The Reason Why We Need  To Distinguish The Two Types Of Drywall Vs Plaster How To Tell

You need to Distinguish The Two Types Of Drywall Vs Plaster How To Tell. However, you do not have any information about this product yet. This will make you ask a lot of questions. The first is definitely the definition.

What is drywall?

Drywall partitions are walls consisting of ribs and plasterboard used instead of cement walls to separate spaces in the house.

Drywall is made up of materials including: Metal skeleton, plaster cover, paint and auxiliary materials.

The structure of plaster is that people use an internal bearing skeleton, covered with plaster that is assembled, painted, and can withstand water.

  • The internal bearing frame is made of metal which works to create a solid structural system to catch on the floor through the keels and screws.
  • Gypsum board has the effect of creating a plane for the wall, gypsum boards are directly linked to the frame system through specialized screws and auxiliary materials
  • Putty and paint: This is the outermost layer for drywall, creating smoothness and creating aesthetics.

In addition, people can add some other materials to fill the outside such as glass wool, neoprene sheet to limit noise and prevent fire.

What is plaster?

From many sources, the concept of gypsum is understood as follows: It is known in English as Calcium Dihydrate, this is a sedimentary or weathered mineral with soft characteristics.

Gypsum is crystalline powder containing calcium sulphate salt containing 2 parts of water (formula is CaSO4.2H2O); has a density of 2.31 – 2.33 g/cm³.

From this it follows that plaster consists of drywall. Drywall is what is made from plaster powder in general.

There Are Many Ways To Limit The Confusion

Just because the meanings of the two words are almost the same, there are a few frequent mistakes that lead to confusion about drywall vs plaster how to tell. In this section I will share more information with you.

There are many ways to reduce this misunderstanding. However, the only and most important way I want to mention is that you have to be observant to distinguish the two.

Step By Step To Distinguish The Two Types Of Drywall Vs Plaster How To Tell

This is the most important part of the article, it helps you to Distinguish The Two Types Of Drywall Vs Plaster How To Tell. Please follow the steps below:

Step 1: Observe

This is the most important step for you to be able to distinguish between drywall and plaster. You note the powder form is plaster. Objects in the form of slabs and blocks are drywall.

Step 2: Uses


Another application that is in the field of home decoration is the main material in the statue and sculpture industry.

With the steps of creating a mold, pouring jelly into the mold, sculpting and finishing the statue is a process that requires careful and meticulousness.

When using statue casting, if using monolithic plaster, the worker must grind it into a powder, then proceed to mix the water in the correct ratio.

To ensure the hardness and make the product sturdy during use, the artisan will pour and apply two layers of plaster to the statue. Then from there refine and produce the finished product.

We often hear some information that people use gypsum in food such as tofu, tofu, etc.

But do not be confused because there is a separate type of plaster used in the food industry, if used in small doses, it is at a safe level, it is called phi plaster.


The drywall ceiling is composed of a skeleton system and gypsum boards to divide space and decorate the interior.

Drywall board for ceiling 

Drywall ceiling is a popular material to replace traditional ceilings such as cement ceilings, wooden ceilings. Gypsum ceiling prices are also cheaper than other types of ceilings.

There are two types of gypsum ceiling: floating ceiling and sunken ceiling. Floating ceilings have the advantage of being easy to disassemble and repair. Sunken ceilings have aesthetic advantages.

  • A sunken ceiling is a type of ceiling with a skeleton structure that is completely hidden above the plasterboards, we cannot see these skeletons. The ceiling can create a variety of patterns, which is convenient for designing many beautiful gypsum ceiling models according to each need.
  • Floating ceiling is a type of ceiling designed with a part of the bone bar exposed, often used to cover technical details such as power lines, water pipes, … under concrete or corrugated iron roofs, tile roofs.
Plasterboard for partition wall

These are structural walls consisting of an internal bearing plaster skeleton. The exterior is covered with plaster that is directly linked to the frame system through specialized screws. The outermost layer of paint creates smoothness and creates an aesthetic for drywall.

