Matters needing attention of painter scraping putty

Precautions for putty-scraping painters

Precautions for putty-scraping painters, when decorating walls, everyone has higher requirements. In home decoration, putty-scraping is a very skillful decoration. If the putty is scraped well, the wall will be very flat and smooth. Let's take a look at the precautions of the painter who scraped the putty. Precautions for painter scraping putty 1

1. Process and precautions for scraping putty

Because the house of the design elder sister's house is an old house reconstruction, the previous owner may have used more lime when decorating, and some old walls have already had sand, so these problematic walls were shoveled off and re-approved before scraping putty. After these basic works are completed, we will start the process of scraping putty.

1. Preparation for protection work

According to the normal construction steps, the floor tiles are usually pasted before putty scraping. In order to avoid dirt and damage to the floor during wall construction, it is necessary to protect the finished floor first, and the tiles pasted on the floor should be protected. Generally, the ground protection work can be done first after the floor tiles are attached and stabilized.

2. Check for hollowing

In order to prevent the wall from cracking due to the floating layer after the completion of the later wall construction, it is necessary to check whether there is hollowing or cracking of the wall plate before scraping putty, and if there is, it must be knocked down and re-floated.

3. Leveling treatment

In addition to the hollowing, it is necessary to knock it out and re-batch it. If the wall foundation is uneven, it is also necessary to repair the uneven wall before scraping the putty for the first time to make the wall foundation more flat.

4. Painting the wall and fixing it

This step is generally needed for renovation of old houses and poor wall foundation. Because my home is renovated from an old house, the treatment of the old wall surface is more complicated. It is necessary to brush a layer of wall solid on the original wall surface to make the old wall surface more dense and more adhesive.

5. Generally, the putty should be scraped three times, and the putty should be completely dried in the middle.

Generally, it should be scraped three times, the first time and the second time, the second time and the third time, and each time in the middle needs to wait for the previous round of putty to be completely dried before making the next step.

6. Polishing

After the putty is scraped, use a bright light bulb to obliquely illuminate the wall to see if there is any shadow. For uneven places, use small sandpaper to polish until the wall is completely flat.

7. Protective strips for the internal and external corners

In order to prevent the large pieces of external corners of the wall from being damaged and falling when moving furniture and the like collide in the later period, it is necessary to add protective strips for the external corners when scraping putty. In order to avoid cracking in the later stage, it is also suggested to hang a net or use a protective strip at the internal corner of the wall and woodworking ceiling.

8. Change the gate first or blow the putty first

Generally speaking, many people have to choose a date when changing the gate, which may not guarantee that the gate has been changed when blowing the putty. If the gate is changed at a later stage, the putty near the two sides of the gate can be scraped after the gate is installed.

9. Hanging the net

It is recommended to hang the fiber net when scraping putty for the new wall, which can prevent cracking to some extent.

putty is basically the above! Let's talk about matters related to brushing latex paint.

second, paint the wall with latex paint

After the putty is scraped and dried thoroughly, you can start the process of painting the wall. Before painting, it is recommended to install the wooden door first, so that the closing is easier to handle, and you are not afraid to brush the wall with latex paint when installing the door. Regarding the process and precautions of wall painting, after all, I have suffered a loss. Let me share some experiences.

after many comparisons and comprehensive consideration (mainly due to environmental protection factors), I chose the original imported latex paint from Shuna Vaughan, and I ordered it in a direct store in JD.COM, so I don't have to worry about fakes.

1. Protection

Doors and windows are protected with masking paper. Remember to tear off the wall almost after the construction is completed. After a long time, it is easy to leave residual glue. I just tore it late, and it was so hard to clean up the back.

2. Inspection and polishing

Before painting, it is necessary to check whether the putty on the wall is slightly uneven. If such problems are found, it is necessary to polish the wall flat.

3. Dust removal

This is the final preparation for latex paint construction. Dust particles on the wall surface can be removed by feather sweeping, and a vacuum cleaner can be used if necessary; This step is also very critical. If the dust on the wall is not cleaned up, the latex paint brushed will be prone to peeling and falling.

4. How many times is the latex paint brushed?

primer 1 time+topcoat 2 times. When you brush latex paint on the wall, after each brush, you should wait until it is dry before brushing it for the second time. In order to catch up with the construction period, if you brush it once before it is completely dry, it will easily crack and cause problems later. The proportion of latex paint mixed with water should also strictly abide by the instructions, otherwise there will be problems such as color difference and lacquering.

