The gap in the home improvement gypsum board ceiling is to fill the gap first or glue the bandage fi

In the process of home decoration of plasterboard ceilings, it is more common to fill in the gaps first. This is because filling the gaps can provide a flat foundation for subsequent adhesive bandage work, so that the bandage can better adhere to the plasterboard, thus improving the overall stability and aesthetics of the ceiling.

With the decoration device, you only need to enter the area + city, and calculate the most affordable local market in 3 seconds**: [Tuba Rabbit Big Platform Counts**].

No longer worry about the company's price increase, omission and price increase.

In the process of filling the gaps, a special caulk is often used, which is able to tightly fill the gaps between the plasterboards, resulting in a flatter ceiling surface. The ** of the caulk will vary depending on the brand and quality, but generally speaking, the ** on the market is about 10 to 30 yuan per kilogram.

After filling the gaps, the next step is to glue the bandage. The function of the bandage is to enhance the stability of the gypsum board ceiling and prevent cracks in the ceiling due to the passage of time or the influence of external forces. The ** of the bandage will also vary depending on the brand and quality, but in general, the ** on the market is about 20 to 50 yuan per roll.

When working on plasterboard ceilings, it is advisable to choose better quality caulks and bandages, although this may add some costs, but in the long run, this can improve the life and aesthetics of the ceiling, thus avoiding the hassle of frequent repairs due to ceiling problems. At the same time, it is also recommended to follow the correct steps during the installation process, that is, to fill the gaps first, and then glue the bandages to ensure the quality and stability of the ceiling.

The process sequence is to caulk with gypsum powder putty first, and then paste anti-crack tape. I hope my answer can help you.

If it is a patch or paper tape, it should be caulked first. If the mesh belt is pasted, the tape can be pasted first and then caulked, so that the tensile force of the mesh belt bonding on the gypsum board is better, rather than sticking to the gypsum putty after caulking. Caulking materials can be putty with the addition of plaster and latex, reinforcement and ease and tensile strength.

It must be patched with caulking plaster first, and when the water is dry, kraft paper or bandages are pasted.

Laying direction, fixed transversely and longitudinally.

The strength performance and deformation of gypsum board are determined according to the direction, and the longitudinal performance of the board is superior to the transverse, so the longitudinal part of the gypsum board is not allowed to be parallel to the covered keel when the ceiling is suspended, and it should be perpendicular to the keel, which is an important measure to prevent deformation and cracking of joints.

When installing the partition board, it should be laid longitudinally, because the longitudinal length of the board is the same or close to the height of the floor, and it has the advantage of fixing with the vertical keel, and the longitudinally laid joints are conducive to improving the fire protection capacity.

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.

The joints of gypsum board should be caulked and pasted with caulking gypsum (also called quick-adhesive powder) on a firm foundation.

The specific steps are as follows:

1. On the solid base layer of gypsum board, ensure that the gap between the two gypsum boards is more than 5mm. If it is too small, you need to use a wallpaper knife to widen it into a V-shaped gap;

2. Fill the gaps with caulking gypsum and smooth them while ensuring that they cannot be higher than the gypsum board surface. After the caulking gypsum is dry, the next process will be carried out;

3. Paste the caulking tape: if it is a thick caulking tape, it needs to be soaked in water; The thin one can be directly brushed with white latex aqueous solution (appropriate or without water, depending on the existing white latex) paste; It is necessary to evenly brush the white latex on the surface of the caulking belt after pasting, and scrape the caulking tape smoothly;

4. Wait until the caulking tape coated with white latex is completely dry, and then scrape putty and other follow-up work.

2. Caulking gypsum dries quickly, and white latex can be added appropriately when adding water to prolong the drying time.

Here's how:

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

Now there are finished lines for sale, there are right-angle lines with yin and yang angles, and T-shaped lines, which are specially used to mend gypsum board joints, and the construction is very simple, just scrape putty directly when stuck in the gaps.

Method 1 is suitable for filling gaps in small areas, and method 2 is suitable for large areas.

Caulk (Lafarge Knauf and the like) mix the joints with glue, and pay attention to the spatula to be flattened. Check that all seams are caulked and wait until they are dry before roughly treating the lower surface, Lafarge and other brand bandages are soaked in water and covered with white latex paste, be sure to use a good bandage of the brand, otherwise it is very troublesome to rework. After drying, you can make putty as a whole, and the decoration company will ask for another caulk covering on the bandage, and the effect will be better.

First fill the flat with caulking plaster, and then seal the caulking tape on the face! Then you can batch the putty ......

First use a good point of caulking plaster to treat the base layer, after drying, the second treatment is leveled again, pay attention to the spatula to be flattened, and then use a good point of joint agent or white latex paper bandage bonding, pay attention not to ventilate in time, to close the treatment, and start to make putty after drying.

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.

Here's how to caulk and wrap up:

The required materials are as follows:

Tools such as trowels, blended plaster, paper tape, and knives.

1) The surface treatment of the plate seam is carried out first. Remove other substances such as floating dust and loose materials, and then use a trowel to apply the mixed gypsum caulking paste to the wedge-shaped edge joint, and the trowel will glue the seam paper tape firmly at the upper end.

