that the material of putty powder is good, and the choice of putty powder should be different whether scraping the inner wall or the outer wall.

2. First put water in the bucket, then pour in a proper amount of putty powder and stir with an electric drill. It is required to mix evenly and use it up within the specified time. Generally speaking, it is enough to stir until it is paste.

3. Before blowing putty, the wall must be cleaned, and the bottom cleaning is very important, otherwise the problem of non-stick will appear in the later blowing putty.

4. In the process of putty scraping, first scrape the upper part of the wall, and then scrape the lower part of the wall. When scraping, you must master the essentials of hand movements, the wrist should be forced evenly, and then the scraper should be tilted, so that all the excess putty can be scraped off. When scraping the wall, try to scrape the left and right sides, not up and down.

Generally speaking, putty should be scraped three times, and then each time it has to be dried before it can be operated.

Second, the specific matters needing attention when blowing putty

1 and 1 The point of attention is to consider the roller brush, which can also determine whether the putty is scraped well. Roller brush must be good, its wool quality and wool quantity must be moderate, otherwise it will affect the painting effect.

2. The second thing to note is that the putty can't be blown directly by the cold wind in winter, otherwise the wall will be easily blown dry and will crack later.

3. The third attention is to control the thickness of putty, which is generally about 2mm, and should not exceed this size requirement.

How to scrape putty? First of all, we need to buy good quality putty, and we need to know the ratio of putty to water, and then mix it according to the ratio, and then mix it evenly. Be sure to clean up the wall foundation before scraping putty. If there are missing corners or cracks, repair them with gypsum powder first, and then treat them with kraft paper or cloth.

2. After the base is treated, you can start scraping putty. Generally putty should be scraped three times. And every time you scrape it, wait for the putty to dry thoroughly before proceeding to the next operation. The thickness of the putty is 2 mm If you scrape the putty in cold weather, you must remember to protect the wall after scraping the putty. When the putty is not dry, close the window to prevent the putty from cracking due to dry wind. Finally, the lighting should be polished, and the angle of yin and yang should be horizontal and vertical. When scraping putty, there are sundries or sand grains that should be handled in time.

What are the skills of scraping putty?

1, the place where putty is scraped shall be treated, the dust shall be cleaned, the prominent place shall be removed, and the sunken place shall be leveled with mortar. The flatness and verticality of the angle of Yin and Yang should meet the requirements, and the bottom ash surface should be leveled with wood.

2. Before putty is scraped, if the concrete wall is seriously polluted by oil, it needs to be cleaned with washing powder water or 10% alkaline water, and then with clean water. If it is ordinary oil, it can be sanded. When the concrete and mortar walls are 70% dry, they can be directly constructed. If it is dry, water it.

3. If the wall absorbs water quickly, it should be sprayed with 1: 2 or 1: 3 107 glue solution to avoid powdering of gypsum powder due to excessive water loss.

4. If the wall is mixed mortar, lime mortar and cement mortar, it is necessary to wait until the bottom ash is 70% dry, and then cover the surface. Plastering treatment, should be applied vertically, and then calendering leveling, twice the thickness of 2 mm.. Plasterboard wall or concrete wall can be operated by plastering scraping method, which should be scraped twice, and its thickness is roughly 0,5 ~1mm.

Is there any skill in scraping putty? First, how to scrape the wall putty.

1 Clean the putty wall first. If there is an empty drum, repair the empty drum first, and then remove the residual dust and mortar on the wall.

2, blow be bored with child should pay attention to the Angle of Yin and Yang of metope, the Angle of Yin and Yang must be straight. During construction, the internal angle and Yang Can are extruded with aluminum alloy bars, and the internal angle and external angle are operated with special tools.

3. The first putty construction, its thickness should be between 4 mm and 5 mm, blow be bored with child is to level the wall, construction can't wipe back and forth, be sure to brush clean.

4. How to blow putty on the wall? When scraping the putty for the second time, wait until the putty is dry for the first time, and the thickness should be kept within 3 mm ~ 4 mm. At the same time, wait until the putty is basically dry, and then polish the surface with a scraper to ensure its lines and colors are in the best condition.

Second, what are the skills for scraping putty?

1, when cleaning the wall, clean the dust between the ceiling and the wall, and level the concave and convex parts to keep the flatness of the wall. If there are stains on the wall, you can clean it with laundry and then dry it with water.

2. When mortar construction is carried out on the wall, putty construction can only be carried out after being 70% dry. If it dries for too long, you can pour some water on its surface.

3. For the wall with high water absorption, it is best to apply 1:2 glue at one time to prevent the gypsum powder on the wall from losing water and powdering too quickly. If it is a plasterboard wall, wipe it with a wet rag first.