5. Construction of color matching wall

It is very popular to paint a wall with multiple colors, and it will also be designed by splicing geometric patterns. However, some workers may not have done this new construction method, including our workers who said it was the first time. Share the construction steps and precautions of my color matching wall! Determine the pattern and color scheme of wall painting, and mark it accordingly;

according to the geometric pattern of color matching, stick masking paper (or color separation paper) on the wall; Brush the light-colored part first, and tear off the textured paper when the light-colored paint is 7-8% dry;

When the light color is completely dried for the first time, you can repeat the above steps and brush the light color for the second time; When the light-colored part is completed, stick masking paper on the line position, then brush the dark part, and tear off the masking paper when the dark paint is 7-8% dry;

when the dark color is completely dried for the first time, you can repeat the steps to brush the dark color for the second time.

The whole construction step is complicated, so be careful not to tear the textured paper until it is completely dry. It is easy to tear off the paint film, which requires the patience of the construction master.

6. About touch-up paint and color difference

For colored latex, it is best to tone the color and construct it at one time to avoid color difference after multiple color adjustments. After brushing, you can save the paint for later touch-up. Dark paint touch-up is easy to have color difference, and touch-up may require repainting the whole wall; If the dark wall is located on the moving line of the moving furniture, if conditions permit, the dark wall can be painted after the furniture comes into play. The reason why this section is marked red is precisely because the blackboard wall of my house was knocked a little by the master who moved the washing machine. I used the paint left over from the original decoration to make up the paint, but it still made up the color difference, and finally I had to repaint it completely.

7, the practice of blackboard wall

There are children at home, so it is necessary to brush a blackboard wall in order to facilitate children's drawing and teaching children to learn. However, there are many problems that need to be paid attention to when brushing the blackboard wall, especially the blackboard paint other than black, because my household is the latex paint imported from Shuna Vaughan in JD.COM, so take this brand of wall paint as an example, and you can learn from my family's practice.

brush the primer;

Brush the ordinary colored topcoat twice, and mine is dark green; Brush transparent blackboard paint for 1-2 times. It should be noted that a section near the ceiling should be set aside to be brushed with a small brush to avoid dark paint or blackboard walls staining the white and clean ceiling. Precautions for painters who scrape putty 2

Step 1 for oilers to scrape putty: Check the original wall surface

If the wall surface is a cement wall, it is necessary to check the flatness of the wall surface and whether there are cracks, holes, etc. If necessary, use gypsum to level it first. If there is putty on the wall, it is necessary to check whether the putty is qualified water-resistant putty. If it is not, it must be shoveled off to redo the water-resistant putty. If the original putty is empty and cracked, it also needs to be shoveled off to redo it.

note: to check whether the putty is waterproof, you can splash some water on the wall first, and then rub it on the wall with your hands or wet rags to see if there is white ash on your hands or rags. If it is, it means that the putty is not waterproof and needs to be redone.

Step 2 of oil workers' putty scraping: Do the preparatory work well.

Before batch of putty scraping, it is necessary to ensure that the wall surface is solid, neat and flat, and if necessary, a layer of interface agent should be painted on the wall surface, and then plaster is used for leveling before putty scraping. At the same time, we should also do a good job in protecting the finished decoration products in the room to avoid getting dirty when scraping putty.

note: the main purpose of the interface agent is to clean up the dust of the wall and improve the adhesion between the wall and other decorative materials, so as to make the wall base more firm and avoid problems such as bulging and cracking after decoration.

Step 3 of oil workers scraping putty: Batch scraping water-resistant putty

Before scraping putty, measure the flatness of the wall to determine the method of scraping putty. In order to ensure the quality of the wall, qualified water-resistant putty should be selected. Generally, the putty can be scraped for 2-3 times on the wall. When scraping the putty for the second time, it is important to pay attention to leveling, especially to ensure that the angle of Yin and Yang is vertical, and the interval between batches of putty scraping each time should be more than 2 (after the surface is dry).

note: compared with water-resistant putty, water-resistant putty has long service life, is not easy to peel and crack, and has better environmental protection. However, it should be noted that the waterproof putty should not be scraped too thick every time it is constructed, otherwise it will crack during drying. Therefore, when the flatness of the wall surface is poor, it needs to be constructed many times, and even the thick bottom is made with gypsum first.

step 4 of oil workers scraping putty: polishing putty

water-resistant putty will become extremely solid after 5-7 days on the wall, and it will become extremely difficult to polish it again at this time. Therefore, it is recommended to start polishing putty 1-2 days after scraping putty. Polishing can be done at night, with a light bulb of more than 2 watts close to the wall for lighting (it is also necessary to use a light bulb for leveling during the day), and check the flatness while polishing.

