If the plasterboard is cracked, what will be used to repair it so that it will not crack again?

The methods mentioned in the previous few can solve the problem, but to make both specimens, you need to understand what causes the cracks: What is the keel of gypsum board? Is it a wooden keel or a light steel keel, I suggest that you push it hard in the place where there is a seam, whether the nail connecting the gypsum board is loose, or the keel deformation (wooden keel) falls, and the resulting gypsum board and the base layer are not fixed to produce cracks, and the analysis draws the correct conclusion, then you can prescribe the medicine, first of all, the cracks should be fixed with drywall nails (self-tapping), and then use high-quality gypsum powder (you can buy it in a regular building materials supermarket:

Home Depot, a lot of gypsum powder in the market has a small amount of large white powder) + a small amount of white latex (dilute the white latex with warm water to the point that you can hear the sound of swishing, do not add cellulose), stir into gypsum filling putty, carry out crack slotting treatment, filling, repair and flattening, caulking belt + high-quality white latex seam treatment, after drying, it is OK to deal with it according to the methods of the above friends, I hope my experience will help you!

The construction party cut corners, and the improper ratio of materials and water during construction will cause this result. You can ask the decoration company or find some roadside masters, if the crack is not serious, you can re-repair it with double flying powder, if it is serious, you must remove it and redo it to avoid cracking and expanding, causing the ceiling to fall. Be sure to pay attention to safety!

You have to change the block again. Or just stare at it with a big picture.

Summary. If you hang the net again, it will not crack at all.

How to deal with the joints of plasterboard and walls to ensure that they will not crack?

Got this issue.

1. You can use plaster or putty to deal with the cracked parts of gypsum board, but you should pay attention to the amount of distraction when packing. 2. During construction, prepare an appropriate amount of gypsum and fill it into the cracked part of the joint until it is tightly filled. Then hang a good cloth at the seam to keep the flatness of the cloth; Finally, scrape a layer of putty and you're good to go.

Doing so is still cracking.

If you hang the net again, it will not crack at all.

100% won't crack.

The material must choose a good product.

I mean the drywall cracks in the dark corners of the wall.

The base treatment must be clean, and the keel must be flat. 22:09Bai Cheng XiaoshengThese are very important details.

1. When choosing the partition wall and ceiling skeleton, it is best to use a light steel keel. When choosing, you should also pay attention to not choosing those skeletons that are easy to twist and have bad lines, that is to say, the performance of the light steel keel must be able to meet the standard, so as to ensure that there will be no bending and warping in the decoration process. If there is a problem of one kind or another in the light steel keel, cracks in the gypsum board are inevitable.

2. After the installation of the keel, it must be flat, so that the force of the gypsum board will be balanced after installation. If the stress is even, the board wall is not easy to crack. Sometimes when laying the wall, you will encounter some building protrusions, such as pipes, if you can avoid it is the best, you can't avoid taking some special measures, and you can't force construction.

3. Strictly control the construction process to ensure that the project is constructed in accordance with the order of the specification. If there is a fire protection system, pipeline system, etc. in the gypsum board wall, it is necessary to wait for the system to have no problems before carrying out the gypsum board wall construction, so as to avoid the impact of moisture leakage on the wall, and to prevent the impact on the wall when repairing other systems.

4. The caulking material of gypsum board wall should ensure the quality, which is the top priority of joint cracking. Many caulking materials are not as strong and viscous as possible, and their compliance with the gaps is not high enough, so seams are unavoidable.

In construction, it is easy to ignore the importance of leveling putty, but its advantages and disadvantages also have an important impact on the cracking of joints. If the leveling putty has a large change in force and is brittle, cracks are also easy to appear.

In the specific construction, must be strictly with reference to the drawings and standards for construction operations, must pay attention to the distance between the suspension bar and the large keel, after installation, the keel in addition to its own weight, should remain stress-free, the construction process must pay attention to the acceptance of the intermediate links, for the investigation and handling of the problem must be rectified in time.

In addition, when doing the arching of the ceiling, it must be strictly in accordance with the regulations to avoid uneven stress. When encountering the "three seams", the main keel and the auxiliary keel should be disconnected to do, and the two parts are self-contained"Three seams"Leave the seams and then decorate the gaps with other materials.

When installing gypsum board, at the junction of the wall and gypsum board, open a groove of 2 cm into the wall, and the gypsum board is sunk into the groove when installing.

Now that I'm going to explain to you why we need to leave gaps, any material is shrinkable in itself.

It will occur in the case of different temperatures and humidity.

The most common occurrence is the change of the four seasons in the first year after the decoration, which has an impact on the materials used in the first decoration.

After the year, when the material has adapted to the ambient air temperature, there are very few problems.

Cracking of walls is a common phenomenon.

Fiber cloth is used to level gaps. After that, we scrape the putty because we leave shrinkage joints, so even if the plasterboard expands, it will not crack the surface wall.

On the contrary, shrinkage, there is a shrinkage material such as fiber cloth on the surface, and the finishing layer is rarely affected.

I used the seam specialist to crack.

Mix white latex or polyethylene glue with gypsum powder, but now there are anti-cracking products on the market that do not need to be adjusted, but the ** is relatively high. And the effect is not as good as gypsum powder, fill the gaps after adjusting evenly, and then paste gauze tape on the outside (kraft paper is better than gauze tape, there is a new type of fiberglass mesh belt), and then scrape putty.

First of all, when laying gypsum board, it is necessary to pay attention to control the gap between the gypsum board at 3-5mm. In this way, it is more convenient to deal with the gap in the back. You may wonder, isn't it true that the smaller the seam, the better?