These plasterboards are used instead of cement walls. Helps separate indoor spaces with the advantage of lightness, aesthetics, suitable for many spaces.


After you can Distinguish The Two Types Of Drywall Vs Plaster How To Tell. You have teher interested in it and need to find out information about its use or any information. Then what can help you.

1. What are the pros and cons of drywall?

Advantages of drywall partitions

Lightweight plasterboard partitions

Plasterboard partitions are much lighter than brick wall partitions, bringing many convenient roles Lightweight: Gypsum partitions are 8-10 times lighter in weight than ordinary walls, making the weight heavier on the surface during the process. construction process, saving materials, reducing costs

Ease of construction and assembly
  • Drywall partitions are made from pieces of wall of all sizes that are easy to assemble and peel off depending on space and usage needs. Because of their lightweight characteristics, they are easy to disassemble, move and install quickly.
  • An advantage for homeowners when using drywall is its flexibility and ease of change. You can change the shape of the house, the room according to an initiative, a new idea if you want to change the space a little bit.
Save time and cost in construction
  • Using drywall instead of cement or conventional wall tiles will save up to 7% of the cost/total cost – applied to 25-storey buildings – The total savings in construction time management costs, foundation structure costs… (Source: based on research by Meihhardt and Saint-Gobain Vietnam, 2009).
  • Drywall has a rich design, smooth and flat surface, easy to combine with other interior decoration items, bringing its own aesthetic beauty to each owner.
  • Plasterboard partitions also have outstanding features of gypsum materials that are safe for human health, environmentally friendly, and do not contain harmful chemicals.
  • Drywall partitions are quite durable, if followed a solid process can be up to over 10 years.

Disadvantages of drywall partitions

  • We are known for many outstanding advantages of drywall, please take a look at some of its disadvantages for careful consideration before choosing drywall as a construction material.
  • Plasterboard partitions are easily yellowed if soaked in water, making the overall aesthetic unsightly. Therefore, you should not install drywall in places that are easily exposed to water.
  • Plasterboard partitions have a hollow structure inside, so the load will not be as strong as ordinary brick walls. You should avoid picking up sharp objects on drywall or hanging or hooking heavy objects up, to avoid breakage or damage
  • When used for a long time, Due to the impact of temperature, drywall may shrink, causing cracks, so it should be handled promptly if there are signs of cracking.
  • The level of impact resistance is not as good as a normal partition. Just a strong impact will easily cause damage, warping, and loss of aesthetics of the partition.

2.What are the uses of drywall?

Plasterboard partitions are easy to install and disassemble

The first feature of drywall is that it is easy to install and disassemble.

Regarding construction, instead of having to put cement, stack each brick and wait for the cement to dry, with drywall partitions, we just need to install the skeleton system and then install the plasterboard, extremely fast. Fast, easy and safe time.

In addition, when it needs to be repaired or relocated, it will be much easier than having to destroy the wall and rebuild it if using a brick wall.

Good soundproofing ensures quiet

Sound insulation is one of the typical features of drywall partitions. The sound insulation coefficient of standard drywall is 45dB and can reach 65dB.

Using drywall partitions for the bedroom will ensure quiet, helping to bring an absolute relaxation space for you and your family.

For apartments and offices, soundproofing is also an essential element to ensure comfortable and efficient living and working space.

Drywall partition against heat – effective fire resistance

The next outstanding feature of drywall is an effective insulation partition, which helps to reduce energy consumption for air conditioning equipment.

In addition, fire resistance is also a remarkable feature if we use a gypsum board to make partitions. Heat resistance in case of fire of drywall system can be up to 2 hours, limiting smoke and fire spread, helping to minimize damage to people and properties.

Drywall ensures aesthetics

Unlike brick walls, after construction, they must be sanded with a layer of cement, then whitewashed and then painted. The plaster surface with its smooth nature allows painting, wallpapering or tiled directly on the wall surface.

