How do you scrape putty on adobe walls? How to scrape putty on the earthen wall of the cave

1. Check in advance: check the condition of the base layer of the existing wall, if the putty has poor water resistance and poor gypsum curing strength, the gypsum putty layer needs to be removed, and then the gypsum and water-resistant putty are scraped again; Check whether there are delamination hollows, cracks, and cracks on the wall, and if these are present, you need to remove the problematic places. After the anti-cracking treatment, the gypsum putty is scraped again; (excluding the case of the first article of the total eradication); Check the condition of the light body wall and load-bearing wall on the wall.

The place where the light wall and the load-bearing wall meet, the place where the light wall and the light wall meet, the place where the light wall and the top meet, and the place where there are construction holes are treated with anti-cracking.

2. The basic procedure of scraping putty is: cement mortar plastering and leveling (the wall should be sprinkled with water before leveling, and it should be dried after leveling); Do the corresponding position of anti-crack treatment (patch, anti-crack bandage, caulking cement mortar or caulking plaster, etc., according to the specific situation to choose the appropriate anti-crack treatment); Painting interface agent (wall shovel), plaster leveling (wait for the plaster to dry before doing follow-up work); Batch scraping water-resistant putty, after the putty is dry, do fine grinding and leveling; Apply the interface agent, then the primer and top coat (or apply the base film and wallpaper).

The renovation of adobe walls and the renovation of old houses were originally the problems of scraping putty on the walls of adobe structures: 1. The first floor is generally damp, but there should be room for improvement; e.g. whether the branches outside the building can be pruned; Whether the drainage ditch outside the building can be dug deeper, at least lower than the indoor ground; Open more windows on sunny days, etc.; (Find out more about the reasons and improve it from the source).

1. Check the condition of the soil wall first, you need to understand the firmness of the soil wall, water resistance, etc., and at the same time check whether the soil layer has cracking, hollowing and other problems. 2. The putty itself has a certain degree of adhesion, but it will not be too high, especially for the soil wall, which is easy to fall off the wall, the adhesion is definitely insufficient, if it is scraped directly, the possibility of falling off in the later stage is great. And it is best to scrape a layer of cement mortar on the earthen wall first to prevent useless work in the future.

Relevant knowledge development materials: 1. The cement layer of the soil wall does not need to be too delicate, and as long as the cohesiveness is ensured. If there is cracking in the earthen wall, the cement layer can be used with fiberglass mesh to repair the wall surface and avoid further cracking.

2. After the cement layer is dry, you can scrape the gypsum putty on it for leveling, ensure that it is coated and scraped evenly, polish it smoothly after drying, continue to scrape a layer of water-resistant putty, and wait for it to dry to carry out fine grinding, which is the key to ensuring the beauty of the wall. In the later stage, you can paint latex paint or paste wallpaper to decorate according to your needs. 3. If the construction base has strong absorption, it is necessary to close it first to avoid the putty being scraped and the moisture being absorbed by the wall, and the putty will be directly pulverized and peeled off.

This kind of base layer can be blindly painted with more base sealing paint to ensure the adhesion of putty. 4. If you want to scrape the putty, you must master the batch scraping angle, the scraper should be inclined at 45 degrees, and the force should be uniform, so as to ensure that the thickness of the putty layer is consistent. 5. The putty scraped on the wall can not be too thick, nor too thin, if it is too thin, it is easy to fall off and peel, if it is too thick, it will dry slowly, and it will be easy to crack if you don't pay attention.

The detailed steps to scrape putty are as follows:

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, smooth the protrusion, and fill the depression.

2. Do the repair of the grassroots:

After the base layer is treated, there will still be some depressions on the wall, 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 alkali 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.

Notes:

Kitchen and bathroom: the wall that needs to be tiled is sealed with a light steel keel cement pressure plate, and then the steel wire mesh is hung to make a waterproof layer; After passing the closed water test for 24-48 hours, the wall tiles can be pasted;

Wooden keel gypsum board ceiling, plane or shape according to the design plan, and then batch ash brush latex paint; Kitchen and bathroom top plastic steel or aluminum gusset ceiling; Doors and windows: generally cocoa can be installed directly; Cabinets, lamps, regular installation is sufficient.

First use a good glue as an interface agent, and do it heavily on top of the adobe, after drying, the adobe will not lose powder and can be sticky. After leveling with mortar, you can scrape putty. Be sure to use a good construction glue, you can mix some white latex in it.

Will drop! You might as well seal it with drywall!

Cement wall scraping putty is an important process in decoration, mainly to make the wall smooth and flat, improve the aesthetics of the wall, let's introduce the method of scraping putty on the cement wall:

1. Wall treatment: Before scraping putty, you need to treat the wall first, remove the loose matter or dust on the wall, and then use sandpaper to polish the wall to make the wall smooth and flat.

2. Putty: When preparing putty, it is necessary to mix and mix the putty and water thoroughly according to the instructions on the package, until the texture of the putty is uniform, without any particles and lumps.

3. Scrape putty: pour the stirred putty on the scraper, and use the scraper to scrape the putty evenly on the wall, taking care not to scrape too thick at one time, so as not to dry for too long, and not to scrape too thin, so as not to affect the effect.

4. Polishing: After waiting for the putty to dry, polish the wall with sandpaper, and polish the wall to make it smooth and smooth to achieve the desired effect.

It should be noted that when using putty, it is necessary to avoid coating the putty too thick or too thin, which is easy to crack and is easy to have poor moisture-proof performance if it is too thin. In addition, during the process of scraping putty, it is necessary to maintain a certain speed and direction to avoid irregular scratches. Finally, keep the walls dry and ventilated to avoid blistering or putty cracking.