In fact, no matter how small the seam you leave is, there will always be a gap, and it must be processed later. If the gap is too small, it will increase the difficulty of handling. Moreover, gypsum board will expand and contract, so you need to leave some space for it.

If the reserved seam is too small, don't worry. Use a utility knife to cut the joints of the two plasterboards out of a V-shaped groove.

After that, we first fill the gaps with putty powder, remember to compact a little to ensure that the gaps are filled and there are no empty spaces. The height should not exceed the drywall, and the surface should be scraped flat, and there should be no protrusions.

Then use white latex to apply the masking paper to the gaps. In addition to masking paper, you can also use strips of cloth (the best of good fabrics), gauze or special caulking tape. It depends on your choice, in fact, if you handle it well, there is not much difference between them.

Wait until the adhesive masking paper is dry, continue to apply a layer of milky white glue to the surface of the masking paper, which will be more firm. After that, hang the putty again, trying to ensure that the height of the caulking is not higher than the drywall. Finally, remember to sand the surface a little more to ensure that it is flat.

If necessary, you can also apply another layer of latex paint.

This is the normal treatment of the joints of two pieces of gypsum board, and then let's talk about the joint treatment of gypsum board and the wall.

At the junction of the wall and the drywall, we need to make a groove of about 50px into the wall. The plasterboard then snaps directly into the groove when it is installed. After the installation is completed, follow the same method above, smooth the gap with putty, stick the junction with gauze, and then scrape the putty, so that the problem of the gap can be solved.

That's all there is to know about drywall joint treatment, I hope it will help you.

Method: When carrying out the construction of gypsum board ceiling, about 1 2cm expansion joints should be left between gypsum boards, gypsum boards and walls, and the gaps should be filled with putty first, and then double pasted with cloth strips, and then scraped putty. The wooden keel used in the ceiling must be firm during construction, and there can be no loosening, which can prevent cracks in the gypsum board ceiling.

In addition, when bonding the negative corners of gypsum, it is necessary to leave a gap of about 0 5cm with the top surface and the wall surface, and use gypsum powder and latex to reconcile and fill the joints to prevent the gypsum line from cracking.

Gypsum board is a material made of building gypsum as the main raw material. It is a kind of building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance, etc., and is one of the new lightweight boards that are currently focused on development. Gypsum board has been widely used in the interior partition walls of various buildings such as residences, office buildings, shops, hotels and industrial plants, wall cladding panels (instead of wall plastering layers), ceilings, sound-absorbing panels, ground base panels and various decorative panels.

The treatment method of gypsum board joints is as follows: There are three forms of gypsum board wall joints, namely flat joints, concave joints and strip joints. Generally, there are more flat seams, which can be handled according to the following procedures:

1. When the gypsum board is installed, the joints should be properly left (generally 3 6mm), and the groove must be connected with the groove. After the floating soil in the joint is removed, brush a 50% concentration of 107 glue solution. 2. Use a small scraper to embed the wkf seam putty into the plate seam, and the plate seam should be embedded with the embedded solid, and the corrugator should be scraped flat.

After the putty is dry, check whether there are cracks at the caulking, and if there are cracks, analyze the cause and re-caulk. 3. Scrape the wkf putty about lmm thick at the groove of the joint, then paste the fiberglass tape, compact and scrape flat. 4. When the putty begins to solidify and is still in a wet state, scrape another piece of WKF putty, bury the glass fiber tape into the putty, and fill the plate gap and scrape it flat.

If the plasterboard is cracked, what will be used to repair it so that it will not crack again?

1. If the gypsum board is cracked, what will it not crack again after repairing it 1. If there are cracks in the gypsum board, we first need to repair the cracks and clean them up. Next, the gaps created by the plasterboard are wet with water, and then the mixture of plaster and water is poured. 2. Use this mixture to fill the gap directly, if the gap is relatively large, prepare a new gypsum board, cut it according to the cracks generated, and then prepare the screws of the steel plate to fix it.

Finally, apply the plaster, wait until it is dry, and then do a leveling, basically wipe it twice, apply the primer, and wait until it is dry, and then carry out the gypsum board latex paint painting, which can achieve the effect of repair.

Hello, I'm glad to answer for you, according to the relevant information found by the wild wheel, the gypsum board cracks are generally repaired with putty, and the specific steps are as follows: 1. Clean the cracks: scrub the cracks with a damp cloth to remove the dust, oil and other debris in the cracks; 2. Fill cracks:

Use a putty brush to fill the putty into the cracks; 3. Smoothing: use your fingers to smooth the putty to make it smooth; 4. Brushing: Dip the putty with a brush and brush a layer around the crack to make the putty perfectly combined with the surface of the gypsum board; 5. Drying:

Wait for the putty to dry completely, and then the patching job can be completed.

Summary. Dear, hello, I am glad to answer for you 1, first clean up the debris on the surface of the gypsum board, and then brush the surface gaps of the shallow gypsum board with soft bristles; 2. Apply an appropriate amount of slurry to the cracks with a scraper and fill the small gaps flatly; 3. Fill the deep gaps with the same slurry and completely seal the gaps; 4. Wipe off the excess slurry with a dry cloth to avoid accumulation; 5. Smooth the surface of the gypsum board to make the adjacent gypsum board face smooth and seamless; 6. Wait until the slurry on the surface becomes hard, and then use cloth to solidify the slurry on the surface; 7. The maintenance of gypsum board should be well protected when in use, and it should not be collided, and if any surface is cracked, it should be treated and repaired in time to maintain the beauty of gypsum board.

Done or cracked.

Even if the above repairs are made, there is no guarantee that the crack will disappear completely, but the damage can make it less noticeable. The best way is to replace the gypsum board, so that the width can effectively ensure the safe use of the gypsum board.