Besides, the gypsum board is also easy to cut, shape, make into flexible lines to not only perform the function of dividing space but also play the role of decorating the room more elegantly.

Drywall can separate the living room and the kitchen so you will have more space to store things in the living room or kitchen before or behind the partition such as TV, tables and chairs, etc.

3.How to distinguish good plaster?

If shaping the plaster ceiling plays the role of helping to create a highlight for the overall living space, the drywall is the factor that makes that highlight harmonious and sharp. However, this can also happen quite the opposite if you choose poor quality drywall. In order not to fall into this tragedy, below, let’s learn about how to distinguish and recognize good drywall.

With the ability to transform diverse spatial structures, quick construction time, and outstanding aesthetics, plaster lines are increasingly used in modern architecture.

Quality drywall

To distinguish what is quality drywall, first of all, we need to understand the basic information about gypsum mortar.

This type of barn is made up of gypsum powder. Gypsum powder is ground from gypsum minerals after this mineral is fired at a temperature of 105-150 degrees Celsius. Next, using gypsum powder mixed with water at a ratio of 50/50, we obtain gypsum mortar in liquid form. After about 3 to 5 minutes of solidification, we get a complete mortar.

To ensure the quality of mortar, you need to note that the ratio of water is inversely proportional to the curing time and the hardness of the mortar. When finished, gypsum mortar is used to form drywall.

In terms of form, standard drywall is beautiful, white and smooth. As for the composition, good drywall is a type of wall with a core made of fiberglass, while poor drywall is a wall with a core of jute fiber.

Besides, you can also recognize the quality of drywall thanks to the glue, and the connection between the drywall and the house wall. After a period of use, if the drywall does not split when the climate or weather changes, it means you have chosen to buy a good material.

In order for drywall to achieve maximum durability, besides choosing to buy quality materials, you also need to choose a reputable, professional, and methodical construction unit in the right process. Operating on the principle of putting customers’ interests first, drywall ceiling is the ideal destination for your project.

4. How to fix drywall to the wall?

Drywall is rightly recognized as one of the most popular and sought-after materials. This is due to its affordability and ease of operation. It is often used for leveling floors in houses. Today we will talk about how you can attach drywall to the wall, as well as get acquainted with all the pros and cons of this common finishing material.

Drywall is a finishing material consisting of two layers of cardboard with hard plaster and a special filler inside. It is used for many different purposes. For different constructions, plates of different thicknesses are made. Laying drywall sheets is possible not only on the walls, but also on the floor or ceiling. The main thing is to choose materials of the appropriate type.


  • glue;
  • plumb, special wire mark, tape measure, length ruler, pencil to mark the walls and control competent about the verticality of the surface;
  • spoon ;
  • the binder composition;
  • screwdriver;
  • punching machine;
  • dowels;
  • screw;
  • rollers;
  • soft brushes;
  • Planers;
  • putties.


It is a multi-use product. This product is used to solidify positions in the home or construction site.

Wooden house

Drywall can be used in many places. However, with houses made of straw or earth or wood, it is difficult to take advantage of because it is not suitable for use in that environment.

Brick house

Drywall is often used as an alternative to brick walls when you don’t want to use bricks and cement to separate rooms or spaces in your home.

It has the advantage of being able to be as long as you want, like a wall without worrying about height.

Adobe House

Drywall is a popular choice in the construction of many buildings or offices because it has many benefits, so it is said to be the most ideal type of room partition today.

Conditions to be observed

  • no mold or mildew on the rough floor;
  • there are also no dilapidated areas;
  • the wall must not be cold;
  • they must be protected from moisture and excessive moisture;
  • It is necessary to remove the old finishing materials from the surface of the walls, as well as dirt, and any other contaminants.

5. What are the characteristics of the sheet/drywall?

Gypsum has a smooth, flat, beautiful surface, easy to decorate and has good hardness, easy to join the panels together, the wall and ceiling will be very smooth. Furthermore, because the surface of the plasterboard is smoother than all concrete walls, it gives the house a remarkable appearance. After finishing the decoration, it is possible to use hand paint or spray paint or other decorations such as wallpaper or decorative tiles.