If you want to make the wall have a better decoration effect, you can passScrape puttyto finish. As a slurry paint, putty can be used to make the wall smoother, which can improve the effect of latex paint, don't ignore it because putty is inconspicuous, it is very important! Next, Zheng Na will learn the steps of scraping putty with us!

Introduction to the steps of scraping putty:

Step 1: Treatment of the base layer of the wall

Different wall base layers have different construction requirements when carrying out base treatment.

For cast-in-place concrete walls, because the wall often has some porosity and bulging phenomenon, it is necessary to repair the wall surface, the protrusion should be smoothed, and the depression should be filled.

For precast concrete floor slabs, there are often some gravel and bumps on the surface, so professional construction personnel need to brush the wall as a whole with a wire brush to remove these debris.

For the cement mortar paper reinforcement ash surface layer, the surface of the wall is required to be dry, solid, clean, and free of oil stains.

Step 2: Repair the base layer of the wall

After the treatment of the wall base layer, there will still be some large wall depressions, so it is necessary to use gypsum putty to preliminarily fill these depressions. When preparing gypsum putty, the weight ratio of gypsum, emulsion and cellulose aqueous solution (concentration 5) is about 100:5:

60. Compact the gypsum putty with a steel scraper in the depression of the wall, and wipe the erected batch scraper again to ensure that the wall is smooth.

Step 3: Brush the caustic alkali aqueous solution

The main purpose of brushing caustic alkali aqueous solution is to clean the oil stain on the concrete wall. If you are using a 5% caustic soda solution, you need to apply it twice, and if you are applying a 10% solution, then you can apply it once.

Step 4: Brush the binder

Before the formal batch of putty, it is also necessary to spray the binder first, and the counterweight ratio of water to binder is about 100:15.

Step 5: Scrape the large white putty

When preparing putty, the weight ratio of large white powder, talcum powder, cellulose aqueous solution (concentration of 5) and emulsion is generally about 60:40:75:

3。When scraping putty, it is necessary to use the steel scraper to connect the wrong batch scraping up and down, left and right, and be sure to avoid leaving floating putty and scratches on the wall, and at the same time, pay attention to prevent the putty from being stained with dust, gravel and other debris.

Step 6: Polishing and repairing

After the first batch of putty is scraped, you need to check whether there is still a problem in the previously repaired area. If there is no problem, after the putty is dry, you need to use fine sandpaper to polish the entire wall, and after sanding, clean the wall. If there are still dents in these parts of the wall, then it is necessary to repair and level again with putty.

Step 7: Putty is finished

The batch scraping of putty generally needs to be carried out two to three times, and the putty of the last pass must wait until the putty of the previous one is completely dry before carrying out the construction operation. After the putty is scraped, the whole wall is required to be smooth and smooth, with uniform texture and no scratches on the surface, otherwise the overall decoration effect will be seriously affected when the latex paint is painted in the later stage.

Steps to scrape puttyThat's it.

Zhang bought a house and prepared to scrape putty on the walls by himself, which is really not an easy thing, unless you are really determined to do it yourself, you should hire someone.

A 100 square meter house takes 4-7 days to complete.

Tools & Materials: Fine Powder (for indoor latex paint), tray, scraper, mixer, cone, broom, cloth, water.

Sandpaper (250 mesh, 360 mesh, 400 mesh), sandpaper holder, ruler, solar lamp lighting.

Masks, hats, old clothes.

Steps to scrape putty on the wall by yourself:

1.Walls should be cleaned, especially small stones on the walls. The easiest way is to scratch the sides with a palette.

The stones are basically gone, and then there will be floating ashes that can be cleaned with a broom or cloth. You can even use a hair dryer——。 However, after this blow, the visibility of the room whisperers will be very low.

Steps to scrape putty on the wall by yourself:

2.Use the tool.

It is best not to use hand glue such as wooden sticks unless it is used on a small area. If you work in a large area, you must use power tools. There are many special tools that can be sold on the internet, but it is not recommended to buy them.

If you decorate your house, you should have a hammer. At this time, you can buy a rod to remove (be sure to pay attention to the board when buying a bar).

Steps to scrape putty on the wall by yourself:

3.Start stirring, remembering one principle: add powder to the water. Once added, start stirring and stir for about 2 minutes. When shaking, shake the tamper so that all parts are evenly stirred.

4.Check whether the putty is qualified. Place the putty on the tray and the trowel is basically horizontal. The putty doesn't fall off in a few seconds, which is very good.

On the wall, for the first time two points are asked: do not come down, that is, after this time, you do not see the gray cement No. 2, try to keep it flat. It's not hard to ask these two.

5.Grinding, for the first time, you can polish the putty after drying. If it's hot, it dries out in five or six hours.

The first polish, it can use 250 mesh, it looks rough, but it doesn't matter. Because there is a second layer of putty. The grinding point is to rub the top at the seam, try to keep it level, here you should use rules and sunlight, do not use too much force, or pass through the putty.

Steps to scrape putty on the wall by yourself:

6.Clean the walls, use a broom or a hair dryer – a hair dryer is recommended, although it is very dirty.

7.The second time putty, the layer can not be too thick, see where the building requirements, it seems to be about 3mm, the main purpose is to collect light, flatness, processing, so this time, carefully do it, try not to leave holes and vents.

8.Clean the walls.

Inspect the wall and if there are holes, use a scraper to repair and polish.