2) Make the paper tape firmly stick to the gypsum board, apply the gypsum caulking paste thinly to the surface of the joint paper tape with a trowel knife, completely coat the joint paper tape, and scrape off the excess seam paste with a batch knife.

3) Use a trowel to apply a thin second layer of gypsum caulking paste, about 50 wide from the first layer on both sides, and then polish it with fine sandpaper after drying.

4) Evenly apply gypsum caulking paste on both sides of the yin corner, fold the seam paper tape in half and paste it into the yin corner, so that it is tightly embedded in the gypsum caulking paste.

Preparation of gypsum board:

1. Modified starch, retarder, pulp, water reducer and water are quantitatively measured and then put into a hydraulic pulper and stirred into raw material pulp, and then pumped into the pulp reserve tank for later use;

2. The foaming agent and water are put into the foaming agent preparation tank in proportion and stirred evenly, and pumped into the foaming agent reserve tank (with heating device, keep more than 35) for standby;

3. The raw materials of coagulant and gypsum powder enter the silo for standby through the lifting and conveying equipment.

When the indoor safety gypsum board ceiling is suspended, the gypsum board needs to be nailed to the keel. According to the relevant requirements, usually the gypsum board needs to be separated from the seams around it when it is installed, and the spacing between the edges of the board is about 3-5mm, so we need to carry out joint treatment after installing the gypsum board. What is the treatment method of gypsum board joints in suspended ceilings?

Next, I will briefly introduce it to you.

1. According to experts from Qeeka Home, special caulking materials should be used for gypsum board joints, such as caulking tape and caulking gypsum. If the caulking material is not of good quality, it will lead to cracking of the joints of the gypsum board; After selecting the best caulking material, you need to carry out the edge of the board first, and only this step is required for the general cutting edge of the board. We chamfer the edge of the front panel, and use a knife to pick and tear off the chamfered paper layer, but the plaster core cannot be exposed.

2. Next, we use a small spatula to fill the special caulking paste into the board joint; After the caulking paste is dry, we apply a layer of white latex, press the caulking paper tape into the base layer, and then apply a layer of white latex for repair and leveling; Finally, we hang the mesh cloth. After the gypsum board joints are treated, it is best to apply anti-rust oil at the nail hole to avoid rust on the screws; Then you can scrape putty, paint and other decorative gypsum board ceilings.

3. Ceiling-mounted gypsum board ceiling has the advantages of fire prevention, sound insulation, heat insulation, high strength, light weight and good stability; However, the moisture resistance of gypsum board ceilings is relatively poor, so it is best not to install gypsum board ceilings in bathrooms and kitchens. When you buy gypsum board, you can choose the market well-known, reputable brand products, the more well-known gypsum board Zhaoshan filial piety brand has Dragon brand, Knauf, Taishan gypsum, Jack and so on.

Summary: What is the treatment method for the joints of the ceiling gypsum only wide board, I will briefly introduce it to you here. I hope that after reading this article, I can provide you with reference and help when dealing with gypsum board joints in the future.

That is afraid of heat expansion and cold contraction, and the seam will soon crack again, and a tape can reduce the pulling force of heat expansion and cold contraction.

Gypsum board installation seam is a 100% wrong approach, gypsum board is a product with very small relative size deformation, and leaving a seam of 5mm means that the deformation of the gypsum board veneer is about 5mm, which is almost impossible.

So why is there such a construction requirement? In fact, it originated from the practice of Beijing in the 80s, when wooden keel ceilings and partition walls were used, and the shrinkage of wood was very powerful, so gypsum board naturally developed the practice of leaving seams. Now they are all light steel keel ceilings and partition walls, so there is no need to leave seams for a long time.

However, the current supervisors and other old experts still grasp the norms and do not let go.

Due to the large number of capillary pores and large specific surface area of gypsum board, it can absorb moisture when the air is too humid; When the air is too dry, moisture can be released, resulting in a deformation of more water and less water. In order to prevent the deformation of gypsum board, the main measures are to add slag, fly ash and other reactive mixed materials, or add waterproofing agents. However, it is also required to reserve construction joints during construction.

The general specification requires about 5mm! Prevent construction rework due to deformation!!

Generally, the joints of gypsum board ceilings are left in order to better prevent cracks in the future. Generally, the ceiling is made of gypsum board. That is to say, the inside is mainly gypsum, if you don't leave a share, when you put putty powder on it, you can't fill the gaps in the joints, and when there is a certain seam treatment, you can use gypsum powder to fill the joints and then paste the mesh cloth, which will better prevent the ceiling from cracking.

Basically, the purpose of 5mm-10mm is to resist the cracks of thermal expansion and cold contraction, and the ceiling should pay attention to a level regardless of the size of the area.

Prevent cracking, beautiful, decorative, easy to install.

Hot packing, cold shrinkage, 5 mm, white cloth or kraft paper will do.

Leaving joints is to better prevent cracks in the future, now the ceiling is generally made of gypsum board ceiling, that is, the inside of the panel is mainly gypsum, if there is no seam, when the putty powder is not carried blind, the gap in the knot can be filled with the glossy surface, and when there is a certain seam treatment, the gap is filled with gypsum powder in the mesh cloth, so as to better prevent the ceiling from cracking.