The organic property of the gypsum board is flexible so it won’t crack even after a long time of use, which is a significant advantage in using a gypsum board for construction projects. Gypsum boards can also be easily applied to warped ceilings and walls. Heat and sound insulation.

In addition, the gypsum board has very good fire resistance and insulation. It does not absorb heat and has a lower heat conduction rate than other materials such as concrete, brick, glass, etc. Therefore, the gypsum board can prevent heat and reduce energy consumption for the air conditioning system. peace.

Because of its insulating properties, the gypsum board is widely used for interior ceilings and walls to prevent fires. Furthermore, it is also very often used as the outer covering of high-rise structures to prevent damage in the event of a fire. Gypsum board is capable of withstanding fire for more than 3 hours.

Another function is soundproofing. The Gypsum board has the ability to reduce sound from about 35-60dB. This is the reason why theaters, factories… often choose gypsum board for soundproofing systems.

6. Is plaster edible?

Dr. Tran Bich Lam, lecturer in food technology, department of chemical engineering, Ho Chi Minh City University of Technology, affirmed: “The plaster itself is a non-toxic substance.”

Accordingly, gypsum has the chemical name of calcium carbonate (CaCO3), which is a substance that is allowed to be used in food and many other fields such as dentistry, fine arts, jewelry, etc.

To use in food, gypsum has to go through a rather complicated refining process, many stages such as calcination, dissolution, precipitation… Minimum purity must reach 98%, if using gypsum mixed with other ingredients. Many impurities cause disease.

Just like the decision No. 3742/2001 QD-BYT dated August 31, 2001 of the Ministry of Health on promulgating the “Regulation on the list of additives allowed to be used in food”, CaCO3 is a food additive with functional properties. The ability to adjust acidity, emulsification, anti-caking, stability.

7. What is the application of gypsum in production?

The production technology of foam plaster is quite complicated, conducted according to the following steps:

– Manufacturing technical foam.

– Mix gypsum powder and additives.

– Mix plaster mortar with foam and shape.

The physico-mechanical and thermophysical properties of foam plaster depend on many factors: the proportion of water, gypsum powder, additives, the amount of foam and the foaming technology (size and stability of the foam). Foam plaster is made into sheets from pouring or injecting a mixture into a mold, then it can be left whole or cut into small sheets of different sizes depending on use requirements.

The production technology of foam plaster has been successfully researched and applied in our country. However, the production of foam gypsum is more complicated than gypsum in gaseous form because the foam source is mainly imported.

Besides, hollowing for lightweight plaster can be done by using fiber reinforcement (usually glass fiber). The interweaving of scalar fibers in plaster will form voids. To increase the efficiency of creating voids, it is often used in combination with foaming agents.

The strength of fiber-reinforced lightweight plaster is heat insulation, flexural strength, good impact resistance, and high toughness. Therefore, they are very suitable for structures that need heat and sound insulation, and at the same time withstand bending or impact. The presence of fibers significantly reduces the volumetric variation of lightweight plasters during hardening or due to temperature or humidity changes. This increases the life of the fiber reinforced plaster.

Fiber reinforcement used in ultralight plaster has many types. But the most popular are fiberglass cotton, asbestos fibers, synthetic fibers… In general, these fibers have high strength and adhesion ability.

Currently, successfully manufacturing fiberglass reinforced plaster in general and lightweight plaster in particular and other types used in construction and interior decoration mainly in the form of panels and partitions. This type has a volumetric weight of about 1000-1600 kg/m3, compressive strength 10-12 Mpa, tensile strength 4-6 Mpa.

The above are some of the most common types of lightweight plaster, they are widely used in the construction industry and interior decoration design, constantly developing both in the country and in the world with many types, sizes and usability. In the hot and humid tropical climate, the use of super light plaster for construction works will bring great technical efficiency.