4. When the putty powder is dry, sand the wall surface with sandpaper, and then clean the floating ash on the wall surface with a wet rag, so that the wall surface can be further decorated, such as wallpaper and stickers.

Is there any skill in scraping putty? 3 What are the tools for scraping putty?

1, three musketeers blows putty.

Scraper, trowel and spirit level are commonly used putty scraping tools. There are three kinds of scraper, namely flat scraper, triangular scraper and crescent scraper. The quality of scraper is closely related to the construction quality and efficiency. The trowel, also known as trowel, mainly plays the role of smoothing and filling, and consists of a knife body and a handle. The cutter body is divided into two types: tooth shape and plane shape. The leveling ruler is mainly used for leveling, and it is recommended to choose aluminum alloy material.

2, putty mixer

It is too difficult to mix putty by hand, so people invented putty mixer. This machine is mainly used for mixing putty powder. Its advantages are time-saving and labor-saving, and it is more uniform than manual stirring. But some particles will inevitably be produced, so how to solve the particles? You can grind the particles twice with a putty grinder.

3, putty spraying machine

The traditional construction mode is that the master paints directly with a brush, which is too inefficient and time-consuming. Choosing putty spraying machine can save our time and energy and greatly reduce the construction time. Its function is to spray putty directly on the wall and then level it manually.

4. Putty grinder

After the putty is thoroughly dried, it needs to be polished again to make the wall more flat. The traditional way is hand grinding, which is very time-consuming and produces a lot of dust. However, new grinders generally have their own dust collection function, which is not only labor-saving but also dust-free, and greatly protects the health of workers.

How to find a putty scraper?

Off-line mode: Go to some local gathering places of labor market and talent market, and then ask friends if there are any recommended workers, or go to some decoration companies and paint shops to ask.

Online mode: put the workers you need on some home improvement websites or apps for recruitment, or process more people to chat, ask questions, post and so on.

How much is the putty scraping?

One is contracting for materials, but generally, if you are not an acquaintance, you are unwilling to adopt the method of contracting for materials. Now owners with a little decoration experience don't like contracting, and the prices vary from place to place, generally around 15-25 yuan/square.

The other is to contract only the price, not the material price. Self-built houses in rural areas are scraped three times, the first time trachoma is filled, the second time leveling and the third time polishing. Total labor cost of three processes *** 12 yuan/square. In third-and fourth-tier cities, cleaning is generally around 20 yuan/square meter, plus polishing and painting, generally around 30 to 35 yuan/square meter.

Acceptance of scraping putty

Acceptance method

1, the simple and intuitive method is to rub it by hand to see if there is powder falling. It is recommended to shovel it carefully before sticking plaster. If it drops slightly, it is necessary to brush the wall curing agent to strengthen the strength of lime-sand brick base.

Knock on the wall with your hand to see if there is any empty drum. If there are few empty drums, repair them on the spot. If it is too much, it is recommended to shovel it and redo it.

acceptance standard

1, check whether the surface is dry.

Be bored with child to scrape two or three times, and then brush latex paint after polishing; In addition, if the putty is painted before it is dry, it will crack and peel easily in the future.

2. Check the surface for cracks.

Cracks on the surface of putty may be caused by many reasons, so be sure to check them carefully. If cracks are found, we must negotiate with the worker's master to solve the problem in time.

3, check whether it affects wood products.

If you scrape putty on wood products, it will affect the external light of wood products and must be removed in time. Top putty can also be accepted by this method.

4, check the flatness

When measuring with a guide rule, the wall and the guide rule should be closely seamless, and there can be an error of 2mm. It is better to rely on the acceptance of the "meter" shape.

5, check the Angle of Yin and Yang

Qualified putty layer should be on a straight line perpendicular to the ground, and no bending can be seen with eyes. Especially for the wall with wallpaper, if the angle of yin and yang is not straight, the wallpaper in these places will be hollowed out, and the later maintenance will be more troublesome.

6, check the polishing effect

Polishing the qualified putty surface with fine sandpaper will have the effect of metal reflection. Don't worry about coating or sticking. Only in this way can the coating be smooth and shiny.

7, check the stability performance

Sprinkle a layer of water on the dry putty in the mineral water bottle, and observe whether the putty is softened or crushed. If there is no white paste on the hand, the wall surface will not change much, indicating that the quality and stability of putty are good.

Matters needing attention in acceptance

After putty scraping, the wall surface should be solid, flat, vertical, free from cracks and holes, with uniform color and full paint film, and pay attention to the protection of finished products.
