How to choose drywall? How to choose a good drywall

Look at the thickness, look at the flatness.

Look at the brand, Taishan gypsum board is very good. It is recommended that you buy a two-meter four, three-meter board is not good for unloading.

Nowadays, basically families will use gypsum ceilings to decorate their houses when decorating their houses, which can increase the beauty of the room. So how to choose a good drywall? Next, I will take you to find out.

1. When buying gypsum board, you can gently tap the surface of the gypsum board with your hands and listen to the sound it makes. Generally speaking, if the quality of the drywall is relatively high, it will make a crisp sound; However, if the sound is relatively empty, it means that the quality of the gypsum board is relatively poor, and it is very likely that the production is not standardized, and there is a space phenomenon.

2. The surface of gypsum board is very delicate, and the surface of gypsum board can be found to be shiny by observing it with the naked eye. For some inferior products, not only the surface looks very rough, and the color is very uneven, if it is decorated in the home decoration, the effect will be greatly reduced, which is not conducive to long-term use.

3. There is another factor that can judge the quality of gypsum board, that is, the surface and thickness of gypsum board. If it is high-quality, high-quality gypsum board, the thickness is up to standard, so that it has a very high stability performance, and the service life will be relatively long, and some relatively thin gypsum board will not take long.

Gypsum board is one of the most used materials in home decoration. But after the home renovation is completed, it is difficult for us to see it again. Of all the plates, it is the one that hides itself the most.

Perhaps because it is relatively cheap, people can not only decorate gypsum board, but also play a role in moisture-proof and sound insulation because of different classifications.

The quality of gypsum board does not lie so much in its main raw material, gypsum, but in the layer of paper attached to the surface of the board. Anyone who has ever used gypsum board knows that if the layer of paper on the surface of the board is scratched, then the plasterboard is easy to break, and the break is the same as the broken mouth of the paper.

Therefore, the strength of gypsum board actually lies in the toughness and adhesion of the paper on its surface. Good drywall, that layer of paper is specially treated.

Gypsum board should also pay attention to the system, when choosing gypsum board, in addition to paying attention to its own quality, should also pay attention to whether the entire installation has a complete system, this system includes: a variety of accessories, tools and construction methods. If this system is perfect, the best results can be achieved after the plasterboard is laid.

There are many types of plasterboard. It is widely used, as a consumer, we must learn to identify the quality of gypsum board when purchasing, generally in the following ways:

1) Visual inspection. During the appearance inspection, the front of the board should be visually inspected under the condition of bright light at a distance of o 5m, first look at the surface, the surface is smooth and smooth, and there can be no pores, stains, cracks, missing corners, uneven colors and incomplete cases, and the upper and lower layers of kraft paper on the gypsum board need to be strong to prevent cracking and not crack the gypsum board when screwing; Look at the side again. See whether the gypsum texture is dense and whether there is any hollowing phenomenon, the denser the gypsum board, the more durable.

2) Tap with your hands.

Check the elasticity of the drywall. Hit it with your hand, make a very solid sound, indicating that the gypsum board is strong and durable, if it makes a very empty sound, it means that there is a hollow drum phenomenon in the board, and the texture is not good. The weight of the plasterboard can also be measured by hand.

3) Allowable deviation of dimensions, flatness and right-angle deviation.

The allowable deviation of size, flatness and right-angle deviation should meet the qualified standards, if the deviation of decorative gypsum board is too large, it will make the decorative surface joints untidy, and the entire surface will be uneven, which will have a great impact on the decorative effect.

4) Look at the signs.

On each box, there should be the name of the product, trademark, quality grade, manufacturer name, production date, moisture-proof, care and product marking. When purchasing, it is important to look at the quality grade mark. The quality grade of decorative gyplight is divided according to the allowable deviation of the dimensions, flatness and deviation at right angles.

1) Look at the brand and logo of gypsum board.

The selection of gypsum board must identify the big brands, their quality is excellent, can ensure the normal progress of the project. To choose a regular gypsum board, you also need to look at the logo of the product, which is generally marked on its packaging box with a very clear name, production date and quality grade, etc.

2) See if there is any deviation in the size of the gypsum board.

When buying gypsum board, we should pay attention to the size, and there will be more or less deviations between its actual size and the normal standard size. If the deviation is small, the quality of the drywall is good; If the deviation is large, it indicates that the quality of the drywall is poor.

3) Check the appearance and performance of the drywall.

When choosing gypsum board, it is necessary to see whether it is damaged, damp and deformed, and pay attention to some relevant test reports and certificates. It is necessary to ensure that the surface of the gypsum board is smooth and flat, and pay attention to its surface stains, color and other problems.

4) Pay attention to whether the texture of the drywall is uniform.

When choosing gypsum board, you must pay attention to its texture, which can be identified by listening to the sound. Hit it by hand, if the sound is very strong and low, it means that the texture of the gypsum board is uniform; If the sound emitted by the drywall is particularly empty, it indicates that there is a hollow in the drywall.

5) Check the flatness and right-angle deviation of the macro drain balance gypsum board.

The flatness and right-angle deviation of gypsum board are very small, so the selection of gypsum board should also pay attention to check whether its flatness and right-angle deviation error is large.

1. When buying gypsum board, we need to observe its logo, generally each gypsum board packaging bag will have a trademark, name, quality grade, production date, manufacturer and product mark, etc., so you must pay attention to these marks when buying.

2. When buying sail Zhao gypsum board, we can directly use our hands to knock on the gypsum board, if the sound heard is very solid, then the surface of this gypsum board is durable, on the contrary, it is not.

3. When buying gypsum board, we can go to a good position to observe whether the front of the board has missing corners, stains, holes, cracks, incomplete patterns and uneven colors. In addition, you can also observe its side to see if its texture is dense and whether there is a hollow drum, and you must know that the denser the gypsum board with the car, the better it is to use.

The above is an introduction to the gypsum board purchase skills, I hope it will help you.

1. To see the brand and product logo of gypsum board, the choice of gypsum board must identify the big brand, the quality of the big brand of gypsum board is excellent, to ensure the normal progress of the project, choose a regular gypsum board, but also need to see the logo of the product, generally in the gypsum board packaging box will be marked with a very clear product name, production date and quality level.

2. To see whether the size of the gypsum board has deviation, gypsum board should pay attention to the size when purchasing, the actual size of the gypsum board is actually more or less the normal standard size will have deviations, if the deviation is small, the quality of the gypsum board will be good, if the deviation is very large, the use of gypsum on the way will expose a lot of problems, and the joints are not complete.

3.

5. Check the flatness and right-angle deviation of gypsum board, the flatness and right-angle deviation of good quality gypsum board are very small, if the flatness and right-angle deviation size deviation are very large, then there will be a problem of poor quality of gypsum board.
