How to scrape putty ash well

Scraping putty powder directly on the ecological board is prone to falling off (ash), so it is necessary to lay the foundation first.

Good results can be achieved by following the following construction steps:

1. There are gaps in the ecological board (plate) to be caulked. It is recommended to use the carf board worry-free toughness caulk for caulking, and then paste the seam tape (the master understands).

2. If the putty powder is scraped directly on the ecological board (plate) is easy to fall off (ash falling), it is recommended to use the home taxi board worry-free putty batch scraping for priming (TB), and then scrape the putty powder after drying.

First of all, put the product in the bucket according to the proportion, and then pour the appropriate putty powder into the bucket. Stir well with an electric drill, then clean the wall with a broom and putty knife, and repair the unevenness with gypsum powder.

Then scrape it vigorously and evenly to clean the extra putty. Finally, the putty needs to be scraped three times, and each time you have to wait for the last time to dry before you can do the next one.

When the absorption is strong, it is necessary to carry out a closed treatment, so as to prevent the base layer from being absorbed in large quantities, which can also affect its adhesion. At the same time, the clarity of the tool should also be controlled, and the force should also be done in Wuxi when carrying out construction, so as to ensure its fullness.

1. Do grassroots treatment.

Scraping putty has different requirements for different walls, like the more common concrete wall, there will be some porosity and bulging phenomenon, so it is necessary to smooth out the wall first, grind the bulge, and fill the depression. If it is a precast concrete wall, then its surface layer will have some grit and pimples, at this time, professional construction personnel are needed to use a wire brush to brush the wall as a whole.

2. Do the repair of the grassroots.

After the base layer is treated, there will still be a celery wheel on the wall without some depressions, and you can use gypsum putty to fill it at this time. Compact the plaster putty into the depression, wipe the vertical area and scrape it again to ensure the smoothness of the wall.

3. Brush the wall with caustic aqueous solution.

There may be oil stains and other things on the wall, so you need to paint a caustic soda aqueous solution, but you must pay attention to it when painting, and clean the wall with water while painting, which can not only speed up a little, but also have a good effect.

4. Start scraping putty.

Before scraping the putty, spray the binder once and you can start scraping the putty. Pay attention when scraping putty, avoid leaving floating putty and scratches, prevent dust, grit and other debris on the putty, and then scrape it according to the specifications.

5. Grinding and repairing.

After the first putty is scraped, carefully check to see if there is any problem with the wall, wait until the putty is completely dry, carefully polish it with fine sandpaper, if there is still a dent, then use putty to repair and level again.

6. Scraping putty is completed.

After the whole process, the state of the wall should be smooth and smooth, the texture should be uniform, and the surface of the wall should be scratch-free, otherwise it will affect the overall decoration effect.

Hello, dear, I'm glad to answer for you: how to scrape putty on the old lime wall so that it won't fall off? A:

Kiss the practice of brushing 801 glue insurance and clean up the floating ash: remove the old lime wall, and then the putty will not fall off. Here's how:

1. How to scrape the putty wall firmly - remove the skin of the wall, you can do a light water test to verify whether the adhesion of the original coating is qualified, and most of the walls are one word after inspection: shovel! 2. How to scrape the putty wall firmly - close the wall again with 801 glue.

3. The purpose is to improve the bonding between putty and wall, if you encounter an old house, you can increase the insurance factor by refreshing the interface**. 4. The negative angle deals with the "elastic line" on both sides (pay attention to the verticality), and the positive angle can be operated with a lever, gypsum putty is added with gypsum powder and glue 801, in general, it is not recommended to use the gypsum line. 5. Leveling the wall, first check whether the wall has a "hollow drum" (you can touch it, hear the sound), then use a slightly longer aluminum rule to check the grooves on the top and the wall, check, use a flat gypsum putty pad 6, formally scrape the putty, after the plaster putty is dry, apply the putty (dry thoroughly each time), there are two ways to verify whether the putty is dry:

First, observe whether the color is consistent, and then, observe that there is no "sticking" phenomenon when grinding. 7. Strong light is tilted and polished, and the top surface can be made of 360 sandpaper. 8. The wall must be basically dry, and the moisture content of the base layer shall not exceed 10%.

9. The plastering action has been completed, the wall pipes, holes, yin and yang corners should be treated in advance, and all types of holes in the wall must be pre-applied to ensure that the wall surface is dry. 10. Before building a large area, the model house should be prepared in advance, and after passing the inspection and evaluation of Part A and the supervisor, the equipment should be organized for large-scale construction. 11. The inner wall putty monomer is made of materials produced by the same manufacturer and prepared as much as possible to avoid color differences after using the materials.

The only way to scrape putty on the woodworking board and brush latex paint is to add a layer of gypsum board, and then scrape the putty and paint.

Woodworking board, the full name of blockboard, commonly known as large core board, wood core board, is made of two pieces of veneer in the middle of the glue splicing board.

When scraping latex paint putty, the water-based putty used must be able to absorb latex paint, and the wooden surface will be wrapped and peeled off due to contact with moisture. Therefore, it is not possible to scrape putty and brush latex paint directly on the surface of the blockboard. However, you can choose to add a layer of low-cost gypsum board to solve this problem perfectly.

Gypsum board is a board made of building gypsum as the main raw material, mixed with an appropriate amount of additives and fibers to make the core, and a special board paper as the surface protection. Gypsum board has the characteristics of light weight, sound insulation, heat insulation, strong processing performance and simple construction method.

The paper surface of gypsum board can be fully bonded with water-based putty powder, which is not easy to blister and peel off, and is a high-quality substrate for scraping putty and brushing latex paint.

Precautions: When using blockboard ceilings and partition walls, if you need latex paint effect, the construction plan must reserve the construction thickness of gypsum board, and then arrange putty scraping and painting.

Follow these steps to achieve good results:

1. There are gaps in the woodworking board (board) to be caulked. It is recommended to use a carb for caulking (on TB), which has toughness and can reduce cracking. Allow to dry before attaching the seam tape.

2. Scrape putty powder directly on the woodworking board (board) is easy to fall off, and it is recommended to use the worry-free putty scraping of the home board for priming (TB), and then scrape the putty powder (2-3 times) after drying. If you want to apply latex paint, proceed to the following process.

3. After the surface of the putty layer is polished, apply latex paint.

Overview of experience Wall auspicious scraping putty is an important part of ensuring the quality of interior decoration, now only on the operation steps of scraping putty briefly introduced:

Steps Method Shovel wall skin.

You can do a slight moisturizing experiment, rubber to test whether the adhesion of the original coating is qualified, and the vast majority of the wall surface has been inspected in one word: shovel!

The wall is closed with 801 glue once.

The purpose is to enhance the adhesion between the putty and the wall. If you encounter an old house, you can brush the interface agent to increase the insurance factor.

The yin angle is treated on both sides of the "elastic line" (pay attention to the verticality), and the yang angle is processed with a leaning rod.

Use gypsum powder and 801 glue to prepare gypsum putty, and straighten all the gypsum putty. In general, plaster lines are not recommended.

Wall leveling. First, check whether the wall has a "hollow drum" (can be struck, listen to the sound to judge), and then use a slightly longer aluminum alloy ruler to check the top and the depression of the wall, mark it, and flatten it with gypsum putty.

Officially scrape putty.

After the plaster putty is dry, scrape the putty (it must be thoroughly dried each time).

There are two ways to test whether the putty is dry: first, observe whether the color is consistent; The second is to see if there is a phenomenon of "sticking sandpaper" when sanding.

Strong light oblique grinding, the top surface can be 360 sandpaper.