The above is an introduction to the steps of putty scraping for oil workers, and I hope it will be helpful for you to scrape putty on the wall. The putty scraping on the wall depends not only on the quality of putty powder, but also on whether the construction technology of oil workers is professional and in line with the specifications. Therefore, I suggest that owners can conduct on-site inspections on their construction workers when choosing a decoration company. Precautions for putty-scraping painters 3

Precautions for putty-scraping

1. During wall decoration, it is necessary to pay attention to the wall foundation before putty-scraping. For example, if the old house is renovated, the original base must be removed; If a new house needs to check the thickness of the original foundation powder on the wall first, if it is wrinkled or empty after being brushed with water, the original wall powder base should be eradicated, and it is forbidden to treat the wall surface with glue.

2. When the grass-roots unit has strong absorbability, it should be sealed with primer before scraping putty, so as to avoid the rubber compound in putty being absorbed too much by the grass-roots unit and affecting the adhesion of putty.

3. In addition to the basic treatment, attention should also be paid to the crack prevention treatment of plasterboard, splint and wall before putty scraping. All seams and the depths of cracks in the wall are required to be gradually embedded with elastic putty, and under the premise of ensuring no gap, the cracks are pasted with cowhide bandage paper or white without white glue, and the large-scale batch embedding construction is carried out and the requirements of leveling are met; For the treatment of yin-yang angle, it is required to be vertical and straight.

4. Don't scrape and coat too much, so as to avoid skin rolling, falling off or squeezing out the rubber in the putty, and the sealed surface is not easy to dry.

5. In order to avoid excessive shrinkage, cracking and falling off of the putty, it is not too thick to scrape at one time. According to the characteristics of different putty, the thickness should be .5 ~ 1 mm.

6. The selected white cement and gypsum powder require the use of high-quality powder, which can fill the gap of self-made putty, ensure the smoothness of wall putty scraping and save latex paint. In addition, white latex or glue is properly added to the self-made putty, and the viscosity is appropriate and the glue is uniform.

7. Grasp the inclination of tools when scraping and coating, and apply force evenly to ensure the putty is full.

8. Choose appropriate putty and scraping tools according to the performance of the coating and the basic conditions. When filling holes and cracks at the basic level with a putty knife, press the blade with your forefinger, and press the putty into the defect hard. Fill it up and fill it up, and scrape the putty around it to minimize the traces of putty.

First, how to quickly dry putty powder in winter

First, the space for storing putty powder must be dry, and at the same time, a proper amount of desiccant should be placed beside it to absorb water and moisture in the ground and air, so that putty powder can dry faster; Secondly, when the weather is fine, the putty powder can be dried in the sun, which will dry faster. Note that if it is stored for a long time, it should be taken out and aired regularly to avoid affecting the performance.

second, what are the skills when scraping putty

1. Because the main purpose of putty is leveling, it belongs to the grass-roots work of the wall, so the construction must be carried out in accordance with the requirements of construction specifications, including whether the wall is flat, whether the wall is dry, and the proportion of putty powder, so as not to affect the construction quality.

2. Before scraping putty, the wall surface needs to be cleaned. In view of the obvious uneven position, it needs to be removed and filled first, and the putty will be smoother after construction. In addition, in order to ensure the adhesion of putty layer, each layer of putty needs to be polished after construction.

3. The thickness of putty scraping is also required. The thickness of scraping in a single batch should not exceed 2 cm, otherwise the putty layer is prone to cracking. And in the construction, it is necessary to measure whether the wall is dry, otherwise it will be empty or cracked.

4. When there is sand on the wall itself, a layer of interface agent must be painted on the wall before scraping putty, so as not to affect the construction quality of the putty layer.
